Re: HAnging ORACLE database

Vikas,

[Quoted] It sounds like you are having problems archiving redo logs. I have experienced similar symptoms in the distant past when there is no more room in the archive destination. Any number of things could cause this:

1. The log_archive_dest is not a valid directory
2. The log_archive_dest is not owner by "oracle" or does not have correct permissions
3. Someone other than "oracle" starts the database
4. There is no more room on the device that contains the log_archive_dest
5. The log_archive_format parameter is not set properly
