In of our Webservice a user is not able to Invoke JVM, below are the
following error messages :

Could not create the Java virtual machine
System Information :
Z/OS : 1.12
*some of my try :*
I tried keeping *Xshareclasses:none *but no luck.
User has the Unique UID and GID assigned.
User has access to the Java Directory.
/tmp has the sufficient space
I even tried Killing the JAVASHARED resource but still no luck.
There were no ICH messages in the LOG to see if there are any Challenges
with RACF.
*Historical Details :*
Recently The system was upgraded to Z/OS 1.12, seclabel option got
activated but not sure how it happened since the prior RACF database didnt
had those options enabled.
*BPX setting interms of Parmlib :*

Some Research :
Using this error message : JVMSHRC337E Platform error message: semget
: "*EDC5163I
SAF/RACF extract error*." I ended up searching the IBM manual "
Language Environment Run-Time Messages " with below explanation
*EDC5163I SAF/RACF extract error. Explanation: *An authorization failure
occurred when attempting the service. This message is equivalent to the
z/OS UNIX System Services errno, EMVSSAFEXTRERR. *Programmer response: *Refer
to *z/OS XL C/C++ Run-Time Library Reference *for the function being
attempted for the specific reason for failure. *System action: *The request
fails. The application continues to run. *Symbolic Feedback Code: *EDC51B
Using the above recommendation I ended up searching : Refer to *z/OS XL
C/C++ Run-Time Library Reference *for the function being attempted for the
specific reason for failure. Below explanation were :
EMVSSAFEXTRERR An internal SAF/RACF extract error has occurred. A possible
reason is that the *username *access has been revoked. errno2 contains the
BPX1PWD reason code. For more information, see *z/OS UNIX System Services
Programming: Assembler Callable Services Reference*.
The above stuff says that "A possible reason is that the *username *access
has been revoked". Does it mean the user access is revoked in OMVS , if so
how can we activate the username access ? if my understanding is not right
please direct me in the right direction.
