ZPWY-DDL-DUMP-INFO
ZDUMP
enables or disables memory dumping. The following values are valid:
ZDUMPFILE
specifies the name of the file that the TCP creates for its dump operation. The
following values are valid:
[\node] [.$volume] [.subvol] [.filename]
You can specify either a specific node name or \*, a generic name representing the
node on which the PATHMON process is currently running. If you do not specify a
node name, the default node for file-name expansion can be affected by the value
you specify for the ZNODEINDEPENDENT field of the TS/MP START PATHWAY
command. For more information on node independence, see the Pathway/iTS
System Management Manual.
If a file error interferes with creating a file that you specify, the TCP creates the
dump file on the same subvolume as its program object file and uses the form
ZZTCPnnx for the file name.
If you do not specify a file name, the TCP creates its dump file on the same volume
and subvolume as the PATHMON configuration file. The format of the file names
are ZZTCPnnP and ZZTCPnnB, where nn is a number from 01 to 10, and P and B
indicate the primary or the backup process, respectively, that the TCP dumped.
Reset values for each field are predefined. These values are described in Section 3,
SPI Programming Considerations. To reset the fields using the TACL program, you
must use the #SETBYTES built-in function. For more information, see the SPI
Programming Manual.
ZPWY-VAL-OFF Directs the TCP not to write data stack information to a file
when it encounters an internal or fatal error. This is the default
value.
ZPWY-VAL-ON Directs the TCP to create one or more disk files and write the
contents of its data stack and its extended data segment to
these files.
After creating 10 primary process and 10 backup process
dump files, the PATHMON process and the TCP stop
performing memory dumps. This prevents writing over
existing dump files that may indicate the original cause of a
problem, and prevents filling a disk with dump files.
