Hi Everyone, I ran a multi-threading program to make multiple calls to the RPC server. For calls to the natural sub-programs with small Parameter Data Area, they are all successful. However, for calls to the natural subprograms with large PDA, many (NOT all) of the calls weren’t successful. Here are some of the errors I received: Thread 1 - RPC Error : 00010018: Invalid Memory provided. Location of wrong Parameter is 14. Thread 8 - RPC Error : 10146974: NATURAL RPC Server Error 6974 occurred. Thread 3 - RPC Error : 00370042: ATTR: BUFFER-LIMIT for Service reached. Thread 4 - RPC Error : 00370042: ATTR: BUFFER-LIMIT for Service reached. Thread 5 - RPC Error : 00370042: ATTR: BUFFER-LIMIT for Service reached. … We also ran similar program using JAVA RPC with the same EntireX/RPC settings, and it worked pretty well although it occasionally gave the “ATTR: BUFFER-LIMIT for Service reached.” error. We are using EntireX 7.1.1 patch 30/VS.NET 2000/Windows 2000 for the client and Natural RPC Server 5.1.1.0 on VSE. Does anyone know what caused the problem here and how to fix it? Thanks, Chuong ---

The Broker you are using has various parameter settings in the Broker Attribute file for resources the service can use. The buffers you need to adjust are either the SHORT buffers (if your message is under 2k) or, more likely in your case, LONG buffers - you can use the System Management Hub to verify which you are using and how many (see the high water marks) have been used. The number of concurrent messages, conversations in process at the same time will determine the number of buffers required. The default limit for long buffers for a service is 20. If your message is 15k, you will need 8 buffers (and twice that if the message is 15k each way) for each message. ---

There are actually two different issues here: The 00370042: ATTR: BUFFER-LIMIT for Service reached error. Douglas already described how to handle this. The other 2 errors are due to a multi-threading problem in the .NET Wrapper. This problem has been corrected with EXX 7.1.1 PL 55. I suggest to install PL 60 which is a cumulative patch for all components (like PL 30). ---

Douglas and Rolf - We really appreciate your help. From your previous suggestions, we upgraded our EntireX client to patch 60, and it did solve some of the problems. However, even though we increased significantly the values of some of the parameters in the EntireX Broker Attribute file, if we run more than 40 threads, approximately 5% of the calls were still giving error code of 0037-0042. In some cases, it even crashed the server, or produced such error codes as 2002-0000, which we could not even find it in the documentation. Meanwhile, with the same settings, I was able to run successfully a java program with 100 threads making more calls and with some larger PDAs. I’ve been struggling for 2 weeks trying to solve this problem, but have not been successful. So, I am posting here as much info as I could, and hopefully, someone will be able to point out what’s wrong. Thank you very much in advance for your help. Best Regards, Chuong ---

It’ difficult to tell why your .NET application receives the 0037-0042 while the Java one does not. Looking at you attribute file I have a few suggestions: - replace LONG-BUFFER-DEFAULT=200 with LONG-BUFFER-DEFAULT=UNLIM - replace SHORT-BUFFER-DEFAULT=1000 with SHORT-BUFFER-DEFAULT=UNLIM Check with SMH/Control Center the high water marks for these parameters to see if the maximum still needs an increase. I would also set NUM-SERVICE to a much smaller value, this will reduce significantly the memory needed by the Broker. I would also reduce NUM-WORKER, usually 2-4 is a good choice. The error 2002-0000 is documented at least in the 711.PL30/PL60 documentation. This is an internal error, basically telling that an unexpected error situation occurred. According to other customers the 7.2.1 version of the .NET Wrapper seems to be more performant and robust. In case you are already using .NET Framework 1.1 (which is a pre-req for 7.2.1) you might consider upgrading to 7.2.1 (and don’t forget to download/install hotfix 2). ---
