HCL DX Portal | Guidance Needed for Cluster Creation with Single DB2 Database using Wizard

Hello HCL Support Community,

I'm seeking guidance on setting up a cluster with a single DB2 database. Here's the server architecture I've built, each one separate from the others:

  1. DX NODE01
  2. DX NODE02
  3. DX DMGR
  4. DX DB2

I've not configured any profiles for NODES and DMGR, and for the DB2 server, I've only completed the basic DB2 installation without any instance. All of my machines are essentially blank slates at this point.

When I access the setup wizard at https://<ip_add>:10202/hcl/wizard/Wizard, I understand that I'll need to provide certain information to proceed. Could you guide me through the specifics of what I need to fill out, and any subsequent steps I should take?

I'm particularly interested in understanding the best practices when configuring the DB2 server as part of this cluster. Any resources or step-by-step instructions would be immensely helpful.

Thank you in advance for your assistance.

Best regards,

Hello @Largou Walid ,

as you've already started using the ConfigWizard you are on the right track. Therefore I assume that you have also at least on one node WebSphere Portal with a profile installed.

To be able to run the cluster with DB2 as a shared database the minimum you need to create on the DB2 server is a DB2 instance so that you can access the DB2 from the Portal nodes. Creating the DB2 instance gives you the hostname, port info as well as the instance user/password to connect (which is not a best practice considering hardening).

So the command to create an instance is something like:

##
## Create an OS user named db2inst1 with a password first (useradd .....) 



Create a Db2 instance


/opt/ibm/db2/${XXDB2VERSION}/instance/db2icrt -s ese -a SERVER -p 50000 -u db2inst1 db2inst1

The Wizard guides you thru the the steps to setup the databases and do the transfer. Furthermore you"ll need another VM (better 2) with an HTTP server with the WAS Plugin running on it to distribute traffic to the DX cluster.

The following link might help you with that task as well:

Please let me know if you have further qestions.

Thanks, Hermann
