Workload Automation

I have noticed while working with CA Workload Control Center customers that one has to run multiple commands to recycle CA WCC services.

For example,

unisrvcntr stop/start CA-wcc-db

unisrvcntr stop/start CA-wcc-services

unisrvcntr stop/start CA-wcc

Although stopping one may stop the other, at times it is hard to remember which one goes first. Starting CA-wcc starts CA-wcc-services, CA-wcc-db has to be started/stopped independent of the other two and so on.

Just to simplify this a bit, I have attached two scripts to this document; one for WCC with native Derby DB (CA-WCC-DB) and the other (CA-WCC) for WCC using external DB (Oracle or MS SQL Server).

I have tested these scripts on Redhat and SuSE Linux server running WCC 11.3.6 and WCC 11.4. It is likely to work on AIX and Solaris as well, but I am yet to test it.

How to use these scripts?

1. Download and copy the script to /etc/init.d/ as "CA-WCC"

# ls -l /etc/init.d/CA-WCC

-rwxr-xr-x 1 root root 3522 Mar 20 11:35 /etc/init.d/CA-WCC

2. Edit the $CASHCOMP/csutils/config/casrvc.cfg file using a text editor (Ex: vim) and add the following line:

Note:

You may have other Main_Service_Entry lines based on other components installed on the WCC host.

For example:

Do NOT remove these lines. Leave them as is.

3. Test the script using commands:

Monitor

unisrvncntr status CA-WCC

Example:

------------------------------------  -------  --------------

Stop

# unisrvcntr stop CA-WCC

Example:

# unisrvcntr stop  CA-WCC

Executed CA-wcc stop.............................................OK

Executed CA-wcc-services stop....................................OK

Executed CA-wcc-db stop..........................................OK

Start

# unisrvcntr start CA-WCC

Example:

# unisrvcntr start CA-WCC

Executed CA-wcc-db start.........................................OK

Executed CA-wcc-services start...................................OK

Executed CA-wcc start............................................OK

Restart

# unisrvcntr cycle CA-WCC

Example:

# unisrvcntr cycle CA-WCC

Executed CA-wcc stop.............................................OK

Executed CA-wcc-services stop....................................OK

Executed CA-wcc-db stop..........................................OK

Executed CA-wcc-services start...................................OK

Executed CA-wcc start............................................OK

Executed CA-wcc-db start.........................................OK

CAVEAT(S):

1) On Linux, do NOT execute chkconfig CA-WCC on command after placing the CA-WCC script under /etc/init.d/. Doing so will change the order WCC and other services are started during System reboot.

Execute chkconfig CA-WCC --list to ensure all run levels are off.

2) Backup the $CASHCOMP/csutils/config/casrvc.cfg file before updating.

3) Save a copy of the updated scripts elsewhere so they can be restored if a product maintenance regresses the changes.

BACK-OUT PROCEDURE:

> Remove /etc/init.d/CA-WCC script

> Undo the changes to $CASHCOMP/csutils/config/casrvc.cfg file.
