Hello everyone,
We have recently migrated our SAN from Emc san ( FC with 4gbe) to dell san (Iscsi with 1gbe) ..2 ports on the the dell san have been teamed up as one ...Also we migrated our Sap app & ibm db2 9.1 db from ibm p5 to p7 server ...Since then Many short dumps have appeared with the msg "time_out" & the no. of swaps for program buffer went upto 60,000 /day . Although the hit ratio was still 99%...then I increased the buffer size after which the swaps were reduced to 10,000/day but the time_out still occurs specailly for some Z transactions & the overall performance has degraded as well......Any suggestions or help would be aappreciated.
Thanks & regards,
Kartik Singh Sodhi
