AIX CPU usage
hi,
We have two LPARs, both have same capacity and believe same configuration. ulimit settings for oracle user is unlimited for both LPARs. Installed oracle databases with same configurations on both LPARs, both databases sync every second so volume is same. Both LPARs/databases have identical jobs running at exact time.
We run net-backup process at same time on both LPARs every night. LPAR1 finishes in 30 min but LPAR2 takes 2 hours to complete.
When I observed, i noticed backup processes running on LPAR1 consuming 35 to 40% CPU for every PID. And i noticed backup processes running on LPAR2 consuming only 5 to 10% CPU for every PID.
I'm understanding that backup process in LPAR2 delays because it's not utilizing available CPU, please correct me if 'm wrong? Secondly how we can make or instruct the AIX to utilize more CPUs for the backup processes running on LPAR2?
-Thanks in advance

If somebody knows there are some tools can show how many CPU, memory useage on AIX and can automatically send email?
Such as when setup if CPU is used over 80%, send alert by email automatically.
Maybe BMC has this tool? (6 Replies)
