Back up and restore Oracle databases in Java

Back up and restore the Oracle database in Java. I don't know if there are any better methods. I hope some of them can also provide the following methods or code.

Package com. servlet. util;

Import java. io. File;
Import java. io. FileOutputStream;
Import java. io. IOException;
Import java. io. InputStream;
Import java. nio. ByteBuffer;
Import java. nio. channels. Channels;
Import java. nio. channels. FileChannel;
Import java. nio. channels. ReadableByteChannel;
Import java. util. ArrayList;
Import java. util. List;
Import java. util. Map;

Public class BackupOracleDatabase {

/** User name */
Private String userName;
/** Password */
Private String userPass;

Private String serverAddr;

Private String logPath;

/**

Public BackupOracleDatabase (String Name, String Pass,
String Addr, String FilePath, String log ){
This. userName = Name;
This. userPass = Pass;
This. serverAddr = Addr;
This. backupFilePath = FilePath;
This. logPath = log;
}

 
/**

* @ Return commStr command string
*/
Private String GetCommand (boolean bool ){
String commStr = "EXP @ USER @/@ PASSWORD @ SERVER @ FILE = @ FILEPATH @ LOG = @ LOGPATH @ FULL = Y ";
If (bool ){
CommStr = "IMP @ USER @/@ PASSWORD @ SERVER @ FILE = @ FILEPATH @ LOG = @ LOGPATH @ FULL = Y ";
}
String temp = commStr. replaceAll ("@ USER @", this. userName ). replaceAll ("@ PASSWORD @", this. userPass ). replaceAll ("@ SERVER @", this. serverAddr ). replaceAll ("@ FILEPATH @", this. backupFilePath ). replaceAll ("@ LOGPATH @", this. logPath );
System. out. println (temp );
Return temp;
}
