Setting STATE_DETAILS of a custom resource via the scriptagent is available in 12c. There is a specific output tag to be used : CRS_STATE_DETAILS. The other tags in 11.2 should result in the messages being displayed in the crsctl output. e.g echo "CRS_PROGRESS:Starting xyz" should result in "Starting xyz" being displayed in crsctl.
thanks for your reply. The problem is that the documentation does not state anything about the output format for the tags (CRS_XXX:msg). It just says something about a "tag", but not how this tag is applied. Meanwhile I've found the answer in the xa agents by oracle how the tags are applied and thanks to you for explaining it too. I found out that CRS_STATE_DETAILS also works in Release 22.214.171.124 (not sure about 126.96.36.199). Thanks for your Help!
