rdm-vacuum
Database vacuum tool
Synopsis
rdm-vacuum [OPTION]… db-uri
Description
rdm-vacuum is a command-line utility that vacuums data in the specified RDM database for reducing the amount of disk spaced used. The typical usage would be to vacuum the database in to its smallest disk footprint, for example:
$> rdm-vacuum --all BOOKSHOP
rdm-vacuum is a command-line utility that vacuums data in the specified
RDM database for the purpose of reducing the amount of disk spaced used.
Specify one of the options '--all', '--schema', or '--table' to do
vacuuming. One pack file will be vacuumed for each invocation of
this tool. Specifying '--new-pack' or without any of the previous
options will honor those options without doing any explicit vacuuming.
Options
| -h, --help | Display this usage information |
| --version | Display the version information |
| -q, --quiet | Quiet mode. No information will be displayed |
| --key=key | Specify the encryption key for the database ([algorithm:]passcode). The valid algorithms are xor, aes128, aes192 and aes256. The AES algorithms are only available for packages that have strong encryption support. If an algorithm is not specified, the default is aes128 for strong encryption packages and xor otherwise. |
| --docroot=path | The location of the docroot directory. (See Database Storage Location) |
| -a, --all | Vacuum all the pack files. This option implies '--pack=<last-pack-ID>, '--new-pack' and '--sync'. |
| -p, --pack=ID | Vacuum pack file ID and older |
| -n, --new-pack | Force creation of a new pack file prior to vacuuming |
| -S, --sync | Sync the pack file after vacuuming |
| -s, --schema | Vacuum the schema system drawers (incompatible with first, best, and auto) |
| -t, --table=table_name | Vacuum only the specified table. Use this option more than once to vacuum multiple tables. (incompatible with first, best, and auto |
| --db-size=size | Maximum size of all pack files (in bytes) |
| --pack-file-size=size | Maximum size of a pack file (in bytes) |
| -r, --restore | Restore original database settings after vacuuming |
| --vacuum-percentage=percentage | Percentage of in use in a pack file to vacuum |
| --vacuum-chunk-size=size | The number of bytes to write to a pack in one vacuum cycle. |
| --log-level=level | Set the log level (all, error, warning, or info). The default is info. |
| db-uri | An RDM Database URI |
Short options can be combined into one string starting with a single '-'. Mandatory arguments to long options are mandatory for short options too. Long option arguments can also be specified in a separate argument.
