  • 1.  A bit of reverse engineering on oncmsm

    Posted Tue February 18, 2020 06:25 PM
    Hi Folks.

    A simple question:

    I know you have to start the connection manager using the command using omcmsm -c <config file>.  But once it's running, how do I locate the config file that was used to start it in the first place?  I have not found a oncmsm --status option and onstat -g cmsm does not tell me this.

    Have I missed something or is there a hack that will give me this info?  A sysmaster table, perhaps?

    Thanks much.

    Hello Jacob,

    I'm not sure if there is an option to check the connection manager's configuration file with oncmsm or onstat command.
    If you started with the oncmsm -c option, you can check the configuration file with the ps command as shown below.

    If you reloaded the configuration file with the oncmsm -r -c option, you should look in the connection manager's log file.

    I would like to know if there is another way.

    Perhaps use lsof and see if the connection manager still has the configuration file open?

    Hi Jacob

    If running 'ps | grep oncmsm' doesn't answer your question, then there are 3 sysmaster tables that relate to Connection Manager: syscmsmsla, syscmsmtab, syscmsmunit; the first of which contains the SLA details you have defined. Taking the sla_name column value and then doing some reverse engineering by grep'ing for that name in your Connection Manager *.cfg files may get the information that you want.

    Hi.


    "Perhaps use lsof and see if the connection manager still has the configuration file open?"

    Although some interesting output it doesn't keep the $CMCONFIG open.

    "ps | grep oncmsm" will most likely return ... nothing.
    "ps -ef | grep oncmsm" will most likely return ... the command line used to start the CM.

    Doh! Yes, forgot the "-ef".

    An alternative to:

    $ ps -ef | grep oncmsm
    informix 103736 2023 0 11:36 ? 00:00:00 oncmsm -c /products/14.10.FC3/etc/cma.cfg
    informix 104079 3367 0 12:09 pts/1 00:00:00 grep --color=auto oncmsm

    $ su
    Password:
    # cat /proc/103736/cmdline
    oncmsm-c/products/14.10.FC3/etc/cma.cfg#
