11i Apache v and Symbolic Links

Minding my own business

While cloning 11i environments to try to get to R12.2, I ran into this error when logging in after completing the clone:


You don’t have permission to access /OA_HTML/AppsLocalLogin.jsp on this server.

Wow that’s pretty serious looking.  What did I forget?  Bad values in the context file for ssl certs?  No.  Talking ssl over a port not allowed by our proxy server?  No.  It turns out, I got a little creative in trying to re-arrange environments (on an old 32-bit front end Oracle Linux 5 box) and I built this particular 11i front end off of a symbolic link in Linux pointing to an unused 11i disk path (which has already been converted to R12, on a 64-bit front end Oracle Linux 6 box).  Sometimes you have to do strange things in the name of expediency, and also because the guy who allocates disk from the SAN is out today.


The fix

Edit your context file in $APPL_TOP/admin, and change s_options_symlinks from Options -FollowSymLinks to Options +FollowSymLinks.  This writes to httpd.conf and httpd_pls.conf under your IAS Home.

Shut down your services, run autoconfig and restart services.

Use at your own caution, as it’s probably violating 10 different security rules, but I don’t care I am throwing this environment away within 3 days.

Fun with R12

Filed under: R12.2 — kkempf @ 2:38 pm


Some genius at Oracle decided to land a user-owned lock file in /tmp for the Weblogic admin server in R12.2.  This would be OK, except it doesn’t have any unique identifier in it such as PID, instance name, etc.  It’s just called .ovdlock.tmp.  It’s even funnier because they make it a hidden file so it’s challenging to find.  

Regardless, as a result, if you have multiple instances running on one (Linux) host with separate OS users for each, one will start just fine, while the other will say

Starting server AdminServer …
Error Starting server AdminServer: weblogic.nodemanager.NMException: Exception while starting server ‘AdminServer’

Without much other explanation…. the fix is to su and chown 777 /tmp/.ovdlock.tmp and retry on the host which wouldn’t start.  There was a Weblogic bug for this, and maybe even a fix, but I haven’t applied it because it didn’t appear to be for my version (10.3.6) of WLS.  Read about it at 1906029.1
