Unable to create Jco connection after EP system copy

[Former Member]

Hi Gurus,

We have performed EP 6.0 SP16 system copy as per the PDF SAP WAS Java 640 patch collection. After the target system installed, system is working fine. But after few days, it started giving error as "500 Internal Server error, contact system administrator" when we try to click on create or maintain Jco Destinations button. I have gone through default log find few errors but could not get proper solution. SLD is working fine.

Any help appreciated. Find below the contents from Default log file:

Hi,

have you done the post installation steps?

URL Generator

On the target system, check the settings for

the Host and Alternative Host

parameters.

System Landscape: On the target system,

delete the old system IDs that belong to the

source system. To do this, you log on to the

portal and choose System Administration

System Configuration Knowledge

Management Content Management

Global Services System Landscape

Definitions Systems Content

Management Systems.

You may need to verify you system connection to ERP/BI in system landscape.

Also, import your new .der file from new portal to ERP in transaction STRUSTSSO2
