Oracle Faq

Hi All,

As said in my previous article Installing Oracle 10gr2 CRS can be nightmare if proper requirements are not fulfilled. I faced a similar problem when I was Installing Oracle 10gr2 CRS on Solaris SPARC 64 bit

After Ruunning the OUI and the Orainstroot.sh script , when the root.sh was run on the first node the root.sh script failed giving the Message

Failed To Upgrade Oracle Cluster Registry Configuration

However when I checked the $ORA_CRS_HOME/log/alertnodename.log it showed the following lines

[client(1651)]CRS-1006:The OCR location /dev/rdsk/c4t0d2s0 is inaccessible.
Details in
/Oracle01/ufia/oracle/10.2.2/crs/log/haystack/client/ocrconfig_1651.log

When I checked $ORA_CRS_HOME/log/client/ocrconfig_1651.log it showed the following lines

The problem was when you are using RAW devices to configure your OCR location you must select a partition which atleast 100 Mb in size (I prefer 250 Mb) .However in solaris when you use cylinder 0 for this RAW partition then you can get the above error which was the case with me.

The explanation for this is

In Solaris when you configure OCR ( or even Voting Disk) on RAW Device you must skip first 1 MB or first few cylinders to avoid overwriting on Disk VTOC.

Hence the solution to avoid this problem is cleanup the failed CRS installation ( steps are given in my previous articles) and format the RAW partitions used for OCR and Voting Disks and avoid using cylinder 0 or first 1 MB.
