Maximum Number of Rows Functions

By default, the Integration Service allows a maximum number of rows in an input block and an output block. However, you can change the maximum number of rows allowed in an output block.

Use the INFA_CTAGetInputNumRowsMax() and INFA_CTAGetOutputNumRowsMax() functions to determine the maximum number of rows in input and output blocks. Use the values these functions return to determine the buffer size if the procedure needs a buffer.

You can set the maximum number of rows in the output block using the INFA_CTASetOutputRowMax() function. You might use this function if you want the procedure to use a larger or smaller buffer.

You can only call these functions in an initialization function.

CDI-PC

provides the following functions to determine and set the maximum number of rows in blocks:

INFA_CTAGetInputNumRowsMax().
Use this function to determine the maximum number of rows allowed in an input block.

Use the following syntax:

IINT32 INFA_CTAGetInputRowMax( INFA_CT_INPUTGROUP_HANDLE inputgroup );

The following table describes the argument for this function:

Argument	Datatype	Input/ Output	Description
inputgroup	INFA_CT_INPUTGROUP_HANDLE	Input	Input group handle.

INFA_CTAGetOutputNumRowsMax().
Use this function to determine the maximum number of rows allowed in an output block.

Use the following syntax:

IINT32 INFA_CTAGetOutputRowMax( INFA_CT_OUTPUTGROUP_HANDLE outputgroup );

The following table describes the argument for this function:

Argument	Datatype	Input/ Output	Description
outputgroup	INFA_CT_OUTPUTGROUP_HANDLE	Input	Output group handle.

INFA_CTASetOutputRowMax().
Use this function to set the maximum number of rows allowed in an output block.

Use the following syntax:

INFA_STATUS INFA_CTASetOutputRowMax( INFA_CT_OUTPUTGROUP_HANDLE outputgroup, INFA_INT32 nRowMax );

The following table describes the arguments for this function:

Argument	Datatype	Input/ Output	Description
outputgroup	INFA_CT_OUTPUTGROUP_HANDLE	Input	Output group handle.
nRowMax	INFA_INT32	Input	Maximum number of rows you want to allow in an output block. You must enter a positive number. The function returns a fatal error when you use a non-positive number, including zero.
