OPMN failed to start a managed process OHS
We had a issue after a power failure in one of the server where the OHS use to fail to start and keep on throwing “failed to start a managed process after the maximum retry limit” all the time even after rebooting the OS.
The error looked like below:
[bin]# ./opmnctl startall opmnctl startall: starting opmn and all managed processes... ================================================================================ opmn id=newart.techpaste.com:6701 Response: 0 of 1 processes started. ias-instance id=instance1 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ -------------------------------------------------------------------------------- ias-component/process-type/process-set: webcache1/WebCache-admin/WebCache-admin/ Error --> Process (index=1,uid=1508762676,pid=3781) failed to start a managed process after the maximum retry limit Log: /home/oracle/Middleware/Oracle_WT1/instances/instance1/diagnostics/logs/WebCache/webcache1/console~WebCache-admin~1.log
And in webcache admin logs we use to see below error:
-------- 14/10/24 02:11:49 Start process -------- Web Cache admin server is already running as process 5.
If you are getting similar error like above please follow below steps to resolve the same.
cd to webcache location here we had webcache in /home/oracle/Middleware/Oracle_WT1/instances/instance1/config/WebCache/webcache1 folder.
Search for webcacheadmin.pid file and remove/rename the file to something else and try to restart the OHS services it shall work fine.
