SQLDBC Trace

SQL Database Connectivity (SQLDBC) is a runtime environment for the development of database applications and database interfaces for MaxDB. Using SQLDBC, applications can access MaxDB database instances, execute SQL statements and edit data. It consists of the runtime library libSQLDBC, the software development kit SQLDBC SDK and the tool sqldbc_cons.

SQLDBC offers, among other things, a comprehensive range of trace options which can be called up using the Database or liveCache Assistant. The Tools menu contains, among other things, the SQLDBC trace tool.

Caution Caution

Traces compromise performance. Use traces only for troubleshooting and problem analysis.
