Deploying databases on read-only media

You can distribute databases on read-only media, such as a CD-ROM, as long as you run them in read-only mode or use a write file.

For more information on running databases in read-only mode, see -r server option.

To enable changes to be made to Adaptive Server Anywhere databases distributed on read-only media such as a CD-ROM, you can use a write file. The write file records changes made to a read-only database file, and is located on a read/write storage media such as a hard disk.

In this case, the database file is placed on the CD-ROM, while the write file is placed on disk. The connection is made to the write file, which maintains a transaction log file on disk.

For more information on write files, see Working with write files.
