OTM HTTP-400 Bad Request

Some users reported HTTP-400 Bad Request errors in ERPOTMD1. Here's what was happening:

1. If the first window you open was an OTM instance, everything worked fine.

2. If you started E-Business Suite and then accessed OTM, HTTP-400 Bad Request would result.

3. This was happening in IE8, Firefox6.

4. Apache error.log showed:

[Wed Aug 24 14:41:43 2011] [error] [client 3.75.208.77] request failed: error reading the headers


I googled and found this:

http://allthingsunix.inside.quest.com/thread.jspa?threadID=4667

This post advised:

request headers can be quite long, try setting

LimitRequestFieldsize 12392


in the server context.

See http://httpd.apache.org/docs/2.2/mod/core.html#limitrequestfieldsize

So I checked the value of this variable in Apache httpd.conf and found that it was set to:

LimitRequestFieldSize 2048
LimitRequestLine 4096


I changed it to

LimitRequestFieldSize 20480
LimitRequestLine 40960


And bounced Apache and Weblogic.

Problem was resolved. For official confirmation from Oracle about this fix, I logged SR. Oracle OTM Development was ok with this change.

adgendbc.sh java.sql.SQLException: Invalid number format for port number

Bimal asked me about this one. While running adconfig on an R12 clone, the following error was being reported:

Unique constraint error (00001) is OK if key already exists

Creating the DBC file...

We noticed the blank CONNECT_DATA and did node cleanup and re-ran autoconfig. However it still failed:

After a lot of searching in My Oracle Support I found this article: Adgendbc Fails With Database Connection Failure [ID 1302708.1]. It asked us to do this:

The following change to the database parameters allows Autoconfig, and specifically adgenfbc.sh, to complete successfully. Please make this change and then re-run autoconfig.

alter system set JAVA_JIT_ENABLED= FALSE scope = both;

We did this, but the error still appeared.

So we bounced the database. After bouncing the database it worked fine:


$ cd $INST_TOP/admin/install
$ ./adgendbc.sh
