Sqlplus works with a linelength that, by default, is 80 characters.
This looks like the reason for the text being split.
Try adding the following line to the top of the hotbackup sql script:
set linesize 500
If 500 is not wide enough, you can increase the value still further,
up to several thousand if necessary.
As you can see from the following code snippet (prints a line of 90
stars, both with a line size of 80 and then 500), this will resolve
your issue:
Code:
set linesize 80
begin
dbms_output.put_line(LPAD('*', 90, '*'));
end;
/
set linesize 500
begin
dbms_output.put_line(LPAD('*', 90, '*'));
end;
/
Output:
SQL> set linesize 80
SQL> begin
SQL> dbms_output.put_line(LPAD('*', 90, '*'));
SQL> end;
SQL> /
********************************************************************************
**********
PL/SQL procedure successfully completed.
SQL> set linesize 500
SQL> begin
SQL> dbms_output.put_line(LPAD('*', 90, '*'));
SQL> end;
SQL> /
******************************************************************************************
PL/SQL procedure successfully completed.
Note that email line wrapping may bork that output a bit in
transmission, but you should also be able to see that the second set
of stars is on fewer lines than the first. Try it in your own
sqlplus session to see the difference for yourself!
I would add an extra couple of points of interest here:
1. You may wish to consider adding:
set trimspool on
at the top as, by default, each line is padded to the line width,
making for a much bigger file.
2. If you have a lot of files and tablespaces to process, it is
possible that the buffer size of 20000 set up at the top (in the
call to dbms_output.enable(20000)) is not big enough. I would
suggest increasing this value to 2 million, which is the maximum
value allowed. I've also go no idea why this is run as a separate
exec call at the top, rather than as the first line of the pl/sql
script!
If I can find how to register as a wiki contributor, I'll update the
page, otherwise somebody else may wish to take on these minor
modifications?
