DB2 FOR LUW / DB2FORLUW / A50 - DB2

in v10.1, an Online Backup may perform poorer then previous 
releases.  Also, there may be an abnormally large variance in 
the size of the backup sequence files. 
 
When more then one tablespace exist, Online Backup will 
parallelize the processing of tablespaces. Before reading 
extents for a tablespace in parallel, Backup must flush dirty 
bufferpool 
pages for this tablespace to disk.  Prior to v10.1 this flush 
was performed in 
parallel by the backup db2bm edus.  In v10.1 this action is 
performed in serial by the backup db2agent edu.  If flushing of 
the bufferpools takes a relatively long time (because the 
bufferpools contain many dirty pages, or there is a lot of other 
concurrent transaction activity) then it will take longer for 
Backup's parallel db2bm edus to begin processing some 
tablespaces. 
 
Also, when more then one path is specified in the Online Backup 
command, this defect can result in abnormally large variations 
in the size of the backup sequence files, usually one being 
much larger then others (small variations are normal). 
 
These problems do not affect releases prior to 10.1.

One potential method to help alleviate the issue is to decrease 
the Backup PARALLELISM value. Another potential method to help 
alleviate the issue is to disable TRACKMOD configuration 
parameter (if you to do not need incremental or delta backups).
