Situation: As a critical link in the Output Management cooperative process, the Unicenter CA-DRAS Server application has historically produced a lot of output in the DRASLOG file. Prior to r11, this information and the available configuration options have been limited to use by administrators only. Additionally, changes required for the configuration file demanded the Unicenter CA-DRAS task be recycled in order for these changes to take effect.

Solution: Unicenter CA-DRAS r11 offers a wide range of dynamic configuration options and useful information for system administrators. Most of these options can be used, enabled, or disabled from the task manager command line, without ever needing to restart the Unicenter CA-DRAS task. For detailed information on all Unicenter CA-DRAS command utilization, please see the Unicenter CA-DRAS Installation and Operation Guide.

Some useful features for r11 include:

  • Output from an automatic Display All command occurs at startup to show all of the important configuration settings and repositories in effect for the Unicenter CA-DRAS task. It can be requested at any time during the task life. This information also shows how many users are actively logged in, and the High Water Mark for the number of users logged in at one time. There are also several Display commands available for individual current configuration settings and user activity.


  • Message suppression is now available and easily configurable to suppress specific informational messages not desired on a dynamic basis. This can reduce the JES Spool output in the DRASLOG. Also, any informational or error messages that are needed can be specified for output.


  • The Set Message Echo command is now available to write any specific Unicenter CA-DRAS task generated repository messages to the system log. This can be used for system automation purposes such as when no tape drives are available for archive retrieval from the repository. A system can detect the error message being written to the log and respond accordingly.


  • If Set Logusers is 'ON' any messages not being suppressed that are making process requests to the data repository will show the UserID in addition to the machine name from the client request. This new feature allows for tracking individual user requests in real time and is valuable for administrative and troubleshooting purposes.


  • The List Users command is available to generate the number of users logged in and provide a list of their UserIDs. This is generated at the time of each command in the SYSPRINT output DSN of the task.


  • The Set Longwait command is a new feature which allows 'timeout' cleanup of user resources being used, after the set number of minutes has passed since any activity registered for the user. The user is then logged out of both the repository and the DRAS task, canceling any outstanding tasks such as Tape Recalls. This action also frees all storage areas that were being held by the user session in the task.
