Explaining the usage of sgesap_validation.sh and sgesap_validation_wrapper.sh scripts
The purpose of SGeSAP (Serviceguard extentions for SAP) is to integrate SAP start and stop functions into a serviceguard package. However, from experience we know it is easy to forget a critical setting or definition in the package configuration file. Furthermore, these little mistakes are not always easy to spot. This was the main reason why we developed this script to inspect the ASCII serviceguard package file before bringing the paqckage into production. In the meantime the script evoluated that it is now possible to inspect live (running) packages as well.
From the start SGeSAP packages were in scope, but that does not mean we cannot verify non-SGeSAP packages as well. We will show you with some examples.
WARNING: this script will only work on Serviceguard version 11.20 and higher and is writtin for HP-UX 11.31. However, with minor modifications it can work on Linux as well
The script must be run as root (sorry!) and without any argument it will show you the usage:
#-> sgesap_validation.sh
Usage: sgesap_validation.sh [-d] [-s] [-h] [-f] [-M mail_address] package_name
-d: Enable debug mode (by default off)
-s: Disable SGeSAP testing in package configuration file
-f: Force the read the local package_name.conf file instead of the one from cmgetconf
-m: Monitor mode (less output) shows only warnings and failed lines
-M: Add one or more mail addresses with "mail-address1, mail-address2"
-w: SAP WebDispatcher
-h: Show usage [this page]
The must have argument is package_name (use the -f option for a new package which is not yet running). We assume that package_name resides under /etc/cmcluster/package_name/package_name.conf.
To verify a running package on the cluster (use cmviewcl to see them) we can use the following command (the package does not have to run on the node where you run the sgesap_validation.sh script!)
#-> sgesap_validation.sh jdbciPDS

Another shorter example is using monitoring mode which will only show warning and errors and therefore, shrink the amount of output drastically (if all is well of course):
#-> sgesap_validation.sh -m dbciRSS

While we are discussing the monitoring process we can introduce the sgesap_validation_wrapper.sh script, which as the name applies is a wrapper script around the sgesap_validation.sh script. It takes the output from cmviewcl and will inspect all running packages (with -m option) and will mail in HTML format the output to the destination defined in the script (variable ToUser). Run it without arguments as following:
#-> sgesap_validation_wrapper.sh
