When installing a database server, the setup program prompts you for the location of the Informix® chunk files. When you choose the location:
- Place the chunk files where no one can remove them. The chunk files must reside on a local disk on the database server computer.
Note: After you create a chunk file in a database server,
do not move it. If you do, the database server will no longer work, and you might lose data.
- You must use a local NTFS file system.
- In the future, you might want to expand the capacity of an existing database server. If so, you need to create additional chunk files.
By default, Rational Synergy uses the following criteria to create the initial chunk of database space (dbspace):
- 1 MB multiplied by the number of users is used for root, log, and temp dbspace (root dbspace must be at least 60 MB).
- 2 MB multiplied by the number of users is used for the initial ccm dbspace.
Note: The criteria are just a rough estimate of the initial database chunk. As a rule, generously allocate space for the
ccm dbspace because this is where all metadata is stored and where the database typically grows.
