Verifying Oracle file mapping setup

Before you enable Oracle file mapping, verify that $ORACLE_HOME and ORCLfmap

directories are properly set up.

To verify that $ORACLE_HOME is set up for Oracle file mapping (ORAMAP)

Enter:

# cd $ORACLE_HOME/rdbms/filemap/bin

# ls -l

-r-xr-x--- 1 root system 900616 Apr 08 19:16 fmputl

-r-sr-xr-x 1 root system 14614 Apr 08 19:16 fmputlhp

Verify that:

■ fmputlhp is owned by root and that the setuid bit is set.

■ The permissions for fmputlhp are set to -r-sr-xr-x.

■ The permissions for fmputl are set to -r-xr-x---.

If any of these items is not set as specified, make the appropriate corrections.

To verify the ORCLfmap direcotries are set up properly

Enter:

# cd /opt/ORCLfmap

# ls -ld prot1_32 prot1_64

Verify that both directories are owned by root and are writable only by root

(have -rwxr-xr-x permissions).

If needed, change the ownership and permissions for these directories.

Enabling Oracle file mapping

You need to explicitly enable Oracle file mapping. By default it is initially disabled.
