Database replication utility
rdm-replicate is a command-line utility to replicate data from
a source RDM database to a target RDM database.
|-h, --help||Display this usage information|
|--version||Display the version information|
|-q, --quiet||Quiet mode. No information will be displayed|
|--key=ignore||We accept this option but ignore the argument for compatibility with other rdm command line tools|
|--copy||Copy the data from the source to the target|
|-f, --force||Force overwriting a destination that exists|
|-u, --allow-unsafe||Allow skipping pack files if the target is lagging behind|
|--name=name||Specifies the server port (TCP/IP) or name (non-TCP-IP) for connections. The default port is "21553" and the default name is "21553". If a number is specified, it will be used for the TCP/IP port and the server name. If a string or invalid port number is specified, it will be used as the server name, and the TCP/IP transport will not be initialized.|
|--docroot=path||The location of the docroot directory. (See Database Storage Location)|
|--listen=interface||Enable the listener on a given interface ('
|--service=service||Enable one or more services. Supported values are: '
|--logfile=name||Log output to the specified log file|
|--log-category=category||Set the log category (this can be specified more than
once for multiple categories) - the default is
|--log-level=level||Set the log level ('
|--err-level=level||Set the log level ('
|--poll-frequency=milliseconds||Number of milliseconds to wait between each time we poll the source database for changes|
|--start||Start the server in the background and return when an initial copy is available on the target|
|--daemon||Start the server in daemon mode and return when an initial copy is available on the target|
|--stop||Stop the server|
|--query||Query the execution status of the server|
|--pack-file-size=size||The pack file size|
|--pid-file=file-name||A file name to write the process-ID to. This file will be created before the command returns and it will be deleted upon a clean termination.|
|--source-io=how||How we are doing IO for the source database in the
case we are connecting to a remote TFS on the same
machine. Possible values are '
|source-db-uri||The Source RDM Database URI|
|target-db-uri||The Target 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.
The replication is done by copying the content of pack files from a source database to a target database.
--copy option to copy the database from the source to the target.
This operation may fail if the target database already exists.
--force option can be used to override this.
The copy will contain the data that was present in the source database
at some time after this command was started but before it returned.
This utility may be cleanly terminated on some platforms by issuing SIGTERM. Issuing SIGINT will terminate the utility immediately on some platforms. There are some limitations other clients of these databases have to obey. The source database can not be opened in exclusive mode by any client, and the destination database can only be opened in read only mode.
Please note that the options '
--listen' only applies to the TFS instantiated as part of running
rdm-replicate similarly to how they would apply to
RDM database URI that connects to another server is not affected
by these options.
