Ohasd is a daemon installed with Oracle grid infrastructure that starts software services, such as Oracle Automatic Storage Management. Because you have already installed Oracle grid infrastructure, Oracle Universal Installer will automatically add the database instance to the Oracle grid infrastructure configuration if you choose to create a database as part of the installation.

Follow the high-level instructions in this section to install Oracle grid infrastructure and configure it for an existing Oracle database. To install Oracle grid infrastructure for an existing database:. On the same host computer as the database, use Oracle Universal Installer to install the grid infrastructure, and select Install and Configure Grid Infrastructure for a Standalone Server as the installation option. Go to the Grid home bin directory.

Use the srvctl add database command to manually add the database, the listener, the Automatic Storage Management instance, all Automatic Storage Management disk groups, and any database services to the Oracle grid infrastructure configuration.

If you want to create additional disk groups or manually configure Automatic Storage Management disks, then you can run the Oracle Automatic Storage Management Configuration Assistant as follows:.

To test the Automatic Storage Management installation, try logging in by using the asmcmd command-line utility, which lets you manage Automatic Storage Management disk group files and directories. To do this:. Oracle Database Utilities for more information about asmcmd. Skip Headers. Oracle Restart improves the availability of your Oracle database by providing the following: When there is a hardware or a software failure, Oracle Restart automatically starts all Oracle components, including Oracle database instance, Oracle Net Listener, database services, and Automatic Storage Management.

Oracle Restart starts up components in the proper order when the database host is restarted. Note: If you want to use Automatic Storage Management or Oracle Restart, then you must first install Oracle grid infrastructure for a standalone server and then install Oracle Database. Oracle Restart is used in single-instance non-clustered environments only. The following table describes the relationship between installed RAM and the configured swap space requirement: Note: On Linux, the HugePages feature allocates non-swappable memory for large page tables using memory-mapped files.

In the past, adding or removing servers in a cluster required extensive manual preparation. With this release, you can continue to configure server nodes manually, or use Grid Plug and Play to configure them dynamically as nodes are added or removed from the cluster.

Grid Plug and Play reduces the costs of installing, configuring, and managing server nodes by starting a grid naming service within the cluster to allow each node to perform the following tasks dynamically:. Configuring or reconfiguring itself using profile data, making host names and addresses resolvable on the network. Because servers perform these tasks dynamically, the number of steps required to add or delete nodes is minimized.

IPMI operates independently of the operating system, and can operate even if the system is not powered on. With this release, you can install a new version of Oracle Clusterware into a separate home from an existing Oracle Clusterware installation. This feature reduces the downtime required to upgrade a node in the cluster. When performing an out-of-place upgrade, the old and new version of the software are present on the nodes at the same time, each in a different home location, but only one version of the software is active.

When Oracle Enterprise Manager is installed with Oracle Clusterware, it can provide a set of users that have the Oracle Clusterware Administrator role in Oracle Enterprise Manager, and provide full administrative and monitoring support for High Availability application and Oracle Clusterware resource management.

After you have completed the installation and deployed Oracle Enterprise Manager, you can provision nodes added to the cluster using Oracle Enterprise Manager. SCAN eliminates the need to change clients when nodes are added to or removed from the cluster.

Oracle Grid Infrastructure patching is automated across all nodes, and patches can be applied in a multi-node, multi-patch fashion. To streamline cluster installations, especially for those customers who are new to clustering, Oracle introduces the Typical Installation path. Typical installation defaults as many options as possible to those recommended as best practices.

OUI no longer removes Oracle software. Use the new Deinstallation tool deinstall. The Deinstallation tool can also be downloaded from Oracle Technology Network.

If so, select External for the redundancy. If the disks are not mirrored at the storage level, then choose Normal for the redundancy.

The passwords should be at least eight characters in length and include at least one alphabetic and one numeric character. Optionally, you can use the same password for all accounts. However, Oracle recommends that you specify a different password for each account. You must remember the passwords that you specify. If you choose to create only the dba group, then you can use that group for all three privileged groups.

In the Specify Installation Location screen, enter the following details, and click Next:. Oracle Base : Enter the directory location for Oracle base.

Because you have already installed Oracle Grid Infrastructure, Oracle Universal Installer will automatically add the database instance to the Oracle Grid Infrastructure configuration if you choose to create a database as part of the installation.

If a new database is installed after a grid infrastructure installation, then the listener runs from the Oracle Grid Infrastructure home. If you perform a database installation, then the database must use the same listener created during the Oracle Grid Infrastructure installation. If you are using Oracle Restart, then the default listener and any additional listeners must run from the Oracle Grid Infrastructure home.

Follow the high-level instructions in this section to install Oracle Grid Infrastructure and configure it for an existing Oracle database.

Please note that Oracle Restart can only manage existing However, Oracle database releases prior to Go to the Grid home's bin directory. Use the srvctl add database command to manually add the database, the listener, the Oracle ASM instance, all Oracle ASM disk groups, and any database services to the Oracle Grid Infrastructure configuration.

After installation, you must first stop the Oracle Restart stack to modify the software installed in your Grid home. After the Oracle Restart stack is completely shut down, perform the updates to the software installed in the Grid home. To test the Oracle ASM installation, try logging in by using the asmcmd command-line utility, which lets you manage Oracle ASM disk group files and directories. To do this:. Skip Headers.
