1. Installing Oracle Database 11gR2 Software on Red Hat Enterprise Linux 5 (RAC)

2. Preparation Steps Login to virtual server tom as user oracle. Copy linux_11gR2_database_1of2.zip and linux_11gR2_database_2of2.zip into /u01/staging. Unzip both files using "unzip" command: [grid@tom staging]$ unzip linux_11gR2_database_1of2.zip [grid@tom staging]$ unzip linux_11gR2_database_2of2.zip Make sure the time settings on tom and jerry are in sync: [oracle@tom ~]$ date Wed Jun 9 22:17:06 PDT 2010 [oracle@jerry ~]$ date Wed Jun 9 22:17:07 PDT 2010 If the time difference is more than a few seconds, the installation could fail, so you would have to adjust the time, for example: [root@tom ~]$ date +%T -s "10:13:13" [root@jerry ~]$ date +%T -s "10:13:13" Go to /u01/staging/database directory and start the installation by issuing:./runInstaller
