restart event subsystem

I am not using the OpenJMS, DB but rather SQL Server. TS 6.7.1 on Win2K.

Event Subsystem (and thus TS Index) start before SQL server does, so they fail.

Using Services -> recovery I changed it to restart after 1 minute on failures.

However they never start (and the log files do not update, so I suspect the restart is not happening.)

Is there a special trick for restart ? How about making event subsystem wait until SQL server is running ?

If I manually start the services they work fine.

Tips/Pointers/RTFMs appreciated

i know you are on windows? Smiley Happy

If they are all in the same server, then I think you can make TS indexing/event subsystem services dependant on SQL services to come up first... by editing/adding "DependOnService" in the registry
If they are in different servers then I don’t know if you can do dependency "remotely"...

run regedit then:
HKEY_Local_machine/system/currentControlSet/services/"name of the service you want to be dependant on another service"

right click on that service >new >String value

and you can add string value with name = "DependOnService" with value = "name of sql service"

You can setup dependencies for window services so that the eventsubsystem service can be dependent on the sql server service (IE make sure sql server is running before starting the eventsubsystem).

If you go to the services screen on your windows box and view the properties of a service, you'll see a dependencies tab.

How you configure it - I don't know... ask your sys admin Smiley Happy

That tab is readonly. I will try the regedit in the previous suggestion.

OK, so that worked for Event Subsystem, about tsindex ? It is already dependent on tsserver so can you have 2 ? Or just delete the tsserver entry and make it event ?

Thanks

i never tried it, but i think you can have as many dependancies as you need Smiley Happy

... maybe you can go back to regiedit where name = "DependOnService" and modify the value to value = "name of sql service; name of anothercerivece; 3rd service..."
notice ";" and maybe there should not be any space in there "service1;service2;"... and you can check if it worked by going to services window, right click on the service, and look at "dependancies tab"

but i think TSindex needs to depand on event subsystem service correct?
let me know if works Smiley Happy

Yes ! if the event based updates are configured.
You need not have the strict start time dependency as search can be configured to wait-retry-connect with the eventsubsystem. If after the configurable time/attempts it is not able to connect indexer will not start firsthand logging the appropriate error.

Modify the following properties in search.properties
=================================================
# Number of times Index server attempts to listen to
# TeamSite event system before giving up
iw.index.events.listen.attempts=10
# Number of seconds Index server waits between attempts to listen to
# TeamSite event system
iw.index.events.listen.wait=12

=================================================

I am surprised that 10 retries 12 seconds apart is not enough, but I will up those. Thanks.

also keep in mind that making IWov services dependant on something else is not "supported"... as far as i remmber and saw, by the default all teamsite services are not depandent on anything, so if it happens that you need the support to troubleshout something, they will say "if they see it" that there shouldnt be any dependancies...

One good way to manage TS services is using iwreset with proper switch. It takes care of the ordering and dependencies.

This is for the start time, once up (able to connect) search always keeps probing and trying to reconnect if the eventsubsyetm goes down. Meanwhile user can still perform the searches.
