After upgrading the siebel application from 7.7 to 8.0, the contacts view loads very slowly.When the SQL is ran directly against the DB2 database, it takes 2 seconds. Looking closely at the SQL, the application is actually adding a clause at the end of the SQL: FOR FETCH ONLY OPTIMIZE FOR 1 ROW. When we ran the SQL along with this clause on the DB2 database, it takes 18-20 seconds. Why would this clause make so much difference? Is there any setting on the database that should be changed?
So, there are two issues with the SQL:
1. If X_LAST_NAME_CI column in the where clause of the SQL, with FOR FETCH ONLY OPTIMIZE FOR 1 ROW clause is used, it is taking a lot of time. Without this clause, it takes less time.
2. If we replace the X_LAST_NAME_CI with CON_LAST_NAME column, result is very quick with either FOR FETCH..... clause or not.
