Why Registry Entries Disappeared

[Guest basis_consultant@hotmail.com]

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
