Frequently Asked Questions

Can I customise the trace output?

Andy Mc's .NET Framework FAQ
Yes. You can write your own TraceListener-derived class, and direct all output through it. Here's a simple example, which derives from TextWriterTraceListener (and therefore has in-built support for writing to files, as shown above) and adds timing information and the thread ID for each trace line: class MyListener : TextWriterTraceListener { public MyListener( Stream s ) : base(s) { } public override void WriteLine( string s ) { Writer.WriteLine( "{0:D8} [{1:D4}] {2}", Environment.

Can a larger capacitor be used to increase the time of useful light output?

Innovationhouse.com - Nightstar Frequently ASked Questions
Several capacitors were studied during the development of NightStar. NightStar currently uses a 1-Farad, 5.5V capacitor. A capacitor with an energy storage capability 3 times greater than this is also available (3.3-Farad, 5.5V). However, it would require 3 times longer to fully charge this capacitor. The 3.3. farad capacitor is also larger and would increase the size of the flashlight. See similar questions...

NS406-How do we get and install the JDBC driver for Oracle?

FAQ
We are using the type 4 JDBC driver from Oracle. You can download this driver from the Oracle website at technet.oracle.com or get it from the Oracle installation CD. Follow the instructions that come with the JDBC driver. It is fairly straight forward. We assume that the Oracle Host Server is 7.3.2 and above. See similar questions...

How can I get the output impedance of a trace?

Pericom - Frequently Asked Questions (FAQs) - By Product Fam...
The trace impedance can be controlled by the PCB layout design and the PCB manufacturer. Please refer to Application Note 32 for the calculation details. If the impedance of the trace is higher than the sum of the impedance of the driver and the series termination resistor, overshoot and undershoot will be seen at the input of the receiver on the end of the trace. See similar questions...

Which Oracle JDBC driver should I use in applets?

jGuru: Applets FAQ
Author: John Zukowski (http://www.jguru.com/guru/viewbio.jsp?EID=7) Oracle basically has two JDBC drivers: an OCI driver which includes native code and a Thin driver which is 100% Pure Java. Since the OCI driver includes native code, it cannot be used in applets. You must use thin driver. You can get all Oracle JDBC drivers from http://technet.oracle.com/software/tech/java/sqlj_jdbc/software_index.htm. See similar questions...

How do I configure an Oracle TNSNAMES.ora entry?

Ruby on Rails with Oracle FAQ
The TNSNAMES.ora file is a plain-text file used by Oracle to determine the information needed to connect to a database. You’ll typically find it within the Oracle Home /network/admin directory. Every connection includes the server name (or IP address), the port where the Oracle Listener is running, and the name of the database in view. Here’s an example of a TNS entry that might appear in the file: ORCL = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = server. See similar questions...

What options are useful to pass to 'configure'?

The most useful option is the 'prefix' option. This specifies how where you want to install KMyMoney, and should be the same location that KDE is installed. Many distro's will find this location on its own, but if it can't, you can use the command line app 'kde-config --prefix' to read out what the prefix should be. For SuSE-based distro's, /opt/kde3 is the usual location. For RedHat-based distro's, including Mandrake and Fedora Core, KDE is installed in /usr/bin. See similar questions...

How do I configure HA-JDBC to notify me when a database is deactivated?

Frequently Asked Questions
Use your logging facility. HA-JDBC generates an ERROR level log message when it automatically deactivates a database. If you use Log4J, configure an SMTP appender for the "net.sf.hajdbc" logger. The database element may contain any number of property elements. HA-JDBC will pass these properties through to the Driver.connect(String url, Properties info) method of the underlying JDBC driver. e.g. <cluster id="..." balancer="..." default-sync="..."> <database id="..

NS517-How do I configure the Naming Service to use the JDBC adaptor with DB2?

FAQ
Before making access to Db2 via JDBC, you MUST register the database using Client Configuration Assitant. The <database_name> should be the alias you specify when you register with Client Configuration Assitant. Since the database has been registered, you don't have to specify host name and port number for the vbroker.naming.url. See similar questions...

NS518-How do I configure the Naming Service to use the JDBC adaptor with Interbase?

FAQ
You should start InterServer before accessing InterBase via JDBC. If the InterBase server resides on the local host, specify server as localhost; otherwise specify it as the host name. If the InterBase database resides on NT, specify the full_db_path as Driver:\\dir1\dir2\\db.gdb (the first backslash '\' is to escape the second baskslash '\'). If the InterBase database resides on Unix, specify the full_db_path as \dir1\dir2\db.gdb. You can get more information from www.interbase.com See similar questions...

NS519-How do I configure the Naming Service to use the JDBC adaptor with MS SQL?

FAQ
The following settings in the configuration file should be modifed as follows (we assume you use jdbc driver from weblogic): See similar questions...

NS520-How do I configure the Naming Service to use the JDBC adaptor with DataExpress?

FAQ
If the JDataStore database resides on NT, the <full path of the JDataStore database> should be Driver:\\dir1\\dir2\\db.jds (the first backslash '\' is to escape the second backslash '\'). If the JDataStore database resides on UNIX, the <full path of the JDataStore database> should be /dir1/dir2/db.jds See similar questions...

How do I write information to the output window in a debug build, similar to VC6's TRACE macro?

Debugging - Windows Forms FAQs
You can use the Console.Write and Console.WriteLine methods from within a Windows Forms project to do this. The class DefaultTraceListener is used to implement this functionality. When your application is launched from Visual Studio in Debug mode, you... See similar questions...

How to match the impedance of a logic driver and its output trace?

Pericom - Frequently Asked Questions (FAQs) - By Product Fam...
The output impedance of the driver plus the series termination resistor at the output of the driver must equal the impedance of the trace: Z_out + Z_termination = Z_trace. For instance, if the Z_trace is 50-ohm and the Z_out is 20-ohm: 20 + Z_termination = 50; Z_termination = 30-ohm. Thus in order to match the impedance of the driver and the trace, we need to add a 30-ohm series termination resistor at the output of the driver. See similar questions...

Why do I need to match the impedance of a Logic driver and its output trace (transmission line)?

Pericom - Frequently Asked Questions (FAQs) - By Product Fam...
Otherwise overshoot, undershoot, or attenuation will be seen at the input of the receiver on the end of the trace. See similar questions...

How can I change output file names (e.g. TCL/Trace/Nam)?

Q
If it is not specified, the default unit is either "byte" for size or "second" for time. See similar questions...

How do I configure it?

Team Discovery TSC FAQ - dslreports.com
You configure each section (numbered 1-10) by pointing DSpy to the proper directory on your network. By putting a shortcut to DSpy in your startup folder, it will start with your TSC client during every boot/login and automatically start tracking your TSC progress. See similar questions...

What is JDBC?

SQL Developer - FAQ
JDBC (Java DataBase Connectivity) technology is an API that provides cross-database connectivity to a wide range of SQL databases and access to other tabular data sources, such as spreadsheets or flat files. With a JDBC technology-enabled driver, you can connect all corporate data even in a heterogeneous environment. Today all major databases provide JDBC drivers for access. See similar questions...
