I have an Oracle Reports server 10g ( that for the last few years has been running okay with the rwclient.sh client application residing on the same host.

Due to some performance issues caused by long running/heavy reports we are looking at trying to separate the reports server from the application server.

From memory rwserver.sh should be able to accept connections from a client on the same LAN, but not on the rwservers localhost (but I'm going back many years since I saw that sort of setup and I was just a developer, not an admin, so I could be misremembering it).

When I try and submit a report across the network I get:

dgs@local:~ $ rwclient.sh server=rep_cig userid=test/test@CIGDB report=/home/dgs/report_file/RCL16.rdf desformat=XML destype=FILE desname=/home/dgs/report_output/claims_outstanding.xml imp_comp_id=1619 

REP-0178: Cannot connect to Reports Server 'rep_cig'.

I've enabled tracing on the reports server and can see requests on the server coming from the external clients (i think), but I only get one line per report run attempt. (But consistently get this same line so I think the rwclient is at least seeing the rwserver):

 [2017/8/4 1:43:19:104] Debug 50103 (ServerPacketReceiver:handlePacket): Got a request packet

Looking at the output of netstat -tupln, there seems to be number of ports opened by the reports/java process - most of them open to, but a couple are bound to

(The java processes above are all for oracle.reports.engine.RWEngine)

I assume the multiple ports things is why the server can see the initial probe, but the client then fails to connect properly.

I suspect there's got to be an option somewhere that determines what interface the server tries to bind to but I can't find any option in the report server .conf to enable this.


  1. Is it actually even possible to connect to the reports server from external clients? and if so;
  2. Where abouts do I need to configure the reports server so it listens for external connections?
