Configuration parameters syntax

The parameters in the configuration data set conform to the following rules:

  • Only one parameter is allowed on each line and can start in any position on that line.
  • Parameters must be specified in full and are not case-sensitive except for hierarchical file system (HFS) path names.
  • A line with an asterisk * in the first position is treated as a comment.
  • RSSparameters support standard z/OS ampersand-prefixed (&) variables (for example, &SYSNAME).
  • (SPE2507)You can include static and dynamic system symbols in the parameters. For more information see Support for static and dynamic system symbols.

Support for static and dynamic system symbols

(SPE2507)

System symbols act as placeholders and are replaced by substitution text (a character string) to maintain unique values in your shared parameter library definitions (accessible to multiple systems). There are two types of system symbols:

  • Static system symbol—The substitution text for these symbols are either system-defined or defined in the IEASYMxx member via the SYMDEF subcommand processing. Static system symbols are set during IPL (Initial Program Load) and do not normally change.
  • Dynamic system symbol—The substitution text for these symbols can change in real time at any point in an IPL and it is available via the IBM ASASYMBM or ASASYMBF service. You can use dynamic system symbols to build dynamic paths and file names.
Example

If you define AuditLogFileName rss.&SYSNAME..audit.D&YYMMDD..T&HHMMSS..log in your configuration member, and TSOP is your system name, it is resolved to AuditLogFileName rss.TSOP.audit.D250311.T203405.log.

Static or dynamic system symbols that you use must be defined in the "z/OS MVS Initialization and Tuning Reference" manual.

The following table lists commonly used dynamic system symbols:

Dynamic system symbolDescription
&MONMonth of the year
&DAYDay of the month
&JDAYJulian day of the year
&YR2Year in two digits
&YR4Year in four digits
&WDAYName of the day of the week
&HRHour
&MINMinute
&SECSecond
&JOBNAMEJob name of task
&HHMMSSTime of day. Use &LHHMMSS for local time.
&YYMMDDDate. Use &LYYMMDD for local date.

For more information about system symbols, see the "z/OS MVS Initialization and Tuning Reference" manual.
