I am seeing the following errors while stopping execution server.
| Quote: |
14:24:56 FMC10510I Execution server instance stopped.

14:24:59 FmcSQLException, Sqlcode=-1224, Sqlerrmc=, Sqlerrp=SQLERACM, Sqlerrd[0]=0, Sqlerrd[1]=0, Sqlerrd[2]=0, Sqlerrd[3]=0, Sqlerrd[4]=0, Sqlerrd[5]=0, Sqlwarn= , Sqlstate=55032 |
Please let me know if some thing is wrong with the FMCDB? or workflow setup[/code] |

What platform are you on?
How are you stopping the workflow product?
The SQL error you are getting in the execution server shutdown is:
SQL1224N A database agent could not be started to service a request, or was terminated as a result of a database system shutdown or a force command
Did you stop your database before stopping workflow? Or if you have the database server on another machine, did you loose your connection to the DB2 server? |

I thought I could get away without telling the background 
our workflow servers run on AIX and our webclient runs on windows2000,IIS, websphere.
Our workflow system started fine and then after few hours users started getting
timeout errors on workflow. We restarted webclient web application and rebooted webserver as
we have seen some TCP/IP communication(MQ errors) on event log. Still we were getting
time out errors. Then we have asked our AIX support to stop workflow servers and restart.
As i understand the servers basically will be stopped thru IBM supplied utilities and
restarted. I do not think FMCDB instance is touched while doing this.
While stopping the servers, I have noted the above mentioned error. |

When stopping the Workflow servers on AIX (or any unix platform) you must use the fmcautil command (The admin utility) to stop the servers. Do NOT just kill the processes. If you are just killing the processes, then you should run the fmcclean command to cleanup the environment (I believe this does the ipcs and ipcrm functions.
On your webclient machine, do you have a qmgr installed and do you have that qmgr clustered with the Workflow qmgr on the AIX box? If not, then your webclient is acting as a MQ client and therefore you are probably running out of channel connections. By default, the max channels is set to 100. MQ log files should contain an error stating max channels has been reached. It is recommended that you have the MQ server (a qmgr) installed on the same machine as your web application server machine.
If none of this helps, you may need to open an item with IBM support so they can review the log files for MQ, MQ Workflow, DB2 and possibly WAS so they can determine the cause of the problem. |

Hi,
In my experience this happens if the database manager and mq queue manager go out of sync from transaction co ordination point of view. that is if the database manager has been re-started after the queue manager hosing workflow server has been started, this error might appear.
Verify the mq queue manager error logs for any XA related errors. Please stop workflow server using the fmcautil, then stop and start the mq queue manager and then try starting workflow. May be you might have to restart the database manager also afresh. (but follow the sequence, db->mq->workflow)
