Re: interMedia Text
As you are running 8.1.7 you should not need the extproc_connection_data entry. What you need is that the LD_LIBRARY_PATH includes $ORACLE_HOME/ctx/lib in the environment *before* you start the Listener. The listener.ora entries are the regular entries for the database SIDs.

RE: Intermedia Performance Benchmarks anyone ?
Jack, Thanks for your time on this. Most revealing and useful for what I have ahead of me Kind regards from the UK. Martin -Original Message- Sent: 04 October 2001 22:47 To: Multiple recipients of list ORACLE-L Martin, We use interMedia Text to index and query up to about 10-15 million CLOB documents (up to 5KB each). We're on 8.1.6.0.0 under Win2k - 2 550MHz CPUs, 2GB RAM, 18 36GB drives. Because a domain index cannot be partitioned, we have the documents spread across 5 tables (on 6 drives). One is a 2 partition table (each partition on its own drive) containing the current two months of docs, the other 4 hold the 4 prior months' docs. We can query the entire 6 months of docs via a Union View on them - even Contains() queries work fine on this view. When we add a new month's partition, the prior month's partition gets turned into a table (segment exchange). The interMedia Text indexes on the partitioned table and the new prior month are rebuilt. Lately we've been getting about 3.5 million docs/month and the index rebuild takes about 7 hours - that's 7 hrs. for the index on the prior month and 7 more hours for the index on the partitioned table, which only contains one month of docs at that point. Since we're adding docs every day, we sync the interMedia index every morning. Last night we added about 200,000 docs and it took about 3 hours for the index to resync. We don't use ctxsrv, but use CTX_DDL.Sync_Index. When we get over about 4.5 million docs in a table, the resync really slows down. The in-memory part still happens at about 150 docs/sec, but when interMedia writes to disk it slows down a bunch. What took 3 hours today will take 10 hours in a couple of weeks. That's why I plan on spreading the DR$$I segment across multiple drives by spreading the datafiles of its tablespace across those drives. BTW, that brings up some performance points - be sure you cache the DR$$R segment (use CACHE not CACHE READS, due to bugs in Oracle): Alter Table DR$YourIndexName$R Modify LOB (Data) (Cache) ; Also ensure that your LOBs are out-of-line and stored in their own segment(s) on drive(s) separate from the regular data. Make sure that your I_TABLE_CLAUSE, R_TABLE_CLAUSE, and I_INDEX_CLAUSE all specify tablespaces on their own drives to spread the I/O out even further. We're getting 2GB more RAM on a new server, so I plan on caching the 900MB DR$$X segment, which is the index on the DR$$I token table. I've learned a lot about how interMedia Text processes different kinds of queries by watching disk I/O on Win2k's Performance Monitor while I issue various flavors. Our folks use lots of complex query terms with heavy use of the Stemmer. I've gotten them to switch from using tons of ORs to using the Equivalence operator and we're getting much better results using NEAR than simple ANDs. Performance is very good, with CONTAINS queries returning results in less than a second for terms that are rare in the docs, up to a minute for terms that are common in lots (e.g. hundreds of thousands) of docs. If you're going to do synonym searches, you'd better start looking for a good thesaurus - the one Oracle ships is pretty limited. We've not found a good one for the technical lingo our docs contain, so we don't do ABOUT queries at this time. Get familiar with CTX_Query.Explain, it will help you understand things like what the Stemmer *really* does and how complex queries are parsed. Hope this helps. Jack Jack C.

RE: Intermedia Performance Benchmarks anyone ?
Title: RE: Intermedia Performance Benchmarks anyone ? Hi Martin, I've had to implement intermedia in the past. with 1 million records intermedia will do the job in an acceptable amount of time. However, when testing it I found that the more advanced features I used (fuzzy, etc.) the worse performance became. It works well if you are doing a straightforward search. I also found there were problems with creating the library on HP/UX (part of the install). I had to create it manually. There are also tricks for indexing more than one column in one index. The documentation says you can't, but it can be done. I know there are people on the list that have done this. I didn't run any formal benchmarks. We had indexed ~6million records on long fields (like description) and performance was directly related to how selective the keywords were. Indexing time - If I remember right, creating one index on one of these description columns ran in ~2 hours. I also batched my updates. (I didn't run ctxsrv) The index ended up being ~1.5GB. Hope this helps and let me know if you have any other questions, I'll try and answer them.

The in-memory part still happens at about 150 docs/sec, but when interMedia writes to disk it slows down a bunch. What took 3 hours today will take 10 hours in a couple of weeks. That's why I plan on spreading the DR$$I segment across multiple drives by spreading the datafiles of its tablespace across those drives. BTW, that brings up some performance points - be sure you cache the DR$$R segment (use CACHE not CACHE READS, due to bugs in Oracle): Alter Table DR$YourIndexName$R Modify LOB (Data) (Cache) ; Also ensure that your LOBs are out-of-line and stored in their own segment(s) on drive(s) separate from the regular data. Make sure that your I_TABLE_CLAUSE, R_TABLE_CLAUSE, and I_INDEX_CLAUSE all specify tablespaces on their own drives to spread the I/O out even further. We're getting 2GB more RAM on a new server, so I plan on caching the 900MB DR$$X segment, which is the index on the DR$$I token table. I've learned a lot about how interMedia Text processes different kinds of queries by watching disk I/O on Win2k's Performance Monitor while I issue various flavors. Our folks use lots of complex query terms with heavy use of the Stemmer. I've gotten them to switch from using tons of ORs to using the Equivalence operator and we're getting much better results using NEAR than simple ANDs. Performance is very good, with CONTAINS queries returning results in less than a second for terms that are rare in the docs, up to a minute for terms that are common in lots (e.g. hundreds of thousands) of docs. If you're going to do synonym searches, you'd better start looking for a good thesaurus - the one Oracle ships is pretty limited. We've not found a good one for the technical lingo our docs contain, so we don't do ABOUT queries at this time.

RE: Intermedia Performance Benchmarks anyone ?
Ross, I disagree that interMedia Text is way too slow to scale. Our experience has convinced us that I/O bottlenecks are the main performance killers with large interMedia Text indexes. The problem is that it takes some experience to find out how this special kind of index is structured (6 or 8 separate table and index segments per index) and how it behaves. As usual, the Oracle docs are pitifully inadequate - you've gotta search through TechNet and MetaLink for details and bug workarounds (like CACHE instead of CACHE READS for DR$$R). Caching the DR$$R segment helped immensely and I can see that when pieces of the DR$$X index are cached, queries with terms in those pieces are lightening fast. I am betting that when I spread the DR$$I table across multiple drives, instead of the single drive ours is currently on, we'll see much better performance of NEAR queries (which depend on the word position info. there), as well as faster index resyncs. In 9i Domain Indexes become partitionable, so I'm looking forward (in about a year - experiences with 6.0, 7.0, 8.0 and 8.1.5 have made me wary) to putting our 6 (or more) months of docs into one partitoned table. There may be other I/O distributing kinds of enhancements by then, as well. For sure I'll have explored every trick I can think of! ;-) With more drives and a bit more RAM, I think we can handle 10 million docs per month (60 million total online), even on our lil' ol' Win2k box. That's just x3 to x4 of what we do now. Jack Jack C. Applewhite Database Administrator/Developer OCP Oracle8 DBA iNetProfit, Inc.

RE: Intermedia Performance Benchmarks anyone ?
I looked into SSD, they are like $15-17k / gb. Very expensive. And with Oracle buffering, I would expect the performance wouldn't be huge.

Title: RE: Intermedia Questions, Any Gurus on This Subject?
Hi Vicky,
You need to create a preference to define the storage clause with CTX_DDL. I did this at a former employer and I don't have the scripts handy, sorry to say. The documentation does go over this in detail. You can specify just about everything for storage of your imt index in the preference. You can even put the separate pieces of the index in separate ts's. Buffer pool though, I'm not sure. See below a cutout from the doco.
Specifying Storage Attributes
The following examples specify that the index tables are to be created in the foo tablespace with an initial extent of 1K:
begin
ctx_ddl.create_preference('mystore', 'BASIC_STORAGE');
ctx_ddl.set_attribute('mystore', 'I_TABLE_CLAUSE',
'tablespace foo storage (initial 1K)');
ctx_ddl.set_attribute('mystore', 'K_TABLE_CLAUSE',
'tablespace foo storage (initial 1K)');
ctx_ddl.set_attribute('mystore', 'R_TABLE_CLAUSE',
'tablespace foo storage (initial 1K)');
ctx_ddl.set_attribute('mystore', 'N_TABLE_CLAUSE',
'tablespace foo storage (initial 1K)');
ctx_ddl.set_attribute('mystore', 'I_INDEX_CLAUSE',
'tablespace foo storage (initial 1K)');
end;

ctx_ddl.set_attribute('storage_small','P_TABLE_CLAUSE','tablespace
LOBADM_01_SMALL_DATA');
end;
/
Then create index like:
create index lobadm.client_full_nm_indx on lobadm.client(full_nm)
indextype is ctxsys.context
parameters('storage lobadm.storage_small')
/
Hope this helps

RE: Intermedia
Title: RE: Intermedia Hi Gary, This is what happened. A regular install would not succeed with the CREATE INDEX statement. I put a call in to support. Lucky for me I got a knowledgeable woman on the phone who knew exactly what the problem was. The libraries could not be created when $ORACLE_HOME was referenced in the install scripts. I had to hard-code the library name with the value for $ORACLE_HOME. Now that I look through my script, that was the only thing that got hosed. After I made that change everything was fine. Hope this helps someone...

RE: Intermedia text table design
Ranganath, You've defaulted to in-line storage of CLOBs. You could specify "Disable Storage In Row" and point the CLOBs to different tablespaces, thus spreading your I/O out over more drives. You can also define a custom Basic_Storage interMedia parameter, by which you spread out the 5 or 6 segment types of an interMedia index on different tablespaces. See Chapter 7 in "Oracle8i Application Developer's Guide - Large Objects (LOBs)" for details on LOB storage and the "Oracle8i interMedia Text Reference" for details on indexing parameters.

Re: Intermedia Domain index and tablespace
take a look at the "Specifying
Storage Attributes" section of
http://technet.oracle.com/doc/inter.815/a67843/cddlpkg.htm#16740
there is an example for creating a storage preference for the
index and assigning different components of the domain index to different
tablespaces.
after u have set the preferences up u'll have to create the
index with something like:
===create indexAAA on BBB.CCC(DDD)
indextype is ctxsys.context
parameters ('filter ctxsys.EEE
storage FFF');

Subject: Intermedia Domain index and

Dear list !
I'm creating an Intermedia
domain index , and i want to build the index ( and related DR$... tables and
indexes) ina specific tablespace , say IM_TBS .
Although i can not specify the
TABLESPACE attribute directly , when building a domain index , right
?
So , how can i do it
?
This is the create index
statement i use
CREATE INDEXmytab_idx1 ONmytab(
bcontent )
INDEXTYPE IS ctxsys.context;Thanks a lot in advance
.
RE: Intermedia Domain index and tablespace
You need
to create preferences and specify them in your create index statement.
This is all in the documentation, by the way. Also, this does not affect
your IOT storage parms. You will have to modify those separately or you
will blow maxextents as your index grows.
Here's
what mine look like
exec
ctxsys.ctx_ddl.create_preference('product_storage','BASIC_STORAGE');
exec
ctxsys.ctx_ddl.set_attribute('product_storage','I_TABLE_CLAUSE','tablespace
ctx_idx_a storage (initial 100m next 100m)');
exec
ctxsys.ctx_ddl.set_attribute('product_storage','K_TABLE_CLAUSE','tablespace
ctx_idx_a storage (initial 100m next 100m)');
. etc
.
And
here's how I use it
create indexx onq.table(search_string)
indextype is
ctxsys.context
parameters (
'lexer product_pref
storage
product_storage
datastore
product_datastore'
)

RE: Intermedia Domain index and tablespace
Andrey,
You're
right in that you cannot explicitly name the tablespace(s) in the Create Index
statement. However, you can put the various (5 or 6 segments in all)
pieces of an InterMedia Text index in different tablespaces by creating a
Basic_Storage parameter, with suitable attributes. Your statement below
would then have an additional clause such as:
Parameters ('Datastore CtxSys.My_Direct_Datastore
Storage CtxSys.My_Basic_Storage Memory 5000') ;
That
directs InterMedia to create the index according to the Attributes you define in
My_Direct_Datastore and My_Basic_Storage. The Memory 5000 part tells
InterMedia to use about 50MB of RAM to do the sorting, etc. required to build
the index. Make this as big as you can, since it is the key to fast index
creation - that is, if the table is large and already
exists.
See
the chapter on Indexing (chapter 3 for Oracle 8.1.6) in the "Oracle8i interMedia
Text Reference" for all the details.
Hope
this helps you.
