Unix - CRON실행(Solaris 9 or earlier versions, Solaris 10)
Posted 05 7, 2010 11:34, Filed under: System/UNIXService management details
svcs(1) command
System administrators can more easily monitor services using Solaris Service Manager’s service status information and service activation/deactivation interfaces based on the commands (svcs(1), svcadm(1) etc). Until Solaris 9, it was a complicated procedure to understand service status. Service level information was not provided and system administrators have to assume service status from their own analysis of kernel level information. A slow and error prone process.
svcadm(1M) command
Services and the services on which they depend are started in their appropriate order using the Solaris Service Manager svcadm(1) command. System administrators are longer required to run complicated service startup operations.
For example, if there are two services, Service A and Service B, and Service A depends on Service B, previously the system administrator needed to start the services paying close attention to their dependent relationship. Now with Solaris10, they only have to start Service A. Solaris Service Manager automatically detects that Service B needs to be started, and starts the services in the right sequence.
With Solaris 10 the traditional service stop procedure using the kill(1) or pkill(1) commands is no longer available. This is because, once stopped, Solaris Service Manager will automatically restart them. So a new command, svcadm (1M) is now used for stopping services.
| Solaris 9 or earlier versions | Solaris 10 | |
|---|---|---|
| Service status | ps(1) command (only process information is shown) |
svcs(1) or ps(1) command |
| Service stop | # /etc/init.d/cron stop | # svcadm disable -t system/cron:default |
| Service restart (temporary) | # /etc/init.d cron start | # svcadm enable -t system/cron:default |
| Service stop After service restart the service isn't started |
(1)# /etc/init.d/cron stop (2)# mv /etc/rc2.d/S75cron /etc/rc2.d/_S75cron (Need to rename the service start script) |
# svcadm disable -t system/cron:default |
| Service restart (permanent) | (1) # /etc/init.d/cron stop (2) # /etc/init.d/cron start |
# svcadm restart -t system/cron:default |
- Solaris 10 간단한 재실행
