You need to install the database interface drivers your application requires, such as the ODBC interface and native database interfaces.
The files for the native database interfaces your application uses belong in the same directory as the application or in a directory on the system path. When you install InfoMaker, these files are installed in the Shared\PowerBuilder directory. The first two characters of the file name are PB, the next three characters identify the database, and the last two identify the version of InfoMaker. For example, PBO90125.DLL is the Oracle9i database interface and PBSYC125.DLL is the Sybase CT-LIB database interface.
