Not everything that uses JAVA gets the benefit of excuting /etc/profile, which is where JAVA_HOME is set for our systems. We have many places where sysprogs, developers have to code a JAVA home. It would be a major headache at system upgrade time to notify everyone that on this date/time they need to update their JAVA_HOME variables from V7 to V8. There are config files for CICS, DB2, RDz, EKM, TOMCAT, application code, etc that all code a JAVA_HOME. My apache webservers, including PKI also have their own variables for home directory for IHS, because IHS, comes delivered with verion/release in the pathname. I don’t want to have to go into every instance of httpd.conf to fix it on the fly with an upgrade.
Some time ago, I went to the effort to symlink JAVA and communicated that to all, and we have had seamless upgrades ever since. Just prior to upgrade IPL, I change the symlink to point to the new version(if necessary), and then IPL. The world is good. _________________________________________________________________ Dave Jousma Assistant Vice President, Mainframe Engineering david.jou...@53.com 1830 East Paris, Grand Rapids, MI 49546 MD RSCB2H p 616.653.8429 f 616.653.2717 -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of David Crayford Sent: Thursday, January 21, 2016 8:06 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Where's Java!?
