8 Known Issues

This section describes the following known issues that you may encounter when you install and configure the Enterprise Manager Plug-In for Oracle GoldenGate.

8.1 Download Failure

When downloading the Oracle GoldenGate Enterprise Manager Plug-In as previously described, you may encounter an error when the download it initiated. The output would look like this:

Downloading file in staging directory
/scratch/aime/WORKEM12104/mw2587/gcinst2587/em/EMGC_OMS1/sysman/stage/034148593e245c3de050f00a82634a7f ...
Staging directory cleaned up.

response. Status Code = 200, Response Text = [OK | <results>
   <error>
       <id>10-013</id>
       <message>Choose valid parameters.</message>
   </error>
</results>
]

To solve this problem:

  1. Clean up in the self update location. For example:

    Middlewarehome/gcinst/em/EMGC_OMS1/sysman/cache/selfupdate
    
  2. Check whether Enterprise Manager is pointing to staging or production. If it is pointing to staging, then run the following command to point to production:

    emctl set property -sysman_pwd welcome1 -name oracle.sysman.emSDK.core.mos.mos_url -value https://support.oracle.com
    

8.2 Upgrading the Monitor Agent

To upgrade Oracle GoldenGate Monitor Agent 12c version 12.1.3.0.4 to 12.2.1.0.0 for Enterprise Manager Plug-in, use the command touch cfg_templates/oggmon.properties && ./upgradeToMonitorAgent1221.sh instead of ./upgradeToMonitorAgent1221.sh command.

8.3 Undeploying and redeploying the same version of Enterprise Manager Plug-in

We do not recommend that you undeploy and redeploy the Enterprise Manager Plug-in version 13.2.1.0.0 as it can cause some unexpected errors. For example, if you navigate to Oracle GoldenGate home page from the Oracle GoldenGate Enterprise Manager Plug-In interface and click on Extract after you’ve undeployed and redeployed, you can get an error as shown.
