Use this screen to allocate the new Disguise Control file that File-AID for IMS uses to keep track of which disguise criteria rules are associated with each object and field.
Press END (PF3) to allocate the VSAM KSDS file, or use the CANCEL command to cancel the allocation. When allocation is complete, File-AID for IMS displays a message: FILE ALLOCATED in the upper-right corner of the screen.
New VSAM Component Names
Cluster
Specify the name of the VSAM cluster to be created for the Disguise Control file. If you don’t use quotes around the name, File-AID for IMS will add your TSO ID as the prefix.
Data component LLQ
Low level qualifier for the VSAM KSDS data component. You may overtype this field if your installation uses a data component qualifier other than “.data”.
Index component LLQ
Low level qualifier for the VSAM KSDS index component. You may overtype this field if your installation uses a different index component qualifier other than “.index”.
Data component
Displays the name of the data component after allocation.
Index component
Displays the name of the index component after allocation.
Specify SMS Class Information
Storage
Specify the SMS storage class to use for the allocation of the file, or leave blank to accept the default.
Data
Specify the SMS data class to use for the allocation of the file or leave blank to accept the default. The data class controls the attributes of the file such as RECORG, KEYLEN, KEYOFF, SPACE, etc.
Management
Specify the SMS management class to use for the allocation of the file or leave blank to accept the default. The management class controls the migration, backup, and retention for the file.
Space Allocation
Specify the space allocation values for the data and index components or accept the defaults.
Volume serial
Specify the volume serial of the direct access device (disk) where the file is to be created.
Space units
Specify one of the following:
TRK - Tracks
CYL - Cylinders
K - Kilobytes
M - Megabytes
REC - Records
Primary quantity
Specify the number of space units to use for the primary allocation. For example, if you specify CYL for units, and enter 5 for primary quantity, you will be requesting 5 cylinders of disk space for the initial allocation.
Secondary quantity
Specify the secondary allocation. If the primary allocation is filled, the system will try to acquire more disk space using this quantity for the request. For example, if you requested space units of cylinders (CYL), a primary quantity of five, and a secondary quantity of ten, and then your extract filled up the initial five cylinders, the system would attempt to acquire an additional ten cylinders of space to continue the extract. If it used up that as well, the system would continue to attempt to allocate more space, in ten cylinder increments, until either sixteen total extents had been acquired, or the extract was finished.
