From Datamation, October 15 issue, page 13:

"... Notably absent so far from [DB2] has been an effective record-level
locking feature that is critically important for performing simultaneous
updates to a single database."

And we thought that only Unix DBMS's had problems with record locking :-)

	Also from that same article, it reports that DB2 is averaging
3 to 5 transactions per second on a mainframe. It goes on to quote the
same sources as saying they see 80 tps from IMS. The last numbers I saw
for Ingres on a supermini indicated it could handle around 10 tps.
