Teradata Parallel Data Pump

Chapter 5: Using INMOD and Notify Exit Routines
Overview
Programming Structure
Table 32 defines the structure by programming language for communicating between
Teradata TPump and INMOD or notify exit routines.

C
Programming Structure
First parameter:
struct {
long Status;
long RecordLength;
char buffer[xxxxx];
}
Note: In the char buffer specification, the buffer length xxxxx is:
• 32004 for Teradata for Windows
• 64004 for Teradata Database for UNIX
Second parameter:
struc
long seqnum;
short parmlen;
char parm[80];
}
In each structure, the records must be constructed so that the left-to-right order of the data
field corresponds to the order of the field names specified in the Teradata TPump LAYOUT
command and subsequent FIELD, FILLER, and TABLE commands.
Routine Entry Points
Table 33 lists the entry points for INMOD routines.

INMOD Routine Language
IBM C on z/OS platforms
z/OS platform
C on UNIX and Windows platforms
Entry Point
_dynamn
DYNAMN
_dynamn (or BLKEXIT*)
*Only for FDL-compatible INMODs compiled and linked
with BLKEXIT as the entry point. When the FDL-compatible
INMOD is used, USING(“FDLINMOD”) must be specified
in the IMPORT statement.
Table 34 lists the entry points for Notify Exit routines.
