When you use the CREATE DATABASE statement, Oracle creates the control files listed in the CONTROL_FILES parameter. If you don t include this parameter in your initialization file when creating the database, Oracle will create a control file using a default operating system dependent filename or, if you have enabled Oracle Managed Files, it will create Oracle-managed control files. You must have a minimum of one control file and may have up to eight control files per database. Example: CONTROL_FILES=('/u01/app/oracle/orcl11/control/ctl01.ora', ' /u01/app/ oracle/orcl11/control/ctl02.ora',/ u01/app/oracle/orcl11/control/ctl03.ora' Default value: Depends on the operating system Parameter type: Static

The CONTROL_FILE_RECORD_KEEP_TIME parameter specifies how many days Oracle will retain records in the control file before overwriting them. Oracle recommends that you set this parameter to a high value, to ensure that all online disk backup information remains in the control file. For example, if you maintain a flash recovery area that holds two full weekly backups and daily incremental backups, you must set CONTROL_FILE_RECORD_KEEP_TIME to at least 21 days. Example: CONTROL_FILE_RECORD_KEEP_TIME=14 Default value: Seven days Parameter type: Modifiable dynamically, with the ALTER SYSTEM statement

Listing 12-15. The C# Implementation of the HttpResponseHeader Class public class HttpResponseHeader { // key is name, value is value Hashtable headers = new Hashtable(); HttpStatusCode statusCode; public int ContentLength { get { if (!headers.Contains("Content-Length")) return 0; string s = headers["Content-Length"] as string; return int.Parse(s); } } public int SequenceNumber { get { if (!headers.Contains("Sequence-Number")) throw new Exception("Sequence-Number not found"); string s = headers["Sequence-Number"] as string; return int.Parse(s); } } public HttpResponseHeader(NetworkStream theNetworkStream) { StreamReader reader = GetStreamReader(theNetworkStream); Parse(reader); } StreamReader GetStreamReader(NetworkStream theNetworkStream) { const byte Cr = 0x0d; // UTF8 CarriageReturn // read the incoming data and return it as a StreamReader MemoryStream memoryStream = new MemoryStream(); byte b = (byte) theNetworkStream.ReadByte(); // the header ends with "\r\n\r\n" while (true) { while (b != Cr) { memoryStream.WriteByte(b); b = (byte) theNetworkStream.ReadByte(); }

You can use the UTL_FILE_DIR parameter to specify the directory (or directories) Oracle will use to process I/O when you use the Oracle UTL_FILE package to read from or write to the operating system files. You can set UTL_FILE_DIR to any OS directory you want. If you just specify an asterisk (*) instead of any specific directory name, the UTL_FILE package will read and write to and from all the OS directories; Oracle recommends against this practice. Example: UTL_FILE_DIR=/u01/app/oracle/utl_dir Default value: None; you can t use the UTL_FILE package to do any I/O with this setting. Parameter type: Static

You ll need to use some directory on the server where you have read/write privileges as the setting for

UTL_FILE_DIR; otherwise the package can t process I/O to the operating system. If you use * as the value for the UTL_FILE_DIR parameter, however, users can write to and read from all directories for which you have read/

memoryStream.WriteByte(b); // Cr b = (byte) theNetworkStream.ReadByte(); memoryStream.WriteByte(b); // Lf b = (byte) theNetworkStream.ReadByte(); if (b == Cr) { memoryStream.WriteByte(b); // Cr b = (byte) theNetworkStream.ReadByte(); memoryStream.WriteByte(b); // Lf memoryStream.Position = 0; StreamReader reader = new StreamReader(memoryStream, Encoding.UTF8); return reader; } } } public void Parse(StreamReader theReader) { headers.Clear(); ParseStatusCode(theReader); ParseOtherLines(theReader); } // the response must start with a string like this: // HTTP/1.1 200 OK\r\n void ParseStatusCode(StreamReader theReader) { string line = theReader.ReadLine(); if (!line.StartsWith("HTTP")) throw new Exception("Invalid response header"); string[] words = line.Split(' '); if (words.Length < 3) throw new Exception("Invalid response header"); int i = int.Parse(words[1]); statusCode = (HttpStatusCode) i; } void ParseOtherLines(StreamReader theReader) { string line = theReader.ReadLine(); while (line != null) { if (line == "") return; ParseLine(line); line = theReader.ReadLine(); } }

write privileges. Obviously, you don t want this to happen!

You ll need to use three parameters to specify the format of the Oracle Managed Files (OMF) when you decide to use the feature: DB_CREATE_FILE_DEST, DB_CREATE_ONLINE_LOG_DEST_n, and DB_RECOVERY_ FILE_DEST. I describe the first two parameters in the sections that follow and the third under the Recovery-Related Parameters section. 6 discusses in more detail how to use the initialization parameters dealing with OMF.
