During the startup of the tomcat I received following error messages:
JVMSHRC020E An error has occurred while opening semaphore
JVMSHRC336E Port layer error code = -197360
JVMSHRC337E Platform error message: semget : EDC5129I No such file or directory.
Commenting out #IJO="$IJO -Xshareclasses:name=cache1_%u" from the TOMSVXML member seemed to clear the problem
Release : 15.0
Component : TOMZOS (Tomcat)
Possible errors from interaction in the shared memory.
As stated, commenting out the #IJO="$IJO -Xshareclasses:name=cache1_%u" statement in the TOMSVXML
member seemed to clear the problem.
By default, CCS Apache Tomcat has the -Xshareclasses option to improve performance. CCS Apache Tomcat should be able to run under the same USER ID with any cache name. It does not specifically have to be "cache_%1u" .
See the IBM explanation, possible causes, and resolutuion of the JVMSHRC020E message.
