English preferences for oracle text error

Hi,
i did run the script drdefus.sql script as sysdba
and when i try to install the "Presidential Inaugural Addresses" demonstration application in HTMLDB and i got the following error.
error:------------------------------------------
ORA-20001: This demonstration can only be installed into an Oracle database which has the English preferences loaded for Oracle Text. Please contact your administrator
Can someone help me to fix this error.
Thanks,
Philip.

I have 10.0.1.3.0 in place and used the companion cd of 10.0.1.2.0 to install the necessary tools on a clone. It seems to work and I was able to install the application now. Do I have to apply the patch again for some reason? Looking at the Metalink they say I should? Any experience out there.

Like the error message says, you don't have a global_lexer. So, you need to create a global_lexer and that lexer must have at least a default sub_lexer, then you can use that global_lexer in your index parameters. Please see the demonstration below, including reproduction of the error and solution.

using oracle 10gr2 on windows server 2003
i have tried 1)dropping the index and creating it again, the index type is "CTXSYS"."CTXCAT"
2) deleting the stats -checking
3)recreating the stats- checking
the table here is a materialized view
i need to tell you people that
there are two indexes cat_types_ind and cat_ids_idx on cat_types and cat_ids columns respectively
the inner query uses cat_types_idx index when executed and seen in sqladvisor
1)removing the order by clause will make the query work but i really want that order by clause
2)the inner-query-only works fine
3) i have seen the forums and they have helped regarding the things i tried above but it does not work
please tell me if i need to further elaborate on anything
thanks in advance

Oracle text Error

hi all,
i have the Query like this
select NAME from ORG_NAME
where contains(NAME, 'ward&') > 0;
ERROR at line 1:
ORA-29902: error in executing ODCIIndexStart() routine
ORA-20000: Oracle Text error:
While try to execute the Query i got Error ....
if i'm using any spl char inside the Contains function it Throw the Error
IS any way for using spl char in Contains function?

Thanks a lot Herald ten Dam!! I was really panicking and was straight away asking our production dbas to raise an SR with oracle. Your answer gave me first clue on what could be happening. I could not find what that transaction was and now when I query the database I dont see any distributed transaction. I mean the following query returns 0 rows:
SELECT * FROM DBA_2PC_PENDING;
Also we are not getting any further report/intimation that the Oracle Text errors are happening. So I am guessing it was some distributed transaction that had happened that caused this issue. I wish I could find what that transaction was - is there any way that can be done?
Thanks a lot!

How to install knowledge base file for oracle text

how to install knowledge base file for oracle text?
there are couple of files droldUS.dat,.. which are required to generate gists and themes, where can i find them or install them.
please help!

I checked the download page and it says:
"All Release 2 download pages contain Oracle Companion, Client, Clusterware, Gateways, and Application Express standalone downloads"
so you should already have it. Try searching for the filename that was in your error message.

[Microsoft][ODBC driver for Oracle]Syntax error or access violation

Hi,
When I am trying to connect to Oracle 8.1.6 database using Microsoft ODBC driver for Oracle. The connection is established.
But while creating CallableStatement, I am getting error "[Microsoft][ODBC driver for Oracle]Syntax error or access violation".
What I need to do to resolve this problem.
Raj

Hi Satish
It could be an issue with the driver.
You can try with the OLEDB n Oracle native connection to test if the issue persists.
Also you can refer to the [Troubleshooting Database Connectivity for Crystal Reports|http://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/d05b3bb7-0f28-2c10-4ea3-84dbdc4e414e&overridelayout=true]

Pre-built Thesaurus for Oracle Text

Could anyone provide me direction on where to get Pre-built Thesaurus For Oracle Text that is specific to pharmaceutical science companies.
any advice would be appreicated

There are two ways you can use pre-built Thesaurus in Oracle.
1) Just as an earlier reply you got, use the Thesaurus Management System (TMS) product that comes with a prebuilt Medra database for mdeical and other related text mining.
2) Import and supplement your own medical thesaurus into the existing thesaurus that comes pre-loaded with the database using the provided APIs. As an example, you could download from the web the UMLS thesaurus content, convert the data into the API required format and load the UMLS data into the database. You can then cluster and classify documents/abstracts based on themes or subject matter.

Is possible to alter default collations for Oracle Text?

Oracle supports custom linguistic sorts for sorting and matching.
Is something similar availble for Oracle text?
Specifiaccaly we want to alter base letter definitions and ignorable characters for a given language.

Barbara, thank you for your reply.
The purpose was to satisfy certain requirements of arabic text search. These seem to be fulfilled by WORLD LEXER, so the case is closed.
Note that BASIC and AUTO LEXER implement differently the lexing of arabic text, with result not to be candidates for such a solution.
By the way, I tried to use skipjoins for setting an ignorable character but it did not work (auto lexer).

MultiLanguage support for Oracle Text

Hi,
We are providing multi language support in our application. So, we are using the NVarchar datatype. And we want to provide the search option for that text. So if i tried to create an index on that column it is giving the error and unable to create the index on that column. Same if tried to create an index on Char and Varchar datatypes it was successfully created the index on those columns and search is working fine.
But according to our requirements, we should provide the multi language support in our application.
Please suggest me how to create indexes on NVarchar datatype and providing the oracle text search features on that datatype.
Waiting for your favourble reply.
Thanks in advance.
Regards,
Anil.

No place in the standard docs very well. There was a note I found on it at one point, but I can't find the number at the moment. 10g new features for Text note has some info on it though. I'll look again tomorrow.
I did a lot of research on the world_lexer a few months back (wrote some info on IR & Oracle Text our newest Oracle Press book), and got some good info from the product team. One of the chapters covering Text will be made available for free and there is a diagram in there of how the world_lexer processes text. I'll post the link to the forum when it is available.
Since it doesn't require a language column, it attempts to auto-recognize the text...but not really the language. More like...the type of text it is. White-space delimited languages like English or Spanish are easy to break into tokens. Japanese & Korean are another story...no white-space delimiter. Arabic is yet another story. Those are essentially the buckets that text is thrown into for breaking into tokens when using the world_lexer.
So, where does German fall? It will be broken up similar to English. But what about the special features (like alternate spelling) that are available? Nope - sorry. It doesn't know German from French. With the multi_lexer you defined sub-lexers and told Text which records were German or French. This means that you can use more of the lang features with it. The world_lexer is much easier to implement and maintain, but it is a trade-off.
Hope that defines it a little better.

About index memory parameter for Oracle text indexes

Hi Experts,
I am on Oracle 11.2.0.3 on Linux and have implemented Oracle Text. I am not an expert in this subject and need help about one issue. I created Oracle Text indexes with default setting. However in an oracle white paper I read that the default setting may not be right. Here is the excerpt from the white paper by Roger Ford:
URL:http://www.oracle.com/technetwork/database/enterprise-edition/index-maintenance-089308.html
"(Part of this white paper below....)
Index Memory                                  As mentioned above, cached $I entries are flushed to disk each time the indexing memory is exhausted. The default index memory at installation is a mere 12MB, which is very low. Users can specify up to 50MB at index creation time, but this is still pretty low.
This would be done by a CREATE INDEX statement something like:
CREATE INDEX myindex ON mytable(mycol) INDEXTYPE IS ctxsys.context PARAMETERS ('index memory 50M');
Allow index memory settings above 50MB, the CTXSYS user must first increase the value of the MAX_INDEX_MEMORY parameter, like this:
begin ctx_adm.set_parameter('max_index_memory', '500M'); end;
The setting for index memory should never be so high as to cause paging, as this will have a serious effect on indexing speed. On smaller dedicated systems, it is sometimes advantageous to temporarily decrease the amount of memory consumed by the Oracle SGA (for example by decreasing DB_CACHE_SIZE and/or SHARED_POOL_SIZE) during the index creation process. Once the index has been created, the SGA size can be increased again to improve query performance."
(End here from the white paper excerpt)
My question is:
1) To apply this procedure (ctx_adm.set_parameter) required me to login as CTXSYS user. Is that right? or can it be avoided and be done from the application schema? This user CTXSYS is locked by default and I had to unlock it. Is that ok to do in production?
2) What is the value that I should use for the max_index_memory should it be 500 mb - my SGA is 2 GB in Dev/ QA and 3GB in production. Also in the index creation what is the value I should set for index memory parameter - I had left that at default but how should I change now? Should it be 50MB as shown in example above?
3) The white paper also refer to rebuilding an index at some interval like once in a month:   ALTER INDEX DR$index_name$X REBUILD ONLINE;
--Is this correct advice? i would like to ask the experts once before doing that. We are on Oracle 11g and the white paper was written in 2003.
Basically while I read the paper, I am still not very clear on several aspects and need help to understand this.
Thanks,
OrauserN

Perhaps it's time I updated that paper
1. To change max_index_memory you must be a DBA user OR ctxsys. As you say, the ctxsys account is locked by default. It's usually easiest to log in as a DBA and run something like
exec ctxsys.ctx_adm.set_parameter('MAX_INDEX_MEMORY', '10G')
2. Index memory is allocated from PGA memory, not SGA memory. So the size of SGA is not relevant. If you use too high a setting your index build may fail with an error saying you have exceeded PGA_AGGREGATE_LIMIT. Of course, you can increase that parameter if necessary. Also be aware that when indexing in parallel, each parallel process will allocated up to the index memory setting.
What should it be set to? It's really a "safety" setting to prevent users grabbing too much machine memory when creating indexes. If you don't have ad-hoc users, then just set it as high as you need. In 10.1 it was limited to just under 500M, in 10.2 you can set it to any value.
The actual amount of memory used is not governed by this parameter, but by the MEMORY setting in the parameters clause of the CREATE INDEX statement. eg:
create index fooindex on foo(bar) indextype is ctxsys.context parameters ('memory 1G')
What's a good number to use for memory? Somewhere in the region of 100M to 200M is usually good.
3. No - that's out of date. To optimize your index use CTX_DDL.OPTIMIZE_INDEX. You can do that in FULL mode daily or weekly, and REBUILD mode perhaps once a month.

CS5 - Text format for classic text error

will now have to re-edit every part.
Clearly you can get around this by other formats but fact is if you have a document that has negative spacing dont open it in CS5 cause you
This may have been in recent update.
Flash now resets them when you open the file to 0, if you notice or not.
when you have negative (-20) set in spacing, usually used when you have margins.
Classic Text Error
Flash CS5

Here's a workaround.
FixTextIndent is a class with static methods that
provides a workaround for the Flash CS5 text formatting
bug. The Flash CS5 IDE will not remember the text
indent setting for either static or dynamic text fields.
We can set the indent in Actionscript for dynamic fields,
so to use this class, convert your fields to dynamic,
then set the left margin.
When you call FixTextIndent methods, they will set
the indent to the negative of the left margin.
