oslevel: Error verifying cache

Troubleshooting


Problem

oslevel could fail for non-root users with the below error $ oslevel oslevel: Error verifying cache. oslevel: Use the -f flag to rebuild cache. $ oslevel -f lslpp: A system error occurred while attempting to access the Software Vital Product Data. Use local problem reporting procedures. Although this usually occurs for non-root users it could also occur root user depending on the permissions of the ODM

Cause

The cause of this is usually a modified permission in one of the ODM database files, or could be an issue with the file /usr/bin/rm_mlcache_file.

Resolving The Problem

You will need to compare the permissions on the following directories as illustrated
correct permission of following directories and files under them:

# ls -ld /etc/objrepos
drwxr-xr-x 3 root system 4096 Apr 17 14:39 /etc/objrepos
# ls -ld /usr/lib/objrepos
drwxr-xr-x 2 root system 4096 Nov 4 2015 /usr/lib/objrepos
# ls -ld /usr/share/lib/objrepos
drwxr-xr-x 2 root system 256 Nov 4 2015 /usr/share/lib/objrepos
If the above permissions are not set correctly please run chmod on the directory as below
# chmod 755 <directory>

-in the /usr/lib/objrepos folder following files:
:

-rw-r--r-- 1 root system 245760 Oct 21 13:06 history
-rw-r--r-- 1 root system 4096 Oct 21 13:06 history.vc

-rw-r--r-- 1 root system 8192 May 11 11:46 product
-rw-r--r-- 1 root system 4096 May 11 11:46 product.vc

if any of the above is not set correctly please run the below command
# chmod 644 <filename>

In addition to the above you need to check the following file
- /usr/bin/rm_mlcache_file

This file should have the below permissions
# ls -l
-r-sr-xr-x 1 root system 14530 Nov 4 2015 /usr/bin/rm_mlcache_file

If the permissions are not set correctly run the below command

# chmod 4555 /usr/bin/rm_mlcache_file

If the owner of the file is not root then run the below command

# chown root /usr/bin/rm_mlcache_file
