RE:

Hi

I'd use a larger amount of db_blocks_buffers. You are using 7168*4k = 28MB to blocks buffers.

In our test environment, whe have db_block_buffers = 25600 # 25600 * 8 Kb = 200 Mb.
Look at he hit ratio to tune this parameters.

Also I'd increase the log_buffer parameter (buffer for uncommitted transactions in memory). Check if it's enough looking at the 'redo log space request' (it must be near to 0). It indicates the times an user process waited for space in the redo log buffer.

And, of course, I'd re-tune this parameters when the DB and aplications were runing.

I cant say anything more because I dont know the aplication wich is going to run on the instance. (and because Im not a DBA, Im a developer).

Correct if Im wrong.

HTH Carlos.
