Question

Hi,
Is there anybody to reply?
i am using oracle 11g R1 on windows platform.
i am using this in sqlplus prompt . Actually i am using a batch file to change the dump .
DEFINE FILE_NAME=&file_name; -- This will ask the Dump file name as an input.
declare Schema varchar2(20);
begin
select substr('&&file_name',23,instr('&&file_name','0')-22) into Schema from dual; -- this will give the Schema name as an output.
dbms_output.put_line(Schema);
end;
Drop user &&Schema Cascade;--(Now i am facing the problem in this line. I am not getting Schema name to drop)
host imp system/oracle file=&&file_name fromuser=&&Schema touser=&&Schema log=&&file_name --(I am not getting result)
Can u tell me what's the problem in this Script. and is there any other way to achieve the same target?
Thanks & Regards,
Vikash

Answer 1

maybe you could make an enviroment file setting file_name and schema name and make a call process redirecting it to that script with those variables as arguments at the time of calling sqlplus. Like this
enviroment file:
FILE_NAME=file
SCHEMA_NAME=schema
SUPER_SCHEMA=system
SUPER_PASSWORD=system_password
your script:
DEFINE FILE_NAME=&file_name; -- This will ask the Dump file name as an input.
declare Schema varchar2(20);
begin
select substr(&file_name,23,instr(&file_name,'0')-22) into Schema from dual; -- this will give the Schema name as an output.
dbms_output.put_line(Schema);
end;
Drop user &schema_name Cascade;--(
quit
calling script:
call enviroment;
sqlplus %SUPER_SCHEMA/%SUPER_PASSWORD @yourscript %file_name %schema_name
imp %SUPER_SCHEMA/%SUPER_PASSWORD file=%FILE_NAME fromuser=%SCHEMA_NAME touser=%SCHEMA_NAME log=%FILE_NAME --(
i think this is the way to get the arguments inside the script, but im not 100% sure, can anyone confirm this?.
cheers ^^.
