FDDRL can be installed with IMON under any user ID (see chapter "Scope of supply of FDDRL").
The FDDRL subsystem catalog (SYSSSC.FDDRL.210) is entered in the BS2000 subsystem catalog.
The name of the syntax file (SYSSDF.FDDRL.210) is entered in the SDF parameter file. The syntax file is activated by SDF. It contains the FDDRL statements and the /START-FDDRL command.
The name of the message file (SYSMES.FDDRL.210) is entered in the MIP parameter file. The MIP parameter file is activated by MIP (Message Improvement Processing).
FDDRL parameters can be set on a system-specific basis in the SYSPAR.FDDRL.210 parameter file. If the parameter file already exists, it is not overwritten, but installed under the name SYSPAR.FDDRL.210.NEW. This ensures that any system-specific settings made for an earlier installation are retained.
FDDRL parameter
FDDRL knows the following parameters; the meaning of the parameters is described in the statement MODIFY-FDDRL-PARAMETERS Define execution parameters.
| parameter | standard value | possible values |
|---|---|---|
| TASK-LIMIT | 4 | <INTEGER_1..16> |
| RUN-PRIORITY | *STD | *STD / *OWN / <INTEGER_128..255> |
| STATUS-OUTPUT-PERIOD | 5 | <INTEGER_0..60> |
| SECURE-WAIT-TIME | 60 | *NO / <INTEGER_0..604800 seconds> |
| JOB-NAME | *STD | *STD / *SAME / <NAME_1..8> |
| PROCESS-JOBS | *BY-SUBTASKS | *BY-SUBTASKS / *BY-MAINTASK |
| RETENTION-PERIOD | 0 | <INTEGER_0..32767> |
| LOCATION | *STD | *STD / <ALPHANUM-NAME_1..8> |
| TAPE-FORMAT | *STD | *STD / *V17-FORMAT / *V16-FORMAT / *V15-FORMAT |
| REPORT-FILE | *STD | *STD / *NONE |
| MONITORING | *NO | *NO / *STD |
| KEEP-REQUESTS | 40 | <INTEGER_1..32767> / *YES |
Adapting the parameters in the FDDRL parameter file
The FDDRL parameter file shows all FDDRL parameters with their possible and default values. The character '#' introduces a comment up to the end of the line. If you want to change the default values for the parameters, remove the '#' character at the beginning of the relevant line and enter the desired parameter value.
Like the operands in the // MODIFY-FDDRL-PARAMETERS statement, the parameters can also be specified in one line.
Merge of FDDRL parameter files
You can use the merge procedure MERGE-PAR to add system specific parameter of an existing FDDRL installation to the current parameter file. Thereby current system specific parameters are added at the end of the new installed parameter file (comment lines are not added) and arev stored unter the file name SYSPAR.FDDRL.210 by default. An existing parameter file is save to the file name SYSPAR.FDDRL.210.SAV in advance.
You may call the merge procedure by the command /CALL-PROCEDURE *LIB-EL(SYSPRC.FDDRL.210,MERGE-PAR).
With Operanden PROCEDURE-PARAMETERS=*PARAMETERS(...) you may specify the following parameters:
Parameter of the procedure MERGE-PAR |
SYSPAR-NEW = *STD / <filename 1..54 without-gen-vers> ,SYSPAR-OLD = *STD / <filename 1..54 without-gen-vers> ,SYSPAR-OUT = *STD/ <filename 1..54 without-gen-vers> |
Description of procedure parameter
SYSPAR-NEW = *STD / <filename 1..54 without-gen-vers>
Specifies the new installed parameter file
SYSPAR-NEW = *STD
Standard value is:
- SYSPAR.FDDRL.210.NEW for an update installation
- SYSPAR.FDDRL.210 for a new installation
SYSPAR-OLD = *STD / <filename 1..54 without-gen-vers>
Specifies the already installed system specific parameter file
SYSPAR-OLD = *STD
Standard value is:
- SYSPAR.FDDRL.210 for an update installation
- SYSPAR.FDDRL.200 for a new installation
SYSPAR-OUT = *STD / <filename 1..54 without-gen-vers>
Specifies the new created parameter file with system specific parameters
SYSPAR-OUT = *STD
The standard value is SYSPAR.FDDRL.210 for an update installation as well as a new installation.
Emergency system and FDDRL syntaxfiles
In the emergency system for the initial installation FDDRL is already pre-installed. However, in this system, FDDRL is restricted to the RELOAD function. A smaller SDF syntax file is also installed (SYSSDF.FDDRL.210.RELOAD). This means that the emergency system can be used for restoration purposes if a disaster occurs (all disks are destroyed).
If this emergency system is to be used as a standby system for FDDRL saves (e.g. of the home pubset), the original FDDRL syntax file (SYSSDF.FDDRL.210) must be installed on this system.
