Step1: Find the process that are consuming high CPU on DB Node.
oracledb=>prstat
PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
26477 oracledb 2407M 2369M cpu2 0 0 2:59:40 13% oracle/39
1958 oracledb 2393M 2355M cpu6 0 0 1:54:27 12% oracle/1
2124 oracledb 2393M 2355M cpu2 0 0 1:53:35 12% oracle/1
2202 oracledb 2393M 2355M cpu5 0 0 1:52:07 12% oracle/1
Step2: Identify the PROCESS(Apps Node) from DB.
SQL>select s.sid, s.serial#, s.process, s.program, s.module
from v$session s, v$process p
where s.paddr =p.addr and p.spid in ('26477','2124','1958','2202');
SID SERIAL# PROCESS PROGRAM MODULE
---------- ---------- ------------ ------------------------------------------------ --------------------
93 35457 17991
Step3:On the APPLICATION Server, grep for the PROCESS:
apps=>ps -ef|grep 17991
apps 27982 25127 0 14:14:24 pts/2 0:00 grep 17991
apps 17991 9806 0 10:40:02 ? 0:02 ar60run P_CONC_REQUEST_ID=13318110 P_CORP='055' P_COMPANY='004' P_AS_OF_DATE='1
Step4:Get the Concurrent Request details
