Re: ctx_ddl.sync_index question

Surelly 12M seems to be pretty low...

check out:
http://www.oracle.com/technology/products/text/htdocs/Index_Maintenance.html

Also maybe you have big redo logs alreasy but I suggest to check and increase if needed... because sync gives you lots of usage.

Also remember that no other operations(ALTER INDEX... or optimize_index) on text index when sync or optimizing is running.... or you might get negative effect.

'12M' seems to be quite low. That is the memory allocation for the index synchronization.
Values of 50M and 100M and higher wouldn't be unreasonable.

Ensure that you have a job to sync the index frequently.

Monitor the count of pending updates by doing a count on CTX_USER_PENDING;
