Important Note on using Hyperwave backup with SP5! 

Please be aware of the following possible situation after the 
installation of SP5 (all platforms). In scenarios, where a Hyperwave 
native backup is running in combination with a Hyperwave native database 
system the server might have problems during a new start-up. The error 
message from dcserver reads: "no freeze type lock present" and the 
server will stop afterwards.

The error occurs because the dcserver cannot handle a temporary directory 
which is created during the backup. 

If the above scenario is implemented at your site, please use the dcserver 
binary of the SP4 package as the current workaround. If you are experiencing 
the problem, you should delete this temporary directory 
($HOME/dcserver/local/local_.backup) manually and then downgrade to the 
SP4 dcserver binary. The server will afterwards start without problems. 

We have released a hotfix for this situation on Wednesday, 5th July 2000. 
The hotfix consists of a fixed dcserver binary for the native database and 
Oracle. The hotfix is called is511hf16.tgz for Unix and st511hf16.exe for 
Windows NT. You will find it in the same directories as your platform-specific
Service Pack. Please extract the hotfix to the appropriate binaries directory
of your Hyperwave Information Server (e.g. $HOME/bin/SUN5).

If you are not running a Hyperwave native backup you may safely use the 
current SP5 package.
