Known problems and their workarounds

Problems and their workarounds in IBM App Connect Enterprise.

  • Contributing the same monitoring event to more than one business transaction definition on the same integration server creates duplication (#88007)

    In cases where a single integration server hosts the definition of more than one business transaction definition, and the business transaction definitions use the same monitoring events, subscriptions will be created such that the monitoring events will be registered against all the business transaction definitions. This can lead to an incorrect business transaction status being reported (for example, if two start events are involved, then the transaction status will be shown as inconsistent).  You can work around this issue by defining each business transaction definition on a different integration server.

  • The command ibmint generate tests does not support relative paths on windows (#86166)

    You can work around this issue by using an absolute path when you pass in the value for the recorded-messages parameter on the ibmint generate tests command.  This issue is fixed in IBM App Connect Enterprise

  • IBM App Connect Enterprise Linux on Z for IBM zCX Multilingual (G01T5ML) contains an incorrect FMID, which prevents support cases being raised.
    You can work around this issue by installing an updated version of IBM App Connect Enterprise
