Reports Server 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
07/06/12 17:20:51 Warning: Error reading transaction-log file
for recovery: premature end of file
07/06/12 17:20:51 Forced or abrupt (crash etc) server shutdown detected, starting recovery

Per ipm.log

07/06/14 11:02:05 [4] [libopmnoc4j] Process Ping Failed: OC4J~OC4J_BI_Forms~default_island~1

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, displays:

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


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