ICEIN control statements

The ICEIN data set contains your description of the processing that is to be done by the Image Copy function, the Recovery function, and the Create Image Copy function.

ICEIN is a mandatory input data set. You must specify the control statements that request a function of IMS HP Image Copy and its options.

This control data set usually resides in the input stream. However, it can also be defined as a member of a sequentially partitioned data set. The length of the ICEIN data set must be fixed at 80 bytes. BLKSIZE, if specified, must be a multiple of 80. The ICEIN data set contains one or more combinations of the following control statements:

GLOBAL
GROUP
IC/AIC
CIC/ACIC
RCV
CRC
WAIT

These control statements can be coded as shown in the following figure.

IMS HP Image Copy can perform only one function within a job step; batch image copy, concurrent image copy, database recovery, or create image copy.

The maximum number of GROUP, IC, AIC, CIC, ACIC, and CRC statements that you can specify in one job step for an IMS HP Image Copy function is 2048.

A control statement can contain uppercase alphabetic characters, numeric characters, and the following special characters:

Asterisk (*)
Comma (,)
Equal sign (=)
Parenthesis ( )
Forward slash (/)
