"re-registration of the message recovery thread only if settings have changed" . "Currently, every time a Process Server application target JVM is re-)started, a re-registration of the Work Manager message recovery thread with the BPEScheduler happens (CScopeProvidedBea n.reRegisterCleanup()). This requires the cancellation and re- creation of a scheduler entry through scheduler APIs. In a dis- tributed platform high availability environment or on a multi- servant setup on zOS re-registrations can happen multiple times (redundantly), due to the number of JVM starts. However, generally the re-registration is only required, if the configuration settings for th recovery thread have changed. have changed. The fix will introduce this conditional re- registration, thus greatly reducing the number of re- registrations."
Problem Description: When using WorkManager based navigation, on server restart in a clustered environment, the following assertion may be observed in SystemOut.log: Assertion violation !(Cannot schedule Message Cleanup) in method >> com.ibm.bpe.framework.navigation.CScopeProviderBean.reRegisterCl eanup(CScopeProviderBean.java:198) Problem Summary: Currently, each time a Process Server application target JVM is (re-)started, a re-registration of the Work Manager message recovery thread with the BPEScheduler happens (CScopeProviderBean.reRegisterCleanup()). This requires the cancellation and re-creation of a scheduler entry through scheduler APIs. In a distributed platform high availability environment re-registrations can happen multiple times (redundantly), due to the number of JVM starts. Under unfavorable circumstances, this can lead to deadlocks and unavailability of the Scheduler. Problem Conclusion: Re-registration is only required, if the configuration settings for the recovery thread have changed. The fix will introduce this conditional re-registration, thus greatly reducing the number of re-registrations."
Problem will be fixed with V7512
