Background documentationRequirements for Free Disk Space Locate this document in the navigation structure

 

You have to make sure that there is enough free disk space for the archives that you download on SAP Service Marketplace at service.sap.com.

Patching SAP Kernel, SAP JVM and IGS

During SAP kernel, SAP JVM or IGS patch, JSPM extracts the archives to a temporary directory under the /usr/sap/<SID>/<Instance name>/j2ee/JSPM/tmp directory. If the total size of the archives is X MB, there must be about three times X MB free disk space. When the patch is completed, the temporary directory is deleted.

If you have a heterogeneous cluster, this procedure is repeated for each separate kernel. When each kernel patch is completed, the temporary directory is deleted.

Patching Java EE Components

Depending on the Java EE components, some AS Java containers require additional free disk space. There must be at least enough free disk space to extract all software deployment archives inside the SCAs.

Additional

JSPM requires about 100 MB free disk space (depending on system size and frequency of JSPM use) under the /usr/sap/<SID>/<Instance name>/j2ee/JSPM directory for log and data files.
