Known Issues
The following are the known issues for DX NetOps Mediation Manager 20.2.
  • The device pack does not appear in CA Performance Center 2.7 and later version.
    This issue occurs when you upgrade CA Performance Management from 2.6 or lower version to 2.7 and later version but use CA Mediation Manager 2.6 or lower version.
    To resolve this issue, follow these steps:
    1. Log in to Mediation Manager after you upgrade to version 3.7, and click the
      Device Packs
      tab.
    2. Select the sub component
      PRESENTER_CAPM
      ,
      and click
      Stop.
    3. Ensure that the
      PRESENTER_CAPM
      is selected, and click AdvancedAdvanced icon.
      The PRESENTER_CAPM
      window appears
      .
    4. Click
      Configuration
      on the right pane.
    5. Update the value in
      OUTPUT_DIRECTORY
      as follows:
      /opt/IMDataCollector/apache-karaf-2.4.3/MediationCenter/
    6. Click
      Save
      ,
      Close
      .
    7. On the Device Pack window, select
      PRESENTER_CAPM,
      and click
      Start
      .
    This issue can also occur if Mediation Manager is upgraded from version 2.7 to version 20.2 but
    PRESENTER_CAPM
    is not upgraded. In that scenario, either upgrade PRESENTER_CAPM or manually modify the OUTPUT_DIRECTORY value as specified in step 5.
  • DX NetOps Mediation Manager versions 2.4, 2.5, 2.6, 2.7, 2.8 fails to deploy device pack certificates in CA Performance Management version 3.0 or later.
    This is a compatibility issue. To resolve this issue, upgrade CA Mediation Manager to version 3.0 or later because the Mediation Manager versions 2.4 through 2.8 are not compatible with CA Performance Management version 3.0 or later.
  • DX NetOps Mediation Manager
    on Windows and Solaris Supports only Multi-Controller
    Even if the DX NetOps Mediation Manager Local Controller is installed on Windows and Solaris, you must manually copy the Queue folder (where the input files get collected) to the Data collector.
  • CAAVIController device pack supports single AVI Controller
  • CERT deployment fails when the corresponding CERT folders are zipped at the parent level
    The CERT deployment fails when the following folders are zipped at the parent level (CERT_<DevicePack_Name>).
    • components
    • device_mapper
    • metric_families
    • vendor_certs
    As a workaround, ensure that you zip the preceding four folders.
  • While installing Mediation Manager in Windows environment, make sure that JRE path should be an environment variable with JAVA_HOME name and bin directory of JRE shall be in path.
