Hi I'm using Fedora Core 3 and Oracle 10g. Oracle seems to start up fine, but I'm getting this error whenever I try to run lsnrctl or sqlplus:

error while loading shared libraries: /usr/local/u01/app/oracle/product/10.1.0/db_1/lib/libnnz10.so: cannot restore segment prot after reloc: Permission denied

I did a search on Google and did come up with much. Has anyone seen this error before? The only thing I did to my system before this started happening was ran RedHats up2date tool.

I also attempted to reinstall Oracle 10g and I'm coming up with the same error. I checked permissions and looks like oracleinstall has the correct permissions

Did you change the umask to 022 and did you chmod 755? I would suggest that you change the mode on /oracle including all the subdirectories. You can also try to touch <file> /oracle and see if you can create a file there as your oracle user. Now that I think of it perhaps you did not run root.sh?

Hope this helps

Yes I did set the umask to 022 and chmod to 755 for $ORACLE_HOME (I made sure I used the -R recursive option). I ran root.sh when I initially installed oracle. I have had Oracle running fine for months. This was happened after I ran the redhat update tool. I install updates at least twice a week and this is the first time it has negatively impacted my system. The oracle user has permissions on the $ORACLE_HOME directory. I have no clue why I'm getting a permissions error. Has anyone run into this problem before?

Hi,

Check your other thread they are releated. I have posted there they are same thing.

I got this issue figured out. it looks like some permissions were changed after I ran redhat's update agent. First time i've ever had any issues with running the auto-update agent.

Wow! That's interesting!! Where did the permissions change (/oracle, /oracle/<SID>)? I'm just curious.

Yes, pls tell us what happened exactly cause i'm facing the same problem after a SELinux up2date...(my libmpg123.so produces the same error..)

The key is just to set selinux=permissive or disabled- rather than enforcing- in the /etc/selinux/config file.

Evidently, there was some change from Fedora 3 to 4 that caused this problem- up2date-ing Fedora 3 will break Oracle if SELinux is enabled.

Thanx a lot for the info! I'll try that when i get back home.
I just can't understand why fc3 has been working with selinux=enforcing for more than 6 months and suddenly, the latest update produces the error.
Apart from that, i really can't understand why the same file (libmpg123.so) which is used as a plugin by xmms in /usr/lib/xmms/Input is working fine but the one in /usr/lib/bmp/Input doesn't...
I guess selinux is indeed a big trouble...

I just had another update for selinux and that solved the issue.
thanx for the tip though :-)

My oracle user and group are oracle and oinstall respectively. I just ran these commands:
chown -R oracleinstall $ORACLE_HOME
chmod -R u+rwx $ORACLE_HOME

After I ran the update agent I noticed the $ORACLE_HOME/bin directory was owned by root. I have no clue why updating redhat packages would change permissions. Hope this helps!
