Installing Oracle Grid 11gR2 on Red Hat Enterprise Linux 5 

Preparation Steps• Login to virtual server tom as user grid.

• Copy linux_11gR2_grid.zip into /u01/staging.

• Unzip the file using "unzip" command:

              [grid@tom staging]$ unzip linux_11gR2_grid.zip

• Make sure the time settings on tom and jerry are in sync:

              [grid@tom ~]$ date

              Wed Jun  9 22:17:06 PDT 2010

              [grid@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"
