How does two phase commit process work in distributed database?
Pretty much the same way it works in any type of architecture. If it's distributed it just means it can span multiple databases of different types. Database changes required by a transaction are initially stored temporarily by each database. The transaction monitor then issues a "pre-commit" command to each database which requires an acknowledgement. If the monitor receives the appropriate response from each database, the monitor issues the "commit" command, which causes all databases to simultaneously make the transaction changes permanent.
How do you compiling a source code in java?
The javac command is used to invoke Java's compiler and compile a Java source file. A typical invocation of the javac command would look like below: javac [options] [source files] Both the [options] and the [source files] are optional parts of the command, and both allow multiple entries. The following are both legal javac commands: javac -help javac ClassName.java OneMoreClassName.java The first invocation doesn't compile any files, but prints a summary of valid options. The second invocation passes the compiler two .java files to compile (ClassName.java and OneMoreClassName.java). Whenever you specify multiple options and/or files they should be separated by spaces. This command would create the .class files that would be require to run the java progam.
In a DOS batch file how do you copy a local variable to a global variable?
1. Start line with an ENDLOCAL command. 2. Add an ampersand and a SET global = local variable. 3. Repeat step 2 for additional variables. Notes: Works vice versa with the SETLOCAL command. Works in nested arrangements of SETLOCAL and ENDLOCAL. Local and global variables can have same names. Spaces are permitted after a SETLOCAL or ENDLOCAL but might get added to a variable's value if put after a SET command so recommend avoiding spaces before the second and subsequent ampersands. Spaces are permitted but not required after the ampersand and before a SET command. The first line of this example shows where spaces are allowed, the last line shows where spaces can be omitted. SETLOCAL & SET LTEMP=%TEMP%& SET PATH=%PATH% SET LPATH=C:\BAT;%PATH% SET L1=valueL1 SET P1=valueP1 ENDLOCAL&SET G1=%L1%&SET P1=%P1%&SET PATH=%LPATH%

in every control(textbox, button, form...) there is Name property and Text property.
