This article mainly explains "what to do if Oracle10g RAC runs root.sh Times wrong". Interested friends might as well take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "what to do if Oracle10g RAC runs root.sh Times wrong".

There are some considerations for configuration in this case. Otherwise, an error will be reported when executing the root.sh command:

[root@rac1 init.d] # / u01/app/oracle/product/crs/root.sh

WARNING: directory'/ u01According to an oracle is not owned by root

WARNING: directory'/ u01According to Oracle'is not owned by root

WARNING: directory'/ u01amp app' is not owned by root

WARNING: directory'/ u01' is not owned by root

Checking to see if Oracle CRS stack is already configured

Setting the permissions on OCR backup directory

Setting up NS directories

PROT-1: Failed to initialize ocrconfig

Failed to upgrade Oracle Cluster Registry configuration

There are several reasons for this problem:

(1) Bug

In this case, refer to:

Executing root.sh errors with "Failed To Upgrade Oracle Cluster Registry Configuration" [ID 466673.1]

(2) permissions of raw devices

Crwxrwxr-x 1 oracle oinstall 162, 4 Aug 22 11:19 raw4

Crwxrwxr-x 1 oracle oinstall 162, 3 Aug 22 11:19 raw3

Crw-r- 1 root oinstall 162, 1 Aug 22 14:53 raw1

Crw-r--r-- 1 oracle oinstall 162, 2 Aug 22 14:55 raw2

Permissions should be set as follows:

Chown root.oinstall / dev/raw/raw [1-2]

Chown oracle.oinstall / dev/raw/raw [3-5]

Chmod 775 / dev/raw/raw [1-2]

Chmod 775 / dev/raw/raw [3-5]

You can set it in the rules of udev, or you can add permissions to / etc/rc.d/rc.local.

(3) read and write problems of raw equipment

The problem encountered this time is mainly caused by bug (p4679769)

After downloading the patch, overwrite the clsfmt.bin file in the crs/bin directory

Clear the raw of ocr and voting disk and run. / root.sh again to return to normal
