Its possible that someone might have started the Informatica services from the command prompt. In that case you would not find the inafservice.exe in the task manager, but there would be one java process which will be running. Without node process, pmrepagent and pmserver will not run. You can follow below steps to stop the services from command prompt.
- Login to the server with the user who starts Informatica services.
- Go to $INFA_HOME/tomcat/bin directory.
- Run infaserivce.bat stop
After few min you can verify whether the repository process and integration service process are still running. In that case, you can share the catalina.out log and node.log from $INFA_HOME/logs/<node_name> directory.
Thanks Smitha for the details.
There was a Windows Task Scheduler that used to execute at system startup. Disabled that job and shutdown infaservice resolved the issue.
