Specify one or more of the following parameters only if you want to change a particular value for the cluster from that which is found on the archive medium. If a value is given at both the cluster and component level (for example, ALLOC= and DALLOC=), the value specified at the data or index level will take precedence over the cluster value, just as IDCAMS does when you issue a DEFINE. See the IBM publication Access Method Services Reference for a more complete description of the following parameters.
This parameter allocates space for the cluster by type, primary amount and secondary amount. The format is ALLOC=(TYP,PA,SA)
Where:
TYP CYL (cylinders), TRK (tracks), or REC (records)
PA Primary allocation amount — must be from 1 to 99999999
SA Secondary allocation amount — must be from 0 to 99999999
Specify the percent of space to be left free in control intervals and control areas. Valid values are from 0 through 100, inclusively. The format is FREESPACE=(CI-percent, CA-percent)
Specify the average and maximum record size in bytes. The format is RECSZ=(AVE,MAX).
Where:
AVE Average record size.
MAX Maximum record size. If left blank, the average record size is assumed to also be the maximum.
Specify the amount of buffer space to be provided in bytes. The largest amount is 99999. If a value of 0 is specified, Access Method Services will calculate a new buffer space based on data and index control interval size.
Specify the size of the control interval. The largest CI size is 32768. If this parameter is specified and BUFFERSPACE is not, CA Disk will zero out the buffer space value passed to catalog management so that a new buffer space amount can be calculated based on the new control interval size. If a value of 0 is specified, Access Method Services will calculate a new control interval size.
Caution should be used when restoring an ESDS cluster that belongs to IMS or CICS — changing the CI size on these clusters can destroy internal RBA pointers and cause corruption of the database.
If the cluster was archived in control interval image copy format, changing the control interval size will result in a record length insert error when restoring the cluster. This parameter should not be used in that case.
Specify the new master level password to be assigned to the cluster or alternate index.
Specify the new control interval level password to be assigned to the cluster or alternate index.
Specify the new update level password to be assigned to the cluster or alternate index.
Specify the new read level password to be assigned to the cluster or alternate index.
Specify the number of attempts (0 to 7) for entering a password.
Specify the owner ID. It is 1 to 8 alphanumeric or special characters.
Specify a list of from one to twenty volumes on which the cluster is to be allocated. Non-MVS accounts are limited to a total of five volumes.
Specify the retention period of the cluster in days. The valid range is from 0 to 9999.
Specify the expiration date in Julian format (yyddd).
Specify how the cluster can be shared among users. The format is SHROPTIONS=(CR,CS).
Where:
CR Cross-region options are 1 through 4
CS Cross-system options are 3 through 4
Specify the key length and offset in the record for a key-sequenced data set. The format is KEYS=(LN,OF).
Where:
LN Length of the key
OF Offset of the key into the record
This parameter indicates the cluster's data component is not to be overwritten with binary zeros when its catalog entry is deleted.
This parameter indicates the sequence set of the cluster is to be written with the data component.
This parameter indicates the sequence set of the cluster is not to be written with the data component.
This parameter indicates the volume(s) are to be used in the order listed.
This parameter indicates the volume(s) are to be used in any order.
This parameter indicates each index record is to be written around a track as many times as it will fit.

This parameter indicates the cluster cannot have records longer than the control interval.
This parameter indicates the data component is not to be preformatted before records are loaded.
This parameter indicates the data component is to be preformatted before records are loaded.
This parameter indicates the cluster's space allocation is to come from the volume's available space, not from a VSAM data space.
This parameter indicates the cluster's space allocation is to come from a VSAM data space on the volume.
This parameter indicates a check is to be issued after every write.
This parameter indicates a check is not to be issued after every write.
