Common Management of Oracle 11g RAC

Common Management of Oracle 11g RAC is in Oracle 11g RAC. The main management tools are srvctl and crsctl. Srvctl (Server Control) is a command line tool used to manage resources defined on the Oracle Cluster Registry (OCR. Www.2cto.com these resources include node applications, which constitute Oracle Cluterware and include the Oracle Notification Service (ONS), the Global Services Daemon (GSD ), and the Virtual IP (VIP ).
Other resources can also be managed by SRVCTL, such as databases, instances, listeners, services, and applications. SRVCTL allows you to start or stop nodeapps, databases, instances, listeners, and services, delete or remove instances and services, add services, and manage configuration information. Crsctl (Cluster Ready Services Control) is a command line tool that can be used to manage Oracle Clusterware daemons (daemon, also known as daemon and background processes, whose names end with a letter d ). These daemon include Cluster Synchronization Services (CSS), Cluster-Ready Services (CRS), and Event Manager (EVM ).
With CRSCTL, you can start or stop an Oracle Cluster to determine the current status of Oracle Clusterware. Through these two tools, we can manage Oracle 11g RAC. 1. To view the status of each resource (nodeapps node application, ASM instance, database instance, etc.), execute these commands under the grid user. Crs_stat-t this is a tool compatible with 10 Gb.

It is retained for backward compatibility and does not affect performance, do not try to enable them. Just ignore them. 2. To check the cluster running status, run these commands under the grid user. Trc code/home/grid @ serv1 => + ASM1 $ crsctl check-h Usage: crsctl check crs Check status of OHAS and CRS stack crsctl check cluster [[-all] | [-n <server> [...] check status of CRS stack crsctl check ctss Check status of Cluster Time Synchronization Services crsctl check resource {<resName> [...] |-w <filter >}[-n <server>] [-k <cid>] [-d <did>] Check status of resource (s) crsctl check css Check status Cluster Synchronization Services 3. Check the nodeapps status www.2cto.com and execute these commands under the grid user.

Trc code/home/grid @ serv1 => + ASM1 $ srvctl status database-d elvdb Instance elvdb1 is running on node serv1 Instance elvdb2 is running on node serv2 5. Check the asm status in run these commands under the grid user. /Home/grid @ serv1 => + ASM1 $ srvctl status asmASM is running on serv1, serv2 6. Run these commands under the root user to start and close the cluster. [Root @ serv1 bin] #. /crsctl stop cluster-n serv1 [root @ serv1 bin] #. /crsctl stop cluster-all [root @ serv1 bin] #. /crsctl stop cluster-n serv1-f force disable [root @ serv1 bin] #. /crsctl start cluster-n serv1 www.2cto.com disable CRS system restart and automatic start [root @ serv1 bin] #. /crsctl disable crsCRS-4621: Oracle High Availability Services autostart is disabled. check whether the crs is configured to automatically start [root @ serv1 bin] #. /crsctl config crsCRS-4621: Orac Le High Availability Services autostart is disabled. enable the CRS system to restart and automatically start [root @ serv1 bin] #. /crsctl enable crsCRS-4622: Oracle High Availability Services autostart is enabled.

The ocr and votedisk checks require you to run these commands under the grid user, crsctl query css votedisk and ocrcheck.
