well, have you traced the statement yet? That's where to start, with autotrace.

My count(*) which executes a FTS (in a load to mitigate any ORA-1555 error) takes 15 minutes to count 50 million rows.

Hi list,

I issue a select count(*) from mytable and last 30 seconds.

The table has 1,466,196 records and were loaded with a batch process, so they are in a countinous space.

I consider that time exagerated.

The TBS is LMT with a Uniform size of 128 MB.

The block size is 8MB, version 9.2.0.1.0 in Windows 2000.

Where should I start looking ???
