Keyword and parameter descriptions

 

You must specify a listener for which you want to display information. We can specify a listener by using either a specific listener name or a generic listener name. By using a generic listener name, we can display either:

(generic-listener-name)

The name of the listener definition for which information is to be displayed. A single asterisk (*) specifies that information for all listener identifiers is to be displayed. A character string with an asterisk at the end matches all listeners with the string followed by zero or more characters.

TRPTYPE

Transmission protocol. If you specify this parameter, it must follow directly after the generic-listener-name parameter. If you do not specify this parameter, a default of ALL is assumed. Values are:

ALL

This is the default value and displays information for all listeners.

LU62

Displays information for all listeners defined with a value of LU62 in their TRPTYPE parameter.

NETBIOS

Displays information for all listeners defined with a value of NETBIOS in their TRPTYPE parameter.

SPX

Displays information for all listeners defined with a value of SPX in their TRPTYPE parameter.

TCP

Displays information for all listeners defined with a value of TCP in their TRPTYPE parameter.

WHERE

Specify a filter condition to display information for those listeners that satisfy the selection criterion of the filter condition. The filter condition is in three parts: filter-keyword, operator, and filter-value:

filter-keyword

Any parameter that can be used to display attributes for this DISPLAY command.

operator

This is used to determine whether a listener satisfies the filter value on the given filter keyword. The operators are:

LT

Less than

GT

Greater than

EQ

Equal to

NE

Not equal to

LE

Less than or equal to

GE

Greater than or equal to

LK

Matches a generic string that you provide as a filter-value

NL

Does not match a generic string that you provide as a filter-value

filter-value

The value that the attribute value must be tested against using the operator. Depending on the filter-keyword, this can be:

  • An explicit value, that is a valid value for the attribute being tested.

  • A generic value. This is a character string. with an asterisk at the end, for example ABC*. If the operator is LK, all items where the attribute value begins with the string (ABC in the example) are listed. If the operator is NL, all items where the attribute value does not begin with the string are listed.

    We cannot use a generic filter-value for parameters with numeric values or with one of a set of values.

ALL

Specify this to display all the listener information for each specified listener. If this parameter is specified, any parameters that are requested specifically have no effect; all parameters are still displayed.

This is the default if you do not specify a generic identifier, and do not request any specific parameters.

On z/OS this is also the default if you specify a filter condition using the WHERE parameter, but on other platforms only requested attributes are displayed.
