On App Visibility portal and App Visibility collector 10.5 in an HA environment, pg_xlog files are not deleted automatically and fill up disk space

If Version 10.5 of the App Visibility portal and App Visibility collector are running in a high availability (HA) environment, pg_xlog files are not deleted automatically from the installationDirectory\ADOP_DB\pgsql\data\pg_xlog folder and fill up the disk space on the hard drive. Eventually, this overloads the App Visibility portal and App Visibility collector and the server fails.

Workaround

1. In the HA environment, for each active node of the App Visibility portal and collector, make a backup copy of the postgresql.conf file, located in the installationDirectory\ADOP_DB\pgsql\data folder.
2. Edit the original postgresql.conf file in the installationDirectory\ADOP_DB\pgsql\data folder.

3. Add the following command to the end of the file:

   archive_command = 'cd .'

4. Save the postgresql.conf file.

5. Restart the App Visibility portal and collector services.
   If the App Visibility portal or collector cannot be restarted, restart the App Visibility PostgreSQL service and then start the portal and collector.

6. Repeat Steps 1 through 5 for each standby node of the App Visibility portal and App Visibility collector.
