Same Map Dependency Issues

[clk430]

We have a generic router map that is basically 1 input, 1 output, input=output. It is called generic.mms/generic.mmc. We use it in almost all of our systems, unrelated and related to have a basic I/O map and more so, to use the batch output adaptor in the IFD to call external batch scripts/executables.

My question is, if a system that uses this map gets hung (say, the executable that the batch script it calls fails and the map does not complete), could all other instances of this generic map get hung as well? Is this poor design to have so many systems dependant on one generic map?

In other words, System ABC.msd uses generic.mms to call encrypt.exe. System XYX.msd uses generic.mms to call zip.exe. If the generic.mms is hung in ABC, will XYZ be effected?

Each Event Server (I am assuming you are using UNIX or multi-process Event Server) will have a separate image of the map in memory.

We are using a Windows 2000 OS with 1 CPU on Mercator 6.7. Should I assume we don't qualify?

If you are in a single Event Server, and it hangs, it is hung.
It might be possible to have one map hang and other keep processing, since each call to a map is it's own instance and thread, as long at there is no threading conflict.

Each map instance runs in it's own thread.

Or, if this generic map has two outputs, one of which is written to the same, hardcoded file in the IFD settings? eg. mercatorlog.txt I assume this file creates a contention and if all other generic maps in other threads point to it, then they will all hang.

I've learned a lot in this thread. Thanks Boca.

Anonimity? You run Windows. The last .wmf you played has sent me your passwords, your social security number, your address and the name of your dog

It's time to change the oil in your car and check the air pressure in your right rear tire, too
