Interfacing Oracle with Windows scripts Oracle Database Tips by Donald Burleson

Veterans of UNIX (Solaris, HP/UX) and Linux knows that these environments offer superb environments for writing automated procedures (ksh, bash, etc.).  However, we are more limited in Windows when we want to create scripts that interface with Oracle.  There are many third-party tools (e.g. SFU, Windows Services for Unix), but it can be handy to be able to invoke Oracle from a standard DOS command list file.

This blog notes the DOS command line interface to Oracle in this Windows bat file executable:

@ECHO off
SET DBUser=%1
SET DBPass=%2
SET DBTNS=%3
SET LOG=\temp\test\

ECHO spool %LOG%OraCall.log                                 > %LOG%OraCall.sql
ECHO set linesize 132                                      >> %LOG%OraCall.sql
ECHO COL x_tns      NEW_VALUE v_tns      NOPRINT           >> %LOG%OraCall.sql
ECHO COL x_dbid     NEW_VALUE v_dbid     NOPRINT           >> %LOG%OraCall.sql
ECHO COL x_dbname   NEW_VALUE v_dbname   NOPRINT           >> %LOG%OraCall.sql
ECHO SELECT '%DBTNS%'  x_tns      FROM dual;               >> %LOG%OraCall.sql
ECHO SELECT dbid       x_dbid     FROM v$database;         >> %LOG%OraCall.sql
ECHO SELECT name       x_dbname   FROM v$database;         >> %LOG%OraCall.sql
ECHO @SQLSelect.sql                                        >> %LOG%OraCall.sql
ECHO spool off                                             >> %LOG%OraCall.sql
ECHO exit                                                  >> %LOG%OraCall.sql
sqlplusw -s "%DBUser%/%DBPass%@%DBTNS%" @%LOG%OraCall.sql   > %LOG%OraCall.lst

The trick is that the SQL*Plus invocation spool the output on a single command line:

sqlplusw -s "%DBUser%/%DBPass%@%DBTNS%" @%LOG%OraCall.sql   > %LOG%OraCall.lst

For working Oracle Windows Scripts, Jeff Hunter, author of "Conducting the Java Job Interview" has working Windows Oracle scripts here, including JavaScript/Oracle and visual basic/Oracle interface scripts:
 

Script Name

Template.js

Template.vbs

export_backup_online_full_9i.bat

oracle_ADO_example.vbs

rman_backup_hot_full_9i.bat

rman_copy_purge_backupset_9i.bat

sp_purge_n_days.vbs

 

Lets examine Hunter's export___.bat Oracle Windows script.  Note that he builds the exp parfile arguments into a DOS variable called %PARFILE%, just like you can invoke Oracle directly from the DOS prompt (on one line only) : e.g.    

c:> exp=%PARFILE%:
