Weird behavior with VARCHAR fields (was: ORA-01403 error, help!!!)

2003-09-10 Thread Fermin Bernaus

Thank you all of you who answered to my first question.

No, the problem has nothing to do with permissions. The record existed in the 
table, but here it is what I discovered. Can anyone explain please? It may be the 
normal Oracle behavior, but I believe it was not working like this under 7.3.4 (now we 
have 8.0.3). I can not confirm though.

TTDSLS805501 table definition is as follows:

NameNull?   Type
T$ORNO  NOT NULLNUMBER
T$USER  NOT NULLCHAR(10)

If I do an INSERT like the following:

INSERT INTO TTDSLS805501 VALUES (151124 , 'exped9')

The value 'exped9' for the field T$USER is 6 characters long, while the 
definition has got 10. After the insertion, I find that the field for the new record 
is 10 chars long, the last 4 characters being filled with blanks.

But here comes the weird behavior. If I construct the 2 following SELECT on 
this table from SQLPlus, both work OK and return the expected row:

SELECT t$orno FROM TTDSLS805501 WHERE t$user = 'exped9';   
 - 1 row returned
SELECT t$orno FROM TTDSLS805501 WHERE t$user = 'exped9';   
 - 1 row returned

But within a stored procedure and using a local variable the following will 
work OK:

SELECT t$orno INTO eskaria FROM TTDSLS805501 WHERE t$user = my_var;

where my_var is of type VARCHAR2 and has got the value 'exped9'

Whilst the following will come up with the ORA-01403 error:

SELECT t$orno INTO eskaria FROM TTDSLS805501 WHERE t$user = my_var;

where my_var is of type VARCHAR2 and has got the value 'exped9'

Is this normal behavior? why does not the SELECT t$orno FROM TTDSLS805501 
WHERE t$user = 'exped9'; statement return 0 rows in the first place? 

Fermin.

Unless the stored procedure was created with invoker's rights, then it is
probably executing using the permissions and schema of the account that owns
it.  Who is the owner of the stored procedure?  Is it different from who you
are logged into SQL*Plus as?

The explanation might be that, through some reason like synonyms pointing in
different directions from the different accounts, the name TTDSLS805501
might be resolving to different tables altogether...

RE: Weird behavior with VARCHAR fields (was: ORA-01403 error,

2003-09-10 Thread Fermin Bernaus

Yet I do not understand why it returns a row in SQLPlus and it does not in a 
stored procedure... The problem is now fixed, but I'd like to know the reason it won't 
work leaving it as it was. It also fails if I put a string instead of a variable in 
the stored procedure.

Thanks!

Fermin.

Fermin,

You are running into the well documented behavior of the CHAR datatype.  Use
VARCHAR2 instead if you wish to avoid those pitfalls.

Hope this helps...

RE: Multiple Datafiles and performance?

2003-08-14 Thread Fermin Bernaus

In my experience, spreading datafiles across volumes (specially if you are 
careful not to locate the a table's datafiles and its indexes datafiles in the same 
drive) greatly increases performance.

As for the file size, I can not say because I have not tested it, but I think 
it should have no real impact compared to splitting it. Reorganizing the database 
regularly is a better way to optimize performance.

Asunto: Multiple Datafiles and performance?


Oracle 8.1.7.4
Win2k

What is the consensus on datafile sizing and the impact/overhead
multiple datafiles have on performance?

For example, if I have one  2.5g datafile, and three 1g datafiles, and I
need more space,  would it be better to increase the size  of the 1g to
2g or add another 1g datafile?. 
Is it better to keep them all uniform  in size? 

I would think  having multiple datafiles that could be spread across
drive volumes would be beneficial, am I wrong? (Wouldn't be the first
time :)

RE: Change based recovery

2003-08-14 Thread Fermin Bernaus




 Well I am quite de-motivated actually!! but at least 
it is good to know I was (partially) wrong and that I will feel safer after 
reading your comments, thanks!

 I am really in doubt now, but I remember when we were 
testing we did recover all datafiles (the ones that are stated in the v$datafile 
table) from a cold backup exceptcontrolfiles and redolog files; we 
were able to restore the whole database with the commands I wrote down in my 
first message. If I am still wrong, will you please be kind enough to tell me 
which are the exact commands needed to recover the whole database from a cold 
backupif I have no online backups and I lose everything except for the 
archived logs? can it really be done? 

 Thank you so much!

  Fermin,
  
  I dont want to 
  de-motivate you, but I really doubt whether your backup strategy really works. 
  The command that you have mentioned below will NOT do a complete recovery as 
  its a cold backup. 
  
  As for your 
  questions:
  1) You can recover 
  your entire database in either case (Cold or Hot), If you have your archive 
  logs.
   
  Difference being, You have recreate your control file if its a cold DB 
  backup and recover the DB using BACKUP CONTROL FILE 
  option.
  2) Lets look at it 
  the other way; you do NOT need any downtime for Hot 
  backups while you need downtime for Cold backups. Downtime could be very 
  expensive depending on the type of database.
  Secondly, you can 
  take a hot backup very frequently as it does not involve any downtime. Recent 
  backup means less recovery is required and less time to bring up the 
  database.
  
  Let me know if you 
  need anymore info.
  
  Cheers!
  Venu

Lisa,

The 
3rd option (besides shuting down source database and using a controlfile 
trace) is to "alter database backup controlfile to 'filename'; ", use this 
file, then proceed with the recovery as Venu suggests. I've used this 
method on a hot backup to roll the database forward. Also, don't 
bother restoring the redo logs as you will be overwriting / recreating them 
with the "alter database open resetlogs". One more thing I 
noticed. Your until change number looks to me like an archive sequence 
number rather than the SCN it needs to be. Hope this 
helps.

RE: Semaphore problem

2003-08-14 Thread Fermin Bernaus

Did you have a look to the alert file? what does it say? error 13 means some 
kind of permission has been violated at the OS level (at least under UNIX) probably 
trying to access a file (for cration, reading or whatever)

RE: Change based recovery

 a complete restore be done even if we lost ALL control files?
can we recover the entire database from a cold backup provided we have all
archived logs until the failure time?
2 - If the answer is yes, what is the advantage of doing on-line backups
of datafiles and control files?
 
Thanks for your answers, I always learn so much from this list!!

Lisa,
The 3rd option (besides shuting down source database and using a controlfile
trace) is to alter database backup controlfile to 'filename'; , use this
file, then proceed with the recovery as Venu suggests.  I've used this
method on a hot backup to roll the database forward.  Also, don't bother
restoring the redo logs as you will be overwriting / recreating them with
the alter database open resetlogs.  One more thing I noticed.  Your until
change number looks to me like an archive sequence number rather than the
SCN it needs to be.  Hope this helps.

Hi Guys and Gals, 
We are currently doing some testing to enable us to move our production
database from one unix box to another.
We are running a 7.3.4 db in archivelog mode.  The approach that management
want to use is to restore the database on the new server from a backup and
then roll it forward using the archived redo logs.
 
I have a full cold back up from last Friday. I have restored the datafiles,
controlfiles and redo logs onto our test server from the backup tape, and
then ftp'd the archived logs over.
 
I then do -

RE: Multiple Datafiles and performance?

2003-08-10 Thread Fermin Bernaus
 2G.
(Other than time to recover from datafile loss)
It is probably safe to assume that the datafiles  exist on a RAID 5. (for
now)
3) Why the recommendation to take a Win2k datafile to just over 2G?

For future apps I am pushing for optimal recommendations that go  for more
raid 1 sets or raid 10 over the Raid 5. This should allow for more
flexibility for spreading out the i/o.

Thanks for your patience and all the help.

Win2K.  If you decide to increase the filesize, do it to more than 2G
(doesn't have to be by much).  Of course, you didn't mention autoextend so
this may not be an issue.

Also, just how many physical disks do you have?  Logical disks are not the
issue.  If you're going to get any increased performance you should be
putting the second datafile on a second physical disk.  Any how come you're
not using some sort of RAID device (or don't you have your logical drives
striped across your physical drives)?

There is no easy answer to your question without an understanding of the
reality of your disk layout.

 In my experience, spreading datafiles across volumes
(specially if you are careful not to locate the a table's datafiles and its
indexes datafiles in the same drive) greatly increases performance.

 As for the file size, I can not say because I have not tested
it, but I think it should have no real impact compared to splitting it.
Reorganizing the database regularly is a better way to optimize
performance.

What is the consensus on datafile sizing and the impact/overhead
multiple datafiles have on performance?

For example, if I have one  2.5g datafile, and three 1g datafiles, and I
need more space,  would it be better to increase the size  of the 1g to
2g or add another 1g datafile?.
Is it better to keep them all uniform  in size?

I would think  having multiple datafiles that could be spread across
drive volumes would be beneficial, am I wrong? (Wouldn't be the first

Hi there,

I am considering buying an administration tool and programmer's tool. The two 
I know are Toad and BMC's XRAY but since I do not know them very well I have 
difficulties deciding which of them is the best. What I need more is to tune the 
database, trace into time and CPU consuming SQLs, a procedure / trigger editor and 
debugger.

Or maybe you know better tools than these two... any help will be greatly 
appreciated.

RE: Rollback Segs

Yes you are right, sorry but I made a mistake, since we are 
using Baan IVc4 which works against Oracle we have no means to interfere with 
its transactions when they are commited to Oracle and we can not modify them so 
that it uses a specific rollback segment, so the only way for us to do it is to 
disable all except the one we want it to use.

RE: Cannot allocate new log - checkpoint not complete

2003-04-04 Thread Fermin Bernaus Berraondo

Dennis,

This is our actual distribution:

Datafiles belonging to data in a separate disk, name it /baandata
Datafiles belonging to index in a separate disk, name it /baanindex

And 3 redolog files, two of them in another two separate disks, and the third 
one located in the same device as the data files (/baandata).

All of them are mirrored disks.

Your comment makes sense, but if keeping datafiles and one of the redolog 
files in the same device should affect performance, then I wonder why the cannot 
allocate new log, checkpoint not complete message is affecting to the 3 redolog files 
and not only to the one located in that datafile device.

I did not think on this. Anyway I have no more disks in which I can split the 
redologs...

I can not wait for your comments!

Regards,

Fermin.

Basically as the message suggests the redo cannot be
recycled until the checkpoint has completed flushing
out the cache.  

A *workaround* is to add redo log (size or number) but
its really a heads-up about your I/O subsystem not
being up to keep up under stress.

 not have the time to reuse a redolog and has to wait
 until the redolog is ready to be reused. 
 
   So the solution seems to make these redolog files
 bigger or to create new ones. What are the side

There are some other effects I can think of.

Up to you if these are important / significant to your users.

If you make them bigger and you have a standby database then the standby might end up 
being further behind production (unless you have a script to workaround this) and also 
in this case you may then not get the files transferring successfully (depends on your 
network etc).

Also, if you make them bigger and you have a loss of all redo logs (hopefully unlikely 
if they are mirrored on mirrored disks) then you will lose more data as it will be a 
longer period of time since the last archive log was created.

And what about your archive log management scripts - do they keep x days worth of 
files (in which case the volume of archive log on disk will not change) or do they 
keep y files - in this case the volume of disks would increase unless the script(s) 
are altered.

The only potential disadvantage is that recovery will take longer when

I dissagree, they will be bigger but there will be less of them. If
the amount of processed data does not change, I do not think changing the
size of the redolog files should affect the total amount fo bytes to be
backeup up

Thanks for the recommendation anyway ;)

Hi

I would suggest to increase the redo log size. Doesn't effect you during
daily operation, but prevents the database from hanging during nightly
batches. No side effects I can think of (except for the fact that, of
course, it will take you longer to backup the archived logs since the files
are bigger, duh ;).

Good luck

RE: Cannot allocate new log - checkpoint not complete

So do you think the following distribution will contribute to a better 
performance:

data datafiles - device a
index datafiles - device b
redolog1 - device c
redolog2 - device d
redolog3 - device c

instead of:

data datafiles - device a
index datafiles - device b
redolog1 - device c
redolog2 - device d
redolog3 - device a

Because I only have 5 devices available.

Its not really a particular redo log that is the
issue.  You've used up redo's (say) 1, 2, 3 and you
want to cycle around to 1 but the checkpoint that
would free up  redo 1 is not yet finished.

Thus its not a single redo log that is the problem -
the IO rate of the checkpoint is not sufficient quick
to avoid the redo cycling around...If one of your
redo's is on common datafile disk, this could
contribute to this

   This is our actual distribution:

   And 3 redolog files, two of them in another two
 separate disks, and the third one located in the
 same device as the data files (/baandata).
 
   All of them are mirrored disks.
 
   Your comment makes sense, but if keeping datafiles
 and one of the redolog files in the same device
 should affect performance, then I wonder why the
 cannot allocate new log, checkpoint not complete
 message is affecting to the 3 redolog files and not
 only to the one located in that datafile device.
 
   I did not think on this. Anyway I have no more
 disks in which I can split the redologs...
 
   I can not wait for your comments!

 chance do you have your redo

 Basically as the message suggests the redo cannot be
 recycled until the checkpoint has completed flushing
 out the cache.  
 
 A *workaround* is to add redo log (size or number)
 but
 its really a heads-up about your I/O subsystem not
 being up to keep up under stress.

RE: Cannot allocate new log - checkpoint not complete

2003-04-03 Thread Fermin Bernaus Berraondo

I dissagree, they will be bigger but there will be less of them. If the amount 
of processed data does not change, I do not think changing the size of the redolog 
files should affect the total amount fo bytes to be backeup up

Thanks for the recommendation anyway ;)

Hi

I would suggest to increase the redo log size. Doesn't effect you during
daily operation, but prevents the database from hanging during nightly
batches. No side effects I can think of (except for the fact that, of
course, it will take you longer to backup the archived logs since the files
are bigger, duh ;).

Good luck

RE: how to calculate table size

2003-04-01 Thread Fermin Bernaus Berraondo

Hi Ravindra,

Use the following, supposing your db_block_size is 2048 (change as appropiate).

  SELECT segment_type, segment_name,BLOCKS*2048/1024 Kb
FROM   DBA_SEGMENTS
WHERE  OWNER=UPPER('owner') AND SEGMENT_NAME = UPPER('table_name');

You should substract emptied blocks from this table, using:

  ANALYZE TABLE owner.table_name ESTIMATE STATISTICS;

SELECT TABLE_NAME, EMPTY_BLOCKS*2048/1024 Kb
FROM   DBA_TABLES
WHERE  OWNER=UPPER('owner') AND TABLE_NAME = UPPER('table_name');

This will give you how many kb are occupied by empty blocks, so substract this 
amount from the prior result.

Hope this helps.

RE: how to calculate table size

2003-04-01 Thread Fermin Bernaus Berraondo

I've been using this query for both normal and empty tables and works so far.

For those tables with no data in them (or that have suffered no deletion) you 
can ommit the second query since the table should not have any emptied block. Emptied 
blocks are those who have been occupied by data from the table but that have been 
deleted; for these, Oracle marks them as deleted but are still asigned to a table. I 
do not know if you want to consider this free space as part of the table or not.

There is a way to deallocate unused space to a table that has been previously 
used. You must use 'alter table ... deallocate' for that. You have explanations on 
this in the manual, check:


http://download-west.oracle.com/docs/cd/A91202_01/901_doc/server.901/a90125/statements_32.htm#2080417

I am sending this mail to the list as well, I am a learner and do not consider 
myself an expert, maybe someone else can join and comment something.

table that links both of them; you talk about the shadow process, where is it or where 
can I get more info on it.

Thank you for your time.

   The spid column in the v$process column matches the Unix process i.d. You
may need to track it back through the Oracle shadow process.

I usually track our HP-UX 11.0 system with the 'top' command so I
can notice when the system is under slow performance. If that happens, I use
Toad to look for any active Oracle SQL query which may be heavy enough for
degrading the performance.

I think my question is simple, but since I am a newbie on this...
how can I see who is executing an Oracle SQL that is taking all our CPU
provided that I only see his PID with the TOP command? I only see the oracle
process, but I don't know how to get the username and the SQL beside him.

Thank you for your answers!

Fermin.

I just found that v$session.paddr = v$process.addr is the join that has to be 
done. Right?

Dennis, you seem to be have a master in Oracle! please can you help, I can see 
the SPID column under table v$process, but how do I link it to table v$session so that 
I actually know which UNIX process it corresponds to. I think there must be another

Thank you all for your help.

I wonder where I should set TIMED STATISTICS = TRUE, if any of you has the 
time to answer I'd be grateful, but I will look for it in the docs.

RE: Oracle Enterprise vs Standard

2003-03-20 Thread Fermin Bernaus Berraondo

We have BAAN IVc4 and Oracle Enterprise edition at our site. Enterprise 
Edition has got some advantages over the Standard Edition which would be too lenghty 
to explain here, but we are not taking advantage of them and, besides, baan does not 
exploit Oracle's facilities too much and Standard should be enough.

So why do we have Enterprise instead of Standard? because Oracle does not 
provide the Standard edition for our 64-bit HP-UX machine. What a shame :((

I recommend you get the Standard edition, and you can upgrade later on if you 
need.

Regards,

I need to buy a new Oracle license for 50 users. I have got two different
quotes for Oracle Enterprise Server and Oracle Standard; it seems the former
is quite expensive. What problems will I get if I buy the cheaper Standard
version. This Oracle will be used for BAAN ERP implementation. The
environment will be IBM RS6000, AIX 5L and a mixture of LAN and WAN clients

Thanks in advance for you advice
