ONS sockets associated with port 6101 in a TIME_WAIT status

[Former Member]

Hi Experts,

We have an Oracle RAC 10.2.0.2 installed on RedHat linux 4 update 5 with SAP NW 2004s SR2.

Now we have a typical issue wherein after starting the CRS (specifically after ONS daemon startup) netstat -an reports thousands of sockets associated with 6101 in a TIME_WAIT status as shown below

127.0.0.1.6101 127.0.0.1.55228 49152 0 49152 0 TIME_WAIT

127.0.0.1.6101 127.0.0.1.55229 49152 0 49152 0 TIME_WAIT

127.0.0.1.6101 127.0.0.1.55230 49152 0 49152 0 TIME_WAIT

127.0.0.1.6101 127.0.0.1.55231 49152 0 49152 0 TIME_WAIT

127.0.0.1.6101 127.0.0.1.55232 49152 0 49152 0 TIME_WAIT

This doesn't allow SAP to startup as it also occupies the SAP ports. Only killing the ONS daemon releases this port.

We followed sap note 995013 but in vain. Also applied oracle patch 4518443.

Does anybody have an idea what might be causing this?

Issue resolved. We added an extra parameter in the ons.config file (allowgroup=true).
