JWP startup script

[Michael A. Lowry]

When troubleshooting single sign-on, it is useful to start the Java Work Process with Kerberos debugging enabled, and with a customized krb5.conf file. To facilitate this, I wrote a small Bash script. This complements the UCDJ startup script I wrote earlier.

 

We start all the normal WPs and CPs the traditional way, via a Service Manager. When troubleshooting the JWPs though, we start these using this script instead of via the SMgr. This script is designed to work on any of our servers, and we have individual INI files for each environment and node. You’ll have to customize the script for your needs. Enjoy.

#!/bin/bash
shopt -s extglob
# Lists of servers in each staging environment
EXP_SERVERS='@(expa|expb)'
EXP2_SERVERS='@(exp2a|exp2b)'

# Lists of primary and secondary members of clusters
PRIMARY_SERVERS='@(expa|exp2a)'
SECONDARY_SERVERS='@(expb|exp2b)'
