Implementing EventView Rule Sets › EventView Variables

EventView Variables

The ability to set and use EventView variables in rules lets you create dynamic rules that depend on conditions identified by other rules and EventView rule sets. That is, you use EventView variables to control rule execution.

EventView variables can be used for the following:

• To pass information and data between rules
• To obtain more information about the environment in which the rule is executing
• To record system states

EventView variables can be set on the Set Variables panel of a message rule, a timer rule, or a group rule. Here, you can set values for up to six variables. These values can be literal or you can specify a substitution variable as the source of the variable value for a message rule.

EventView variables can be used by:

• Rules, to do the following:
  • Provide a correlation key value to match on the Message Delivery panel and the Related Message Group panel.
  • Provide a value for insertion in replacement text. Replacement text specified on the Message Modification, Set Variables and Test Variables panels can include EventView variable names.
• Processes, where the macros EVVARGET and EVVARSET can be used to get and set the values of EventView variables. Variable names can be specified in the Parameters field on the Rule Action panel, as well as on other panels where processes are invoked.
• NCL procedures, where the $RECALL application program interface (API) can be used to get and set the values of EventView variables. For more information about $RECALL API, see the Reference Guide.

You must remember to add the EventView variable indicator prefix, &ZREV, to a variable name when it is specified for evaluation.
