Variables

Variables are memory locations with a user- or system-defined name that can hold a value and be referenced in job and SMART folder definitions. A variable is resolved when its current value is retrieved from memory. Control-M resolves the variables that are used in a job definition when a job begins or completes execution, depending on the type of variable. The contents of the original job definition and variables remain unchanged.

You can use the following types of variables in SMART folder, sub-folder, and job attributes:

• User-Defined Variables: Variables that you create, name, and assign a value to.

• System Variables: Preexisting variables with static names and Control-M-assigned values.

• Variable Lists: A variable with a Control-M-defined name and user-assigned value, which references a Pool of named Pool variables A type of variable that you create in one job and can reference in subsequent jobs with the same Pool parameter. A Named Pool is a logical grouping of variables. .

You can manage variables with the following Monitoring utilities:

• ctmvar: Defines, deletes, modifies, and displays variables.

• ctmstvar: Displays the current value of a variable or function.

User-Defined Variables

User-defined variables are variables that you create by defining the variable name and assigning it a value in the job or SMART folder definitions. Before a job is submitted, Control-M resolves the variables and uses their retrieved values in the current job execution. For more information, see Adding Variables. For a description of the names and values that you can assign to user-defined variables, see Variable Names and Values.

Variable Scopes

The scope of a variable is the extent of the area in Control-M where your variables can be referenced. You can set the scope of user-defined variables when you add variables to a job, as described in Adding Variables. The following list describes the different variable scope types:

• Local: Variables are referenced by the job that they are defined in, such as messages, If-Action arguments, or a job script in succeeding executions.

• Global: Variables are referenced by any job in the current environment, on a self-hosted Control-M/Server.

• Named Pool: Variables are referenced by any job in the same Pool, which is a group of variables that share the same Pool name.

• SMART Folder: Variables are referenced by jobs and sub-folders in the SMART folder.

You can determine the scope of a variable by the prefix that is added to its name, as described in Variable Reference Syntax.

System Variables

System variables are preexisting variables with static names and Control-M-assigned values. You can reference system variables in job attributes and user-defined variable values, as described in Variable Reference Attributes and User-Defined Variables. Before a job executes, Control-M resolves the variables and uses the retrieved values in the current job execution.

You can reference the following system variable types in job attributes and user-defined variable values:

• Job General System Variables: Reflects attributes defined in a job definition.

• Job Scheduling System Variables: Reflects the scheduling of a job.

• Environment System Variables: Reflects your environment and are not specific to a job.

• Action System Variables: Returns statistics about your job after it has been executed.

Variable Lists

A variable list is a variable with a Control-M-assigned name, such as POOLSYM, and a user-defined value. Variable lists enable you to define up to 1,024 variables in a text file, another job, or a utility, and reference them locally or globally, without the need to manually redefine them in each job, SMART folder, or sub-folder.

You can reference a %%POOLSYM (Local) or %%\POOLSYM (Global) variable list in SMART folders, sub-folders, and jobs. POOLSYM variable lists contain a user-defined value that consists of a Pool name where one or more named Pool variables A type of variable that you create in one job and can reference in subsequent jobs with the same Pool parameter. A Named Pool is a logical grouping of variables. are defined.

Adding Variables

This procedure describes how to add user-defined variables or variable lists to a folder or job, which enables you to share data between multiple jobs.

Begin

1. From the Variables area in the job or folder definitions, click .

2. From the Type drop-down list, select one of the following variable scope types:

   • Local: Defines a variable that can be referenced by the job or folder that they are defined in.

   • Global: Defines a variable that can be referenced by any job or folder in the current environment.

   • Named Pool: Defines a variable that can be referenced by referring to the Pool name.

     In the Pool Name field that appears, type a logical Pool name.

   • SMART Folder: Defines a variable that can be referenced by all jobs and sub-folders in the SMART folder.

3. In the Name field, do one of the following:

   • User-Defined Variable: Type a logical variable name.

   • Variable List: Do the following:

     • POOLSYM: Type POOLSYM.

4. In the Value field, do one of the following:

   • User-Defined Variable: Type the variable value.

   • Variable List: Do the following:

     • POOLSYM: Type the Pool name.

   A variable is added to the job definition.

   To resolve and view the current values of your variables, see Variables.

Variable Simulation

Variable Simulation enables you to view the original and resolved values of variables in your SMART folder, sub-folder, or job, without the need to run any of them.

In an OS job, you can toggle back and forth between variable simulations in the Command field and Variables area of an OS job, all within the same Variable Simulation pane. This eliminates the need to close the Variable Simulation pane in one area of the job definitions and reopen it from another.

The following procedures describe how to simulate variables:

• Simulating Added Variables

• Simulating Variables in OS Jobs

Simulating Added Variables

This procedure describes how to view the original and resolved values of added variables in SMART folders, sub-folders, or jobs.

Begin

• From the top right corner of the Variables area, in the General tab, click .

  The Name, Original Value, and Resolved Value of each variable appear in the Variable Simulation pane.

  The error message CTMERR appears with the variable name in the Resolved Value when one of the following values have been assigned:

  • A nonexistent variable.

  • A user-defined variable that is assigned a value that includes a nonexistent variable.

Simulating Variables in OS Jobs

This procedure describes how to view the original and resolved values of variables in OS jobs.

Begin

• Do one of the following:

  • To simulate variables used in the Command field, click .

    The Original Command Line and Resolved Command Line appear in the Variable Simulation pane.

    The error message CTMERR appears with the variable name in the Resolved Command Line when one of the following values have been assigned:

    • A nonexistent variable.

    • A user-defined variable that is assigned a value that includes a nonexistent variable.

  • To simulate variables added in the Variables area, see Simulating Added Variables.

  You can toggle back and forth between variable simulations in the Command field and the Variables area by clicking Command Line and Variables in the Variable Simulation pane.

Shared Variables

The Shared Variables tool enables you to monitor the current and changing resolved values of all global and named Pool variables in Workspaces, SMART folders, or active jobs during run time.

where the . (period) operator concatenates the variables.

You must type .. (two periods) to add a . to the string.

A variable function performs an action or process on the variable, and is used instead of another expression, as described in each of the available functions:

• %%CALCDATE

• %%GETENV

%%CALCDATE

%%CALCDATE and %%$CALCDATE: Adds or subtracts a specified number of days from a specified date with %%CALCDATE in yymmdd format, and %%$CALCDATE in the yyyymmdd format, using the following syntax:

%%CALCDATE <DATE> <OPERATOR><NUMBER>

where:
