The changemode command allows you to change the performance mode for Ops Center Automator. There are two performance modes, standard and high performance.
- Standard mode
- This is the default mode which supports running a single Online Migration with Configuration Manager task.
- High performance mode
- Use high performance mode if you need to run multiple Online Migration with Configuration Manager tasks concurrently. If you select this mode, you will need to change the logger.TA.MaxFileSize and plugin.threadPoolSize parameters in config_user.properties. For more information, see "Changing the system configuration" in the Hitachi Ops Center Automator Installation and Configuration Guide.
