 localhost setroubleshoot: SELinux is preventing access to files with the label, file_t. For complete SELinux messages. run sealert -l fceaf526-a953-42bf-
bf07-82bba906b75d


[root@localhost ~]# sealert -l fceaf526-a953-42bf-bf07-82bba906b75d

Summary:

SELinux is preventing access to files with the label, file_t.

Detailed Description:

[SELinux is in permissive mode, the operation would have been denied but was
permitted due to permissive mode.]

SELinux permission checks on files labeled file_t are being denied. file_t is
the context the SELinux kernel gives to files that do not have a label. This
indicates a serious labeling problem. No files on an SELinux box should ever be
labeled file_t. If you have just added a new disk drive to the system you can
relabel it using the restorecon command. Otherwise you should relabel the entire
files system.

Allowing Access:

You can execute the following command as root to relabel your computer system:
"touch /.autorelabel; reboot"

Comment 1 Miroslav Grepl 2012-08-21 03:33:53 EDT
You will need to run 

# restorecon -R -v /u01
# chcon -R -t lib_t /u01/oracle/grid/agent11g/lib
