1 Oracle Internet Directory requires Oracle8i database release 8.1.6. If this database is not installed and you select this installation type, a database is automatically installed for you.

Note: Oracle8i database release 8.1.6 is only compatible with Oracle Internet Directory release 2.0.6 (both on the product CD-ROM). Oracle Internet Directory releases prior to 2.0.6 are not compatible. In addition, you cannot upgrade a pre-2.0.6 release of Oracle Internet Directory to work with Oracle8i database release 8.1.6.

Migrating and Upgrading Requirements

The following sections describe specific migration requirements:

• Oracle7 and Oracle8 Migration and Upgrade Requirements

• Oracle Parallel Server Migration and Upgrade Requirements

Oracle7 and Oracle8 Migration and Upgrade Requirements

Oracle7 and Oracle8 database migration and upgrade procedures on Windows NT are covered in Oracle8i Migration. This section describes several Windows NT-specific issues to understand before following the instructions in Oracle8i Migration.

Migrating from Releases Prior to 7.1.3.3.6

If the database release is prior to release 7.1.3.3.6, migrate it to at least release 7.1.3.3.6 before using the Migration Utility or Oracle Data Migration Assistant to migrate it to release 8.1.6. See the documentation that accompanied your previous database release for information on how to migrate it to release 7.1.3.3.6.

Using Oracle Command Line Tools with the Migration Utility

If you use the Migration Utility to migrate or upgrade your Oracle database, the instructions in Oracle8i Migration prompt you to enter information at the command prompt of an Oracle tool. The command tool to use (SQL*DBA, Server Manager, or SQL*Plus) depends upon the database release from which you are migrating or upgrading. This table describes the tools to use and the method for starting these tools:

If...	From Oracle Release...	Use...	By Entering...
Migrating	7.1.x	SQL*DBA	C:\> SQLDBA71 MODE=LINE
	7.2.x	SQL*DBA	C:\> SQLDBA72 MODE=LINE
	7.3.x	Server Manager	C:\> SVRMGR23
Upgrading	8.0.x	Server Manager	C:\> SVRMGR30
	8.1.x	Server Manager or SQL*Plus	C:\> SVRMGRL or C:\> SQLPLUS

If you use the Migration Utility to migrate or upgrade your Oracle database, the instructions in Oracle8i Migration also prompt you to use the ORADIM command line tool. ORADIM is a utility for creating, starting, stopping, and modifying database instances on Windows NT. The method for starting ORADIM depends upon the database release from which you are migrating or upgrading:

If...	From Oracle Release...	Use...	By Entering...
Migrating	7.1.x	ORADIM71	C:\> ORADIM71 OPTIONS
	7.2.x	ORADIM72	C:\> ORADIM72 OPTIONS
	7.3.x	ORADIM73	C:\> ORADIM73 OPTIONS
Upgrading	8.0.x	ORADIM80	C:\> ORADIM80 OPTIONS
	8.1.x	ORADIM	C:\> ORADIM OPTIONS

See the Oracle8i Administrator's Guide for Windows NT for more information on using ORADIM.

Required Oracle7 Server SQL*Net Patch Releases

When migrating from Oracle7 Server release 7.3.2 or 7.3.3 to release 8.1.6, install the appropriate patch of SQL*Net in the 7.3.2 or 7.3.3 Oracle home before migrating with either Oracle Data Migration Assistant or the Migration Utility. Migration fails if you do not install the appropriate versions of SQL*Net. This table describes the required SQL*Net patch releases. Obtain these patches and installation instructions from Oracle Support Services.

:

If Migrating From...	Use This Release...
Release 7.3.3	2.3.3.0.3
Release 7.3.2	2.3.2.1.4
	2.3.2.1.12

Oracle Parallel Server Migration and Upgrade Requirements

All Oracle Parallel Server migration and upgrade issues on Windows NT are covered in the Oracle Parallel Server Administrator's Guide for Windows NT.

Mandatory Individual Component Requirements

This table identifies mandatory individual component requirements that must be met before installation. See Appendix A, "Individual Components Available for Installation" for the installation types with which these components can be installed. Appropriate documentation for preinstallation procedures is also identified. This table does not include Oracle Enterprise Manager component preinstallation requirements. That information is described in "Oracle Enterprise Manager Requirements".

Oracle Parallel Server	Perform the following tasks: Install the vendor-supplied operating system dependent layer. This layer must be Oracle certified. Set up raw devices before installing Oracle8i Enterprise Edition and Oracle Parallel Server. Install Oracle Parallel Server only on a disk that is private to and exclusively owned by the installation system (for example, the system disk). Unless you have specific reasons to do so and understand the risks involved, do not install Oracle Parallel Server on a disk that can be owned or mounted by more than one system.

Oracle Enterprise Manager Requirements

The three main Oracle Enterprise Manager tiers (Oracle Management Server, Oracle Enterprise Manager Client, and Oracle Intelligent Agent) are installable through several of the installation types described in Appendix A, "Individual Components Available for Installation".

The system requirements for these installation types were described earlier in "Top-Level Component System Requirements". In addition to those system requirements, review the following requirements before beginning installation of Oracle Enterprise Manager:

• Compatibility of Different Oracle Enterprise Manager Releases

• Oracle Enterprise Manager Web Browser Requirements

• Repository Migration and Backup Requirements

• Paging Service Agent Extensions Requirements

Compatibility of Different Oracle Enterprise Manager Releases

The Oracle Enterprise Manager Console, DBA Management Pack, separately licensable packs, Oracle Management Server, and repository must all be of the same release. For example, you cannot use a:

• Release 2.0 Oracle Management Server and repository with a release 2.1 Oracle Enterprise Manager Console

• Release 2.1 Oracle Management Server repository with a release 2.0 pack

The following release 2.1 components must use a release 2.1 Oracle Management Server and repository:

• Oracle Enterprise Manager Console

• Oracle DBA Management Pack

• Oracle Tuning Pack

• Oracle Diagnostics Pack

• Oracle Change Management Pack

• Oracle Management Pack for Oracle Applications

• Oracle Management Pack for SAP R/3

• Oracle Standard Management Pack

If the existing Oracle Management Server and repository are of a previous release, then migrate or upgrade them to the most recent release. In the case of migrating or upgrading an Oracle Management Server and repository to release 2.1, ensure that all Oracle Enterprise Manager components to use with the repository are also release 2.1. For example, do not upgrade the Oracle Management Server and repository to release 2.1 if you are still using Diagnostics Pack release 2.0 or Change Management Pack release 2.0. If you upgrade your Oracle Management Server and repository to release 2.1 before obtaining the release 2.1 pack software, you cannot use the older pack components.
