Use MD5 to validate the exchanged files between Oracle and Customer

Oracle Supports may ask customers to upload some data files (Database Dump, Trace Log, etc) for research. We often see the scenario that the uploaded huge files are corrupted and have to ask to re-upload. Then we may waste much time during this period. To avoid this, customers can tell Support the MD5 checksum of the upload files, requesting support to validate same if they have gotten the correct file in good format.

MD5 on Linux

We can use "md5sum" command directly. For example we calculate the file PrintManager.class MD5 checksum value.

[jijichen@jclinux temp]$ md5sum PrintManager.class
e0bf8c7623240ccd15ee17c0478427a1  PrintManager.class


MD5 on Windows

There are many freeware to calculate MD5 on internet. For example we can use WinMD5Free tool.

You can download it from here.
