Problem IC77264
|
Status: Closed |
DB2 HA SCRIPT HADRV95_START.KSH CAN RETURN WITH RC 0 ON REDHAT LINUX AND AUTOMATIC FAILOVER WILL NOT BE PERFORMED |
| product: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
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

/usr/sbin/rsct/sapolicies/db2/hadrV95_start.ksh[2186]: Returning

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. |
