what is oradiag_<user> folder?

Question

I see these in the my Linux folder hierarchy after installing the Zend Framework.

/oradiag_root/
/user/myuser/oradiag_myuser/
/user/myuser/oradiag_root/

This name reminds me of Oracle. But I did not find any official documentation about this.

I didn't install any Oracle server. What's going on here?

Answer 1

I never installed Oracle on my system and don't know why these directories kept being created, but I finally managed to stop them from reappearing. Here's how it's done.

First, head over to:

cd ~/oradiag_<username>/diag/clients/user_<username>/host_*/trace/

and then

head sqlnet.log

You should see an error message complaining about a directory not existing for r/w. For me, it was /usr/lib/log. I created the directory it was complaining about and deleted the oradiag_<username> directory, only to have it reappear later; however, the sqlnet.log file was now complaining about a different directory.

I repeated this process of creating directories a few times until the directory finally stopped appearing. In your case, the directories may be different, but here's what solved it for me:

sudo mkdir /usr/lib/log/diag/clients
sudo chmod 777 /usr/lib/log/diag/clients

Only the clients directory needs to be 777, apparently.

Now just wipe out the oradiag_<username> directories wherever they currently appear. They shouldn't pop up for you again.

In case you're curious, here's what finally ended up being written to that "missing" directory:

mike@mike-ubuntu:/usr/lib/log/diag/clients$ ll -a
total 8
drwxrwxrwx 2 root root 4096 2011-08-24 10:34 .
drwxr-xr-x 3 root root 4096 2011-08-24 10:34 ..

Brilliant.

Answer 2

These folder are created by the Oracle 11 SQL*Net if sqlnet.ora is not available or does not define the parameter ADR_BASE (see http://download.oracle.com/docs/cd/B28359_01/network.111/b28317/sqlnet.htm#BIIDEAFI).

Answer 3

There are a lot of suggestions out there, but the only one that worked for me was this.

In Oracle 11gR1 and higher, you have to add this to your sqlnet.ora file first:

DIAG_ADR_ENABLED=OFF

After that, then other log-disabling settings should work:

TRACE_LEVEL_CLIENT = OFF
TRACE_DIRECTORY_CLIENT=/dev/null
LOG_DIRECTORY_CLIENT = /dev/null
LOG_FILE_CLIENT = /dev/null
LOG_LEVEL_CLIENT = OFF

The logs that are created are for the Oracle client. The logs may show up when any program tries to access an Oracle database.

Answer 4

If you've installed the Zend Framework, it appears to create these directories.
