Starting the HCD dispatcher as a started task
There is a procedure CBDQDISP provided in SYS1.PROCLIB, which you can use to start the HCD dispatcher as a started task.
You can create a new user ID or use an existing one to be associated with the task of the HCD dispatcher. This user ID has to have permission to use UNIX System Services.
After the procedure has been adapted to your installation needs, you can start it by using the start command. Start the HCD dispatcher always after the system has been IPLed. You can also start the HCD dispatcher automatically using System Automation for z/OS.
You can change the following parameters in the procedure:
- Job name
- The HCD dispatcher submits a job for each incoming remote HCD login
request. As a default, the job name of this job starts with
CBD
. If you want the job names to start with something different thanCBD
, you can specify a different string for the beginning of the job name by setting theJNP
variable. If you want the job name to contain the user ID of the remote HCD user, specify+U
and the HCD dispatcher substitutes the+U
with the requestor's user ID. You can also add a prefix to the user ID or append a string to the user ID. For example, aX+UY
for a passed user IDBMGN
would result inXBMGNY
for the beginning of the job name. Note, the HCD dispatcher does not accept more than seven digits for the beginning of a job name. Strings longer than seven digits are truncated. The HCD dispatcher generates a job name using theJNP
variable and fills it up to eight digits. If theJNP
variable contains three digits, the job name is filled up to eight digits by using parts of the port address of the HCD dispatcher and parts of the port address of the HCD client, which are started. If theJNP
variable does not have three digits, it is filled up to eight digits by using 0…9 and A…Z. - Logging information
- For special cases (debugging or better control), the HCD dispatcher can
write logging information into a data set. In this case, change the
LOG
variable. - Port
- If there is any reason to use another port than 51107 on which
the HCD dispatcher listens for incoming remote HCD login requests, you
can specify your port by setting the
PORT
variable. - Skeleton
- You can specify another skeleton to be used to start the HCD agent
by changing the
JSK
variable. - Port range
- It is possible to determine a different range for the ports chosen by the HCD dispatcher for communication with the HCD agent during start of the dispatcher. The port range used must be configured to be available and permitted to the HCD agent. Set the variables P0 and P1 to appropriate values. Note that ports bigger than 65535 are not allowed.
