Summary :
The SAP JVM Switch tool can cause configuration issues with SAP JVM 4 replication using sapcpe, targeting system paths like /usr/ss//SYS/exe/run or :\usr\sap\\SYS\exe\run. This misconfiguration disturbs system updates via Software Update Manager (SUM). The issues arise due to the default kernel setting for DIR_EXECUTABLE not being explicitly defined in instance profiles. The solution involves reconfiguring the replication path to $(DIR_INSTANCE)/exe, editing profiles, adjusting services, and re-setting environmental paths appropriately. Detailed steps include directory establishment, sapcpe execution, service adaptation, and login environment correction, ensuring seamless system upgrades and Java integration.

Key words :
select registry key hkey_local_machine/system/currentcontrolset/services/saposcol, replace entry /usr/sap/<sapsid>/sys/exe/run, replace /usr/sap/<sapsid>/sys/exe/run, javahome=/usr/sap/<sapsid>/<instance>/exe/sapjvm_4, cd /usr/sap/<sapsid>/<instance>/sdm/programstopserver, /usr/sap/<sapsid>/sys/exe/run, \usr\sap\<sapsid>\sys\exe\run, \usr\sap\sapsid>\<instance>\exe\sapjvm_4, /usr/sap/<sapsid>/<instance>/exe/sapjvm_4, \usr\sap\<sapsid>\<instance>\exe\sapstartsrv
