The query does not call any UDFs and does not reference any proxy tables.
However, a few things to note...
ASE servers are running under Solaris 10 on Sun/HP platforms. We have a total of 16 ASE PROD servers. Each ASE server has 5-7 client databases (one database per client). The ASE servers are typically configured with 10G of memory each. The data cache of ~6Gb is shared among all client databases. This data cache has ~1Gb of 16K, 128Mb of 4K and the rest is 2K pool.
All the ASE PROD servers are connected to SAN. Although, ASE devices are scattered across 10 SAN volume groups, there is a good possibility of disk contention.
I was suspecting disk I/O contention and cache contention in that order.
What tools/queries on mon tables would you suggest to confirm/eliminate my suspicions?
Thanks.
