I decided to download the OEM12c software from Oracle to install the new OEM.
After downloading the software, I had some trouble unzipping the two files.
The files downloaded where :
When unzipping the files, the following error occurred :
[oracle@localhost software]$ unzip em12_linux_x86_disk2of2.zip
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of em12_linux_x86_disk2of2.zip or
em12_linux_x86_disk2of2.zip.zip, and cannot find em12_linux_x86_disk2of2.zip.ZIP, period.
The same error occured at both zip files, so I decided to download them again.... :(
After the second download, the unzip still showed the same errors. I downloaded the unzip from the download site...still no change. Then I downloaded the unzip for large files, the LINUX Intel (32bit and 64bit - Large file support) unzip tool. This time no errors...
