Show SQL Button
• Most of the GUI tools/wizards allow you to see the
actual command or SQL statement that is created as a
result of using the tool/wizard to perform an action
• This is very handy for:
– Learning SQL syntax
– Saving the statement to a file (or the Windows clipboard)
for later use
• can be later imported directly into Command Editor

Command Window
– Only on Windows. On Linux use the Linux shell
– Can be started with “db2cmd” or “db2cw” from an MS-DOS prompt
– The Command Window is also the same as the Command Line
Processor in non-interactive mode (as we will see next)

Command Line Processor (CLP)
– Available on all DB2 servers and clients
– The prompt starts with “db2 =>”

Task Center – No Tools Catalog Warning Dialog
•
•
Task Center requires that a tools catalog be created
– This catalog stores all the meta data and information about scheduled tasks
If you did not create the tools catalog when the database was created, an error
message dialog will be displayed like the one below when Task Center is launched
– In order to schedule tasks, you must first create the tools catalog
(you can do this when you schedule the first task)
Bina Nusantara University
22
Journal
• A DBA’s activity journal in online form
• You can view:
– Task History: All attempted scheduled tasks and their success
status
– Database History: A record of database activities performed
(backup, restore, REORGs, etc.)
– Message: History of messages returned by DB2 tools. This is
useful if you want to recall and compare old error messages, or if
you close a dialog box too quickly or by accident
– Notification Log: contains system-level message. Critical errors
are recorded here
