Oracle EBS R12 – Concurrent request log and output files display with delay

We faced one issue in our Oracle EBS R12  where users reported that Concurrent request log and output files are not displaying instantly but are showing up after few seconds of delay.

Same situation was faced when trying to open any manager log files. Since log/out were opening up fine, albeit with some delay, so RRA/FNDWR setup was evidently fine.

Online Patching (ADOP) in Oracle EBS R12.2

Online patching is supported by the capability of storing multiple application editions in the database, and the provision of a dual application tier file system. At any given point in time, one of these file systems is designated as run (part of the running system) and the other as patch (either being patched or awaiting the start of the next patching cycle).

apps database login hangs after database refresh

In our EBS R12/ 11g database we have seen that apps database user login from SQLPLUS hangs after refresh.


During refresh process, after database recover/open and starting the database listener, apps login starts to hang. adconfig/ also hangs as it uses apps to connect to database
On checking alert log, there were continuous “inbound connection timed out (ORA-3136)” error.
On stopping the database listener, apps login was working fine.

Oracle EBS R12 Appslogin showing http 404

One of our EBS R12 was inaccessible and was throwing generic http-404 erorr for the login page. On the application side adopmnctl was showing status ACTIVE for all the required procesees.

Simple HTML file like http://<server_name>:<port>/OA_HTML/test.html was also not opening means it was Apache issue or Oacore issue since definition of OA_HTML in html link is given by OACORE.

Error message in the Browser was like below:

Not Found

The requested URL /OA_HTML/test.html was not found on this server.

In one of the Apache server log we were able to see that it is trying to find the file under portal directory which is not the correct place

    <MSG_TEXT>File does not exist: /fs01/<SID>/inst/apps/<CONTEXT_NAME>/portal/OA_HTML/test.html</MSG_TEXT>
