DB2 FOR LUW / DB2FORLUW / A50 - DB2

db2top utility when used in background replay mode does not 
generate an output file if the captured snapshot file contains 
only one iteration of data. 
 
Reproduction : 
 
Gathering the snapshot using the following command will have 
db2top run in collector mode for 2 minutes duration and collects 
snapshot data every 2 minutes ( 120 seconds) thus gathering only 
one iteration of data: 
 
db2top -d sample -f db2snap-sample-AIX64.out -C -m 2 -i 120 
 
When trying to read this stream in background mode, it yields no 
output in file "myoutput" below. In fact, the output file is not 
created. Notice the absence of messages relating to the output 
file: 
 
$ db2top -d sample -f db2snap-sample-AIX64.out -b l -o myoutput 
*** End of input stream reached, size was 20696821... 
Exiting...

Run db2top in collector mode longer ( or with shorter interval 
such as using its default 2 seconds interval ), so that there 
are at least two iterations of snapshot stream data were 
collected.
