Hi folks

I believe Actian Director uses something called Management Server. Further, I believe Director (and thus Management Server) is a prerequisite for DataConnect/IngresConnect.

The Ingres documentation indicates the Management Server can be started/stopped with the ingstart/ingstop -mgmtsvr option, however I don't see a way to explicitly show it is running or not (ignoring ps -ef).

For example, ingstatus doesn't show anything, even though it does show things that aren't running, like the Bridge Server. Issuing ingstop -mgmtsvr when Management Server is not already running, doesn't report too much and there is no "show mgmtsvr" iinamu command, for example.

Is it simply a case that Ingres can't report on something that is not installed?

Essentially I want to confirm a user could not run Director and/or DataConnect/IngresConnect without the DBA's knowledge, because Management Server would need to be running on the server?

Thanks
Steve

iinamu refers to the remote command server as RMCMD not MGMTSVR as you
would think. Here's what I see on one of my boxes:

ingres@loathing: /opt/Ingres/IngresII/ingres/utility
> iinamu show servers
RMCMD * 33603
STAR * 41865
DASVR * 35219
COMSVR * 34401
INGRES * 43787 (sole server)
IUSVR * 38803
IINMSVR * 33845

In a 11.1 installation here where the management server's not running (in config.dat ingstart.*.mgmtsvr is set to 0), ingstatus includes a line "Ingres II Management server (mgmtsvr) - not active".
I don't know why it's not showing you anything, ingstatus is a shell script so it may be possible to step through it to work out what's happening. Maybe there are version-dependent differences.

If mgmtsvr isn't running there won't be anything listening on the port Director tries to connect to. I would guess that doesn't stop clients from firing it up, it just won't find a target.

I recommend opening a support case, I was not aware that DataConnect needed the management server (I thought it only needed ODBC access).

Thanks. I am told by Actian Support that Management Server and thus Director is not available for Solaris SPARC. Probably makes sense; my understanding is there are very few customers running Ingres on Solaris SPARC.

I see the ingstatus script greps the config file, like you indicated, to determine if Management Server is installed.

If Management Server is not running, the script will only print something if it's installed. I guess that makes sense.

Thanks
Steve

Thanks Chris. Here is the prerequisite information for IngresConnect*. I hope they are not just prerequisites for the sample projects!?!
https://docs.actian.com/dataconnect/11.0/index.html#page/User%2FPrerequisites_2.htm%23ww610652

Actian Support indicated a licence file is required for DataConnect/IngresConnect. We don't have any such licences.

*=IngresConnect is DataConnect limited to Ingres.

Thanks

Apologies, Actian Support informed me Director is NOT a prequisite for DataConnect/IngresConnect.

I thought it was based on the following link. However, the prerequisites listed were for the IngresConnect SAMPLE PROJECTS, not IngresConnect itself.

DataConnect 11 User Guide > 25. Using IngresConnect Sample Projects > Prerequisites
