Hi Guys,

Recently while working on a Golden Gate setup Classic version 21 with XAG GI bundled agents version 9.1 (standalone deployment) on the top of Oracle 21.3.0 faced a strange issues where the GG failed to start and throwing errors ..

CRS-2672: Attempting to start 'xag.ggtest.goldengate' on 'host'
CRS-2674: Start of 'xag.ggtest.goldengate' on 'host' failed
CRS-2679: Attempting to clean 'xag.ggtest.goldengate' on 'host'
CRS-2681: Clean of 'xag.ggtest.goldengate' on 'host' succeeded
CRS-4000: Command Start failed, or completed with errors.

I checked for XAG errors in /diag/crs/crs_scriptagent_oracle.trc and I have observed that every time I try to start the GG, it prints “DATASTORETYPE 0 not found” in the logs but giving no hint about the cause.
Next I have checked for the version of XAG pointing to ($GRID_HOME/bin/crsctl stat res xag.ggtest.goldengate -f ) and it was pointing to the older version of the GG. It says 9.x was registered with the CRS even when the PATH is pointing to the new GG version 10.x

As an action next you will have to remove the GG resource from clusterware registry which is pointing to the old or incorrect version (9.x in my case).

[oracle@fatdba-07-test bin]$ /u01/app/grid/xag/bin/agctl remove goldengate ggtest

[oracle@fatdba-07-test bin]$

Once it is removed from the clusterware registry, next add the new version while pointing to the correct version.

[oracle@fatdba-07-test bin]$ ./agctl add goldengate ggtest --gg_home /ogg/newgg/version10.2 --nodes rac01,rac02 --vip_name ogg_vip --filesystems ora.acfs.oggvol.acfs --databases ora.racdb.db --oracle_home /u01/app/oracle/product/21.3.0/dbhome_1 --mo nitor_extracts ext1 --critical_extracts ext1

Start your Golden Gate now ... 

[oracle@fatdba-07-test bin]$ ./agctl status goldengate ogg_ha
Goldengate instance 'ggtest' is running on rac01

I highly recommend that you totally remove the old 9.x or any previous version to avoid such cases if they are no longer in use and there is no dependency on previous version.

Hope It Helped!
