replication question

2002-03-04 Thread Bunyamin K. Karadeniz



Dear Gurus,
The clients will enter records to a database all 
day and I will update the other database . 
I need to replicate 10 tables in a database to 
other database at a specific time. 

Do I need Advanced replication or basic 
replication . ?
How can I understand that replication is supported 
in my both databases. ?

RE: Manager decrees his data warehouse design. Help!

Hello Dennis

You missed the point.

If we could make the transition, sometimes lead it,
from punch cards to internet we can do ANYTHING.

I was leading the transition from cards to diskettes, to online work
and to the use of database in my previous employment.
In my current employment, after 15 years in ADABAS on MF
I am leading the oracle team here, on NT.

Those young Turks out there are specialist that may
or may not adjust to a new environment.
We have already proven ourselves.

Hi Hemant,

Thanks for your help. I've checked the metalink for Installation Guide. I
found a copy Oracle8I Release Notes Release 3 (8.1.7) for Sun SPARC solaris
Part Number A86565-01. Our OS has the following SUNWarc, SUNWbtool, SUNWhea,
SUNWlibm, SUNWlibms, SUNWsprot, SUNWtoo packages but the executables ld and
make are not in the /usr/ccs/bin directory.

Our UNIX administrator is trying to add in another package SUNWbtoox.
Hopefully, make and ld will be installed in the /usr/ccs/bin directory. I
will keep you inform.

would be similar in Solaris 8.

Operating System Patch
Use the latest kernel patch from Sun Microsystems. Sun
provides patch information at:
http://sunsolve.sun.com
Solaris 2.6 requires at least kernel jumbo patch revision
#105181-15 for successful installation of Release 3 (8.1.7).

Window Manager
X-windows must be installed on the system from where the
Installer is run. Use any Sun-supported X-windows server, for
example, dtwm, twm, olwm, that supports Motif.
Character mode installs are not supported for Release 3 (8.1.7).

Re: Perf Advice Needed: cache buffers chains, high waits, _db_block_hash_buckets

2002-03-04 Thread Jonathan Lewis


Don't forget that Oracle has redesigned the whole
area of hash buckets and hash latches.

In 8.1, the number of buckets is roughly 2 x db_block_buffers,
but each latch covers multiple buckets (don't forget that
a latch is about 160 bytes, so a noticeable amount of
memory overhead)

Because each latch covers multiple buckets, the latches
can be held for a short time, as they need only be held
whilst one bucket is searched.  Unfortunately, there is no
easy way to see the number of buffered blocks per bucket.

Steve Adams has a formula relating db_block_buffers to the
number of latches, but for most reasonable sized database,
the answer is 1024.  Typically you are likely to see between 64
and 128 buffers per latch.

Seperating indexes and tables

2002-03-04 Thread Jack van Zanen

Hi All,


I used to learn that due to performance reasons (disk head going back and
forth) indexes need to be seperated from tables (different
disks/controllers).
Later I have heard other people say that this is not an issue because the
disk head does not stop and wait for you on a production system with normal
activity. The reason for seperating indexes and tables now only done for
administrating purposes.

I tend to lean towards the second opinion but would like to have your
opinion on this


TIA

Re: replication question

2002-03-04 Thread Rahul Dandekar



Depends on your need.
You can have read only snapshots, updatable 
snapshots
or multimaster...
Again if you think of multimaster... then you would 
need to make decision
based on your application requirements about sync 
or async

I donot have any expereince of snapshot 
replication.
But, if you are planning multimaster replication, 
then better
spend a couple of months studying it and testing on 
test boxes...

Make 100% sure that your applicationreally 
needs the replication
and there is no other simpler 
option...

Just 2 cents...

There should not be any problem to test the backup.

Re: Seperating indexes and tables

2002-03-04 Thread Connor McDonald

Basically separating data and indexes is a special
case of separating disparate IO operations to achieve
sensible load balancing across your IO subsystem.

Its a little obsolete - basically being a throwback to
the days when Oracle did nested loops and not much
else.  Nowadays, with operations that could be
parallel, fast full scans, index joins, etc etc, it
could be a more complicated exercise.

Unless you're in a high end environment, a reasonable
compromise is spreading all the database across one or
more stripe sets.

Re: New iMac as dba workstation

I'm using a Titanium G4 as a workstation, does that count?  ;)

I've had marginal luck using products like SQLGrinder (native OSX app, 
uses JDBC for connectivity).  Ultimately though, I fell back to using 
Tora X-forwarded back to my box (I'm running XDarwin on top of Agua).  I

This is all part of a grand experiment, and I have to say that for me

RE: Planning Test Backup/Recovery

2002-03-04 Thread Mercadante, Thomas F

Eriovaldo,

If I were you, I would create a small test database on the production
machine, and perform backup/restore of that test database to be sure that
everything is working before I would try it on a production database.

Once you are convinced that everything works, schedule a down time where you
can test backup/restore of the production database.

I would also keep the test db on the production box, and as a regular
monthly schedule, test backup and restore of that database - just to make
sure that it continues to work.

Hope this helps.

There should not be any problem to test the backup.
However we are testing the restores to another machine,
not on the production machine.

RE: replication question

The 
way I see it . the question comes down to whether or not you need two 
way replication or just one way. If both databases can update those 
tables and you need them synced between the databases then Advanced Replication 
would be the route. If all you need are data changes from 1 database 
to be replicated to another database then simple replication is all you 
need.

Making rule-based optimizer choose correct index

2002-03-04 Thread Frederik Lindberg

Hi,

I'm trying to do a join that is best done by a fast full scan of one
index and a lookup in another. Using the rule-based optimizer and
Oracle 8.1.6, I can't get the optimizer to do what I want. Is there a
way? Any enlightenment would be greatly appreciated.

[Yes, we are moving to cost-based, but some applications need
straightening out first).

- details ---
TABLE U
-UID number,
-EMAIL varchar2(100),
-CLIENT_ID number

unique index on (UID,EMAIL,CLIENT_ID)

TABLE D
-UID number
... lots of data columns

unique index on UID

Query: select D.UID,U.EMAIL from U,D where U.UID = D.UID (so in
essence, I want the UID-EMAIL translation for all UID that exist in
the D table).

The optimizer does a table access full on D and a range scan on the U
table index. Same query with /*+ INDEX_FFS(D-index) */ results in a
fast full scan of the _U_ index followed by a unique scan of the D
index. Adding nonsense criteria such as ... and D.UID  0 doesn't
make things better.

The D table is very wide, so a lot of I/O is wasted by doing a full
table scan.

Thanks!

RE: Changing the SID of a database

2002-03-04 Thread SARKAR, Samir

Take a backup of the controlfile statement by doing a 

 alter system backup controlfile to trace;

Then use this script to create a new controlfile with the new SID
after u have transferred all the datafiles, redolog files and archive
log files. The first line of the create controlfile script may look 
aomething like :

 CREATE CONTROLFILE REUSE SET DATABASE NAME OF NEW DB RESETLOGS
ARCHIVELOG

Change the path of the log files and other datafiles in the script if they
happen to
be different than the old database. Remember to run the create controlfile
script in 
nomount mode.

Remember to change the db_name parameter in ur parameter 
file for the new database. 

After creating the controlfile, startup the database using the resetlogs
option :

 alter database open resetlogs;

Hope this helps,

Re: Changing the SID of a database

2002-03-04 Thread Rachel Carmichael

it's doable. You will need to do a number of things before you can open
the database, including recreating the controlfile (to change the sid)
and renaming all the datafiles to new locations (so you don't overwrite
the original database)

The easiest way (but not the shortest time) to do this would be to do a
full database export, create the new database, with the SID you want
and all the tablespaces with the new datafiles, import the full export
with DESTROY=N and IGNORE=Y (this is VERY important! or you will
overwrite the original datafiles).

you can also export every user individually and import them into the
new database safest way but most time-consuming and biggest pain in
the butt way to do it

RE: help with a SQL self-join

If I understand correctly, it sounds like you need a *recursive* self-join.
Depending on the version of your db (certainly in 8i or later) you may be
able to use the CONNECT BY PRIOR syntax to get what you're after.

Have a look at the SQL reference for 'hierarchical queries'.  Here's a link
to the 9i docs:

I need help with a self-join.  I have two tables:  DEPT_TBL and TREENODE.

One table holds dept data.  Depts report to one another at at different 
levels, and are rolled-up for different purposes.  This roll-up 
information is stored in the TREENODE table.

Each tree_node in TREENODE has a corresponding PARENT_TREE_NUM, which 
corresponds to it's roll-up level.  DEPT_TBL holds dept ID and dept 
description, but no level information.  TREENODE holds tree_descriptions.

The a.deptid = b.tree_node, so that's a possible join.

Question:  How do I pull a dept ID and it's corresponding roll-up 
node/deptid?

This is what I have so far;

select DISTINCT a.tree_node DEPT, b.tree_node COLL
from treenode a, treenode b
where a.tree_node  b.tree_node
and a.tree_name = 'DEPT_SECURITY'
and a.tree_node = 'H0086'
and a.parent_node_num = b.parent_node_num;

this pulls a dept and all the depts that roll-up at the same level, but 
not the roll-up level.  For example, Dept 'H0086', and 27 depts that rollup 
at the same level.   I simply want a single row with two columns:  a deptID,

and a rollup ID.

How do I do this?

Any help is really appreciated.

Re: Changing the SID of a database

2002-03-04 Thread Bill Gentry

Rick, here is how I do it.  Contact me if there are any questions.


Make a copy of 'prod' on LAWDB to 'test' on LAWDB from Cold Backup

Introduction

The 'prod' Oracle instance sometimes need to be replicated, on demand, for
testing and/or training purposes. The replication is done using a 'Cold'
backup copy of the 'prod' instance using either the backup directory
(/dbkup) or the ADSM backup. The procedure is very much the same for
creating either 'test' or 'train'. This section will assume creating a 'test
' database.


Procedure

? Take a cold backup of 'prod'

? Shutdown 'test' instance

The 'test' instance should be shutdown using 'immediate' option.


ORACLE_SID=test

export ORACLE_SID

svrmgrl

SVRMGR connect / as sysdba;
connected;

SVRMGR select name from v$database;
NAME
-
TEST
1 row selected.

SVRMGR oradebug ipc

SVRMGR shutdown immediate;

SVRMGR exit;

? Copy the datafiles files from the cold backup

Delete ALL TEST database related files, i.e. *.dbf, *.ctl, *.log

Use the cold backup to copy the .dbf files to the test instance
mountpoints


? Re-create control files  redo logs for the test instance.
(See example belos)

Use the 'make control file' script

ORACLE_SID=test

export ORACLE_SID

cd $HOME/test/admin

svrmgrl

SVRMGR connect / as sysdba

SVRMGR @mkctrl

SVRMGR select name from v$database;



Example  of creating control files  redo logs:

STARTUP NOMOUNT
CREATE CONTROLFILE SET DATABASE lawtst5 RESETLOGS NOARCHIVELOG
MAXLOGFILES 32
MAXLOGMEMBERS 2
MAXDATAFILES 200
MAXINSTANCES 8
MAXLOGHISTORY 800
LOGFILE
  GROUP 1 '/db/u05/oradata/lawtst5/redo01.log'  SIZE 64M,
  GROUP 2 '/db/u06/oradata/lawtst5/redo02.log'  SIZE 64M,
  GROUP 3 '/db/u07/oradata/lawtst5/redo03.log'  SIZE 64M
DATAFILE
  '/db/u05/oradata/lawtst5/system01.dbf',

I've read
 that it's possible, but not how to do it. Is this an easy thing to do, or
would
 it be better to extract the tables and create the new db that way?

 Thanks for any help.

Multimaster Replication Doubt...

2002-03-04 Thread Rahul Dandekar

1.
It is my understanding that Oracle 7.x has continuous purge
of the propogated deftrans. There is no option of scheduling
periodic purge at specific time. Am I correct?

2.
How to schedule continuous purge of propogated deftrans in
Oracle 8i from command line?

prompt  SCHEDULE PURGE AT MASTER SITE 
BEGIN
DBMS_DEFER_SYS.SCHEDULE_PURGE (
NEXT_DATE = SYSDATE,
INTERVAL = 'SYSDATE + 1/24',
DELAY_SECONDS = 0,
ROLLBACK_SEGMENT = '');
END;
/

Manual says set DELAY_SECONDS to 500,000 and set INTERVAL to a value less
than
DELAY_SECONDS. I could not understand exactly how this works...

So, in your opinion i need to create a instance, in the production machine,

Eriovaldo,

If I were you, I would create a small test database on the production
machine, and perform backup/restore of that test database to be sure that
everything is working before I would try it on a production database.

Once you are convinced that everything works, schedule a down time where 
you
can test backup/restore of the production database.

I would also keep the test db on the production box, and as a regular
monthly schedule, test backup and restore of that database - just to make
sure that it continues to work.

Hope this helps.

Depends on your need.
You can have read only snapshots, updatable

or multimaster...
Again if you think of multimaster... then you 
would need to make decision
based on your application requirements about 
sync or async

I donot have any expereince of snapshot 
replication.
But, if you are planning multimaster 
replication, then better
spend a couple of months studying it and 
testing on test boxes...

Make 100% sure that your

and there is no other simpler 
option...

RE: Planning Test Backup/Recovery - Tom

2002-03-04 Thread Mercadante, Thomas F

Eriovaldo,

If you already have a backup script, then you need to test it on the
production machine.  The test db you create does not necessarily have to be
the same size as the production db (init.ora params can be smaller).  But
what you are testing is that your backup scripts run as expected on the
production machine.
  Your init.ora params can be smaller (like a smaller SGA) to prove that it
works ok.

Hope this helps

I am thinking something like that ..
I have already did the test at another machine ...
It worked right...

but the instance was diferente ...

So, in your opinion i need to create a instance, in the production machine, 
with the same parameters of production and apply the test there, righ ...

But , how can i to create a instance with the same parameters ?
Should i use the init.ora of the production instance ?

Eriovaldo,

If I were you, I would create a small test database on the production
machine, and perform backup/restore of that test database to be sure that
everything is working before I would try it on a production database.

Once you are convinced that everything works, schedule a down time where 
you
can test backup/restore of the production database.

I would also keep the test db on the production box, and as a regular
monthly schedule, test backup and restore of that database - just to make
sure that it continues to work.

Hope this helps.

RE: Linux for Big(ish) Databases

2002-03-04 Thread lembark



-- Jesse, Rich [EMAIL PROTECTED] on 03/04/02 09:03:28 -0800

 The problem with Linux on Sparc or Alpha is that Oracle doesn't have
 binaries for them.  I've requested Alpha binaries, but haven't had any
 response, despite the 1-2 business days response.  sigh

Remember: They're Oracle, you're not. Be glad they take
their precious time to not answer your questions!

The main problem with Intel boxes is a narrow I/O bus and
latency issues with the chipsets. The VIA set tends to be
faster so far as I've seen. Combined with good SCSI boards
and LVM striping you can get decent throughput, but it'll
never match something like a V-box or 6500 for full-bore
speed. The real alpha motherboards (not NT compatable
toys) use wide I/O channels to keep the chip fed.

If you're considering linux look carefully at clusters.
They can be an immense help dealing with large databases.

Automatic PGA Memory Management via PGA_AGGREGATE_TARGET paramete

2002-03-04 Thread David Wagoner








I just stumbled upon the Automatic PGA Memory Management section of
the 9i docs. Ive never heard of
this before. Does anyone know how
long its been around? Anyone
using it found any bugs, concerns, etc.?



Granted, this is intended for *dedicated* server mode, it seems
like a good option for our Test databases and perhaps other databases that have
only a handful of users and dont require MTS. By setting PGA_AGGREGATE_TARGET=X, where X can be a value in
K, M, or G, Oracle will automatically distribute this memory allocation to
dedicated sessions instead of using SORT_AREA_SIZE. Heres an excerpt from the docs:



Oracle does
not recommend using the SORT_AREA_SIZE parameter unless the instance is
configured with the shared server option.
Oracle recommends that you enable automatic sizing of SQL working areas
by setting PGA_AGGREGATE_TARGET instead. SORT_AREA_SIZE is retained for backward compatibility.

RE: replication question

2002-03-04 Thread Kevin Lange



I have 
used both. 

Replication, like archive log movement , happens whenever you set it up 
to happen. That can be anywhere from every minute to once a day to 
beyond. It just depends on your needs. In the case of my old job, we 
had replication happeningat different times for different 
tables. Our key table was replicating IMMEDIATELY uponany 
changes to the parent table. This happened via 
trigger.Other , not so important tables, would replicate at 
anywhere from 30 to 60 
minutes. We did this using scheduled jobs.

I see 
two realnice advantages ofreplicated databases. One, they are 
accessible.i.e. you can run reports, queries, etc on them. 
They are nothing more than instancesthat get updated via a foreign 
database. Two,depending on what kind of software you use, you can 
update the database from an outside source. We used to have data 
sent down from our DB2 database into our Oracle database using an oracle product 
called Replication Services (nothing more than triggers and a specific data 
structure) and an IBM product called Data Propogator. 

Archive log transport for standbys can happen in 
multiple ways also. The newer oracle versions support direct archiving 
from a production database to a standby database. I have not tried this 
yet but we are looking into it. Our current standby databases are 
brought up to date with a shell script that is scheduled via cron every 20 
minutes.

The thing about the standbys, they areall or 
nothing ... you can not just say I want only tables 1-10 to be updated. 
They all are. Also, in the older oracle versions, the standbys could not 
be accessed via software so you could not use them as any sort of read only 
database. This is not the case in a replicated database. But, 
they are also very easy to rebuild and resetup. Just copy your production 
files over, create a standby control file, and bring the databse up in standby 
mode. Very easy.

Now... which would I recommend ??? Depends 
on your needs.

If you really need to access that copy of the database 
for other purposes and you only want certain tables to be updated, then I would 
consider replication. If, on the other hand, you do not have to 
access the data (until such a time as your production gets killed and you need 
your standby up) and you need a fast way to rebuild the second database, I would 
suggest the Standby approach.

you need are data changes from 1 database to be replicated to another

Re: replication question

2002-03-04 Thread Rahul Dandekar



Well, you could open standby DB only for 
read only access (8i) whereas in replication, both or
all (more than 2) databases could be up 
and open to users all the times.

Each DML causes substantial overhead as 
each transaction needs to be propogated and applied
at all the master sites (whereas 
inOracle Parallel Server,there is centralized database accessed 

by multiple instances, there is no need 
for this).

So, if you donot need two databases at two 
geographically separate locations, open for users,
then Standby DB or OPSmight be 
better option. Again, in OPS, if the hardware cluster fails then
you are in trouble...

About speed, if you could tune up sending 
of logs and application of it, then Standby database
would consume substantially lesser 
resources than replication, hence higher throughput...
The primary database in Standby DB just 
needs to send the archivelogs (simple file transfer)
and then log application happens on the 
secondary server...
Whereas, in replication, the database 
would have to propogate and apply each and every
transaction individually

The way I see it . the question comes down to whether or 
not you need two way replication or just one way. If both 
databases can update those tables and you need them synced between the 
databases then Advanced Replication would be the route. If all 
you need are data changes from 1 database to be replicated to another 
database then simple replication is all you need.

RE: EXTENTS?

2002-03-04 Thread Mercadante, Thomas F

Seema,

You got it backwards.

If Db Block Size is 8k, and you create a table with it's initial extent of
32k, the you have 4 db blocks making up the extent.

An Extent is composed of one or more Db Blocks.  A Db Block is defined when
you create the db (although I heard that different tablespaces can have
different Db Block sizes in 9i - correct anybody?)

Hope this helps.

RE: EXTENTS?

nick, you're thinking segments not extents.

and I was off as well, if your extent size is less than the blocksize
then you can have more than one extent in a block (divide the block
size by the extent size and round DOWN)

in general though, extents are not usually sized as small as the
database block size

Re: TABLE SIZE?

2002-03-04 Thread Ora NT DBA

This would be true if and only if you ignored block header space and ignored
free space in blocks.

What do you want to know

The number of blocks under the high water mark?

The total size of extents allocated to the table segment?

The space allocated within those blocks?

The total number of blocks allocated to the table?

Any one of these could be answered none of them would be the answer you 
arrived at.

RE: How TO KNOW TABLE SIZE

Check this note from metalink.


***

Title: Script to compute table size

Disclaimer:
This script is provided for educational purposes only. It is NOT
supported by Oracle Support Services.  The script has been
tested and appears to work as intended.  However, you should always
test any script before relying on it.

PROOFREAD THIS SCRIPT PRIOR TO USING IT!  Due to differences in the
way text editors, email packages and operating systems handle text
formatting (spaces, tabs and carriage returns), this script may not
be in an executable state when you first receive it.  Check over the 
script to ensure that errors of this type are corrected.

Abstract:
It is sometimes necessary to calculate the exact size (exact 
number of bytes) of a table. 

The function 'VSIZE' gives the exact number of bytes allocated
by Oracle for data.
 
For example, if you have a table called 'table1' with n columns  
say, 'col1', 'col2',  , 'coln', execute the following SQL
statement to find the exact size of the table:
  
SELECT SUM(VSIZE(col1)) + SUM(VSIZE(col2)) + ... + 
   SUM(VSIZE(coln)) FROM table1;

In the scott/tiger schema, the following SQL statement can be
executed to find the exact table size of the 'DEPT' table:

SQL SELECT SUM(VSIZE(deptno)) + SUM(VSIZE(dname)) +
 SUM(VSIZE(loc)) FROM dept;

SUM(VSIZE(DEPTNO))+SUM(VSIZE(DNAME))+SUM(VSIZE(LOC))

 88
Requirements:
None

Version Testing:
This script was tested on Oracle 7.3.3 to 8.1.6 and SQL*Plus

nick, you're thinking segments not extents.

and I was off as well, if your extent size is less than the blocksize
then you can have more than one extent in a block (divide the block
size by the extent size and round DOWN)

in general though, extents are not usually sized as small as the
database block size

 Hi
 If DB block size is 8k then how many extents in one db block?

Sun Cluster and VCS failover

2002-03-04 Thread Nick Wagner



Situation: Sun 
Cluster, or VERITAS Cluster. Oracle 8, 8i, or 9i
2 node Sun E6500s w/ 
8 CPUs

If the primary node 
fails, how long does it take before a user is able to connect to the secondary 
node, and continue their activity? I'm sure reality, and marketing 
times are different... I'm really interested in reality times, but at this point 
either would be nice. 

Thanks!!

RE: LIKE and % operator

David,

If you have General with an upper case G and are looking for general with a lower case 
g, you won't return any records. It's that old case sensitive thing.

Try this:

select * from sonusrpt where Upper(subject) like '%GENERAL%';

Defaults for ANALYZE

2002-03-04 Thread Jesse, Rich

Hi all,

From my testing in 8.1.6 and 8.1.7, it appears to me that the ANALYZE
defaults to FOR ALL COLUMNS SIZE 1.  I found this by checking the
DBA_TAB_HISTOGRAMS view before and after an ANALYZE TABLE bleah COMPUTE
STATISTICS.  I then compared those results to a before/after using
DBMS_STATS first with METHOD_OPT = NULL, then METHOD_OPT = 'FOR ALL
COLUMNS SIZE 1'.

So, can anyone tell me where the hell this is documented for the ANALYZE
command?  It's not in Oracle8i SQL Reference under ANALYZE, where one
would think it should be, nor does it show up in a search on
http://tahiti.oracle.com.  Same for Metaclink.

I've been pulling my hair out trying to determine why I've been getting
different explain plans between DBMS_STATS and ANALYZE, until I discovered
this.  DBA need beer.  One Three Floyd's left in fridge.  M...

There was no specific

our problem.

Has anyone seen this error on 8.1.7 before?

RE: EXTENTS?

2002-03-04 Thread Jack C. Applewhite

Yes, this one will get a lot of traffic, I'll bet.

I just looked in the 8.1.7 docs (SQL Reference - Storage Clause) and it says
that the minimum INITIAL is 2 DB blocks for non-bitmapped segments, 3 for
bitmapped segments.  The minimum for NEXT is 1 DB block.

Unlesss it's a new 9i feature, a DB block can belong to one and only one
Extent.

Re:how are the snapshots refreshed ?

2002-03-04 Thread dgoulet

Bunyamin,

OK, some of this may be a little off the wall since I'm at home on a day
off.  Can't believe I'm answering the mail on a day off!!  But you got to do
something while waiting for the glue to dry!!

Anyway, there are two init parameters that need to be set,
job_queue_interval and job_queue_processes.  After that bounce your database to
start things.  There after, the parameters you set for 'next' will take over. 
Now if you need to make changes, look in the user_jobs table.  There you will
find the next_date column and a procedure dbms_job.next_date to adjust matters.

I just stumbled upon the Automatic PGA Memory Management section of the 9i
docs.  I've never heard of this before.  Does anyone know how long it's been
around?  Anyone using it found any bugs, concerns, etc.?



Granted, this is intended for *dedicated* server mode, it seems like a good
option for our Test databases and perhaps other databases that have only a
handful of users and don't require MTS.  By setting PGA_AGGREGATE_TARGET=X,
where X can be a value in K, M, or G, Oracle will automatically distribute
this memory allocation to dedicated sessions instead of using
SORT_AREA_SIZE.  Here's an excerpt from the docs:



Oracle does not recommend using the SORT_AREA_SIZE parameter unless the
instance is configured with the shared server option.  Oracle recommends
that you enable automatic sizing of SQL working areas by setting
PGA_AGGREGATE_TARGET instead.  SORT_AREA_SIZE is retained for backward
compatibility.

RE: replication question

Thanks

Great, 
quick response.

  ORACLE-LSubject: RE: replication question
  I 
  have used both. 
  
  Replication, like archive log movement , happens whenever you set it up 
  to happen. That can be anywhere from every minute to once a day to 
  beyond. It just depends on your needs. In the case of my old job, 
  we had replication happeningat different times for different 
  tables. Our key table was replicating IMMEDIATELY uponany 
  changes to the parent table. This happened via 
  trigger.Other , not so important tables, would replicate at 
  anywhere from 30 to 60 
  minutes. We did this using scheduled jobs.
  
  I 
  see two realnice advantages ofreplicated databases. One, 
  they are accessible.i.e. you can run reports, queries, etc on 
  them. They are nothing more than instancesthat get updated via a 
  foreign database. Two,depending on what kind of software you use, 
  you can update the database from an outside source. We used to 
  have data sent down from our DB2 database into our Oracle database using an 
  oracle product called Replication Services (nothing more than triggers and a 
  specific data structure) and an IBM product called Data Propogator. 
  
  
  Archive log transport for standbys can happen in 
  multiple ways also. The newer oracle versions support direct archiving 
  from a production database to a standby database. I have not tried this 
  yet but we are looking into it. Our current standby databases are 
  brought up to date with a shell script that is scheduled via cron every 20 
  minutes.
  
  The thing about the standbys, they areall or 
  nothing ... you can not just say I want only tables 1-10 to be updated. 
  They all are. Also, in the older oracle versions, the standbys could not 
  be accessed via software so you could not use them as any sort of read only 
  database. This is not the case in a replicated database. 
  But, they are also very easy to rebuild and resetup. Just copy your 
  production files over, create a standby control file, and bring the databse up 
  in standby mode. Very easy.
  
  Now... which would I recommend ??? 
  Depends on your needs.
  
  If you really need to access that copy of the 
  database for other purposes and you only want certain tables to be updated, 
  then I would consider replication. If, on the other hand, you do 
  not have to access the data (until such a time as your production gets killed 
  and you need your standby up) and you need a fast way to rebuild the second 
  database, I would suggest the Standby 
  approach.

  The way I see it . the question comes down to whether or 
  not you need two way replication or just one way. If both 
  databases can update those tables and you need them synced between the 
  databases then Advanced Replication would be the route. If all 
  you need are data changes from 1 database to be replicated to another 
  database then simple replication is all you need.

Depends on your need.
You can have read only snapshots, updatable 
snapshots
or multimaster...
Again if you think of multimaster... then 
you would need to make decision
based on your application requirements 
about sync or async

I donot have any expereince of snapshot 
replication.
But, if you are planning multimaster 
replication, then better
spend a couple of months studying it and 
testing on test boxes...

Make 100% sure that your 
applicationreally needs the replication
and there is no other simpler 
option...

SSL and non-SSL requests on same Apache server in 9iAS?

2002-03-04 Thread Ben Poels

Hi,

I want to host SSL and non-SSL requests on one physical server
running one 9iAS.

After installing 9iAS the httpd.conf file specifies by default
that it is listening on port . Later on in httpd.conf it 
has an SSL directive that says it's listening on port 80 and 443.
Does this mean that this one Apache server can service non-SSL
requests on  and SSL requests on 443 at the same time?

There is a document on Metalink(135231.1) that describes how to run two
Apache servers in one 9iAS home. Again what is not clear to me
is whether or not one could be handling SSL and the other non-SSL.

Anyone have any recommendations on how to do this? I may also be asked
to host 40-bit and 128-bit encryption on the same web site. Again any
recommendations?

Thanks.

Secret maximum for INITRANS?

2002-03-04 Thread Robert Eskridge

I'm still messing with my enqueue waits on an insert. I'm now able to
recreate it on a test database by throwing enough simultaneous inserts
at my table. I was going to make sure which of the tables/indexes was
actually causing the waits by individually raising the INITRANS above
what they would naturally expand to, and see how the waiting sessions
responded.

I was hitting it with 50 simultaneous inserts and usually had 10
sessions go into an enqueue wait until the 40 sessions committed or
rolled back.  So I was going though the indexes and then tables
raising the INITRANS to 50 to see which one(s) made a difference.
None of them made a difference.

So I dumped blocks that had been populated only during this exercise.
Invariably, there were 0x29 Itl slots.  Is there something out there
that would limit the Itl entries to 41 even when MAXTRANS=255?  Is
there some secret bound based on block size?  Ours is 2k (which I
figure is part of the problem).

Other vital stats:  8.0.5 on Solaris 2.7.

Hash Anti Join Requirements

2002-03-04 Thread Larry Elkins

Listers,

Some conditions have to be met before a HASH ANTI JOIN can be used (either
by hint or by setting always_anti_join=hash). The ones I have come across
are (1) the column in the NOT IN query must be NOT NULL (or constraining
criteria specified that says NOT NULL for the column, and that's probably
what you want anyway), and, (2) there cannot be more than one table in the
NOT IN sub-query (and we have workarounds for that as well -- flip into an
in-line view, use no_merge and use_hash if necessary, and use the outer-join
and key is null anti-join trick).

Here's what the docs say about the conditions:

The optimizer uses a nested loops algorithm for NOT IN subqueries by
default, unless the initialization parameter ALWAYS_ANTI_JOIN is set to
MERGE or HASH and various required conditions are met that allow the
transformation of the NOT IN subquery into a sort-merge or hash
anti-join...

Note the and various required conditions are met that allow the
transformation I've never found a source that specified those
conditions. I came up with the two conditions above based on experience but
even then I don't know they are set in stone.

I ask because I am working with some folks who are frightened by anti-joins.
And in their case, a lot of queries would benefit, and have been
demonstrated, from the use HASH-AJ's. I would just like to be able to give
them something more concrete about when a HASH-AJ is possible other than the
two things I listed above (which may or may not be true) and the generic
comment in the Oracle docs.

Read Consistency ITL's

2002-03-04 Thread Rajesh . Rao

Hello Gurus,

As I understand it. In order to provide a read consistent view of the data
while reading a data block, Oracle looks at the SCN in the block header,
and compares it to the snapshot of the SCN taken when the read commenced.
If the Snapshot SCN is less than the SCN in the block header, the query is
directed to read from the rollback segments.

For any transaction that modifies a block, the ITL among other things, also
stores the commit SCN and the address to the transaction table in the
rollback segment. Assume that the block has just one ITL. This ITL can be
reused once the transaction is completed. Assume it is. That is, two
transactions have performed updates on the block since our read commenced.
If so is the case, how does Oracle know which rollback segment to look at?
I am assuming it still looks at the ITL, rolls it back, sees that it needs
to rollback further, looks at the ITL in the rolled back block, and
rollsback further, and so on, until it can reconstruct the data block at an
SCN lower than the snapshot SCN. Is that right?

My second question is, what happens if the data block has two ITL's, both
marked with SCN's greater than when the read commenced. Which ITL does
Oracle look at to get the address of the rollback segment? Is it the one
with the least SCN??

And also, my previous question, remains unanswered so far? Why does Oracle
not allow one to grant select privileges on the fixed tables to any other
user?

Thanks
Raj

 If the primary node fails, how long does it take before a user is able to
 connect to the secondary node, and continue their activity? I'm sure
 reality, and marketing times are different... I'm really interested in
 reality times, but at this point either would be nice.

Forms6i (6.0.8 ?) on Motif Mode

2002-03-04 Thread hemantchitale


We have a number of Forms 4.5 environments (against 7.3.4/8.1.6/8.1.7)
where the clients are Unix workstations. Therefore, the Forms they are are
Motif-mode.

We are looking at upgrading to 6i.  Has anyone upgraded to 6i Motif
(ie convert, develop and run in Motif) ?

RE: Sun Cluster and VCS failover

2002-03-04 Thread hemantchitale


I would think 12 to 15 minutes still too high.  Damagement would generally
specify
a max of 5 minutes.

Have you found out why it takes 12 to 15 minutes ?  Do the File Systems
take so long or
does the Instance Recovery take so long ?  Do you have to put a sleep in
the startup
scripts  [when I setup a failover cluster for Oracle Apps with Oracle Web
Application Server 3.0.2,
I put in a sleep of 30seconds for the Web server -- WAS302 has to have the
physical host-name
hardcoded in the wrb.app file so I maintained two copies of the file and
the startup
script would copy in the correct one, depending on the hostname, as wrb.app
but
sometimes it wouldn't startup immediately ; I had to put a sleep after the
file copy].

On our SunCluster 2-node E4500's with 8 CPU's (Oracle 8.0.5)
it takes us around 12 to 15 minutes.

HTH.

# of datafiles per tablespace

2002-03-04 Thread Kimberly Smith

OK, I know we had the debate already but lets have another go at it.

Say you got a tablespace, lets call it RBS and its for rollbacks.
Now, for what reason would you create a 500M file and 4 50M files
for this puppy as opposed to just one file.  I just cannot see the reasoning
for this at all.  None.  Natta.  Zilch.

So educate me please if someone out there knows a legit reason they
would do this.

Lets assume for the sake of argument that disk size and mount point
size is not a limitation.  Space available to me on any one mount point
is unlimited.
