Who's using other 50%? Is SP active or is waiting? On 10/23/2003 02:19:32 PM, [EMAIL PROTECTED] wrote:
Allan,
I don't know about the source machine. I receive around 350Megs of data every day.
I'm using sp_ctrl to stop and restart my Post process and monitor the queue.
I'm pretty sure that the bottleneck come from Shareplex. Oracle is
waiting
for Shareplex, we have server's resources available (CPU is 50% idle).
How can we speed up Shareplex?

How big is the box that is the source for this machine? Have you tried running sp_ctrl and doing a shutdown and startup?

Hi gurus,
Oracle 8.1.7.3 on Sun Solaris
One of our databases has been updated by Shareplex, and we have a huge
performance problem....
Shareplex is the only process running on this database. Here is the output of v$session_event
SID EVENT TOTAL_WAITS TOTAL_TIMEOUTS TIME_WAITED AVERAGE_WAIT -- ------- ----------- -------------- ----------- ------------ 17 latch free 83 69 1 ,012048193 17 log file sync 15 0 9 ,6 17 db file sequential read 52 0 6 ,115384615 17 file open 1 0 0 0 17 SQL*Net message to client 74791 0 27 ,000361006 17 SQL*Net message from client 74791 0 5235 ,069995053
I really don't see any Oracle performance problems.....
My problem is the backlog (queue) of Shareplex is getting bigger and bigger. Where is the bottleneck?
The only thing I can see is the server. The server is a Ultra-80, 2
CPU
450Mhz, 2048Megs of RAM According to "top", this process is taking 50%
of the CPU. and my "load average" is 1.26, 1.27, 1.24
My average load exceed 1, can I conclude that the CPU is the bottleneck?
What are my possibilities?
TIA Luc
