Informix - Problem description

Problem IT04416 Status: Closed

INFORMATION REGARDING THE MAXIMUM VALUE OF TAPESIZE PARAMETER IS NOT THE
SAME IN ALL THE INFORMIX DOCUMENTATION

product:
INFORMIX SERVER / 5725A3900 / B50 - IDS 11.50
Problem description:
The information in the "TAPESIZE configuration parameter" link 
of infocenter for IDS 11.50, 11.70 and 12.10 shows : 
 
TAPESIZE configuration parameter 
 
Use the TAPESIZE parameter specifies the size of the device to 
which ontape backs up storage spaces. 
 
onconfig.std value 
    0 
units 
    Kilobytes 
range of values 
    0 or any positive number. The real value operating system 
dependent. 
 
we can see the above information in the following links :

ibm.bar.doc/ids_bar_525.htm?lang=en 
 
 
However in the information to "Specify the tape size" we have 
that the range to configure TAPESIZE is from 0 to 2,097,151. 
 
Use the TAPESIZE and LTAPESIZE configuration parameter 
parameters to specify the maximum amount of data that you can 
write to a tape. 
 
To write or read the tape to the end of the device, set TAPESIZE 
and LTAPESIZE to 0. You cannot use this option for remote 
devices. 
 
When you specify the tape device as /dev/null, the corresponding 
tape size is ignored. 
 
The range of values for these parameters is 0 - 2,097,151. 
 
we can see the above information in the following links : 
 
http://www-01.ibm.com/support/knowledgecenter/SSGU8G_11.50.0/com 
.ibm.bar.doc/ids_bar_301.htm?lang=en

http://www-01.ibm.com/support/knowledgecenter/SSGU8G_12.1.0/com. 
ibm.bar.doc/ids_bar_301.htm 
 
Per development the correct value is 0 to 2,097,151, it is not 0 
to any positive number.
