Problembeschreibung: | |
On Redhat Enterprise Linux 5.5 there is an issue with the "su" command that is used in the hadrV95_start.ksh scripts to determine the server status. If the command gets killed by db2V95_start.ksh script - that can execute in parallel - then the return code of the su command remains 0 (zero). For TSA this indicates a false "successfull" startup and a potential failover will not be performed. In Linux system log (/var/log/messages) you will see the following messages: Oct 15 16:14:08 lx252 db2V95_start.ksh[2176]: *************** Attempted to start partition db2inst1,0 and failed Oct 15 16:14:08 lx252 db2V95_start.ksh[2177]: Killing db2 processes : db2inst1, 0 Oct 15 16:14:08 lx252 /usr/sbin/rsct/sapolicies/db2/hadrV95_start.ksh[2185]: ...returns 0 Oct 15 16:14:08 lx252 /usr/sbin/rsct/sapolicies/db2/hadrV95_start.ksh[2186]: Returning 0 : db2inst1 db21inst1 PDB2UID Note: This has been addressed already partially in APAR IC72271, db2gcf does not get killed anymore by the db2V95_start.ksh script. Unfortunately, there are two places in the script, where kill -9 is called, but only one call was fixed. This APAR will address the second call as well. | |
