List all installed plugins
After upgrading APEX I found this query useful to review all the plugins I had installed across multiple workspaces and in multiple applications to find ones that needed to be upgraded.
select name
,plugin_type
,version_identifier
,workspace
,application_id
,application_name
from APEX_APPL_PLUGINS
where workspace not in ('INTERNAL','COM.ORACLE.CUST.REPOSITORY')
order by name, workspace, application_id;
