Coexistence

This chapter describes the extra steps required to enable coexistence of Oracle products on one computer. The topics include:

7.1 Migration

If you are migrating from a previous version of Oracle9i Application Server (Oracle9iAS), perform the tasks described in the Migrating from Oracle9iAS Release 1 (1.0.2.2.x) to Release 2 (9.0.2).

The Oracle9iAS Migration Assistant enables you to migrate existing J2EE and Web Cache components from an Oracle9iAS Release 1, Version 1.0.2.2 installation to a Release 2, Version 9.0.2 installation. The Oracle9iAS Migration Assistant upgrades existing 1.0.2.2 versions of Oracle HTTP Server, Oracle9iAS Web Cache, and Oracle9iAS Containers for J2EE for compatibility with 9.0.2.

Instructions for using and installing the Oracle9iAS Migration Assistant are available in the Migrating from Oracle9iAS Release 1 (1.0.2.2.x) to Release 2 (9.0.2).

7.2 Oracle9iAS Metadata Repository Coexistence with Other Oracle Databases

Your Oracle9iAS Metadata Repository, installed as part of the Oracle9iAS Infrastructure installation, can coexist with existing installations of either the Oracle 8.1.7 Database or Oracle9i Database.

The following steps describe how to enable coexistence of Oracle9iAS Metadata Repository with the existing Oracle databases:

  1. Verify that the you are a member of the administrative group for existing installations of either the Oracle 8.1.7 Database or Oracle9i Database.

  2. Verify that your computer contains the following minimum hardware requirements for Oracle9iAS Metadata Repository installation and coexistence:

    • Disk space = 6 GB

    • TEMP or swap space = 1 GB

    • Memory = 1 GB

  3. Ensure the Oracle home directory selection for your Oracle9iAS Metadata Repository installation is in a different Oracle home than the Oracle 8.1.7 Database and the Oracle9i Database installations.

  4. Make sure the Inventory directory for the existing Oracle databases have read, write, and execute permissions for both the group and user.

  5. Make sure that the coexisting Oracle databases are running during Oracle9iAS Metadata Repository installation so that port conflicts can be resolved. Refer to Section 2.5.4.1, "Oracle9iAS Infrastructure Port Usage" to use a different port.

  6. Following installation of Oracle9iAS Metadata Repository, two directories, each named iasdb, are created in the admin and oradata directories of your existing Oracle database. The iasdb directories contain information regarding your Oracle9iAS Metadata Repository installation.

    If you want to deinstall your existing Oracle database and use the Oracle9iAS Metadata Repository, then you must not deinstall the admin and oradata directories.
