Allocating FXoto Intermediate Datasets

When you perform FXoto operations using OPEN-x FMT volumes, you must allocate the intermediate
datasets before starting the file transfer operations. The ALC utility can only be used on OPEN-x
volumes that have already been formatted using the Data Exchange FMT utility.
NOTE:
FCU version 01-01-41 or later is required for the ALC utility.
NOTE:
For versions 01-01-41: The ALC utility for UNIX is a UNIX command executed from the UNIX command
line. The ALC utility for Windows systems is a GUI. The ALC utility for UNIX can only be used on
volumes formatted with the FMT utility for UNIX. The ALC utility for Windows systems can only be
used on volumes formatted with the FMT utility for Windows systems.
CAUTION:
The capacity of the intermediate dataset varies depending on block length, so remember to calculate
the required size for the intermediate dataset. When you transfer variable-length records, make sure
to take the 4-byte RL information and 4-byte BL information for each record into account.
76 Preparing for Data Exchange Operations
Any length within the extent supported by the OS. If an illegal RL is detected, Data
Exchange will return an error.
NOTE:
Data Exchange cannot process a variable-length dataset that includes a
record with no data entity (RL = 4).
For FXotm, the record length of the target dataset must be preconfigured to match
the record length of the data entities in the source file.
For VSE source and target datasets, the FCU VSE record option must be used to
specify the RL.
Standard record 0 (R0). Data Exchange cannot process tracks with nonstandard
R0.
For MVS: standard or index VTOC. For an index VTOC, Data Exchange ignores
the index and accesses the entire VTOC sequentially.
For VSE: The user must specify the RF, BL, and RL using the FCU VSE record option.
NOTE:
The FAL functions cannot be used on VSE datasets.
Direct access is not supported; must be converted to a SAM file.
