Grouper Users - Open Discussion List

["Bryan E. Wooten" <>]

Thanks,

 

I am currently rebuilding my LDAP indexes. It seems my LDAP server ran out of disk space and so the indexes were never built L

Also, the first thing to do with Grouper slowness is to analyze your database tables…

 

This has an example for Oracle, though other databases are similar

 

https://spaces.internet2.edu/display/Grouper/Upgrade+notes+from+Grouper+v1.6+to+v1.7

 

Generate script:

select 'ANALYZE TABLE ' || table_name || ' COMPUTE STATISTICS;' as script from user_Tables where table_name like 'GROUPER%'

ANALYZE TABLE GROUPER_ATTRIBUTES COMPUTE STATISTICS;            
ANALYZE TABLE GROUPER_ATTRIBUTE_ASSIGN COMPUTE STATISTICS;      
ANALYZE TABLE GROUPER_ATTRIBUTE_ASSIGN_VALUE COMPUTE STATISTICS;
…

 

Then run that script

 

Thanks,

Chris

Hi Bryan,

 

The first place I'd start is looking at my subject source configuration and the LDAP server and ensure that: the queries that grouper is performing are searching against indexed attributes, the indexes are fully built-out, and they are being used in the search.  If not, tweak each end (subject config & ldap) until those are snappy.

So I have refreshed by LDAP subject source server and my test data base had also been refreshed.

 

At this point I obliterated my stem containing all the course enrollment loader groups.

 

I then restarted Grouper. The Grouper loader job (SQL_GROUP_LIST) has now be running for over 18 hours and has still not completed, it is continuing to add course groups but is not anywhere near completion.

 

How do I go about diagnosing this slowness?

 

Thanks,

 

Bryan
