Installation of 2 PRPC instances- 851v on single physical server
I am trying to setup 2 tomcat instances on same physical server. However seeing issues when starting the 2nd instance while the 1st instance is running.
Attaching the log for reference.
Any suggestions are appreciated.
Thanks,
Satish

@SatishKumarL5551 One error is " Invalid configuration. Undefined stream provider end point"
Have you tried to decommission stream node from Stream landing page and adding it again?
Do you see any file access issues related exceptions in the logs? Kindly check the access permissions of the kafka folders created and make sure they have proper access.
Please take a look at the following forum posts:

@MarijeSchillern Thanks Marije for the above links. 2nd link has details for similar issue I am observing. However not sure where those ports mentioned in the link are available to update and validate-
Default ports <env name="dsm/services/stream/pyBrokerPort" value="9092" /> <env name="dsm/services/stream/pyKeeperPort" value="2181" /> <env name="dsm/services/stream/pyJmxPort" value="9999" /> <env name="dsm/services/stream/pyPort" value="7003" />
Can you advise.
Thanks,

Hi @SatishKumarL5551 I think it might be best if you log a support Incident for your question as this may need a more in-depth investigation.
Please can you provide the INC id here so that we can help track it?

@MarijeSchillern I already created an incident (INC-223443) but was suggested to post in PCC.

@SatishKumarL5551 I have checked the support incident you logged where I see that this question relates to the Personal Edition, not Enterprise Edition.
That is why you have been directed back to the forum.
The log file you have attached appears to reference jboss.
I would check other forum questions such as Configure Multiple instances prpc - websphere - (vertical stack - single server).
I am not an SME in this area but my search reveal that unless these are separate logical partitions (LPAR) you won't be able to carry this out. We have an open enhancement request for this: "Running multiple Pega 8 instances with DDS enabled..." FDBK-61361
The issue relates to the decisioning components (Cassandra and Kafka) which will have port conflicts. These cannot be bypassed with properties files (e.g. kafka server.properties file) to have kafka listen on a different port as the properties file is overwritten again after restarting the stream node. Having multiple LPARs for each Pega 8 instance is the only option
ie What is requested is not supported, reference:

I have added the link to the enhancement request to this post and will vote on it internally on your behalf.
