1) can i retrive a record from tape file by using file-aid ?
Yes , we can use FILE-AID to copy records from TAPE TO DASD.
2) On what basis we can specify the primary and secondary storage spaces in SPACE PARAMETER ?
Is it for VSAM OR FLAT files ???
VSAM -> It depends on the Control Intervals within a Control Area (CA)? and the intial load of records , lrecl of the records..
Well we have few formulaes to estimate it accurately.
3) if the space is not sufficent (primary& secondery) in the space paramerer how can we chang the primary and secondery storagy values
I am not sure what do you mean by
can we chang the primary and secondery storagy values ??
Normally we need to give more value for the secondary because it gets allocated for 16 extents.... -> its subjective to the user having access for that much space..normally user have some pre defined LIMIT ....so even if we keep increasing we may not get the required space ....
The best option in those scenarios would be to create the files on the TAPE rather than DASD.
