Avnish - Since nobody has mentioned it yet (my posts arrive late, so probably will by the time this appears), get Cary Millsap's book Optimizing Oracle Performance

[EMAIL PROTECTED] -----Original Message----- [mailto:[EMAIL PROTECTED] Sent: Thursday, December 11, 2003 12:35 PM To: Multiple recipients of list ORACLE-L Hello Everyone, I am trying to get some help/suggestions reg. how to troubleshoot performance issues. Little back ground about our environment. Its third party application (Logician) from GE. There are total 11 databases, all on oracle 8174 H-UX 11i in cluster environment. All the databases are on EMC Symmetrix using 6 disks. All the clients are connecting to database thru Citrix terminal servers. In last one year we spend lots of time/money in tuning databases, replacing Citrix servers but end result is same. I was wondering if anybody out there has ran into same kind of situation. Our (DBAs) guess is the disk layout is not optimal but we also dont have any data to prove that disks are the bottleneck. Is there any way to collect these kinds of stats in Oracle. We aren't getting much help from our SAN administrator.
