Starting the Vantage Web STC after installing the client generated the following message:
JVMJ9VM082E Unable to switch to IFA processor - issue "extattr +a libj9ifa29.so"
Vantage Web Client Release 14.0.07
The filename.so file that is identified in the error message is not APF-authorized.
In order to verify the attributes of the file, on OMVS issue the following commands:
ls -lE /JAVA_HOME/lib/s390x/default/libj9ifa29.so
ls -lE /JAVA_HOME/lib/s390x/compressedrefs/libj9ifa29.so
This will return the information: -rwxr-xr-x aps- 1 USERNAM USERGRP 118784 Jan 11 2020 libj9ifa29.so
The bit that indicates if the file is APF Authorized is the first one in the bold text above. If this bit has an "a", the file is APF Authorized, if it has a "-" it is not.
In case either of the files have their APF bit off, go to the respective directory (JAVA_HOME/lib/s390x/default or JAVA_HOME/lib/s390x/compressedrefs) and issue the following command from the USS directory to APF-authorize the file:
extattr +a filename.so
