Problem IT03370 Status: Closed

Input a non-existing big column number in .db2toprc or "c - Change
columns order" during interactive mode can trap db2top

product:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problem description:
When putting a big column number in db2top configuration file, 
.db2toprc. such as following example: 
$cat .db2toprc 
sessions=201012,10 
 
or input a big column number for "c - Change columns order" 
during interactive mode, such as following example: 
sessions= 
Enter new columns order for sessions: 201012,10 
 
Those numbers are column number on db2top displaying screen. The 
large numbers (i.e  201012 ) is bigger than the biggest column 
number on Session screen: 40.

Session screen, db2top traps with following StackTrace or 
similar:

Local Fix:
You should input column number less than 50 for .db2toprc or  "c 
- Change columns order" during interactive mode. 
Also for .db2toprc, another local fix is to comment out that 
configuration line in by adding a '#' at the front.
