Hi,

Greatings!

I want to install pegaplatform 8.8.1 on two tomcat servers sharing one Oracle DB.

Is steps below correct?

step1: install PegaPlatform to one server by executing install.sh

step2: deploy prweb.war to one server

step3: install PegaPlatform to the second server by executing install.sh

step4: deploy prweb.war to he second server

Question

  1. If duplicate primary key error will hapen?

  2. Is there any guide or manual that tells how to install/setup servers?

Hi @guolulu: I hope you are setting up multiple app layer application servers for high availability and to maintain the load for the same application. The installation should be done one time (via IUA or command line script). The installation will help to load the data base with the required data. Post that the app server configuration should be done in the required number of servers pointing to the same database.

Thanks.

Hi@ArulDevan: Thanks for your reply!

I want to build a Env with load balance, so there are two ap servers sharing one DB.

So, steps below shoud be ok?

step1: install PegaPlatform to one server by executing install.sh

step2: deploy prweb.war to one server referring PegaRULES/PegaDATA DB info in Context.xml

step3: deploy prweb.war to the second server referring the same PegaRULES/PegaDATA DB info in Context.xml

Hi @guolulu: In a high level, this is correct. When you say install pega in one server, I hope you are referring to the DB server. It is better to do the installation (install.sh) from a server which is close with the DB server because the installation will load the objects to DB (preferably DB server).

Please see installation guide to get more details on the configurations.

Please also look into the latest architecture change from PEGA where your application work load should be deployed as containers in kubernetes.

Thanks.
