Perhaps you should consider disabling / dropping the index during the first procedure and then recreating it. You can use commands like 'execute immediate' within a procedure to issue DDL.

Otherwise perhaps you can change the inserts to some kind of bulk insert - depending on how your application behaves.

If it's any compensation I've seen many situations where the application does things like creating temporary indexes, analyzing tables, etc during a procedure to get performance right. A classic example was one procedure which truncated a table, inserted a pile of rows and then did some complex queries - we had to analyze the table after the inserts and before the selects so that the optimiser could use the correct indexes, etc - made a huge difference.

Regards,

     Mark.

I have a table in my application . This table gets all inserts during one procedure and select during other . Now if I make an index on this then the first procedure gets slow and if i drop the index then the second procedure gets very slow.
Is there some solution to get out of this problem
