7.6.4 Installation Considerations<br />

7.6.4.1 <strong>CA</strong>IJGEN Macro<br />

7.6.4.2 VTAM Communications<br />

1. When specifying the optional keyword FM= on commands, you are<br />

identifying which node originally submitted the schedule or job to your<br />

local node. This optional keyword allows you to distinguish between<br />

remotely submitted schedules and jobs from locally defined and controlled<br />

schedules and jobs of the same name (that is, schedule SH001 from Cherry<br />

Hill as opposed to schedule SH001 originating in Phoenix).<br />

2. When specifying the optional keyword ROUTE= on commands you are<br />

identifying the remote node that will actually process the command you<br />

are issuing.<br />

3. When executing a command directed at a schedule at the node where that<br />

schedule is defined, all jobs within that schedule are affected.<br />

When installing <strong>Unicenter</strong> <strong>CA</strong>-<strong>Scheduler</strong>, you have to designate that you are<br />

going to be in an NJE environment.<br />

There are a set of steps you must take in establishing your communication<br />

environment. First, you must code a certain set of operands in the <strong>CA</strong>IJGEN<br />

macro <strong>for</strong> each of the data centers. Next, you must establish your VTAM<br />

network. Each of these is described separately.<br />

There are a set of operands on the <strong>CA</strong>IJGEN macro that you must consider<br />

when installing the cross-node communication facility in <strong>Unicenter</strong><br />

<strong>CA</strong>-<strong>Scheduler</strong>. They include the following.<br />

1. You must establish each of the individual locations with their own<br />

<strong>Unicenter</strong> <strong>CA</strong>-<strong>Scheduler</strong> system. Each of them must have <strong>Unicenter</strong><br />

<strong>CA</strong>-<strong>Scheduler</strong> installed and be defined to handle a <strong>Unicenter</strong> <strong>CA</strong>-<strong>Scheduler</strong><br />

NJE environment.<br />

2. You must code the parameter NJE=YES in the <strong>CA</strong>IJGEN macro. This<br />

specifies that you are going to have cross-node communications using<br />

<strong>Unicenter</strong> <strong>CA</strong>-<strong>Scheduler</strong>.<br />

3. You can override the VTAM retry interval, which means that if the VTAM<br />

connection that is suppose to exist is, <strong>for</strong> some reason, not up, then<br />

<strong>Unicenter</strong> <strong>CA</strong>-<strong>Scheduler</strong> will keep trying to make the connection every n<br />

minutes. You define n in the operand VRETRY=N in the <strong>CA</strong>IJGEN macro.<br />

You will be using VTAM as your mechanism <strong>for</strong> cross-node communications.<br />

You are going to have to do two things to implement the VTAM mechanism.<br />

1. You will have to code the <strong>CA</strong>IJNET macro as described in the <strong>Unicenter</strong><br />

<strong>CA</strong>-<strong>Scheduler</strong> Systems Programmer <strong>Guide</strong>. You must use this macro <strong>for</strong> each<br />

of the nodes in the network. Its primary purpose is to list the nodes that<br />
