How to install multi node instance for Pega 7.2.2
We have our bench environment with two server nodes. How shall I install Pega 7.2.2 with multi node option using single Database so that both nodes are always in sync and also if one node goes down application should always run on other node? (Ex. similar to a windows cluster?)

I am using MSSQL server as DB and Apache Tomcat 8.5.11 for App server. I have configured sqljdbc connection string with port 3181 to connect to DB in setupDatabase.properties file. Other than this, I did not configure any port manually when installing PRPC (not 7222) as well. Where do I change the port config?
Thanks for detailed explanation. This surely helps. A follow up question here. We have enabled SSL connection for additional security and use the https port (443). Hence I have to use the same port for both the nodes in server.xml file. I did this and it is not showing up node 2 in SMA. Is there any other way to configure this using the same ports for tomcat?
I am bit confused with your configuration in the two servers, could you please share the Connector tag configuration from server.xml of your https of both the nodes? So that it can be more clear to understand.
If you want to use the same port 443 for both the servers then the 2 servers should be in the different machines because in the same machine the same port can't be used for two servers. Is this your question is about?
Thanks a lot Mahesh for answering my questions. I was able to install two nodes with same https port info in server.xml file. However, when I check the system settings in the platform, it does not show me the actual node name. Both Node host and Node Description shows the node id names. I changed the description to host names for each node id and saved it. But it still shows the node id's. Do you know how to change it?
Also, I have another question on SMA. I added node 1 with by selecting Local JVM Connection from the dropdown under "Please select whether SMA is connecting locally or a remove PRPC server". How to add node 2? When I selected Remote Connection or Local JVM connection, I am getting connection timed out error. Can you please help me on this?
We have installed Pega 7.1.5 on a tomcat instance on server XYZ running on HTTP port 18080.
We have now setup another tomcat instance on the same server XYZ running on HTTP port 28080, on this instance we deployed the prweb.war/prsysmgmt.war and prhelp.war and in the tomcat context.xml configured the datasource to connect to same Database as instance 1.
Now when I am trying to add the new instance as SMA Node I am unable to do so and getting the error "This node is already added , please enter another node. "

Hi, I encountered the same error that table pr4_base exists as I'm trying to do a 2nd instance installation of pega prpc.
My current environment has an existing web/app/db tier and pega has been running for several months. I'm now trying to add a 2nd note for HA on another server but am unable to proceed any further.
I've read confusing replies that the 2nd instance of PRPC installation is not required while some says to install PRPC but change the DB2 port number. But will changing the port number of the Db create a new instance of the database table?
