Creating an application under VCs

[mokkan]

Hi,

If I need to create a script and need to run under VCS.  Do I need to follow any format? Or can I create the resource under application and just run  it  like below? Or do I need to follow VCS framework?

Here is the sample main.cf

Application   App_Testing (
         StartProgram = "/etc/VRTSvcs/app_online"
         StopProgram = "/etc/VRTSvcs/app_offline"

Here are the script.       

cat /etc/VRTSvcs/app_online

#!/bin/bash

#Start daemon
/opt/app/script/appscript start


cat /etc/VRTSvcs/app_offline
#!/bin/bash

#Start daemon
/opt/app/script/appscript stop

You also must use at least one of the following attributes:
MonitorProgram
MonitorProccesses
PIDFiles

If you application doesn't have any processes, then you can just create and remove a file in StartProgram and StopProgram and check file exists in MonitorProgram

Exit values for StartProgram and StopProgram should be 0 and:

MonitorProgram can return the following VCSAgResState values:

OFFLINE value is 100 or 1; ONLINE values range from 101 to 110 or

0 (depending on the confidence level); 110 equals confidence level of

100%. Any other value = UNKNOWN.

You can look at using Process Agent as well

You can look at entry points for process agent here

Also, please check that the start and stop scripts return after starting/stopping the application. If that is not done, then the online and offline operations of the application resource will timeout.

And as mentioned by Mike, specify atleast one of the 3 monitoring attributes: MonitorProgram, MonitorProcesses or PidFiles, depending on what is convenient for your application.

Process Agent may be a better choice for your requirement.

Please locate the Documentation for your OS and SF/HA combination on https://sort.symantec.com/documents and download the Bundled Agent Guide for detailed config info for Process and Application agents.

Thank you guys.  I  looked at the guide and still have some questions.

 I just want to run the script and I don't want to monitor it. Is there a way to do without selecting application as type?

For an example, I want run few simple scripts using VCS, but I don't want to do like startProgram or stopProgram or monitor.

LIke trigger or some thing ...

You can use triggers - see VCS admin section "VCS event triggers" for a list of triggers and how to use them.
