Alexey Popov created IGNITE-6835: ------------------------------------ Summary: ODBC driver should handle ungraceful tcp disconnects Key: IGNITE-6835 URL: https://issues.apache.org/jira/browse/IGNITE-6835 Project: Ignite Issue Type: Bug Security Level: Public (Viewable by anyone) Components: odbc Affects Versions: 2.1 Reporter: Alexey Popov
It is found that ungraceful TCP disconnect makes ODBC driver stuck at socket recv(). Ungraceful TCP disconnect could be caused: 1. Network failure (or new firewall rules) 2. Remote party shutdown (Half Closed Connection) So, the proposal is: setup socket options: 1) SO_KEEPALIVE enabled 2) TCP_KEEPIDLE to 60 sec. It is 2 hour by default 3) TCP_KEEPINTVL to 5 (?) sec. It is 1 sec at Win and 75 sec at Linux by default. 4) send/receive buffers to some greater value (8k by default) -- This message was sent by Atlassian JIRA (v6.4.14#64029)
