Installing Oracle RAC DB on RHEL5 ?

Installing Oracle RAC DB on RHEL5 ?


Go thru the following,
1] http://www.oracle.com/technology/pub/articles/smiley_rac10g_install.html
2] Oracle metalink Note: 421308.1 - Requirements For Installing Oracle10gR2 On RHEL/OEL 5 (x86_64)
3] To map the devices using udev either singlepath or multipath.
NOTE:465001.1 - Configuring raw devices (singlepath) for Oracle Clusterware 10g Release 2 (10.2.0) on RHEL5/OEL5
NOTE:564580.1 - Configuring raw devices (multipath) for Oracle Clusterware 10g Release 2 (10.2.0) on RHEL5/OEL5


i have faced the following problems,


1] Configuring ssh for the first time works fine. If any changes done ( Eg: i changed the home path of oracle user),
then the ssh configuration will prompt for password no matter how many times you reconfigure the ssh.
i have created another OS user orclusr instead of oracle. If any one finds a solution, please reply back.
2] i have commented the localhost entry in the /etc/hosts for the xmanager to work.
3] use runisntaller -ignoreSysPrereqs
4] You will not face much problems in single patching, but in multi pathing while installing
crs (during root.sh), it will say the crs upgrade fails, it is an oracle bug Bug.4679769. apply the patch, it will copy new executable.
5] The vipca will fail because of the oracle bug refer NOTE:414163.1 , comment out or unset the LD_ASSUME_KERNEL in vipca executable.
6] During upgrade to 10.2.0.4, the local_listener error came and we have commented out that in the parameter file.
