CLSU-00100,CLSU-00101 and CLSU-00103 Errors when run “srvctl status”

In GI/RAC environment, directories and files permission should be identical on all nodes.

SYMPTOMS

When non-oracle user ran “srvctl status service -d RACTEST” on second node, get the following errors. But it did not happen on the first node.

$ srvctl status service -d RACTEST
sclsdglnam failed
path: /u01/app/oracle/product/11.2.0/dbhome_2/log/racnode2/client
filename: clsc
2016-08-31 11:57:42.820:
CLSD: An error occurred while attempting to generate a full name. Logging may not be active for this process
Additional diagnostics: CLSU-00100: Operating System function: access failed failed with error data: 13
CLSU-00101: Operating System error message: Permission denied
CLSU-00103: error location: SlfAccess
(:CLSD00183:)
category: -3
operation name: access failed
location: SlfAccess
dependent info: 13

CAUSE

There is a file/directory permission issue on the second node.

$cd $ORACLE_HOME/log
$ls -ltr
..
..
drwxr----T 3 oracle oinstall 4096 Aug 16 16:34 racnode2
$cd racnode2
$ls -l
drwxr----T 2 oracle oinstall 4096 Aug 31 09:58 client

While on node 1, the file permission is different.

$cd ORACLE_HOME/log
$ls -ltr
drwxr-xr-t 3 oracle oinstall 4096 Aug 16 14:13 racnode1
drwxr-xr-x 3 oracle oinstall 4096 Aug 20 17:10 diag 
$cd racnode1
$ls -ltr
total 4
drwxr-xr-t 2 oracle oinstall 4096 Aug 26 12:46 client

The solution is to change the directory/file permissions on node 2 to make it same as on node 1.

$cd $ORACLE_HOME/log
$chmod 1755 racnode2
$cd racnode2
$ls -ltr
total 4
drwxr----T 2 oracle oinstall 4096 Aug 31 09:58 client
$chmod 1755 client
$ ls -ltr
total 4
drwxr-xr-t 2 oracle oinstall 4096 Aug 31 09:58 client
