I guess you have two questions and I can answer the first one and take a
stab at the second...
First question, RPC gems inherit the environment variable from the
netldi, so any env vars you want the RPC gem to see need to be set
before starting the netldi. If you are running a linked gem (i.e.,
topaz) the environment variables are inherited from the process starting
The second question (log everything in one spot) is why I asked the
version question, because I seem to recall that there are cases where
not all logs got handled correctly, but as I think about it the problem
areas may have been relatively special cases and/or version specific
bugs. I'll wait until you get the basic logging working with
GEMSTONE_NRS_ALL before digging deeper.
As shameless a plug for using GsDevKit_home, you can set custom env vars
in a per stone custom_stone.env. As Mariano mentions GEMSTONE_LOGDIR
defines the log location and here is the NRS expression used:
The custom_stone.env script is executed before starting your netldi,
when using startNetldi and before starting a topaz session when using
startTopaz. You can use GsDevKit_home without having to use tODE or
extent0.seaside.dbf. Currently to create a stone that uses extent0.dbf
you would do the following:
createStone -g -s
I've got a release in the "oven" that simplifies the creation process:
createStone -G gs_329 3.2.9
