# Fix from Metalink 740319.1

cd ASM ORACLE_HOME/bin
cp racgwrap racgwrap.orig

Modify racgwrap script to ensure the ORACLE_HOME is correct.

Change from:

ORACLE_HOME=%ORACLE_HOME%

ORACLE_BASE=%ORACLE_BASE%

To full ORACLE_HOME path e.g.

ORACLE_HOME=/opt/oracle/product/11.1.0/asm

ORACLE_BASE=/opt/oracle/product
