Database protocols

This section provides information on the VuGen database protocols, Oracle - 2 Tier and ODBC.

Database protocols overview

VuGen creates database Vuser scripts by recording all the activity between a client and a database server. The resulting script contains LRD functions that describe the database activity.

Suppose that you have a database of customer information that is accessed by customer service personnel located throughout the country. You use database Vusers to emulate the database server servicing many requests for information.

A database Vuser can:

  • Connect to the server
  • Submit an SQL query
  • Retrieve and process the information
  • Disconnect from the server

Oracle - 2 Tier protocol

Oracle 2-Tier is a protocol handling communication with Oracle Database using a standard 2-tier client/server architecture.

For supported Oracle Database versions, see Supported Protocols.

Prerequisites for recording:

32-bit applications only 32- and 64-bit applications
  • 32-/64-bit operating system
  • 32-bit Oracle client
  • 32-bit AUTs
  • 64-bit operating system
  • 32 and 64-bit Oracle client
  • 32 and/or 64-bit AUTs

ODBC protocol

ODBC (Open Database Connectivity) is a protocol providing a common interface for accessing databases.

For supported ODBC versions, see Supported Protocols.

Prerequisites for recording:

32-bit applications only 32- and 64-bit applications
  • 32-/64-bit operating system
  • 32-bit ODBC driver
  • 32-bit AUTs

For recording 32- and 64-bit AUTs:
  • 64-bit operating system
  • 64-bit ODBC driver
  • 64-bit AUTs

Replay on Linux machines requires unixODBC v.2.3.1 or later.
