Others are covering the DB2 engine for z/OS, but I'll work on the other
items...

DB2 performance monitors need to be associated with the engine you're
running.  So switching from DB2/MVS to DB2/UDB would require changing
your DB2 performance monitors.

Security changes also.  Unless you have a global security product that
may have a DB2/UDB feature (most likely, chargeable), you may have to
have a separate but equal product.  I don't know if RACF has this
feature or not.

Applications really don't know the difference.  No DB2 Connect is
required.  There is a module, ARISDIRD (in the VSE world), which
identifies the databases, and the connection method to get to them.  You
will now be a client, using TCP/IP to a remote database.  And you can
also still have access to your current databases.  Just keep the
database alias names different.

However, some applications "MAY" see some differences.   An "order by"
for example.  DB2/UDB is ascii.  The ascii sort sequence is different.
Does it matter?

Also, going to zLinux, where it is still on the mainframe, is outside
of the "mainframe" world.  Backups, scheduling, TAPE, console
monitoring....all very primative compared to what we are use to.
Solvable...yes..  Can I share the same hardware/software that I'm use to
using?  Not really.  You can piece together things to make stuff work.
Just don't consider retiring or leaving.  No one else may be able to
support the method you put in (using spit, bubble gum and some duct
tape<G>).

My point it that it is a different world.
If you were around mainframes in the '70s, going to zLinux is about the
same.  But back in the '70s, we didn't know we needed/wanted......

Just go in with your eyes wide open.
There are more "costs", then the IFL, zLinux and DB2/UDB.
But there is a lot of neat stuff there also.

At present we have DB2 on Z/OS, collecting information on putting DB2
on
Linux zseries. So that our company can save money on Z/OS cpu
cycles(or
MIPS).

On our mainframe we have OMEGAMON,CICS,RACF,TSO and PLATINUM tools are
accessing DB2 database. If we do migrate to DB2UDB on LINUX zseries,
then
how does the above tools can communicate to newer DB2UDB. Do we need
any
product like DB2 Connect ? was this do able ? any known problems ? I
am
looking for expertise advice on this.

Does still our old COBOL/CICS programs can still acess newer DB2UDB ?
Do we have to do any special binds ?
How was the DB2UDB performace on Linux z-series ?

We are looking for solution that can work seamless solution and no
code
changes
Appreciate all your help.


Thanks
