Hello,
Thanks for any reply
This one is on Oracle File Manager.
This is relevant to version 6.0.
Suppose that I have a partition /dev/sd3g. I have a directory /oracle on which
is /dev/sd3g mounted. If I use the Create database statement to create one
data file "mydb" and two redo log files "redo1" and "redo2", from the
Unix shell prompt when I do "ls", I can see the three files
"mydb", "redo1" and "redo2" under oracle directory.
Does this mean that Oracle Filemanager is interacting with the UNIX file
manager and actual inodes are being created for these files ?
If inodes are being created, then does oracle access these files using
inode pointers or is it merely for listing the files for user's convenience ?
I don't see any reason why oracle should traverse the files using filesystem
inode pointers. Most files may be contiguously allocated and Oracle should
internally keep a directory of all files for a table to read the table.
Am I right or wrong. Please correct me.
I am sorry if I have confused you.
