Backup and Recovery under Windows NT

Before reading through this section, I strongly recommend that you go through the Windows NT programming section in Chapter 2. This section presents and explains the scripts for taking a backup and recovering a database in the Windows NT environment. Here, we use the DOS Shell batch programming techniques to automate the backup process.

After the backup is complete, it is important to check the backup status by reviewing log and error files generated by the scripts.

Cold Backup

Listing 3.9 performs a cold backup of a database under the Windows NT environment. The cold backup script takes SID, the instance to be backed up, as the input parameter. The general steps to write a backup script in Unix and Windows NT are the same. The only difference is that we will be using commands that are understood by Windows NT. Figure 3.6 shows the functionality of a cold backup program under Windows NT. Each box represents a corresponding section in the program. For example, the Parameter Checking section checks for the necessary input parameters and also checks for the existence of the backup directories.

Figure 3.6 Functions in cold backup script for Windows NT.

Cold Backup Script for Windows NT Checklist

  • Check to see that ORA_HOME, BACKUP_DIR, and TOOLS are set to correct values according to your directory structure. These variables are highlighted in the script.

  • Verify that CONNECT_USER is set to correct the username and password.

  • Define the INIT_FILE variable to the location of the Init.ora file.

  • Be sure that the user running the program has Write access to backup directories.

  • When you run the program, pass SID as a parameter.

Cold Backup under Windows NT Troubleshooting and Status Check

Backup log files defined by LOG_FILE contain detailed information about each step of the backup process. This is a very good place to start investigating why a backup has failed or for related errors. This file will also have the start and end time of backup. ERR_FILE has error information.

A single line about the success or failure of backup is appended to the SID.log file every time a backup is performed. This file is located under the directory defined by the LOGDIR variable. The messages for a cold backup are 'COLDBACKUP_FAIL', if the cold backup failed, and 'Cold Backup Completed successfully', if the backup completes successfully.

You can schedule automatic backups using the 'at' command, as shown in the following:

at  23:00 "c:\backup\coldbackup_nt.bat ORCL"
Runs at 23:00 hrs on current date.

at 23:00 /every:M,T,W,Th,F "c:\backup\coldbackup_nt.bat ORCL "

This command runs a backup at 23:00 hours every Monday, Tuesday, Wednesday, Thursday, and Friday.

The "Create Dynamic Files" section in the coldbackup_nt.bat program creates the coldbackup.sql file (see Listing 3.10) under the log directory. coldbackup.sql is called from coldbackup_nt.bat and generates a list of data, control, and redo log files to be backed up from the database. A sample coldbackup.sql is shown in Listing 3.10 for your understanding. The contents of this file are derived based on the structure of the database.

Listing 3.10 coldbackup.sql

set termout off  heading off  feedback off
set linesize 300 pagesize 0
set serveroutput on size 1000000

spool c:\backup\orcl\cold\log\coldbackup_list.bat

 exec dbms_output.put_line('@echo off' );

   exec dbms_output.put_line('REM ******Data files' );
   select 'copy '|| file_name|| '  c:\backup\orcl\cold\data   '
   from dba_data_files order by tablespace_name;

   exec dbms_output.put_line('REM ******Control files' );
   select 'copy '|| name|| '  c:\backup\orcl\cold\control   '
   from v$controlfile order by name;

  exec dbms_output.put_line('REM ******Init.ora file ' );
  select ' copy  c:\oracle\admin\orcl\pfile\init.ora
c:\backup\orcl\cold\control '
  from dual;
exec dbms_output.put_line('exit;');
spool offexit

When the coldbackup.sql file is called from the coldbackup_nt.bat program, it spools output to the coldbackup_list.bat DOS batch file (see Listing 3.11). This file has the commands necessary for performing the cold backup.

This is only a sample file. Note that in the contents of file data, control, redo log, and Init.ora files are copied to respective backup directories.

Listing 3.11 coldbackup_list.bat

@echo off

Hot backup program functionality can be shown with the similar diagram as for a cold backup. The sections and their purposes in the program are the same as for a cold backup.

Hot Backup Script under Windows NT Checklist

  • Check to see that ORA_HOME, BACKUP_DIR, and TOOLS are set to the correct values according to your directory structure. These variables are highlighted in the script.

  • Verify that CONNECT_USER is set to the correct username and password.

  • Define the INIT_FILE variable to the location of the Init.ora file.

  • Define the ARC_DEST variable to the location archive destination.

  • Be sure that the user running the program has Write access to the backup directories.

  • When you run the program, pass SID as a parameter.

Hot Backup under Windows NT Troubleshooting and Status Check

The backup log file defined by LOG_FILE contains detailed information about each step of the backup process. This is a very good place to start investigating why a backup has failed or for related errors. This file will also have the start and end time of backup. ERR_FILE has error information.

A single line about the success or failure of backup is appended to the SID.log file every time a backup is performed. This file is located under the directory defined by the LOGDIR variable. The messages for a hot backup are 'HOTBACKUP_FAIL', if a hot backup failed, and 'Hot Backup Completed successfully', if a backup completes successfully.

The "Create Dynamic Files" section, in the hotbackup_nt.bat creates the hotbackup.sql file (see Listing 3.13) under the log directory. This generates a list of tablespaces, data, control, and redo log files from the database. It is called from the hotbackup_nt.bat program.

Listing 3.13 hotbackup.sql

The hotbackup.sql file is called from hotbackup_nt.bat and it spools output to the hotbackup_list.sql SQL file (see Listing 3.14). This file has the commands necessary for performing a hot backup.

This is only a sample file. Note in the file that the data, control, archive log, and Init.ora files are copied to their respective backup directories. First, it puts the tablespace into Backup mode, copies the corresponding files to backup location, and then turns off the Backup mode for that tablespace. This process is repeated for each tablespace, and each copy command puts the status of the copy operation to hbackup.log and reports any errors to the herrors.log file.

Listing 3.14 is generated based on the structure of the database. In a real environment, the database structure changes as more data files or tablespaces get added. Because of this, it is important to generate the backup commands dynamically, as shown in hotbackup_list.sql. It performs the actual backup and is called from hotbackup_nt.bat.

Listing 3.14 hotbackup_list.sql

set termout off heading off feedback off

  • Verify that CONNECT_USER is set to the correct username and password.

  • Be sure that the user running the program has Write access to the backup directories.

  • Edit the parameter file to your specific requirements. Specify the full path of the location of your parameter file in the program.

  • When you run the program, pass SID as a parameter.

Export under Windows NT Troubleshooting and Status Check

The log file specified in the parameter file contains detailed information about each step of the export process. This is a very good place to start investigating why an export has failed or for related errors.

A single line about the success or failure of export is appended to the SID.log file every time an export is performed. This file is located under the directory defined by the LOGDIR variable. The messages for an export are 'EXPORT_FAIL', if the export failed, and 'Export Completed successfully', if the export completes successfully.
