Hi !
After migrate WMB from 6.0. to 6.1 i get this messages in the event log on the windows server that holds the Config Manager :
Event id : 1587
( xxxx ) The Configuration Manager ''xxxx'' is discovering the configuration of broker ''yyyy'.
How often is this messages being proceed to the event log ?
On every deploy or when the toolkit/proxy connect ? |

| I think you'll find that these occur about once an hour. |

Yes 
It takes appx. 30 min.to discover all brokers and in that time of discover the deployment is slow.
Is it possible to change the time frame ? |

| Yes, you can use the CMP API Exerciser to change the discovery interval, or turn it off completely. |

Which (negative) effects does it have when I change the discovery interval?
Is there any other possibility to change the value than doing it by the CMP API Exerciser?

The ConfigMgr has a larger chance of getting out of sync with the Brokers if you increase the discovery interval or turn it off entirely.
I don't think anything other than the CMP - through your own code or the API Exerciser - will let you change this. |

Correct, though you can also use the environment variable MQSI_SYNCTIMEMINSOVERRIDE (set to -1 to completely disable sync). |

After changing the value by CMP API I'll have to wait until ConfigManager syncs the next time in order to activcate the changed value. If I set the value to -1 sync gets deactivated. How long do I have to wait after changing the value to 60 before sync gets activated again?

If you disabled synchronization using the CMP, then when you re-enable it synchronizations will restart automatically within the next hour.
If you disabled synchronisation using the environment variable, if you then change the variable you'll need to restart the Config Manager.
BTW, the environment variable takes precedence over the value in the CMP. |

Thanks a lot for clarification! It works the way I thought / tested it would.
