Hi,

This is one of the strangest things that I have seen in years.....

We have an SAP/Oracle system running on Win2003/SP2 (Xeon CPU). (For
those interested, it is SAP R3 v47 running on Oracle 9i).

There were about 10 or so SAP related registry entries in
HKEY_LOCAL_MACHINE - SOFTWARE - SAP -
(SAP System ID) - Environment

A few days ago, I stopped SAP and Oracle to make a config change.
Oracle started well, but SAP
had various difficulties starting. To my amazement, virtually all of
the registry entries in
"HKEY_LOCAL_MACHINE - SOFTWARE - SAP - (SAP System ID)- Environment"
were missing.

I fixed SAP's startup issues by adding the necessary entries to the
registry and/or env. variables.

We have Norton scanning daily. It did not display any recent problems.
The event log
also displayed nothing of significance.

What could have caused these registry entries to disappear, or appear
to disappear ?
(Perhaps some were not registry entries, but env. variables, but most
were registry entries).

It does not seem like a virus, or something similar, because Windows,
Oracle, etc..
were fine.

Any ideas will be greatly appreciated.




Thanks,
DF
