Processing an IBM MQ for z/OS dump using line mode IPCS

Use the IPCS commands to format a dump.

To format the dump using line mode IPCS commands, select the dump required by issuing the command:

SETDEF DSN('SYS1.DUMP xx ')

(where SYS1.DUMP xx is the name of the data set containing the dump). You can then use IPCS subcommands to display data from the dump.

Formatting a dump from the channel initiator on z/OS

how to format a channel initiator dump for IBM® MQ for z/OS® using line mode IPCS commands.

The IPCS VERBEXIT CSQXDPRD enables you to format a channel initiator dump. You can select the data that is formatted by specifying keywords.

Table 1 describes the keywords that you can specify with CSQXDPRD.

Table 1. Keywords for the IPCS VERBEXIT CSQXDPRD
Keyword	What is formatted
SUBSYS= `aaaa`	The control blocks of the channel initiator associated with the named subsystem. It is required for all new formatted dumps.
CHST=1, CNAM= channel name, DUMP=S\|F\|C	All channel information. The optional CNAM subparameter allows you to specify the name of a channel, up to a maximum of 20 characters, for which to format details. The optional DUMP subparameter allows you to control the extent of formatting, as follows: Specify DUMP=S (for "short") to format the first line of the hexadecimal dump of the channel data. Specify DUMP=F (for "full") to format all lines of the data. Specify DUMP=C (for "compressed᾿) to suppress the formatting of all duplicate lines in the data containing only X'00'. This is the default option
CHST=2, CNAM= channel name,	A summary of all channels, or of the channel specified by the CNAM keyword. See CHST=1 for details of the CNAM subparameter.
CHST=3, CNAM= channel name,	Data provided by CHST=2 and a program trace, line trace and formatted semaphore table print of all channels in the dump. See CHST=1 for details of the CNAM subparameter.
CLUS=1	Cluster report including the cluster repository known on the queue manager.
CLUS=2	Cluster report showing cluster registrations.
CTRACE=S\|F, DPRO= nnnnnnnn, TCB= nnnnnnn	Select either a short (CTRACE=S) or full (CTRACE=F) CTRACE. The optional DPRO subparameter allows you to specify a CTRACE for the DPRO specified. The optional TCB subparameter allows you to specify a CTRACE for the job specified.
DISP=1, DUMP=S\|F\|C	Dispatcher report See CHST=1 for details of the DUMP subparameter.
BUF=1	Buffer report
XSMF=1	Format channel initiator SMF data that is available in a dump.
