Intermittent connection errors

We have a Big-Ip VIP fronting our two-node Oracle RAC. All too frequently we get application connection errors when connecting through the VIP. The nodes are fine and connecting directly to them works...

Hi Chris, Rcorder,

 

 

First of all thanks for your help !

 

 

I will try to start sniffing the traffic today...

 

 

These are the parameters in the sqlnet.ora file:

 

NAMES.DIRECTORY_PATH= (TNSNAMES)

 

TCP.CONNECT_TIMEOUT=10

 

SQLNET.EXPIRE_TIME=10

 

 

In the several tests I've made, I've also tried setting SQLNET.EXPIRE_TIME=0 (to try with the connections left open indefinitely) but still the same...

 

I've also added a screenshot of the client tcp profile... I had unchecked the 'Reset On Timeout' to avoid the RST but I will check it again...

 

 

BR,

 

 

Phil
