Redirecting work to alternate workstations
The scheduler supports the redirecting of work from one workstation to another. If a workstation becomes inactive, you can specify, for each of its open intervals, an alternate workstation where work will be redirected. At any time, you can manually redirect the work to the workstation by using the MODIFYING THE CURRENT PLAN panel (option 5.5 from the main menu). This function does not apply to virtual workstations.
EQQMWSRP ------- MODIFYING A WORK STATION IN THE CURRENT PLAN -----------------
Command ===>
Enter/change data below:
Enter the O command above to modify open time intervals
Enter the V command above to vary workstation status
Work station : CPU1 Computer Automatic
Type : Computer JOB ability
Status : Active
REPORTING ATTR ===> A A automatic, S manual start and complete
C complete only or N non reporting
CONTROL ON SERVERS ===> Y Control on parallel servers, Y or N
CONTROL ON R1 ===> N Control on critical resource R1 , Y or N
CONTROL ON R2 ===> N Control on critical resource R2 , Y or N
When you select a workstation to be modified, the current status of the workstation is presented (see EQQMWSRP - Modifying a workstation in the current plan). In most cases, the workstation is active and no further explanation is required. If the workstation status has been modified manually or if an exception has occurred, status text that describes the current state is also displayed.
If you make changes on the MODIFYING A WORK STATION IN THE CURRENT PLAN panel, the changes take effect when you press PF3 (End). Press PF12 (Cancel) if you do not want to make the typed modifications.
If you need to manually change the status of a workstation, enter V from the MODIFYING A WORK STATION IN THE CURRENT PLAN panel, and the following panel is displayed.
EQQMWSVP ----- MODIFYING WORK STATION STATUS IN THE CURRENT PLAN --------------
Command ===>
Enter data below, and issue END command to change the status:
Work station : CPU1 Computer Automatic
Current Status : Active
NEW STATUS ===> _ A active, F failed
O offline
Fail/offline options :
STARTED OPERATIONS ===> _ R restart, L leave, E set to error
(Mandatory value L for SA, Dynamic and
Remote Engine work stations)
REROUTE OPERATIONS ===> _ Y to reroute, N to leave operations
(Mandatory value N for SA work stations)
ALTERNATE WS NAME ===> ____ Alternate Work station for reroute
The STARTED OPERATIONS field is always set to L for SA, dynamic, and remote engine work stations. The REROUTE OPERATIONS field is always set to N for SA work stations.
The values you enter on the MODIFYING WORK STATION STATUS IN THE CURRENT PLAN panel determine the effect on the workload. If you modify the workstation status to failed or offline, you must specify what should happen to operations that are already started on the workstation and whether HCL Workload Automation for Z should reroute operations to an alternate workstation.
- Be careful if you specify that operations are to be restarted on an alternate workstation. They might still be running on the original workstation. The scheduler does not know this. You must decide if they can be safely started on the alternate workstation. If you set them to error, you can rerun them after taking any necessary recovery actions; this is a safer option.
- When you issue END from this panel, the status change takes effect immediately, even if you subsequently issue CANCEL on panel EQQMWSRP.
- When defining your operations, you can specify that a particular operation should not be redirected under any circumstances.
EQQMWSOL - Modifying open time intervals in the CP shows how you can adjust the workstation fixed resources and parallel servers for a workstation, and specify an alternate workstation.
EQQMWSOL ---------- MODIFYING OPEN TIME INTERVALS IN THE CP - ROW 1 TO 3 OF 3 Command ===> Scroll ===> PAGE Change data in the rows, and/or enter any of the following row commands: I(nn) - Insert, R(nn),RR(nn) - Repeat, D(nn),DD - Delete Work station : CPU1 Main JES processor Control on servers : Yes Control on R1 : No Control on R2 : No Row From To Planned Modified cmd YY/MM/DD HH.MM YY/MM/DD HH.MM ps R1 R2 AltWS ps R1 R2 AltWS '' 03/03/14 00.00 03/03/14 05.59 120 99 99 20 99 99 ____ '' 03/03/14 06.00 03/03/14 17.59 120 99 99 10 99 99 CPU2 '' 03/03/14 18.00 03/03/14 23.59 120 99 99 20 99 99 ____ ******************************* BOTTOM OF DATA ***************************
You cannot use this panel to make the workstation unavailable: use the panel in EQQMWSVP - Modifying work station status in the current plan instead. In practice, setting the number of parallel servers to zero means that operations cannot run on the workstation.
If you add or modify an open interval, ensure that the begin time is the same or later than the current time, otherwise the update is not made.
- You modify the number the number of parallel servers between 18.00 and 23.59 on 03/03/14 to 25.
- You change the database to close CPU1 at 20.00 on 03/03/14.
- You extend the plan at 15.00.
The result is that the workstation stays open past 20.00, because there is a modified interval that lasts until 23.59. The scheduler considers that it is modified even if you change the number back to the original value.
