Software requirements

IBM i operating system

Db2 Mirror requires IBM® i 7.4 or higher.

Before beginning the setup process to configure the Db2 Mirror environment, it is best to prepare your environment by installing the latest level of PTF groups.

On the setup source node, you should install the latest level of the PTF groups listed in the table below.

Table 1. Setup source node PTF groups
PTF Group Name	PTF Group Number for IBM i 7.5
IBM i Cumulative PTF package	SF99750
Db2 Mirror PTF Group	SF99951
Db2 for IBM i PTF Group	SF99950

On the managing node, you should install the latest level of the PTF groups listed in the table below.

Table 2. Managing node PTF groups
PTF Group Name	PTF Group Number for IBM i 7.5
Db2 Mirror PTF Group	SF99951
IBM HTTP Server for i PTF Group	SF99952
Java™ PTF Group	SF99955

The latest level of PTF groups can be found in the Preventative Service Planning documentation here: https://www.ibm.com/support/pages/roadmap-ibm-i-preventive-service-planning-documentation

IBM i options and products

There are software requirements for the Db2 Mirror nodes themselves as well as specific software requirements for any node that is being used to manage the environment.

License keys

Two copies of product license keys are required for the two nodes of the Db2 Mirror pair.

Add all the license keys required for the setup copy node on the setup source node prior to the clone. The keys will be automatically applied after the clone completes.

This can be done using the ADDLICKEY command using the system serial numbers. The SERIAL parameter defaults to *LOCAL, but by specifying the serial number for the setup copy node, you can add the key on the setup source node before cloning.

For example, if the setup source node has serial 1111111 and the setup copy node is 2222222, you can run the following CL commands on the setup source node:

ADDLICKEY PRDID(5770DBM) LICTRM(V7R4M0) FEATURE(5101) SERIAL(1111111) 
   LICKEY(CB5BB1 7D91C5 B07D01) USGLMT(*NOMAX) EXPDATE('*NONE')

ADDLICKEY PRDID(5770SS1) LICTRM(V7R4M0) FEATURE(5120) SERIAL(1111111) 
   LICKEY(5C93AC 55D141 9F2501) USGLMT(*NOMAX) EXPDATE('*NONE')

ADDLICKEY PRDID(5770DBM) LICTRM(V7R4M0) FEATURE(5101) SERIAL(2222222) 
   LICKEY(B5EBC2 1869B9 AEEB01) USGLMT(*NOMAX) EXPDATE('*NONE')

ADDLICKEY PRDID(5770SS1) LICTRM(V7R4M0) FEATURE(5120) SERIAL(2222222) 
   LICKEY(9AA16D 0C1762 76C001) USGLMT(*NOMAX) EXPDATE('*NONE')

If you do not add the keys to the setup source node before the clone, you will need to manually add the license keys required for the setup copy node after the Db2 Mirror setup is complete.

For more information on how to add license keys, see Adding license key information.
