using data definition language (DDL) or structured query language (SQL) files.
About this task
To create Apache Derby databases for schedulers, using data definition
language (DDL) or structured query language (SQL) files, use these steps.
Procedure
- Open a command-line window.
- Verify that you have administrator rights for the database system.
- Verify that the database supports Unicode (UTF-8). Otherwise,
the database does not store all characters that can be handled in Java™ code,
which results in code page conversion problems when a client uses an incompatible
code page.
- Use the ij utility supplied with the Apache Derby system to create
the database. To use ij to create a database called scheddb which
is located in /opt, for example, you would do the following:
ij.sh
ij>connect '/opt/scheddb;create=true';
ij>quit;
The embedded version of Apache Derby supports only
one local connection. If the Application Server product is running and accessing
a Apache Derby database, then any attempts to open a second connection to
the database from the command line are rejected. Note: Add a semi-colon (;)
at the end of each command. Otherwise, ij does not execute the command.
- Exit the ij utility by issuing the quit command: quit;
Results
The Apache Derby database for the scheduler service exists.
