SYSIDMS is a parameter file used in the execution of batch jobs running in either local mode or under the central version.
SYSIDMS parameters allow you to specify physical requirements of the environment, such as DBNAME and DICTNAME and runtime directives such as activating IDMSQSAM. Additionally, there are SYSIDMS parameters for use specifically in a z/VSE environment. For example, there is a BLKSIZE parameter that allows you to override the blocksize for a file and a DEVADDR=SYS
nnn
parameter to specify a device address for a tape file.
The SYSIDMS file can be defined as a sequential disk file, or SYSIDMS parameters can be passed through the SYSIPT file. The SYSIDMS file is defined in the IDMSLBLS procedure so that parameters can be passed through SYSIPT.
SYSIDMS is referenced only in the generic JCL for the Batch Command Facility. You should include SYSIDMS parameters, as appropriate, in the JCL stream for each utility.
On VSE systems, the default block size of the intermediate work files used by the CA IDMS utilities is 6000 bytes. If an intermediate work file contains records larger than 6000 bytes, you must use SYSIDMS to override the blocksize.
For example, in the UNLOAD utility, the record size of the SYS002 file is 24 bytes plus the size of the data portion of the record occurrence. If the total is greater than 6000 bytes, you can use the following SYSIDMS parameter as an override:
FILENAME=SYS002,BLKSIZE=32767,FILETYPE=D
