In this blog I want to show you, why you should upgrade to the latest NTCLUST.SAR package from SAP which contains a brand, new cluster resource DLL called "saprc.dll".
The new saprc.dll is completely redesigned and doesn't use any code from the old implementation.
Please see SAP note 1596496 http://service.sap.com/sap/support/notes/1596496 for detailed information where to get the DLL and how to upgrade it?
The version of the DLL and the tool insaprct.exe can now be seen in Windows File Explorer, right mouse click on the DLL, navigate to "Details" and detailed information is displayed.
We add several new property fields to the SAP instance cluster resource:
You can start your own batch files here!
Example:
If there will be a failure with this SAP instance, saprc.dll will start a script in c:\scripts\failure.cmd. With this script (must be written from you!) you can send a mail, an SMS, send an alert to a monitor of your choice, etc.
Additionally, the error handling in version 404 was greatly enhanced! If for whatever reason the communication between saprc.dll and the SAP start service (sapstartsrv.exe) is not working using the named pipe protocol, we will now switch to https or http as failback protocols. This will be logged to cluster.log and Windows event viewer application log.
==========================================================================
The new Enqueue Replicator 2 is now fully supported.
enhanced error descriptions in case of named pipe problems.
==========================================================================
New parameter in SAP instance resource “IgnoreYellowTime”. This can be switched on or off which does not requires a restart of the resource. The parameter means: “Ignore any yellow state of a process started by sapstartsrv.” This can solve problems in cluster environments which have high load situations where one of the central processes report “yellow”, because it’s currently busy.
Example:
==========================================================================
How can I find out, if I have a new saprc.dll in place?
Start Windows File Explorer, right mouse click on c:\windows\system32\saprc.dll and you see the version:
The latest version is 5.0.0.0
