Installer Planning Checklist for Oracle Database Client

Use this checklist to assist you to be prepared before starting Oracle Universal Installer.

Table 1-6 Oracle Universal Installer Planning Checklist for Oracle Database Client Installation

Check	Task
Read the Release Notes	Review release notes for your platform, which are available for your release at the following URL: http://docs.oracle.com/en/database/database.html
Review the Licensing Information	You are permitted to use only those components in the Oracle AI Database for which you have purchased licenses. For more information about licenses, refer to the following URL: Oracle AI Database Licensing Information User Manual
Review Oracle Support Certification Matrix	New platforms and operating system software versions might be certified after this guide is published, review the certification matrix on the My Oracle Support website for the most up-to-date list of certified hardware platforms and operating system versions: https://support.oracle.com/ You must register online before using My Oracle Support. After logging in, from the menu options, select the Certifications tab. On the Certifications page, use the Certification Search options to search by Product, Release, and Platform. You can also search using the Certification Quick Link options such as Product Delivery, and Lifetime Support.
Run OUI with CVU and use fixup scripts	Oracle Universal Installer is fully integrated with Cluster Verification Utility (CVU), automating many CVU prerequisite checks. Oracle Universal Installer runs all prerequisite checks and creates fixup scripts when you run the installer. You can run OUI up to the Summary screen without starting the installation. You can also run CVU commands manually to check system readiness. For more information, see: Oracle Clusterware Administration and Deployment Guide
Ensure cron jobs do not run during installation	If the installer is running when daily cron jobs start, then you may encounter unexplained installation problems if your cron job is performing cleanup, and temporary files are deleted before the installation is finished. Oracle recommends that you complete installation before daily cron jobs are run, or disable daily cron jobs that perform cleanup until after the installation is completed.
Decide the client installation type	You can choose one of the following installation types when installing Oracle Database Client using the Setup Wizard: Administrator: Enables applications to connect to an Oracle AI Database instance on the local system or on a remote system. It also provides tools that enable you to administer Oracle AI Database. Runtime: Enables applications to connect to an Oracle AI Database instance on the local system or on a remote system. Custom: Enables you to select individual components from the list of Administrator and Runtime components. Instant Client: Enables you to install only the shared libraries required by Oracle Call Interface (OCI), Oracle C++ Call Interface (OCCI), Pro*C, or Java database connectivity (JDBC) OCI applications. This installation type requires much less disk space than the other Oracle Database Client installation types. For more information about Oracle Database Instant Client see the following URL: https://www.oracle.com/database/technologies/instant-client.html Note: Starting with Oracle Database Client 26ai, the Setup Wizard no longer provides the option to install Oracle Instant Client.
Obtain your My Oracle Support account information.	During installation, you require a My Oracle Support user name and password to configure security updates, download software updates, and other installation tasks. You can register for My Oracle Support at the following URL: https://support.oracle.com/
Oracle Database Client and Oracle AI Database interoperability	For information about interoperability between Oracle Database Client and Oracle AI Database releases, see My Oracle Support Note 207303.1. 32-bit Oracle Database clients are desupported in Oracle AI Database 26ai. Oracle has discontinued developing 32-bit Oracle Database clients. Oracle recommends that you use 64-bit Oracle Database clients. If you are using 32-bit applications, then you can continue to use older 32-bit Oracle Database clients, subject to “Client / Server Interoperability Support Matrix for Different Oracle Versions (Doc ID 207303.1)," and the release support lifecycle (My Oracle Support 742060.1).
