Meanwhile, as we delve into the world of Oracle databases, it is essential to consider the various storage management options available. Furthermore, one of the most critical components of a database is its storage system, which can significantly impact performance, scalability, and reliability. In addition, Oracle Automatic Storage Management (ASM) is a popular choice among database administrators due to its ability to provide a unified storage system for Oracle databases. Consequently, in this article, we will explore the step-by-step installation process of Oracle Automatic Storage Management 18c.
Introduction to Oracle Automatic Storage Management
Notably, Oracle Automatic Storage Management (ASM) is a robust storage management system designed to simplify the management of Oracle databases. Moreover, ASM provides a unified storage system for Oracle databases, allowing database administrators to manage storage resources more efficiently. Meanwhile, ASM offers several benefits, including improved performance, scalability, and reliability. Nevertheless, to take advantage of these benefits, it is crucial to install and configure ASM correctly. In the meantime, it is recommended to consult the official Oracle Database documentation for more information on ASM.
System Requirements for Oracle Automatic Storage Management 18c
Subsequently, before installing Oracle Automatic Storage Management 18c, it is essential to ensure that the system meets the necessary requirements. Firstly, the system should have a minimum of 4 GB of RAM and 10 GB of free disk space. Secondly, the system should have a 64-bit operating system, such as Oracle Linux or Red Hat Enterprise Linux. Additionally, the system should have the necessary packages and dependencies installed, including the Oracle Preinstallation package. Consequently, the following packages and dependencies are required:
- oracle-database-preinstall-18c
- oracle-database-server-18c
- oracle-grid-infrastructure-18c
Step-by-Step Installation of Oracle Automatic Storage Management 18c
Meanwhile, the installation process of Oracle Automatic Storage Management 18c involves several steps. Firstly, it is necessary to download the Oracle Grid Infrastructure 18c software from the Oracle website. Secondly, it is essential to create a new Oracle home directory and extract the downloaded software to that directory. Next, it is necessary to run the Oracle Universal Installer (OUI) to install the Oracle Grid Infrastructure software. Consequently, the following script can be used to install the Oracle Grid Infrastructure software:
./runInstaller -ignorePrereq -wait_for_completion
"ORACLE_HOME=/u01/app/oracle/product/18.0.0/dbhome_1"
"ORACLE_BASE=/u01/app/oracle"
"oracle.install.option=INSTALL_DB_SWONLY"
"oracle.install.db.InstallDatabaseConfiguration=true"
"oracle.install.db.config.storagetype=ASM"
"oracle.install.db.config_ASM DiskGroupName=DATA"
Configuring Oracle Automatic Storage Management 18c
Subsequently, after installing the Oracle Grid Infrastructure software, it is essential to configure the Oracle Automatic Storage Management (ASM) instance. Firstly, it is necessary to create a new ASM instance and configure the ASM disk groups. Secondly, it is essential to configure the ASM instance to use the Oracle grid infrastructure. Meanwhile, the following script can be used to create a new ASM instance:
asmca -silent -configureASM
-a /u01/app/oracle/product/18.0.0/dbhome_1
-o /u01/app/oracle
-t DATA
However, before proceeding with the configuration, it is recommended to consult the official Oracle Database documentation for more information on configuring ASM. Meanwhile, to get personalized support and guidance on Oracle database management, consider reaching out to PersonIT for expert services.
Verification and Testing of Oracle Automatic Storage Management 18c
Meanwhile, after configuring the Oracle Automatic Storage Management (ASM) instance, it is essential to verify and test the configuration. Firstly, it is necessary to verify that the ASM instance is running and that the disk groups are properly configured. Secondly, it is essential to test the ASM instance to ensure that it is functioning correctly. Consequently, the following script can be used to verify the ASM instance:
asmcmd lsdg
Conclusion
Finally, in conclusion, the installation and configuration of Oracle Automatic Storage Management 18c require careful planning and attention to detail. Meanwhile, by following the steps outlined in this article, database administrators can ensure a successful installation and configuration of ASM. Nevertheless, for more complex installations or configurations, it is recommended to seek the expertise of a professional Oracle database administrator or consider reaching out to PersonIT for expert services.
