srvctl

After upgrading RAC database to 10204 and applying CRS bundle patch-1 for 10204 crs home,
srvctl command fails to startup resources on rac nodes. While starting up RAC resources using SRVCTL
following error occurs in CRSD.log file:

$ srvctl start instance -d rac -i rac2

2009-04-09 13:45:22.091: [  CRSRES][2611477408][ALERT]0`ora...inst` on member `` has experienced an unrecoverable failure.
2009-04-09 13:45:22.091: [  CRSRES][2611477408]0Human intervention required to resume its availability.
2009-04-09 13:46:25.162: [  CRSRES][2611477408]0StopResource: setting CLI values
2009-04-09 13:46:25.174: [  CRSRES][2611477408]0Attempting to stop `ora...inst` on member ``
2009-04-09 13:46:25.206: [  CRSAPP][2611477408]0StopResource error for ora...inst error code = 1

To debug SRVCTL SRVM_TRACE is set to true and a Strace is taken at OS level:

$script /tmp/srvm.log
$export SRVM_TRACE=TRUE
$srvctl start instance -d  -i
$exit

It will genertae a trace file at /tmp/srvm.log.

$ strace -aef -o /tmp/strace.log srvctl start instance -d -i

It will generate a trace file at /tmp/strace.log

— srvm.log shows follwoing error:

The SRVM trace showed that there is a problem with racgwrap script at line 62 which indicates the following:

$ORACLE_HOME/bin/racgmain “$@”

Could not found much with this line, but from the begning i.e line 1 the entry for ORACLE_HOME was missing.

ORACLE_HOME=<%ORACLE_HOME%>
export ORACLE_HOME
— Added the correct oracle_home location at this place.

Also, after checking the srvctl file for the db_home the “OHOME” and “CHOME” entries were missing:
— Added the correct entries for OHOME and CHOME ( copied the entries from the node where srvctl was working fine)

After making these two changes SRVCTL worked fine.
