A_MSSQL_PACKETSIZE configuration variable

Restriction: This topic applies only when a Database Connectors license has been installed via the Micro Focus License Management System.

The A_MSSQL_PACKETSIZE configuration variable sets the size of network packets. Setting this variable can affect performance, since fewer and larger network calls can improve performance.

This variable must be set in the ACUFH configuration file and has no effect if set in a COBOL program via SET CONFIGURATION or SET ENVIRONMENT. The value of this variable is the largest size that the transport layer uses for network packets (although the underlying library may reduce the size specified; this is out of the control of the interface.) The largest value that can be specified is 32767. The default depends on which version of the client libraries are linked into the run time system, although 512 is the most common default.

Use this variable to tune your database performance. To set the packet size to 8192 use:

A_MSSQL_PACKETSIZE   8192

Setting this variable to 0 or to a negative value causes Database Connectors to use the default value.
