经常在OGG日志文件中看到如下错误：
查了metalink，大概说的是extract 和collector 交互的关系，分为STREAMING 和NOSTREAMING 模式，各有各的优势。总的建议如果该错误不是很频繁，建议使用STREAMING模式。下面贴出原文：

APPLIES TO:Oracle GoldenGate – Version 11.2.1.0.1 to 12.1.2.0.0 [Release 11.2 to 12.1] Information in this document applies to any platform. SYMPTOMSGG 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. CAUSEExtract/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. SOLUTIONOPTION 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 The GG reference has more details about the syntax.
