There are many things cause the error such as :
1. Your Broker Service is not yet running (default : wsbroker1)
run with this script for UNIX :
- proadsv -start
- nsman -name wsbroker1 -start
- wtbman -name wsbroker1 -start
- wtbman -name wsbroker1 -query (to see the query / status )
2. Your database is not up status
3. You may be change structure (table) in your database, but you don't recompile your program, it can be cause the error display.
thx.
