  TNS-00525: Insufficient privilege for operation
   Linux Error: 1: Operation not permitted

Listener failed to start. See the error message(s) above...


Cause:

1) Ensure that /tmp/.oracle or /var/tmp/.oracle directory exists.

2) Confirm that the DBA user who is trying to start the listener has adequate read and write permissions on the directory specified above. The permissions should be 777.

3) If the /tmp directory has reached full capacity, this would cause the listener to fail to write the socket files.

Solution

To implement the solution, please use the following example:

1. cd /var/tmp

2. Check the whether the .oracle directory exists:

cd .oracle

3. If the directory does not exist, request the System Administrator create the directory and set the ownership as root:root with the permissions set to 01777

mkdir /var/tmp/.oracle
chmod 01777 /var/tmp/.oracle
chown root /var/tmp/.oracle
chgrp root /var/tmp/.oracle

[oracle@DB11G2 admin]$ ls -lrtha /var/tmp/
total 12K
drwxr-xr-x. 22 root root 4.0K May  2 04:40 ..
drwxrwxrwt.  3 root root 4.0K Jun  7 08:06 .
drwxrwxrwt.  2 root root 4.0K Jun 15 09:54 .oracle

4. start listener now .

[oracle@DB11G2 network]$ cd /tmp/.oracle/
[oracle@DB11G2 .oracle]$ ls -l
total 0

If my case there were few files under /var/tmp/.oracle with privilege different from oracle . It seems someone tried to start listener from root or non-previleged
user .So remove those files & start listener again .

[oracle@DB11G2 .oracle]$ cd /var/tmp/.oracle
