The communication scanner processor (CSP) and maintenance and operator subsystem (MOSS) dump data sets, which apply only to the IBM® 3720, 3725, and 3745 Communication Controllers, are used for traces of the CSP and MOSS. To dump the CSP and MOSS microcode for problem determination, create one data set for the dump of each component. These data sets can be cataloged. The names of these data sets are defined to z/OS® Communications Server in the start procedure.
The DD statement for each dump data set defines it for the NCP utility used to dump the communication controller. The ddname must match the ddname on the CDUMPDS (for a CSP dump) or MDUMPDS (for a MOSS dump) operand of the PCCU definition statement for the appropriate NCP. z/OS Communications Server has no restrictions on the data set name.
