You must define user-defined variables before you can refer to them. A maximum of 2,720 variables and variable groups can be defined in any database. When you define a variable, you give it a name, indicate if it is a simple variable or a variable group, specify its data type, and (optionally) assign it a default value and a timeout value.
Note: User-defined variables must not begin with an underscore (_ ).
Characteristics of User-Defined Variables
For each user-defined variable you can define the following characteristics:
Variable Groups
A variable group is a collection of dynamically created members that share common characteristics that you define. With these common characteristics, you create a template for each member of the variable group. The members of a variable group are created at run-time by certain actions within matched patterns. Each member has a unique name within the group and a separate value.
Case Sensitivity of Variable Names
The names of user-defined variables are always case insensitive whether or not the database is case sensitive or case insensitive. For example, you can use variable names DISKERRORS, diskerrors, and DISKerrors to refer to a variable you defined as DiskErrors.
Note: Reactivating a ClearPath Enterprise Systems OS 2200 partition which has active OS 2200 consoles associated with it will follow the procedure of deactivating and then activating the OS 2200 partition. This process will result in the loss of the retained variables maintained by the CP-AMS database activated on the OS 2200 consoles. There are a set of other circumstances under which the retained variables will be lost, some of them are: disk boot, tape boot, rehost of consoles, change of PDB file, deactivating AMS database, stopping of SPO Service on the server, failing over of SPO Server. The retained AMS variables are saved only during the normal SMC shut down and not in the case of an abrupt shut down.
