com.pega.pegarules.pub.context.InitializationFailedError:

Steps to Reproduce

Not Applicable

Root Cause

A defect or configuration issue in the operating environment. Another node is using the same explicit temp directory on this system as this node (same SysNodeID Hash is being generated) . Systemout.log from this Websphere instance shows the location of the PegaRULES effective temp path.

[7/25/17 18:13:59:615 EDT] 000000a6 SystemOut O 2017-07-25 18:13:59,614 [your_host] [ ] [ ] [ ] (rnal.mgmt.InitialConfiguration) INFO - PegaRULES effective temp path: /your_usr/your_webspheres855/AppServer/profiles/Applications/temp/your_pega/your_PegaServer/your_prpcear/prweb.war

Resolution

There are a few different ways to solve this:

• Create a new URL under Default URL provider by the name url/initialization/explicittempdir and provide a value that is unique to this JVM. E.g file:///D:/Temp/PegaTempDir Then restart only this JVM. See page 35 and 36 of the install document for detailed instructions: https://pdn.pega.com/documents/pega-72-platform-installation-guide-websphere-and-db2-luw

Or

• Add JVM argument -Dpega.tmpdir=<PegaRULES effective temp path> and restart.

Or

• Add JVM argument -Didentification.nodeid=<your_uniqueNODE_ID> and restart.
