Steps to Reproduce


Root Cause

A defect or configuration issue in the  operating environment. The -Dcom.pega.sma.tempdir was incorrect. It must be -Dcom.pega.sma.tmpdir.


Make the following change to the operating environment:

Pass the system property as a JVM argument as below,


If the com.pega.sma.tmpdir system property is not specified, SMA proceeds as follows.

If Nodes.xml file is present in the directory specified by user.home system property, then this file is used. Else, the system looks for Nodes.xml in the directory specified by the javax.servlet.context.tempdir property retrieved from the ServletContext object, and creates the file if it does not exist.
