Using Sysplex Distributor
This example shows how to set up Sysplex Distributor to use one connection
name to connect to the queue-sharing group.
- Define a Distributed DVIPA address as follows:
- Add a DYNAMICXCF statement to the IPCONFIG. This is used for inter-image
connectivity via dynamically created XCF TCP/IP links.
- Use the VIPADYNAMIC block on each image in the Sysplex.
- On the owning image, code a VIPADEFINE statement to create the DVIPA
Then code a VIPADISTRIBUTE statement to distribute it to all other or selected
images.
- On the backup image(s), code a VIPABACKUP statement for the DVIPA address.
- If more than one channel initiator will be started on any LPAR
in the sysplex then add the SHAREPORT option for the port to be shared in
the PORT reservation list in the PROFILE data set.
See z/OS(R) CS: IP Configuration Guide and z/OS CS: IP Configuration Reference for more information.
Sysplex Distributor will balance the inbound connections between each LPAR.
If there is more than one channel initiator on an LPAR, then the use of SHAREPORT
will pass that inbound connection to the listener port with the smallest number
of connections.
