GoldenGate logs are a powerful source of information<\/strong> when troubleshooting or analyzing your deployments<\/strong>. However, there is at least one log file per service in the Microservices Architecture. This means that for a GoldenGate setup with multiple deployments, you can quickly have tens of log files to search for information. In that context, knowing where to look is important<\/strong>, especially if you are upgrading from a Classic Architecture<\/a> where you only had to check the ggserr.log<\/code> file.<\/p>\n\n\n\n

REST API Log Files<\/h2>\n\n\n\n

The restapi.log<\/code> files are one of the most important logs because of the amount of information they provide. They allow you to completely understand what is happening behind the scenes. It takes time to learn how to analyze them, but I wrote a dedicated article on REST API log analysis<\/a> to help you through this. There is one restapi.log<\/code> file per deployment, because the REST API calls are always made to a specific deployment. This is also true when using a reverse proxy.<\/p>\n\n\n\n

These restapi.log<\/code> files are also a source of information for other GoldenGate log files. For instance, REST API logs on the AI Service will be cleaned and filtered before ending up in the log dedicated to the AI Service. This is another reason why you should understand the content of these restapi.log<\/code> files.<\/p>\n\n\n\n

Here is a log example from a restapi.log<\/code> file. Again, for more details, read the blog linked above.<\/p>\n\n\n\n

Admin Client Log File<\/h2>\n\n\n\n
Depending on your configuration, the adminclient<\/code> log file might not always be in the same location. More specifically, you can have multiple adminclient.log<\/code> files for a single GoldenGate installation. The reason behind this is that the logs go to the location of your OGG_VAR_HOME<\/code> environment variable. The adminclient.log<\/code> can be located in :<\/p>\n\n\n\n
    \n
  • In your Service Manager var\/log<\/code> directory, if your GoldenGate user has the Service Manager OGG_VAR_HOME<\/code> set in the environment.<\/li>\n\n\n\n
  • In your deployment var\/log<\/code> directory, if you change the OGG_VAR_HOME<\/code> environment variable when switching between deployments at the OS level. This is not recommended, as it can lead to multiple adminclient.log<\/code> files and mixed-up logs between deployments.<\/li>\n\n\n\n
  • In your GoldenGate binaries, if you misconfigured your environment and are calling the adminclient<\/code> with an empty OGG_VAR_HOME<\/code> variable. This is not ideal, as you could lose the log file after patching or upgrading.<\/li>\n<\/ul>\n\n\n\n
    There is not much to see in this file with the default logging configuration, but it can be used to troubleshoot connection issues with the adminclient<\/code>.<\/p>\n\n\n\n
    Service Manager Log Files<\/h2>\n\n\n\n
    Let’s look at the var\/log<\/code> folder of the Service Manager deployment.<\/p>\n\n\n\n
    oggsm\/var\/log:\nServiceManager.log\nrestapi.log\nAIService.log<\/code><\/pre>\n\n\n\n
    In GoldenGate 26ai, there are three different logs for the Service Manager:<\/p>\n\n\n\n
      \n
    • ServiceManager.log<\/code> : In a healthy installation, this log file should only contain logs generated when services start or stop. But if your Administration Server doesn’t start, this log is a good starting point for troubleshooting.<\/li>\n<\/ul>\n\n\n\n

          \n
        • AIService.log<\/code> : This is where logs from the AI Service are gathered. It mostly consists of a cleaned collection of the REST API logs from calls made against the AI Service. For instance, here is a log you can get when adding an AI Provider to the Service Manager.<\/li>\n<\/ul>\n\n\n\n

          Deployment Log Files<\/h2>\n\n\n\n
          GoldenGate deployments have more log file types than the Service Manager. In the var\/log<\/code> folder of your deployments, you should have the following files:<\/p>\n\n\n\n
          ogg_test_01\/var\/log:\nadminsrvr.log\ndistsrvr.log\nER-events.log\nextract.log\nggserr.log\npmsrvr.log\nrecvsrvr.log\nreplicat.log\nrestapi.log<\/code><\/pre>\n\n\n\n

          • adminsrvr.log<\/code>, distsrvr.log<\/code>, recvsrvr.log<\/code> and pmsrvr.log<\/code> : These files contain all the information, warning and error messages from actions or events in the main GoldenGate services (Administration, Distribution, Receiver and Performance Metrics Services). They are not as extensive<\/strong> as what you can find in the restapi.log<\/code> file, but they provide a really good overview of what is happening<\/strong> inside your deployment.<\/li>\n\n\n\n
          • ER-events.log<\/code> : This is a log file that can be used for monitoring your GoldenGate deployments. All warning and error messages on your extracts and replicats<\/strong> are available here. It is sometimes verbose, but still very useful for monitoring<\/strong>.<\/li>\n<\/ul>\n\n\n\n

                  GoldenGate Logs in the Web UI<\/h2>\n\n\n\n
                  In the GoldenGate web UI, you can access, filter, or query some of the logs listed above. From the Service Manager, the Diagnosis Log<\/strong><\/em> tab displays the ServiceManager.log<\/code> file with filtering options.<\/p>\n\n\n
                  \n

                  You can also quickly enable debug logs<\/strong> for the Service Manager, which is usually only needed when the Oracle Support <\/strong>requests it. This will generate a ServiceManager-debug.log<\/code> file in your var\/log<\/code> directory, and it can be downloaded from the web UI and sent to the Oracle Support or your dbi GoldenGate expert for analysis.<\/p>\n\n\n
                  \n

                  When connected to a deployment in the web UI, you can also view different logs.<\/p>\n\n\n\n
                    \n
                  • From the home page, the Critical Events<\/em><\/strong> view displays the content of the ER-events.log<\/code> file.<\/li>\n<\/ul>\n\n\n

They will respectively display the adminsrvr.log<\/code>, distsrvr.log<\/code>, recvsrvr.log<\/code> and pmsrvr.log<\/code> files. Similar to what I just explained, you can also enable debug logs temporarily if needed.<\/li>\n<\/ul>\n\n\n
