The system / LPAR upgraded to Vantage 14.1 is now receiving the $HASP908 EXIT6 error messages
$HASP908 EXIT6: Vantage KNGED009 level (z/OS x.x) does not match the current JES2 level .
Why these messages are received?
When z/OS or JES2 are upgraded, the ARM JES2 exit should be reassembled. If the installer forgets to do that, then there will be a problem. For example, the DMSAR will not restore the data sets and therefore, the jobs/batch will be stopped. To prevent this from happening, the above informative message was created.
This message was introduced in the maintenance LU06367, and therefore the KNGED009 which the LU06367 delivers has been assembled and link edited on z/OS 2.5.
Please refer the KB article PTF# LU06367 - ARM JES2 EXIT6 IS DISABLED IF IT MISMATCHES JES2 LEVEL also.
