Unique 16-byte hexadecimal identifier that includes the job name of the PowerExchange Listener.

The

cpnode

parameter value from the NETPORT statement that PowerExchange used to submit the netport job.

The

cpport

parameter value from the NETPORT statement that PowerExchange used to submit the netport job.

Current Gregorian date.

Current Julian date.

The hexadecimal address of the ECSA memory that holds the time of the latest update to the DATAMAPS file.

Use the DMX_ECSA keyword parameter to enter this substitution variable on the second line in the PARMS DD, as follows:

This parameter is optional. Include it if you use data maps caching and want to enable a netport job to initialize quickly in an environment where APF authorization is not allowed. For example, use this parameter an environment where access to IMS databases is through DL/I.

If you do not use data maps caching, this parameter is ignored.

A substitution variable for the IMS SSID.

if you specify an IMS SSID override in the PowerCenter

IMS SSID Override

session property for a source or target or in the

IMS SSID

advanced parameter for a database row test, the override value replaces the substitution variable for the session or row test.

If you do not specify an IMS SSID override but you use an ODBA data map with a BMP netport job, the IMS SSID from the data map replaces the substitution variable.

If an IMS SSID is not available from the data map or entered as an IMS SSID override, the substitution variable is replaced by a NULL value. In this case, IMS determines which IMS subsystem to access based on the load libraries specified in the netport job.

Value of the numeric counter with the length of

n

. Valid values for the length are from 1 through 7.

The PowerExchange Listener maintains a separate value for each possible numeric counter, and increases the value by one each time that numeric counter is used. For example, if netport JCL specifies %N3 in two places in the JCL, the first occurrence is assigned a value of 001 and the second occurrence is assigned a value of 002. The next netport job that references %N3 is assigned 003, and so on.

A substitution variable for the PSB name.

If you specify a PSB name override in the PowerCenter

IMS PSBNAME Override

session property for a source or target or in the PowerExchange Navigator

PSB Name

advanced parameter for a database row test, the override value replaces the substitution variable for the session or row test. By using the substitution variable with an override, you can use the same JCL and same set of NETPORT and LISTENER statements for multiple PSBs. You do not need to edit the DBMOVER statements and restart the PowerExchange Listener.

If you do not specify a PSB name override but you use an ODBA data map with a DL/I or BMP access method override, this substitution variable is replaced by the PSB name from the data map.

Also, in the netport JCL, you can allocate a database member to the netport job, which is used for accessing the required database data sets. If this database member has the same name as the PSB, you can add an INCLUDE statement in the JCL that uses the %PSBNAME variable. For example:

By using this variable with PSB overrides, you can allocate other database members to the job.

The password of the user ID that connected to the PowerExchange Listener, which at security level 2 is different from the user ID and password credentials used to start the PowerExchange Listener job. For more information, see SECURITY Statement.

If the password is greater than eight bytes, it is a passphrase. To adhere to z/OS JCL restrictions, PowerExchange processes passphrases as follows:

Socket number on which the connection to the PowerExchange Listener was made.

If the STATS statement in the DBMOVER member specifies recording to SMF, this variable is the PowerExchange task number. Otherwise, the value is 00000.

Current time, in

24-hour

clock time format.

The user ID that connected to the PowerExchange Listener.

An optional substitution variable that the sample IMSJCL member of the RUNLIB library uses to populate the PSB parameter in the DLIBATCH PROC. Enter this variable as the sixth positional parameter in the NETPORT statement in the DBMOVER member.

An optional substitution variable. Enter it as the seventh positional parameter in the NETPORT statement in the DBMOVER member.

An optional substitution variable. Enter it as the eighth positional parameter in the NETPORT statement in the DBMOVER member.

An optional substitution variable. Enter it as the ninth positional parameter in the NETPORT statement in the DBMOVER member.

An optional substitution variable. Enter it as the tenth positional parameter in the NETPORT statement in the DBMOVER member.

An optional substitution variable. Enter it as the eleventh positional parameter in the NETPORT statement in the DBMOVER member.

An optional substitution variable. Enter it as the twelfth positional parameter in the NETPORT statement in the DBMOVER member.

An optional substitution variable. Enter it as the thirteenth positional parameter in the NETPORT statement in the DBMOVER member.
