Failed to load Model

Question

Hi, i create a couple of models in the folder public, i've been working with some errors, sometimes when i try to open any of the models, gives an error: "Failed to load Public/exmodel.mdl model: provider org.apache.xerces.jaxp.DocumentBuilderFactoryImpl not found", but i've found that if i restart the server the problem it's gone, any ideas??
Thanks,
Sergio

Answer 1

The reason for this is that there is a slight difference in
Informix 7.30 and 7.31 (and even between 32 and 64 bit)
for the master table definitions for SYSPTNTAB.
To work around this issue
connect <user>/<passwd>; (Oracle8i repository owner)
create table ids7_sysptntab_bu as select * from ids7_sysptntab;
alter table ids7_sysptntab
add ( addresspad number(10,0), condpad number(10,0),
latchpad number(10,0), lastrowszpad number(10),
lastrowpnpad number(10,0), extnspad number(10,0),
ptlistpad number(10,0), localepad number(10,0) );
