Steps to Reproduce
- Open any VBD function.
- Click Generate Library.
Root Cause
The compilation errors are specific to ServerStatistics, NodeStatistics, and VBDService classes in a vbd-api JAR file. Triggering the below query, the results are as follows:
SELECT DISTINCT pzjar, pzcodeset, pzcodesetversion, pzlastmodified FROM .pr_engineclasses WHERE pzjar LIKE '%vbd-api%';
In the compilation environment, multiple versions of the vbd-api JAR files exist.
In the System Management Application (SMA), load the vbd-api-7.1.8.jar file.
The incorrect JAR file was loaded as the JAR files were present in two different code sets.
Resolution
Perform the following local-change:
- Delete the DATA-ADMIN-SYSTEM-SETTINGS PEGA-ENGINE!PROPERTIES/COM.PEGA.PEGARULES.BOOTSTRAP.CODESET.VERSION.PEGAMKT_DSM/DEFAULT Dynamic System Setting (DSS).
- Restart the server.
- Add all the nodes.
