Chapter 5: Using INMOD and Notify Exit Routines<br />
Overview<br />
Table 35: <strong>Teradata</strong> T<strong>Pump</strong>-to-INMOD Status Codes (continued)<br />
Value<br />
Description<br />
4 <strong>Teradata</strong> <strong>Data</strong>base has failed, the INMOD routine should reposition to the last<br />
checkpoint, and <strong>Teradata</strong> T<strong>Pump</strong> is not expecting the INMOD routine to return a data<br />
record.<br />
Note: If the database restarts before the first checkpoint, <strong>Teradata</strong> T<strong>Pump</strong> sends entry<br />
code 5 for cleanup, and then it sends entry code 0 to re-initialize.<br />
<strong>Teradata</strong> T<strong>Pump</strong> reads the repositioning information, provided by the INMOD after a<br />
code 3, from the restart log table and returned to the INMOD in the buffer normally used<br />
for the data record.<br />
5 The <strong>Teradata</strong> T<strong>Pump</strong> job has ended and the INMOD routine should perform any<br />
required cleanup tasks.<br />
6 The INMOD should initialize and prepare to receive records.<br />
7 The next record is available for the INMOD.<br />
Table 36 explains the two status codes used by the INMOD-to-<strong>Teradata</strong> T<strong>Pump</strong> interface.<br />
Table 36: INMOD-to-<strong>Teradata</strong> T<strong>Pump</strong> Interface Status Codes<br />
Value<br />
Description<br />
0 A record is being returned as the body value for a read call (code 1).<br />
For calls other than read, a value of 0 indicates successful completion.<br />
Any nonzero<br />
value<br />
The INMOD routine is at an end-of-file condition for a read call (code 1). For calls<br />
other than read, a nonzero value indicates a processing error that terminates<br />

Length<br />
Length is the 32-bit binary value that the INMOD routine uses to specify the length, in bytes,<br />
of the data record. The INMOD routine can use a length value of zero to indicate an end-offile<br />
condition.<br />
Body<br />
Body is the area where the INMOD routine places the data record. Maximum record length is<br />
31K or 31,744 bytes for <strong>Teradata</strong> for Windows. Maximum record length for <strong>Teradata</strong> <strong>Data</strong>base<br />
for UNIX is 62K or 63,488 bytes.<br />
Sequence Number<br />
Sequence number is a 4-byte integer record counter portion of the source sequence number.<br />
Parameter List<br />
The parameter list in the second 32-bit address consists of the following:<br />
• VARCHAR specification<br />
