Steve:
If you have the configuration variable persistent restart set to on, then Witango
will read the domain vars from the dump file upon restart. If the server goes
down "improperly" the dump file is not recorded with the latest domain vars.
Therefore, when you restart Witango, it reads the old domain vars instead of the
current ones that were never recorded. We have had this problem for a long time and
decided to turn off persistent restart and let the "restore" logic take over. That
way Witango does not try to read a "bad" set of variables from the dump file and
instead gets them from your db. Hope I understood your problem correctly.

Subject: Witango-Talk: Domain Variables
Win2K sp3 server, R:Tango 2000, R:Base 6.5
I'll try to explain this as best I can. I am having trouble with my domain
variables. When I restart Witango services or it restarts itself, my domain
variables are reset to old values, not the current ones. The current values
are stored in a database table. Are domain variables stored in a cache that
reloads if the service restarts?
This is how my application works. FYI: I have patterned it after James
Carroll's Storefront.
Every time a visitor hits the home page, Default.taf, it checks to see if
the Object Instance Variable <@VAR domain$Common> for catalog.tcf is empty.
If it is, it calls catalog.tcf. The On_Create method calls the method within
itself called InitializeSystemVariables. This method checks a domain
variable <@VAR Domain$Initialized> to see if it is empty. If it is empty, it
reads the database table and resets the variables.
I can manually reset the variables with a method in catalog.tcf called
ReloadSystemVariables which reads a database table of these variables and
sets them up as domain variables. When I run that method, the domain
variables are reset to the current variables in the table.
I assume when the service restarts, that is clears all domain variables. In
particular Domain$Initialized, so when the first visitor hits Default.taf,
the application would reset the variables from the current values in the
table.
Any help would be appreciated.
