Oracle installation and the problems it encounters

The Oracle installation process actually has a lot of documentation to refer to.

Take the oracle11g release version as an example:

Downloaded from the official website zip, contains two parts, Win32_11gr2_database_1of2.zip and Win32_11gr2_database_2of2.zip two packs are big and small, one major installation, the other is to copy the files in the package.

Copy the files from the \stage\components in the 2OF2 to the corresponding location in 1of2 for Setup.exe installation.

Because a lot of people say that Oracle has gone wrong, usually reinstall, but uninstall and cumbersome, often lead to the reinstallation of the system. So a lot of people in the installation process is very careful.

In fact, in the installation process is not necessary, often there are errors, you can click Abort, although it has been installed part, but that is only the file copy of the past, as long as not to go to the final step of the installation success, there is still a chance.

Sometimes do not find the corresponding file, like the first installation, and did not put the above mentioned in the components of the files in the file, there is no problem, then you can choose to abort the installation. When there is a way to continue Setup.exe installation, the same can be installed successfully. The above is the first problem and the file cannot be found.

The second problem, found in the abort after the installation, after installation, through the browser access to the EM failure, the browser reported that this site's security certificate expired issue.

When you enter CMD,

Input, EMCTL status Dbconsole

The return is: environment variable oracle_unqname not defined. Please set Oracle_unqname to database unique name.

This is the problem that arises.

Workaround 1, enter set Oracle_unqname= ORCL

This method fails if oc4j Configuration issue appears.

Workaround 2, enter set oracle_hostname = localhost

No response, is the best response.

Go back and enter Emctl status Dbconsole

Next, Certutil-setreg Chain\enableweaksignatureflags 8

Complete.
