I just received the procedure on what they are doing. Maybe this will help.
Hot Fix Upgrade
A compressed tar file will be placed in /srv/ftp/applinx and an email will be received from Curtis about the file.
Important – Please see noted ISSUE at the bottom of the document before starting this procedure
Uncompress the file
Move the file to /SAG/sagprod
Make copy of current apx directory to a new directory
Untar the file from this location
Next untar the applinx tar file that was extracted.
Update the start-gxserver.sh file
Go to the bottom of the file and modify as follows:
a) Add in –Xms1024m
b) Change the –Xmx###m to –Xmx2048m
c) Add in –Xcompactgc
The line should look like the line below
$JAVA_HOME/bin/java -Xms1024M -Xmx1024m -Xcompactgc -Xbootclasspath/p:"$_BCP" -classpath "$_CP" "-Dcom.sabratec.gxhome=$GXHOME" "-Dcom.sabratec.license=$SAG/common/LKey/" com.sabratec.applinx.server.runtime.GXServerContextStart &
chmod 755 on the following files in /SAG/sagprod/apx/v525/:
Stop and restart all of the gx processes by running /home/prdcntl/stopALL
Once completed, contact the customer for verification.
/SAG/sagprod/apx/v524/config – the 2 files listed below have to be saved and moved back in once the untaring was completed.
