Retrieving class info from Atrium CMDB.
The publication was not succesful: Publish validation of IM(s) failed.
Detailed failure message(s) can be found in the request log.

The publish request log shows:

Failure Message: Class info is not synchronized.

1. Open a command line on the TSIM server, cd into a temp directory (i.e. c:\temp for Windows or /tmp for Linux) and run:

pclassinfo -x -o mc_sm_object.baroc.

This will create a new file called mc_sm_object.baroc in the current working directory.

2. Copy the new mc_sm_object.baroc to <installationDirectory>\pw\server\etc\<cell>\kb\classes directory.

where <cell> is the name of the TSIM server cell.

3. Run the following command to compile the cell Knowledge Base (KB):

mccomp -n <cell>

4. Run the following command to reload the cell KB:

mcontrol -n <cell> reload kb

5. Once the cell is up (confirmed with 'mcstat -n <cell>' or 'pw p l' command), run the following command to confirm that class information is in sync:

pclassinfo -n <cell>

it should return as the last line:

Class info is synchronized.
