Memory/Resources Errors On System That Has Abundent Resources Running Oracle Linux 6
(Doc ID 1578925.1)
Last updated on OCTOBER 03, 2019
Applies to:Oracle Applications DBA - Version 12.1.3 to 12.1.3 [Release 12.1]
Adpatch recommends the use of a high number of workers, ie 128. The machine is a blade server running 4 processors each with 8 cores and 2 threads per core. The machine has 128 Gb of RAM.
Now trying to apply a patch and when running XDOLoader.class the system is erroring out indicating that it does not have enough resources.
Reducing the number of workers to 8 fixed the issue, but clearly something is wrong since the machine should run 128 workers without problems
Checking a pid error log file from an adworker.log ie /oraapp/r12/oadev1/apps/apps_st/appl/admin/OADEV1/out/hs_err_pid14786.log shows the following
rlimit: STACK 8192k, CORE 0k, NPROC 1024, NOFILE 65535, AS infinity
* hard nofile 65535
* soft nofile 4096
* hard nproc 16384
* soft nproc 2047
Migration to RHEL6/OEL6
