[Description]

When installing oracle software, beginners often lack some packages before installation, so some "errors" will be prompted during the installation process, and sometimes ignore these errors, the installation of oracle software will be completed, but such a database may leak problems at some point in the future. Therefore, if an error is reported, we recommend that you, after the installation is stopped or the installation is complete, uninstall it. If an error is found, it is a proper solution to reinstall the oracle software.

Today, for example, an error is reported during installation because a 32-bit installation package is missing, but the installation is ignored. The installation is completed (only the installation of the oracle software is completed and no database creation is completed, this also shows that the advantage of separating oracle software from dbca database creation lies in the fact that troubleshooting can be performed in a timely manner to avoid wasting too much time on useless operations ). The cause is found, so you can uninstall the oracle software before creating the database in dbca. The method is as follows:

[Example]

Environment: CentOS 6.2

Database: Oracle 10.2.0.1

Objective: To uninstall and reinstall the incomplete Oracle software because the required package is missing during Oracle software installation.

Start Operation:

[Oracle @ hyl/] $ cd $ ORACLE_HOME

[Oracle @ hyl db_1] $ ls
