The SRVCTL commands – CRS Oracle, perform various operations such as starting and stopping instances, moving or removing instances and services.
In addition, SRVCTL commands handle configuration information and cluster resources.
The SRVCTL process SRVCTL can be used to start and stop the database and instances by sending requests to the Oracle Clusterware (CRSD) process, which then starts or stops the Oracle Clusterware resources.
Furthermore, the Server Control utility (SRVCTL) is installed on each node by default.
Finally, it is possible to use SRVCTL to add services.
The SRVCTL command has 3 distinct uses
General cluster database administration activities with SRVCTL Cluster database configuration activities with SRVCTL Node-level operations with SRVCTL General database administration activities include:
Start and stop cluster databases Start and stop cluster database instances Start, stop and relocate cluster database services Get statuses of cluster databases, cluster database instances, or cluster database services Database configuration activities include:
Add, modify, and delete cluster database configuration information. Add an instance or service and remove an instance or service from a cluster database configuration. Move instances and services within a cluster database configuration and modify service configurations. Set up and disable the environment for an instance or service in a cluster database configuration. Set up and disable the environment for an entire cluster database in a cluster database configuration. Node-level activities include:
Addition and deletion of node-level applications. Setting up and tearing down the environment for node-level applications. Administration of node-level applications. Administration of ASM instances. Start and stop a program group that includes virtual IP addresses, listeners, Oracle Notification Services, and Oracle Enterprise Manager agents (for maintenance purposes). Therefore, in the SRVCTL – CRS Oracle Commands category, we provide the most commonly used SRVCTL commands.
SRVCTL RELOCATE SERVICE With the article “srvctl relocate service,” we provide the command to relocate an Oracle service registered in the cluster from one node to another in the RAC using CRS. It may happen that for some reason, such as hardware failure, maintenance activity, or updates, one of the Read more…
With the article you are about to read: srvctl start service, we provide the command to start an Oracle service registered in the cluster through CRS. Before executing the start, let’s check the status of resources with the command: crsctl status res -t The command to execute srvctl start service Read more…
With the article “srvctl stop service,” we provide the command to stop an Oracle service registered in the cluster through CRS. Before executing the stop, check the status of resources with the command: crsctl status res -t The command to execute srvctl stop service is: srvctl stop service -d <database> Read more…
srvctl stop su Oracle With the article “srvctl stop listener,” we provide the command to stop the Oracle listener on a node of an RAC through CRS. As indicated in the article srvctl start listener, the LISTENER is the process that allows network connections to the database. Specifically, it handles the Read more…
With the article “srvctl stop instance,” we provide the command to stop an Oracle instance in an RAC through CRS, which is described in the following LINK. It often happens that in the context of tuning activities, for example, adjusting the SGA (System Global Area), which is the portion of RAM Read more…
srvctl start instance With the article “srvctl start instance,” we provide the command to start an Oracle instance in an RAC through CRS. This command is executed in cases where the instance needs to be started after a previous stop, for example, to modify RAM parameters such as SGA. Alternatively, Read more…
With the article “srvctl start database,” we provide the command to start all instances of an Oracle database in an RAC through CRS. When facing server maintenance activities involving an RAC, we are required to stop all instances that make up the Oracle cluster. No worries. We’ve got you covered. Read more…
With the article “srvctl stop database,” we provide the command to stop all instances of an Oracle database in an RAC via CRS. In previous articles, we extensively discussed the scenarios that could arise when stopping RAC instances. The main reasons include: server maintenance activities, which can range from server Read more…
