Products

• CA Automic Dollar Universe

Issue/Introduction

The Reporter Execution extraction fails with the following error in Reporter Server log (<reporter_server>/logs/server.log) since the upgrade to Reporter 6.10.x:

[ERROR] 07 May 2024 15:31:07 [pool-x-thread-y] com.orsyp.reppub.server.command.rep.ReporterExtract$1 - com.orsyp.reppub.common.exception.ServerException: java.util.concurrent.ExecutionException: java.lang.ClassCastException: com.orsyp.reppub.server.reporter.extractor.owls.OwlsExecutionsExtractor$VariableInserter cannot be cast to com.orsyp.reppub.server.reporter.extractor.owls.OwlsExecutionsExtractor$MessageInserter

The command used to launch the extractions is the following:

$UNI_DIR_ROOT/reporter_client/exec/uxrepadd EXT -REPNODE "Reporter_Node" -PRODUCT "ALL" -UVMS "ALL"

The Reporter Extraction Parameters values on this case are:

extractMessagesDuas = true
extractParametersDuas = true
extractVariablesDuas = true
maxParallelExtractions = 100

Environment

Reporter Server 6.10.x

Cause

Defect: when multiple extractions are running having sufficient load and more than one extract variable is set to True then there is a chance of having this exception.

Resolution

Workaround:

Upgrade Reporter Server to version 6.10.121 and then replace the attached RepServerJava.jar file on the subfolder exec and restart Reporter.

The error should no longer occur and concurrent extractions should work correctly.

Solution:

Update to a fix version listed below or a newer version if available.

Fix version(s): 
Component: Reporter Server
Dollar Universe 6.10.122 - Planned to be released November 2024
