Installing the Oracle relational database

Edit online

The second step in the installation of Oracle RAC is to install the Oracle relational database (RDBMS).

Installing RDBMS and the ASM file system can be done together using the Oracle installer, or the database can be installed on all the nodes, then ASM can be installed on all the nodes, starting with installation of 10.2.0.2 and then upgrading to 10.2.0.4. For this study, the RDBMS installation was done without the installation of ASM, because it was decided to install ASM as a separate step after putting RDBMS on both the nodes.

It is possible to install the base level with OUI, then the upgrade with OUI software, then run the root.sh script once on each node, and then do the manual steps only once. To perform the RDBMS installation, complete these steps:

  1. When installation package 10202_zlinux_database.zip is unpacked, open the directory named Disk2, which has a version of the runInstaller program.
  2. Start runInstaller.
  3. On the first panel, select Enterprise Edition for Linux on System z.
  4. Select Cluster installation to install identical software on all of the nodes that can be selected from a list.
  5. A panel named Product-Specific Checks issues messages on the readiness of the system to accept the installation. If there are any problems, you must resolve them before continuing.
  6. At this point in the RDBMS installation, it is possible to create a database and use the installer to define table spaces and data structures. However, for this study a database was created later using scripts, and the installer was not used for database creation.
  7. The details of the proposed installation of RDBMS are displayed, and they can be accepted or changed.
  8. Similar to the clusterware installation (see Installing Oracle clusterware 10.2.0.2), during the installation of the binaries there is an error message. The problem can be resolved by following the instructions for a manual change to the lib and lib32 libraries.

    Copy the same new versions of lib/libclient10.a and lib32/libclient32.a to the binary directory, and then click Retry as described in Installing Oracle clusterware 10.2.0.2.

  9. The installation runs and then displays a window instructing you to run the root.sh script on each of the nodes, in the same order that was used during the clusterware installation.
  10. The sequence ends with a return to the OUI after running the root scripts.
  11. Sign off, which causes the messages and logs from the installation to be displayed.
  12. Review these logs and save a copy for future reference and problem determination.

When you have completed these tasks, the final step of the Oracle RAC installation is to install the Oracle Automatic Storage Manager (ASM). See Installing the Oracle Automatic Storage Manager.
