Simple way to get rid of OGG-01525 for AdminClient

While installing Oracle GoldenGate 19c tonight, I was wanting to work from the command line and play around with AdminClient. For those who are not up to speed, AdminClient is the replacement for GGSCI when using Microservices.

AdminClient in Microservices provide the same functionalty as GGSCI, but it is a thin, lightweight tool that can be installed on a remote linux box or windows desktop/laptop. It allows you to make simple GGSCI commands and convert them into RESTP API calls on the backend. All the while, providing the same command line interface as GGSCI provided.

It is great that there is still a command line option for Oracle GoldenGate within the Microservices Architecture, however, when you start it you get presented with a Warning. The Warning is an OGG-01525 message that states there is no place to produce a trace file for the session.

WARNING OGG-01525 Failed to open trace output file, ‘/opt/app/oracle/product/19.1.0/oggcore_1/var/log/adminclient.log’, error 2 (No such file or directory).

So how do you fix this issue?

Note: This is not a bug! AdminClient was designed this way.

In order to fix this issue and get rid of the warning, you need to set a new enviornment variable. Since Oracle GoldenGate Microservices has been out for a bit over 2 year, I guess the environment variable isn’t that new. Any ways, the environment variable that needs to be set is OGG_VAR_HOME.

export OGG_VAR_HOME=/tmp

The OGG_VAR_HOME variable is used to tell AdminClient where to keep the adminclient.log file. In my example above, I’m using the temp ( /tmp ) directory for the log file.

Now, there is only one problem with the OGG_VAR_HOME environment variable. This environment variable along with OGG_ETC_HOME have to be set per Deployment Home environment. Meaning, when you have more than one Deployment Home, these environment variables are specific to that deployment.

The question that is begging to asked is -> How do I assign an environment variable for AdminClient and Deployments at the same time?

To solve this problem, I just wrote a simple shell wrapper and placed it in my home directory. The script looks like this:

[oracle@ogg19c scripts]$ cat adminclient.sh
#/bin/bash

export OGG_VAR_HOME=/tmp

${OGG_HOME}/bin/adminclient

Now, I can run the shell script and execute the AdminClient without getting the OGG-01525 warning.

[oracle@ogg19c scripts]$ sh ./adminclient.sh
