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.
