Dynamic Workload Console considerations

Dynamic Workload Console V9.5 uses WebSphere Application Server Liberty Base to handle the initial user verification. In all cases, however, it is necessary to obtain a valid corresponding RACF® user ID to be able to work with the security environment in z/OS®.

Note: You cannot control the port from which the Dynamic Workload Console server started task replies to a request from the Z connector. The response ports are randomly selected.

To optimize the thread handling between Z connector and the scheduler server, you can group console users by RACF® user ID. To define this grouping, associate a list of console users to the same RACF® user ID, by editing the TWSZOSConnConfig.properties file located in:

DWC_DATA_DIR\usr\servers\dwcServer\resources\properties

Where DWC_DATA_DIR is, by default,

%Program
     Files%\wa\DWC\

on Windows, and /opt/wa/DWC on UNIX.

In TWSZOSConnConfig.properties set the last two properties as follows:

com.ibm.tws.zconn.usr.mapping.enable=true
com.ibm.tws.zconn.usr.mapping.file=mapping_file_path\mapping_file

where mapping_file is the name of the file that contains the mapping between console user and RACF® user ID, as in the following example:

engine=zos1919 user=twsuser1,twsuser2 zosuser=zos1919user1
               user=twsuser3,twsuser4 zosuser=zos1919user2
