Environment

Product Version: 6.12

Resolution

When checking for a metrics_collector.so, we can see that the file is missing:

ls $GPHOME/lib/postgresql/metrics_collector.so

In this situation, the reason why the file is missing is because the incorrect version of Greenplum is being used. Furthermore,  v6.13.0 was downloaded from "Greenplum® Database by VMware Tanzu™" instead of "VMware Tanzu™ Greenplum®".

To confirm what version you are downloading, you can check on the download page in the Release Details.

The documentation team has been informed that the naming should be changed to add open source to avoid confusion.

The fastest way in this situation to clarify the current downloaded version is checking the file size. The open source is 62MB and the full version is 192MB.

Remove the open source version and download and install the full version.
