As promised in prior message, here are those items on latest "Now /
Soon Available in Image/SQL" list that were still in "SOON" or "BETA"
status at HPW-01 in Chicago.  Several of these items are already
done; and are only awaiting an appropriate release vehicle; others are
close to being done / in beta test (no: I haven't had time to check very
latest status for each individual item).  I believe all of the following are

either available now as patches;  or will be in MPE 7.5;  or will be
available as patches before or about the time 7.5 hits the street;  i.e.:
We don't have to vote for any of these again, because they are (still)
going to be delivered by CSY (thank you to R&D Database Lab
engineers in both Cupertino and Bangalore)....

================================================

"Now / Soon Available in Image/SQL"

1.  DDX functionality with Large Files in TurboIMAGE:

2.  Use MPE Large Files to get > 4 GBytes in one dataset, instead of
     using more JUMBO "chunk files":

3.  DBUNLOAD / DBLOAD to / from both tape and DISC:

4.  Utility to allow "semi-in-place" migration of datasets from JUMBO
     chunk files to MPE "Large Files":

5.  ONE-time make DBUTIL DUMPING and DSEM flags default =
     ENABLED:

6. "Scalability Phase II":  Divide multiple DBPUT - DBDELETE
     semaphores (DSEM) down to BLOCK level:  Lock data blocks;
     then release semaphore.  Activate with  DBUTIL ENABLE base
     FOR EHWM (extended high-water mark):

7.  Increase Allbase limits: Runtime control block # of pages:  2000
     to 6000;  # of concurrent transactions:  250 to 750:

8.  Ability to add session name as user identifier in IMAGE log file;
     to differentiate users with same logon.  Activate with  DBUTIL
     ENABLE base FOR FORCESESSION:

9.  IMAGESQL ATTACH command options:  NOAUTOS (skip AUTO
     Masters) and NOAUTOSPLIT (for IMAGE compound items):
