Hello, Glad to see progress on this, much needed.
I wonder if there is a better way for safe and dynamic string concatenation in the JDK, this errmsg[56] looks scary. Did you tried to support it on Windows, even if it does not support all 3 parameters it might be important to be available (I think Oracle Database supports it for DCD on Windows, too) Gruss Bernd Gruss Bernd -- http://bernd.eckenfels.net ________________________________ From: net-dev <net-dev-boun...@openjdk.java.net> on behalf of vyom tewari <vyom.tew...@oracle.com> Sent: Friday, April 13, 2018 11:50:39 AM To: OpenJDK Network Dev list Subject: RFR:8194298 Add support for per Socket configuration of TCP keepalive Hi All, Please review the below code. BugId : https://bugs.openjdk.java.net/browse/JDK-8194298 webrev : http://cr.openjdk.java.net/~vtewari/8194298/webrev0.0/index.html Currently Java supports SO_KEEPALIVE, whose default value is 7200 seconds which is too long for most of the applications. This code change will allow us to set the keepalive parameters(TCP_KEEPIDLE,TCP_KEEPCNT,TCP_KEEPINTVL) which will configure the idle time on per socket basis. I did code changes for Linux & Mac only, support for other platforms can be added in future if needed. Thanks, Vyom
