Hi I am installing Sun Cluster 3.1 and configuring two node cluster

I am installing following applications/softwares

 

OS: Solaris 10,

Oracle: 9.2.0.6 i

JBoss: 4.0.2

Sun Cluster 3.1

 

After installing sun cluster and registering Oracle HA, when I started the

resource group oracle_rg, only database is starting and not the listner.

 

I am using following commands to register oracle HA.

 

scrgadm -a -t SUNW.oracle_server

scrgadm -a -t SUNW.oracle_listener

scrgadm -a -g oracle_rg -h MFIN-SOL01,MFIN-SOL02       (Hostnames of two nods)

scrgadm -a -L -g oracle_rg -l msm (Logical Host name)

scrgadm -a -j oracle-server-1 -g oracle_rg -t SUNW.oracle_server -x ORACLE_HOME=/database/oracle/ora9206i -x Alert_log_file=/global/application/sclog/message-log -x ORACLE_SID=msmdb -x Connect_string=system/mfrug

scrgadm -a -j oracle-listener-1 -g oracle_rg -t SUNW.oracle_listener -x ORACLE_HOME=/database/oracle/ora9206i -x Alert_log_file=/global/application/sclog/message-log -x LISTENER_NAME=msmdb

 

 

To bringup the resource group

*****************************

scswitch -Z -g oracle_rg

 

********************************

-- Quorum Summary --

  Quorum votes possible:      2

  Quorum votes needed:        2

  Quorum votes present:       2

 

I observed following problems.

********************************

Whenever I reboot one node or disconnect one node from the network to test failover, other node will reboot

after coredump and will wait infinetly to start the cluster and display login prompt.

 

Is it because of "quorum vote needed=2"? How can I reduce quorum votes needed to 1 so that one node continue even if other node is down?

 

# bash-3.00# scswitch -Z -g oracle_rg

scswitch: On node MFIN-SOL01, resource group oracle_rg is online but resource oracle-listener-1 failed to start

 

 

listner.ora file has following lines.

************************************

I am able to start listner from commandline but not with resource group.

 

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS_LIST =

        (ADDRESS = (PROTOCOL = TCP)(HOST = MFIN-SOL01)(PORT = 1521))

      )

    )

  )

 

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (GLOBAL_DBNAME = msmdb)

      (ORACLE_HOME = /database/oracle/ora9206i)

      (SID_NAME = msmdb)

    )

  )

 

I also observed following messages in /var/adm/messages

*******************************************************

Method <bin/oracle_listener_start> failed on resource <oracle-listener-1> in resource group <oracle_rg> [exit code <1>, time used: 2% of timeout <300 seconds>]

 

Please advice me the workaround/corrective steps to get the listner up and running with resource group.

 

Thanks in advance for any help.
