Problem: SAP Mobile Server fails to start because of incorrect or conflicting JVM property settings.
updateProps.bat -nv "DJC_JVM_MAXHEAP=2048M"
While the SAP JVM options -XX:+UseParallelGC and -XX:+UseParallelOldGC can improve server performance, they may conflict with other JVM options set in the previous installation which can prevent SAP Mobile Server from starting.
Solution: If adding these JVM options prevents SAP Mobile Server from starting, run SMP_HOME\Servers\UnwiredServer\bin\restore-workingconfig.bat to restore the options to a working state.
