Case sensitivity
Commands are not case sensitive; however parameters and device names, like server and processes, are case sensitive.
Recall command history
Use the up and down arrow keys on your keyboard to scroll through the command history.
Command repeat option
Commands can be run continuously using the “-r” option. The repeat option repeats a command every 5 seconds. You can change the repeat interval to be between 1 and 60 seconds by adding the number of seconds after the command.
This is useful to check status in real-time mode. For example to repeat the GetProcessStatus command every 2 seconds:
mcsadmin> getProcessStatus -r2 repeating the command 'GetProcessStatus' every 2 seconds, enter CTRL-D to stop getprocessstatus Fri Jun 10 19:31:28 2016 MariaDB Columnstore Process statuses Process Module Status Last Status Change Process ID ------------------ ------ --------------- ------------------------ ---------- ProcessMonitor pm1 ACTIVE Fri Jun 10 01:50:04 2016 2487 ProcessManager pm1 ACTIVE Fri Jun 10 01:50:10 2016 2673 SNMPTrapDaemon pm1 ACTIVE Fri Jun 10 01:50:16 2016 3534 DBRMControllerNode pm1 ACTIVE Fri Jun 10 01:50:20 2016 3585 ServerMonitor pm1 ACTIVE Fri Jun 10 01:50:22 2016 3625 DBRMWorkerNode pm1 ACTIVE Fri Jun 10 01:50:22 2016 3665 DecomSvr pm1 ACTIVE Fri Jun 10 01:50:26 2016 3742 PrimProc pm1 ACTIVE Fri Jun 10 01:50:28 2016 3770 ExeMgr pm1 ACTIVE Fri Jun 10 01:50:32 2016 3844 WriteEngineServer pm1 ACTIVE Fri Jun 10 01:50:36 2016 3934 DDLProc pm1 ACTIVE Fri Jun 10 01:50:40 2016 3991 DMLProc pm1 ACTIVE Fri Jun 10 01:50:45 2016 4058 mysqld pm1 ACTIVE Fri Jun 10 01:50:22 2016 2975
