For more information on what the Record and Replay services are see this article.
What storage types does OpenSplice Record and Replay support?
The service records the data to storage xml files. These xml files can get quite large, and can be difficult to query and read. RnR Manager provides a Storage Editor that makes it easier to query, view and update this storage data. On import, the xml storage files are converted to a database file. The database can then be queried and updated. Updated data can be exported back into the OpenSplice Record and Replay service storage xml format if required
OpenSplice Record and Replay v6.4 and above supports two types of storage:
- XML – recorded data will be stored in xml format.
- CDR – recorded data will be stored in binary CDR format.
Previous to version 6.4 only XML format was supported.
When you first launch the RnR Manager it needs write access to the Eclipse subdirectory in order to set up the workspace. How can I configure the tool to set up a writeable area per user area?
RnR Manager is started by executing the startRnRManager script, located in the eclipse directory of the RnR Manager install directory. The script’s purpose is to ensure the proper setting of the OpenSplice environment variables prior to application launch.
The script allows for command line options to be passed to the application. Any command line options accepted by an Eclipse application are also accepted by RnR Manager. A particularly useful option is -data , which allows a user to specify a custom directory to use as the RnR Manager workspace in case the default directory is shared or write protected. Example of starting RnR Manager with a non default workspace location: /startRnRManager.sh -data /home/user/rnrworkspace \startRnRManager.bat -data C:\Users\user\rnrworkspace.
Is it possible to record two topics simultaneously using two different storages?
Yes, this is indeed possible. There are no constraints on the number of recordings or the mapping between Topics and Storages.
