DFS822I NO ALLOCATION FOR DDN 'IMSACB`x`' IN (CTL|DLS) ADDRESS SPACE.

Explanation
 The ACBLIB data sets must be defined in the JCL
used to start IMS. The DDNAMEs used to define ACBLIB are IMSACBA
and IMSACBB. x is either A or B, indicating the
missing JCL DD statement. DLS is included in this
message if the error was detected in the DL/I subordinate address
space. In a DL/I subordinate address space environment, both the control
region and JCL must define ACBLIB.

System action
 IMS terminates with abend 0071 or
0821.

Programmer response
 Check the JCL to ensure proper allocation
per the IMS system definition information.
