While migrating discoverer sso-connections, ‘ssomig’ hangs

By | May 30th, 2010|Categories: App. Server|Tags: , , |

Helped a collegae who was migrating a discoverer configuration to another node with a different version (from 10.1.2 to 10.1.4) with now a 10.2 – infrastructure database in a separate home. The OID-users were already successfully migrated, with a little help of the example-script here, but one of the problems was that discoverer didn’t use the single-sign on. The other was that the private and public connection users had made, had disappeared.

Discoverer shows down in Grid Control while up.

Short one this time, all in favour of getting my green ‘pie’ in Grid Control management server.

Grid Control: Discoverer: 10.1.2.x
In Grid Control, after upgrade to, a Discoverer target shows down in the list, while it’s functioning quite well.

It seemed an old bug (Grid Ctrl 10.1.04) is still not […]

Sun JRE instead of Jinitiator: Discoverer

By | September 8th, 2009|Categories: App. Server|Tags: , , |

The whole company has to move in the end to Sun Java  instead of Jinitiator (also based on Sun Java by the way), so also the Discoverer – application.

Changed the client from Jinitatior 1.3.2 to Sun 5, update 6 (5.0.6).  You can download it here by the way.

As of this release you can no longer specify the exact JRE release. Only configure the ‘Family CLSID’.

Configure Discoverer, middle-tier:
1. cd $ORACLE_HOME/discoverer/config
2. backup configuration.xml
3. edit configuration.xml
4. comment out the original Sun JRE tag using the comment tags:
For example:
<!– <jvm name=”sun” classid=”clsid:CAFEEFAC-0014-0002-0006-ABCDEFFEDCBA” plugin_setup=”http://biserver.domain:7779/jpi/j2re.exe” version=”1.4.2″ versionie=”1,4,2,mn” type=”application/x-java-applet” plugin_page=”http://java.sun.com/products/archive/j2se/1.4.2_06/index.html” disco_archive=”disco5i.jarjar” d4o_archive=”d4o_double.jarjar”/> –>

5. Insert the new Sun JRE tag:
For example:
<jvm name=”sun” classid=”clsid:CAFEEFAC-0015-0000-FFFF-ABCDEFFEDCBA” plugin_setup=”http://biserver.domain:7779/jpi/jre5u16.exe” version=”1.5″ versionie=”1,5,0,mn” type=”application/x-java-applet” plugin_page=”http://java.sun.com/javase/downloads/index_jdk5.jsp” disco_archive=”disco5i.jarjar” d4o_archive=”d4o_double.jarjar”/>

Table of the Sun version versus the Family CLSID’s:

1.4.2     : clsid:CAFEEFAC-0014-0002-FFFF-ABCDEFFEDCBA
5.0        : clsid:CAFEEFAC-0015-0000-FFFF-ABCDEFFEDCBA
6.0        : clsid:CAFEEFAC-0016-0000-FFFF-ABCDEFFEDCBA

Oracle quote ———>:

“The behavior will be as follows:

If the user does not have any JRE installed on the client PC, then the JRE installed be what you have configured with the plugin_setup parameter; therefore, we would recommend that you stage the latest minor version within the JRE family.

* For 1.5, it will be 1.5.0_16 (http://java.sun.com/javase/downloads/index_jdk5.jsp).

This would require the Discoverer Administrator to:

* Download the latest jre family Windows executable you plan to use on the Windows clients
* copy or ftp (binary) the executable to the Discoverer middle-tier server at: $ORACLE_HOME/jpi/bin/
You may name it whatever you wish, for example: jre142u18.exe or jre150u16.exe
* Update the plugin_setup=”http://biserver.domain:7779/jpi/jre5u16.exe” (in the file configuration.xml), making sure the executable names match

Discoverer Plus decreased interaction-performance with Sun JRE 1.6.0_03

By | May 10th, 2009|Categories: App. Server|Tags: , |

User reported a very slow interacting on his new laptop with Discoverer Plus.  Changing tabs, opening workbook wizard e.g. Other laptops / workstation had no problems.

He was the only one who had a ‘modern’ Java version on his laptop : above 1.6.   So it had to be Java.  And that […]
