Re: FILE IDENTIFY wait event

Daniel,

It is not Oracle decision to wait. Basically the file identity means that Oracle will open the file and read the first block to find the name of the file and the size of the file. So two system calls are done. The driver for the file that you will make the decision to return an error.
