ISPF daemon START (S) command

The START command provides necessary settings for starting the ISPF daemon.

Use the START command to dynamically start a started task (STC). The abbreviated version of the command is the letter S.

procname: The name of the member in a procedure library used to start or stop the server. The default name used during the host configuration to start the daemon is BLZISPFD. The default name used during the host configuration to stop the daemon is BLZISPFS.
When the BLZISPFS started task is started, it runs the process to bring down the BLZISPFD started task, cleaning up any daemon connections. After connection clean up, both the BLZISPFD and BLZISPFS started tasks complete.

Note: It is important to use the BLZISPFS started task to bring the daemon down, as it ensures proper cleanup.
PORT: The port used by the ISPF daemon for the clients to connect. The default is 4152.
HOME: Path prefix and the mandatory /usr/lpp/jazz/v7.0.37.1.0 used to install IBM® Engineering Workflow Management. The default is /usr/lpp/jazz/v7.0.37.1.0.
Note: The z/OS UNIX path is case sensitive and it must be enclosed in single quotes (') to preserve lowercase characters.
CNFG: Absolute location of the configuration files stored in z/OS UNIX. The default is '/etc/jazz703710/ccm'.
Note: The z/OS UNIX path is case sensitive and it must be enclosed in single quotes (') to preserve lowercase characters.
WORK: The name of the directory where temporary files are stored. The default is '/tmp'.
Note: The z/OS UNIX path is case sensitive and it must be enclosed in single quotes (') to preserve lowercase characters.

The syntax diagram shows you how to specify a command so that the operating system can correctly interpret what you type. Read the syntax diagram beginning with the>> symbol and following the horizontal line (the main path) until you reach the>< symbol.

The following symbols are used in syntax diagrams:

Symbol: Description
>>: Marks the beginning of the syntax diagram.
>: Indicates that the syntax diagram is continued.
|: Marks the beginning and end of a fragment or part of the syntax diagram.
><: The end of the syntax diagram.

The following types of operands are used in syntax diagrams:

Required operands are displayed on the main path line:
Optional operands are displayed underneath the main path line:
Default operands are displayed over the main path line:

Operands are classified as keywords or variables:

Keywords are constants that must be provided. If the keyword appears in the syntax diagram in both uppercase and lowercase, the uppercase portion is the abbreviation for the keyword (for example, KEYword). Keywords are not case-sensitive. You can code them in uppercase or lowercase.
Variables are italicized, appear in lowercase letters, and represent names or values you supply. For example, a data set name is a variable. Variables can be case sensitive.

In the following example, the USER command is a keyword. The required variable parameter is user_id, and the optional variable parameter is password. Replace the variable parameters with your own values:

If a diagram shows a character that is not alphanumeric (such as parentheses, periods, commas, equal signs, and blank spaces), you must code the character as part of the syntax. In this example, you must code OPERAND=(001 0.001):

An arrow returning to an earlier part of the syntax main line in a group of operands means that more than one can be selected, or that a single one can be repeated:

If a diagram is longer than one line, the first line ends with a single arrowhead and the second line begins with a single arrowhead:

Some diagrams might contain syntax fragments, which serve to break up diagrams that are too long, too complex, or too repetitious. Syntax fragment names are in mixed case and are shown in the diagram and in the heading of the fragment. The fragment is placed following the main diagram:
