I don't know if it's just me or what, but if I write a very simple multitasking client program and have both tasks send RPC's (both tasks are in a loop issuing RPC's) to the same server, the server usually starts hogging the CPU after about 3 minutes of reliable service. In general, I have found AdaLan to be quite unpredictable when incorporating Adalan-based RPC's into a multi-tasking client. In fact, AdaLan comes with an example program that demonstrates how to write the client (stub and application) and server code when the client is multi-tasking. Even this "canned" example (slightly modified to send a steady stream of RPC's to the server) didn't perform up to expectations; the server started hogging the CPU after about 3 minutes for no apparent reason. My main goal is (or was :-) to use the RISCAda compiler with TeleLan and a TeleSoft Motif GUI builder called "TeleUSE." Problems only multiply when TeleUSE is brought into the picture. The good folks at TeleSoft assured me that some of their customers use these three products together with success. Has anybody had any luck with the combination of these three products? Inquiring minds would love to know!! -- ----------------------------------------------------------------------- | Victor Krawczuk (e-mail : victor@cs.concordia.ca ) | | Concordia University, Dept. of Computer Science (H-961) | | 1455 De Maisonneuve Blvd. W., Montreal, Quebec, Canada, H3G 1M8 |
