Displaying Quick I/O Status and File Attributes
You can obtain and display information about Quick I/O status and file attributes using various options of the ls command.
Options
-al
|
Lists all files on a file system, including Quick I/O files and their links.
|
-lL
|
Shows if Quick I/O was successfully installed and enabled.
|
-alL
|
Shows how a Quick I/O file name is resolved to that of a raw device.
|
To list all files on the current file system, including Quick I/O files and their links
Use the ls -al command with the file names:
$ ls -al filename .filename
Example
To show the absolute path name created using qiomkfile with the -a option:
$ ls -al d* .d*
-rw-r--r-- 1 oracle dba 104890368 Oct 2 13:42 .dbfile
lrwxrwxrwx 1 oracle dba 19 Oct 2 13:42 dbfile -> \
.dbfile::cdev:vxfs:
To determine if a datafile has been converted to Quick I/O
Use the ls command as follows:
$ ls -lL filename
Example
To determine if Quick I/O is installed and enabled:
$ ls -lL dbfile
crw-r--r-- 1 oracle dba 45, 1 Oct 2 13:42 dbfile
crw-r--r-- 1 oracle dba 237 0x000004 Oct 2 13:42 dbfile
where the first character, c, indicates it is a raw character device file, and the major and minor device numbers are displayed in the size field. If you see the raw device indication (c) and the size field is zero, Quick I/O did not install properly or does not have a valid license key.
To show a Quick I/O file resolved to a raw device
Use the ls command with the file names as follows:
$ ls -alL filename .filename
Example
To show how the Quick I/O file name dbfile is resolved to that of a raw device:
$ ls -alL d* .d*
crw-r--r-- 1 oracle dba 237 0x000004 Oct 2 13:42 dbfile
-rw-r--r-- 1 oracle dba 104890368 Oct 2 13:42 .dbfile
