Coexistence support gives you the ability to install, configure,
run, and manage more than one product on your system.
You can have the following products installed together on your system:
- WebSphere® Application Server
for z/OS®
- WebSphere ESB for z/OS
- WebSphere Process Server configured as an ESB-only
server.
Be aware of the following points when setting up your system for coexistence:
- Dependency on WebSphere Application Server
for z/OS
Because WebSphere ESB for z/OS installs on top of WebSphere Application Server
for z/OS, each server must initially
be configured with WebSphere Application Server
for z/OS and
be compliant with WebSphere Application Server
for z/OS coexistence
before installing and configuring WebSphere ESB for z/OS.
For more information, see Coexistence support as described in the WebSphere Application Server
for z/OS Information
Center.
- Version coexistence
You can have previous versions of the product
on your system at the same time. Previous versions of the product can exist
in the same LPAR or in separate LPARs.
- Installing for coexistence
The following installation scenarios
for coexistence are supported:
- WebSphere Application Server
for z/OS, WebSphere Process
Server and WebSphere ESB
coexisting where none of the products are currently installed.
- Coexisting WebSphere ESB for z/OS and WebSphere Application Server
for z/OS when WebSphere Application Server
for z/OS already
exists
