UCM, mod_wl_ohs and http response

with one comment

Some extensive testing, “maybe” some code decompiling, and some talking to an great ACS consultant about nice error pages for UCM when using a HTTP front-end ended in this statement:

If we add “HttpSevereErrorFirstLine=HTTP/1.1 400 Bad Request” in the config.cfg and restart the Content Server, the actual error message is seen instead of the bridge error. This undocumented parameter overrides the default 503 response sent by the Content Server in case of an error to 400.

Apache complains about the bridge error when a 503 response is sent and doesn’t when it’s something like HTTP/1.1 400 Bad Request.

This feature was tested on Universal Content Manager (UCM)

hope this helps 🙂

reponse files for iam is broken

with one comment

When you run the silent install of iam with the out of the box response file you get an error:

[ERROR] Data Insufficient to start Install.
[ERROR] One and Only One of the following variables must be present

Variable Name:SKIP_SOFTWARE_UPDATES     Expected Value:true
Variable Name:SPECIFY_DOWNLOAD_LOCATION Expected Value:true
. Aborting Install

As the error shows, the response file for iam is missing the SKIP_SOFTWARE_UPDATES directive.

Just add SKIP_SOFTWARE_UPDATES=true to the .rsp file and you’re set to go.

The new file would look like this:

Response File Version=
#Provide the complete path of the Oracle Home. The Oracle Home directory name may only contain alphanumeric , hyphen (-) , dot (.) and underscore (_) characters, and it must begin with an alphanumeric character.
#Provide the complete path to a valid Middleware Home.
#Give the list of complete paths of all the valid Middleware Homes existing on the system.

Seems people start plugging their sessions for OOW 2011, so just to make sure I’m not facing an empty room here goes: This year (2011) I will be presenting on Oracle Open World together with my friend Simon Haslam. If you happen to be at OOW and fancy fusion middleware infrastructure, please come and join Simon on Monday 2 PM in Moscone South.

Title: Deployment Patterns for Oracle Fusion Middleware 11g
Time Monday, 02:00 PM, Moscone South – 310
Length 1 Hour
Abstract: Oracle Fusion Middleware 11g is a comprehensive software suite that can be installed in a wide range of different topologies. In this session, an Oracle ACE Director and an Oracle ACE combine their real-world experience in a range of organizations (including supermarkets, government departments, and banks) to explain the decisions you have to make in designing a middleware infrastructure.The presentation covers Oracle WebLogic Server, supporting infrastructure such as Oracle Internet Directory, and layered products such as Oracle SOA Suite.
