● JDBC API calls called by the JDBC application ● JDBC API call parameters ● Executed SQL statements and their results The location of the trace file is determined by the trace options. Tracing via GUI You can start tracing by running the tracing configuration tool that includes a graphical user interface (GUI). Tracing via the GUI enables you to start and configure tracing without stopping and restarting your application that is connected via JDBC. 1. On the client, enter the following command on the command line: java -jar \ngdbc.jar. 2. Select Trace enabled. 3. Select and modify the tracing options. 4. Select OK. Tracing via Command Line You can start tracing by running the tracing configuration tool and sending commands via the command line. Tracing via the command line enables you to start and configure tracing without stopping and restarting your application that is connected via JDBC. 1. Display the current configuration by running the command java -jar \ngdbc.jar. 2. Select trace options by running the command java -jar \ngdbc.jar . 3. Start tracing by running the command java -jar \ngdbc.jar TRACE ON. Related Links Trace Options Tracing via Connection String You can start tracing by adding an option in the connection string when creating a JDBC connection. Tracing via the connection string requires you to stop and restart your application that is making the JDBC connection. Also, with the connection string, you cannot turn off tracing or set any options except setting the trace filename. Add the trace option to the connection when creating a JDBC connection. Here is an example connection string that starts tracing: jdbc:sap://localhost:30015/?autocommit=false&trace=traceFile.txt The location of the trace file is determined by the trace options. Trace Options Options when enabling JDBC tracing. 360 P U B L I C © 2012 SAP AG. All rights reserved. SAP HANA Developer Guide Using Database Client Interfaces
The first column shows the field name in the GUI-based tracing configuration tool, and the second column shows the command to enter when using the command-line tool. Table 16: Trace Options Option Command Line Option Description Trace enabled TRACE ON | OFF Starts and stops tracing Trace file folder No command-line option. The folder can be specified with the FILENAME option. Sets the directory where the system writes the trace files. When no folder is specified, the files are saved in the working directory of the application. Trace file name TRACE FILENAME [] Sets the name of the trace file. Limit file size TRACE SIZE [KB|MB|GB] To remove the size limit, use the following option: TRACE SIZE UNLIMITED Stop on error TRACE STOP ON ERROR To no longer stop on the specified error, use the following option: TRACE STOP ON ERROR OFF The system assigns each trace file an additional unique ID, so the file name is: _.prt The default file name is jdbctrace. Limits the size of each trace file. Stops writing the JDBC trace when the specified error code occurs. 14.2.2 Valid Java-to-SQL Conversions SAP HANA allows each Java object to be converted to specific SQL types using the JDBC method PreparedStatement.setObject or RowSet.setObject. Some conversions may fail at runtime if the value passed is invalid. SAP HANA Developer Guide Using Database Client Interfaces P U B L I C © 2012 SAP AG. All rights reserved. 361
