SYMPTOMS

GG Extract/Pump runs fine for hours or days and then the below error occurs, which causes the Extract/Pump to abend. This error occurs intermittently.

 ERROR OGG-01232 Receive TCP params error: TCP/IP error 104 (Connection reset by peer).

Network teams have found no informative errors in logs on either source or target boxes. 

GG extract/pump has to be manually restarted.
 

CAUSE

Extract/Pump uses STREAMING mode by default
Most of the tcp-ip errors are treated fatal and results in an immediate abend. 

i.e.
 OGG-01232 Receive TCP params error: TCP/IP error 104 (Connection reset by peer).
 
In STREAMING mode communication between extract and the collector is 
 asynchronous. Extract does not wait for an acknowledgement before sending 
 subsequent messages. When an error occurs in STREAMING mode, extract does 
 not know at which point it should resend data, so an error is deemed fatal.
 

SOLUTION

OPTION 1: Use the NOSTREAMING option if hitting tcp/ip errors too often

 In NOSTREAMING mode communication between extract and the collector is 
 synchronous; extract can only send out new data after it receives an 
 acknowledgement of the previous data from the collector. If an error occurs, 
 extract can simply resend the last transmission. 

NOSTREAMING – will make the data pump more resilient to transient network outages

OPTION 2
add AUTORESTART to the manager prm file
to have all pumps restart when it gets a TCP/IP error

AUTORESTART < process type> , RETRIES .., WAITMINUTES .., RESETMINUTES ..

i.e 
AUTORESTART EXTRACT *, RETRIES 3, WAITMINUTES 5, RESETMINUTES 60 
 
You will need to decide which values work best for you
