Now, start your Cell Services using the Linux
service
command:
3.
[root@cm01cel01 ~]# service celld start
Starting the RS, CELLSRV, and MS services...
Getting the state of RS services...
running
Starting CELLSRV services...
The STARTUP of CELLSRV services was successful.
Starting MS services...
The STARTUP of MS services was successful.
[root@cm01cel01 ~]#
Once you are comfortable with the service
celld start
and
stop
commands, you can
also manage Cell Services software using CellCLI's
alter cell
command. Assuming
your services are running, log in to your compute node as
root
or
celladmin
and run the
cellcli
command:
4.
[root@cm01cel01 ~]# cellcli -e alter cell shutdown services all
Stopping the RS, CELLSRV, and MS services...
The SHUTDOWN of services was successful.
[root@cm01cel01 ~]#
5.
Start your Cell Services software by running the cellcli command:
[root@cm01cel01 ~]# cellcli -e alter cell startup services all
Starting the RS, CELLSRV, and MS services...
CELL-01510: Cannot start a new Restart Server (RS) at port number: 9903. An instance of
RS might be already running.
Getting the state of RS services...
running
Starting CELLSRV services...
The STARTUP of CELLSRV services was successful.
Starting MS services...
The STARTUP of MS services was successful.
[root@cm01cel01 ~]#
■
note if you stop your Cell Services with
cellcli -e alter cell shutdown services all
, Exadata's restart
Server (rS) process will automatically start. running
cellcli -e alter cell startup services all
will generate a
CEll-01510 error indicating that the rS process is already running. in contrast, when you run
service celld stop
, the
restart Server will not restart and all services will be down.
Note
How It Works
The
/etc/init.d/celld
process is called at system boot to start your Exadata Cell Services software, but an Exadata
DMA can also manage Cell Services software by running either
service celld
or CellCLI's
alter cell
commands.
