Last updated on MARCH 19, 2016

Applies to:

Oracle Reports Developer - Version 10.1.2.0.2 and later
Microsoft Windows (32-bit)
***Checked for relevance on 24-Oct-2012***


Symptoms

Reports Server 10.1.2.0.2 release installed in MS Windows platform

In-Process Reports Server is no longer working, calling a report against this report server fails with :

REP-51002: Bind to Reports Server <inprocess_repserver_name> failed


in-process reports server lives in the same JVM of OC4J_BI_Forms. OC4J_BI_FORMS in opmnctl status looks alive :

"opmnctl status" command displays:
OC4J | OC4J_BI_Forms | 2264 | Alive

But OC4J~OC4J_BI_Forms~default_island~1 located in %ORACLE_HOME%\opmn\logs indicated the in-process reports server is generating following error :

07/06/08 00:01:20 REP-56097: Engine rwEng-0 callback timeout

a) The "rwdiag" is changing intermittently, sometimes it displays Reports Server name as null:

Name = null : Type = server : Host = 10GASR2


b) Next time it is re executed, it displays the correct in-process reports server name, for example, if it is rep_10gasr2_midtier, rwdiag.sh displays:

(3) Name = rep_10gasr2_midtier : Type = server : Host = 10GASR2

Changes

<in_process_repserver_name>.conf file located in %ORACLE_HOME%\reports\conf was edited and saved.
