UNIX
To allocate an FXoto intermediate dataset using the ALC utility:
1. Log in to the system as root.
2. Enter the following command at the UNIX command line prompt:
# allocds -d devname [-n datasetname] [-f recform] [-r reclen] [-b
blocklen] [-c cylinders]
NOTE:
Enter only one value for each parameter. You can only allocate one dataset at a time.
-d devname : Specify the raw device name of the OPEN-x volume on which the dataset is being
allocated. This parameter is required and must be specified.
-n datasetname
: Specify the name of the dataset being allocated (maximum 44 characters:
A-Z, 0-9, @, #, ., \). Use uppercase letters only, and do not use any spaces or symbols other
than @, #, ., and \. This parameter is required. If not specified, ALC will return the residual
capacity (free space) on the specified volume in number of cylinders.
-r recform : Specify the record format of the dataset being allocated: F (fixed-length and
de-blocking), FB (fixed and blocking), V (variable and de-blocking), or VB (variable and blocking).
This parameter is required. If not specified, the default value of F is used.
-r reclen
: Specify the record length (decimal) of the dataset being allocated: 1 to 32760.
This parameter is required. If not specified, the default value of 4096 is used.
-b blocklen
: Specify the block length (decimal) of the dataset being allocated.
• When record format = F, block length = record length.
• When record format = FB, block length = record length × N (N = integer).
• When record format = V/VB, block length = record length + 4 or more.
This parameter is required. If not specified, the following default values are used:
• When record format = F/FB, default block length = record length.
• When record format = V/VB, default block length = record length + 4.
-c cylinders
: Specify the size of the dataset being allocated in number of cylinders (decimal).
This parameter is required. If not specified, the default value of 100 is used.
3. If the ALC allocate operation could not be started due to an error condition, the Allocate
check error
message is displayed. If the ALC allocate operation did not complete successfully,
an error message is displayed. Remove the error condition, and retry the operation. See Table
66 on page 154 for further information on errors in UNIX.
Windows Systems
To allocate an intermediate FXoto dataset using the ALC utility:
1. Log in to the system as administrator.
2. Double-click the Allocate icon to start the ALC utility and open the Allocation panel.
