Hi,
Environment used:
Postgres 8.3.1
psqlODBC 08.03.0200
Testcase:
In the postgres database there is table 'COUNTER_TABLE' with column integer type 'COUNTER'. The test application attached in this mail, will start a transaction, gets the current value in the COUNTER, increments the value and updates the incremented value into the COUNTER column. This is being done in a loop. The program is started in a remote client and after few transactions, the interface between the client & the database server is brought down (example I used "ifconfig eth0 down" in the server). With this the test application hangs and does not return from the API of postgres (ex. 'PQexec').
<<pg_test_app.cpp>>
In another example, run the psql from the remote client and connect to the database server. Execute the SQL to update the COUNTER_TABLE. After successful execution, next bring the network interface down on the database server (Ex. I use the command "ifconfig eth0 down") and next execute the SQL command to update the COUNTER_TABLE again from the same remote client and the same DB session. The SQL command hangs.
regards,
Niranjan
