WebSphere MQ for z/OS shared channel configuration

Start the channel initiator using the command:
```
+cpf START CHINIT PARM(xparms)   (1)
```
where xparms is the name of the channel-initiator parameter module that you created.
Start an LU6.2 group listener using the command:
```
+cpf START LSTR LUNAME(G1) TRPTYPE(LU62)  INDISP(GROUP) 
```
The LUNAME of G1 refers to the symbolic name you gave your LU ((11)).
If you are using Virtual IP Addressing and wish to listen on a specific address, use the command:
```
+cpf START LSTR PORT(1555) INDISP(GROUP) IPADDR(mvsvipa) 
```

WebSphere MQ channels will not initialize successfully if the channel negotiation detects that the message sequence number is different at each end. You may need to reset this manually.

Shared channel configuration

The following sections detail the configuration to be performed on the z/OS queue manager to implement the channel described in Figure 32.

Examples are given for connecting WebSphere MQ for z/OS and MQSeries for OS/2 Warp. If you wish to connect to another WebSphere MQ product use the appropriate set of values from the table in place of those for OS/2.

Note:: The words in bold are user-specified and reflect the names of WebSphere MQ objects used throughout these examples. If you change the names used here, ensure that you also change the other references made to these objects throughout this book. All others are keywords and should be entered as shown.
