Changes

 

Cause

1) /opt/oracle/ directory does not have permissions for read and execute for the "others" OS group:


[root@1 1]# ls -ld /opt/
drwxr-xr-x 4 root root 4096 Mar 30 16:14 /opt/
[root@1 1]# ls -l /opt/
total 8
drwxr-x--- 4 root oinstall 4096 Mar 30 16:14 oracle drwxr-xr-x 3 root root 4096 Mar 30 16:14 ORCLfmap
[root@1 1]# ls -l /opt/oracle/
total 8
drwxr-x--- 2 root oinstall 4096 Mar 30 16:14 bin
drwxr-xr-x 3 root root 4096 Mar 29 11:08 extapi
[root@1 1]# ls -l /opt/oracle/extapi/
total 4
drwxr-xr-x 3 root root 4096 Mar 29 11:08 64
[root@1 1]# ls -l /opt/oracle/extapi/64/
total 4
drwxr-xr-x 3 root root 4096 Mar 29 11:08 asm
[root@1 1]# ls -l /opt/oracle/extapi/64/asm/
total 4
drwxr-xr-x 3 root root 4096 Mar 29 11:08 orcl
[root@1 1]# ls -l /opt/oracle/extapi/64/asm/orcl/
total 4
drwxr-xr-x 2 root root 4096 Mar 29 11:08 1
[root@1 1]# ls -l /opt/oracle/extapi/64/asm/orcl/1
total 20
-rwxr-xr-x 1 root root 18176 Mar 18 2009 libasm.so
[root@1 1]# ls -l /opt/oracle/extapi/64/asm/orcl/1/libasm.so
-rwxr-xr-x 1 root root 18176 Mar 18 2009 /opt/oracle/extapi/64/asm/orcl/1/libasm.so


2) Since the libasm.so is located at /opt/oracle/extapi/64/asm/orcl/1/ directory, then it cannot be read due to the read and execution permissions for the "others" OS group is closed.

Solution

Please set the in the /opt/oracle/ directory the next read and execution permissions for the "others" OS group like this:

$> ls -ld /opt/
drwxr-xr-x 4 root root 4096 Mar 30 16:14 /opt/

$> ls -l /opt/
total 8
drwxr-xr-x 4 root oinstall 4096 Mar 30 16:14 oracle
