I've just inherited an Oracle database, and I don't have the first clue as to how to write code for it. I do however know how to search on the web, and have come up with this script.
**********************************************************************
f:
cd Oracle_Backup

REM Column instnc new_value v_instnc noprint
REM column instdate new_value v_instdate noprint
REM SELECT name instnc
REM FROM v$database;
REM SELECT TO_DATE(sysdate,'DDMMYYHH') instdate
REM FROM dual;

exp system/manager@swp
REM file=swp_full&&v_instexp&&v_inst_exp&&v_instdate..dmp
REM log=swp_full&&v_instexp&&v_inst_exp&&v_instdate..log

full=y
**********************************************************************

The REM lines are what I gleaned off another site, and the file and log commands originally looked like:

file=swp_full.dmp
log=swp_full.log

But were changed to this per the borrowed script:

swp_full&&v_instexp&&v_inst_exp&&v_instdate..dmp
swp_full&&v_instexp&&v_inst_exp&&v_instdate..log

So, I can almost follow what is being done in the script, but since I have ZERO Oracle experience, I need help. If you can help me please contact me. I would greatly appreciate it.
