How to get package/application info?

[Daniel Woo]

Hi all,

I am trying to create a script for maintainenance purpose, my challenge is to figure out what applications are in a specified package, I think I get get it via script, command line or config files. Does anybody know how to do this?

Regards,
Daniel

show_patches

to check what kind of patch (ux)
swlist â l patch

and comand
what
on core (main) file of application

Thanks for your help, but I mean to find what applications are in a MC Service Guard Package.

Since the logic to start or stop your applications is put in the customer_defined_{run|halt}_cmds() function of the pakages' control scripts you will have to parse these files.
But this is too specific and dependant on the scripting style of the person who supplied this functionality to give any general recommendations how to extract this info.

One can only generally extract where this logic is hidden by parsing the cluster config like that:

# cmviewconf|grep -E 'package (name|(run|halt) script)'

Hm, if you are content with identifying the resources a package constitutes you could make the control script word readable (provided they don't contain any passwords that you pass this way to get an application started (e.g. DB startup, but would be bad practice anyway).
Then your maintenance process could simply source it and access the defined resource array variables.

e.g.

$ . /etc/cmcluster/package/package.ctl

IP addresses:

echo ${IP[*]}

Mount Points and LVs:

echo ${LV[*]} ${FS[*]}

etc.


As you can see, this wouldn't require any contrived parsing (which in turn maybe even would require some grammar definition).

I think I can set some limition on the script names, so your solution is engouh in our case.

Thanks!
