Hi,

We have a procedure where we insert records into a partition of a table on which local context indexes have been built.

Then we call the ctx_ddl.sync_index procedure to sync the inserted records.

The sync_index_procedure accepts memory as an input argument.

From what I have seen, the higher the memory that I give, the quicker the sync takes place.

For e.g. if I give 500M, a sync of a partition containing 8 million records takes about 2 hours. If I give 250M, then the sync takes about 4 hours.

How do I determine what is the optimum memory argument that needs to be supplied to thsi procedure.






Thanks,
Vijay

Set it as high as you can without causing paging. Please see the section of the online documentation below for details.
