HORCM instance check
Hi,
Is there any command available to check which instances are running for BC and CA.
=================================
How should i differentiate between BC and CA instance using command line.
Regards
Rkumar

Re: HORCM instance check
I usually try to start the instance and it's already started it will say that it's already running.
The HORCM instance is a service and it doesn't differentiate between BC or CA services, only difference can be see in HORCM*.CONF file (CA doesn't use MU#).

Re: HORCM instance check
By default HORCM commands are directed to CA. To direct commands to BC you need to set the following environment variable -
HORCC_MRCF=1
This variable needs to be visible to your shell.
To see if a HORCM instance is running depends on your OS. On Windows takmanager should show your instance in the list of running processes. For Unix it should be listed via ps.

Re: HORCM instance check
Hi Kumar,
To check the running horcm instances,
In UNIX,
# ps -aef|grep horcmd
the output will be like this,
# ps -aef|grep horcmd
root 15361 1 0 11:17:54 ? 1:04 horcmd_0360
root 15376 1 0 11:18:03 ? 1:04 horcmd_0361
In this example, the instances 360 & 361 are currently running.
In Windows,
You can use the task manager window to see the process running with name that starts with horcmd.
Difference between BC & CA
=========================
By default all command sent for CA purpose (if there is no HORCC_MRCF variable set).
If you want to send the commands for BC purpose you have to set the HORCC_MRCF=1 variable.
Unfortunately there is no straight method to check the difference.
However, to check whether it's CA & BC pair, just run the "pairdisplay" command for the group and check the serial no. of pair volumes. If it's a diff serial no. (unless until there is no loopback CA configured), then it'a a CA pair. Else it should be BC volume.
cheers,
saran
