COPY Statement Parameters

Edit online

The CKPT and REQUEUE parameters of the COPY statement also control aspects of the Checkpoint/Restart facility. The following table describes these parameters.

COPY statement parameters

Parameter	Description
CKPT	Specifies the interval IBM® Connect:Direct® uses to record checkpoint information. IBM Connect:Direct uses this CKPT value, rounded to the nearest block, in determining how many bytes to transfer before taking a checkpoint. If you do not specify the Copy statement CKPT parameter, IBM Connect:Direct uses the value specified in the CKPT initialization parameter. Specifying a value of CKPT=0K, or not specifying CKPT in the initialization parameters, disables checkpointing. Be aware of additional overhead associated with specifying too small a checkpoint interval, particularly when transferring large files.
REQUEUE	Indicates whether IBM Connect:Direct requeues Processes that end due to an ABEND, such as an Sx37, or enables any subsequent steps to run to Process termination. This parameter is only effective if checkpointing is in use. See the Connect:Direct Process Language help for more information.

Parameter

Description

CKPT

Specifies the interval IBM® Connect:Direct® uses to record checkpoint information. IBM Connect:Direct uses this CKPT value, rounded to the nearest block, in determining how many bytes to transfer before taking a checkpoint.

If you do not specify the Copy statement CKPT parameter, IBM Connect:Direct uses the value specified in the CKPT initialization parameter. Specifying a value of CKPT=0K, or not specifying CKPT in the initialization parameters, disables checkpointing. Be aware of additional overhead associated with specifying too small a checkpoint interval, particularly when transferring large files.

REQUEUE

Indicates whether IBM Connect:Direct requeues Processes that end due to an ABEND, such as an Sx37, or enables any subsequent steps to run to Process termination. This parameter is only effective if checkpointing is in use. See the Connect:Direct Process Language help for more information.
