12c: Core Dump When Starting Report Server Created With Extra Space " " at the Beginning (Doc ID 2519803.1)

Last updated on AUGUST 06, 2020

Applies to:

Oracle Reports Developer - Version 12.2.1.3.0 and later
Information in this document applies to any platform.

Symptoms


The original Reports Server was created with a space in front of the Reports Server name:

For Example:

" rep_server1" and not "rep_server1":

createReportsServerInstance(instanceName=' rep_server1',machine='AdminServerMachine')

 

When attempting to start it up, the following errors are seen:

DOMAIN_HOME\bin>startComponent.cmd rep_server1

Once created though, it was not possible to successfully delete it via deleteReportsServerInstance and createReportsServerInstance did not work after that.

 

The below is seen in the DOMAIN_HOME\servers\AdminServer\logs\NodeManager.lo

...
