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.
