Unable To Get Connection Status Verified For A DAD
(Doc ID 560922.1)
Last updated on AUGUST 21, 2020
Applies to:Oracle HTTP Server - Version 126.96.36.199 to 10.1.2.3.0 [Release AS10g to AS10gR2]
Information in this document applies to any platform.
Status of DAD is showing down in AS Console, although the DAD does work.
The status of the DAD is derived by a HTTP request sent from the AS Console
to the HTTP Server in the format of http://host.domain:port/DAD_NAME/htp.p?cbuf=Test.
This can be seen by a simple test as follows.
1. From the command line, "cd $ORACLE_HOME/Apache/Apache/logs".
2. Issue the command "tail -f <latest access_log>".
example tail -f access_log.xxxxxxxxx
3. Next, in a new browser, login to AS Console, and click on HTTP Server.
Click on Administration Tab.
Click on PL/SQL Properties.
4. Immediately go back to the tail -f access_log and you should see an entry
like this. "GET /DAD-NAME/htp.p?cbuf=Test HTTP/1.1" 200 5
5. Note, that there should be one entry in the access_log for for each number of
DADs that are defined. For example, if there are three DADs configured, then
there should be three entries in the access_log.
If the above is not written to the access_log, then the request is not making it
to the Oracle HTTP Server and thus the status of the DAD will show down in
the AS Console.
