Note that after the first test, I ve used a special character, the underscore, which is a special filehandle This is a buffer that holds the information from the last file name or filehandle test, or the last stat command Using this special filehandle is more efficient than continually specifying the file, since this special filehandle stores all of the status information for the last file accessed If you specify each file or filehandle individually, the physical device holding the file will be polled each time for the information Be careful of foreign language files with high-bit or special characters, such as characters with accents They can sometimes be misinterpreted as a binary file when using -B or -T Beyond this standard set of tests, there is also a separate stat command that obtains further information about the file specified, including the physical device, underlying file system parameters such as the inode number, the owner and group permissions, and the access and modification times for the file The information is returned by the function as a list:

5 Connect as SYS with operating system authentication:

($dev, $inode, $mode, $nlink, $uid, $gid, $rdev $rdev, $size, $atime, $mtime, $ctime, $blksize, $blocks) = stat $file;

6 Start the instance only Then query the V$INSTANCE view and examine its STATUS column Note that the status of the instance is STARTED

The full list of information supplied is shown in Table 7-7 The stat function uses the operating system stat() function to obtain information directly from the inode (see sidebar), returning the list The information is very raw; for example, it returns user IDs rather than names, but using other functions seen elsewhere in this chapter, it s possible to extract the information to make it more usable The most complex procedure is the extraction of the permissions information, which is supplied back to use as a number, but needs to be treated as an octal value that many Unix programmers will be familiar with The following example shows one

It s therefore useful to factor the cluster size into determining the actual amount of space used by the files in a directory. The first thing to do is to figure out how to get the cluster size for a disk. You can access the cluster size for a disk by using the GetDiskFreeSpace() function. This is a Win32 function, so you ll need to use platform invoke to call it. It s nicest if you encapsulate this function in a class, which is as follows: public class ClusterSize { private ClusterSize() {} public static int GetClusterSize(string root) { int sectorsPerCluster = 0; int bytesPerSector = 0; int numberOfFreeClusters = 0; int totalNumberOfClusters = 0; Console.WriteLine("GetFreeSpace: {0}", root); bool result = GetDiskFreeSpace( root, ref sectorsPerCluster, ref bytesPerSector, ref numberOfFreeClusters, ref totalNumberOfClusters); return(sectorsPerCluster * bytesPerSector); } [DllImport("kernel32.dll", SetLastError=true)] static extern bool GetDiskFreeSpace( string rootPathName, ref int sectorsPerCluster, ref int bytesPerSector, ref int numberOfFreeClusters, ref int totalNumberOfClusters); } The declaration for the function is at the end of the class, and it follows the usual PInvoke format. The function gets the cluster size of a disk and returns the value. This function works, but it has a few problems. The first one is that it d be nicer to pass in a full directory rather than a disk name. The second one is that it d be convenient for every directory to call and get this function, but you don t want to call the function every time. In other words, you need to cache the value. You do this by keeping a static hash table that stores the cluster sizes for disks and then checking it calling the function. Add the following lines to the GetClusterSize() function:

An inode is the name for a directory entry within a file system The term inode comes from Unix, although all operating systems have a similar term for the inode Both Macs and NT use the term directory entry Regardless of the operating system or file system type, the primary purpose for an inode or directory entry is to store the information about the physical location of the data that constitutes a file on the physical (or logical) device Because this is effectively a mapping structure between the data and the name the user gives the file, an inode is also used to store other information such as the ownership and security information and other data obtainable with the stat function Inodes also play a part in the management of files

startup nomount; select status from v$instance;

0 1 2 3 4 5 6 7 8 9 10 11 12 Table 7-7

7 Mount the database and query the instance status The database has now been MOUNTED by the instance
