ccmdb pack

The ccmdb pack command dumps database contents to a single, portable file.

Synopsis

ccmdb pack   database_path [-t|-to packfile|archive_device|-]
             [-z compress_level]

Uses

Use the ccmdb pack command to dump the contents of a database to a single, portable file, appropriate for moving to another system. Packed files have the extension .cpk.

To use this command, you must be logged on to the UNIX machine that hosts the Informix® server.

Note: The ccmdb backup and ccmdb pack commands archive information from the metadata and file systems of the database. They do not back up work areas. Users with copy-based work areas must reconcile changes before the administrator runs the backup. If you do not do so, changes to work areas must be backed up separately.

You can move a database from a UNIX server to a Windows server by packing the database using the ccmdb pack command, and vice versa. However, you must run ccmdb upgrade -w after moving from Windows to UNIX.

The database is locked while a pack is in progress, which prevents users from changing data in the Rational® Synergy database during a pack. Users who attempt to start a session while the pack is in progress receive a message that the database is locked.

The maximum size of a pack file produced by ccmdb pack is limited by the destination file system.

You must be user ccm_root to run this command.

Options and arguments

database_path
Specifies the path to the database you are packing.
-t|-to packfile|archive_device|-
Specifies the destination of the database pack file. The packfile argument is the name of the database packed, portable file. By default, the dump file is written to the database_name.cpk file in the current directory. The archive_device argument causes the pack file to be written to the specified archive device. Also, the "-" argument causes the pack file to be written to standard output.
-z compress_level
Specifies the level of compression of the packed file. Values range from 1 (the least—but fastest—compression) to 9 (the most—but slowest—compression). The default setting is 6.

Example

Generate a pack file called test_ccm.cpk in the /vol/bulldog/ccmdb directory.

$ ccmdb pack /vol/bulldog/ccmdb/test.ccm -to /vol/hydra/ccmdb/test_ccm.cpk

Attention

Use the ccmdb backup command for scheduled backups.
