See if you can do it using a stored procedure or using a stored procedure defined inside a trigger on a dummy a tables that you can update from your tool.

Hi All,

Thanks for all your responses.
I do know that we can use 'alter system' or 'alter session' to change db_file_multiblock_read_count parameter. As I mentioned in my original email, I can not use any DDL type statements in
ETL tool.

I am looking for a technique or undocumented hint (if any) that we can use in
SQL statement to increase the value of db_file_multiblock_read_count.

Thanks in advance for all your suggestions.

Regards,
Prasad

Prasada,

It is a dynamic parameter that can be modified using an "alter system" or an "alter session" as the case may be.

Cheers,

Gaja.
