In our daily work, one popular question is how to keep our session alive, especially for Oracle session.
I know there is a parameter named sqlnet.expire_time in the sqlnet.ora for such function in the DB server side, but if I want to do similar configuration in the Oracle client, how?
I searched in the Oracle Support website, and found this request could be fulfilled by following ways:
- Add enable=broken in the tnsnames.ora file
- Adjust the tcp_keepalive_interval value in the OS
Please note for the item 1, the option must be placed in the right location, this is to say, it must directly below the ' (DESCRIPTION =' entry as below:
(DESCRIPTION = (ENABLE=BROKEN) ####<<< Place entry here to enable to TCP KeepAlive mechanism
For the item 2, different OS has different way to change it, and you have to find it by yourself.Windows
