OGG-00665 OCI Error executing single row select(status = 3135-ORA-03135: connection lost contact

【现象】:oracle端goldengate的抽取进程状态为abend,但mgr和投递进程为running状态

【排查】:1、查看抽取进程的dsc日志文件,无记录

                    2、查看ggserr.log,报“2014-01-17 18:25:56  ERROR   OGG-00665  Oracle GoldenGate Capture for Oracle, ex_xxxx.prm:  OCI Error executing single row select (status = 3135-ORA-03135: connection lost contact
Process ID: 2520
Session ID: 351 Serial number: 9), SQL<SELECT DECODE(archived, 'YES', 1, 0),       status  FROM v$log WHERE thread# = :ora_thread AND       sequence# = :ora_seq_no>.”错误日志提示抽取进程与oracle的连接断开

                    3、查看oracle的alert日志,显示goldengate报错时,数据库进行了shutdown操作。

【分析】:抽取进程abend的原因是,oracle数据库关闭,导致抽取进程与oracle的连接中断,所以抽取进程abend了,但投递进程和mgr进程正常。

【解决】:启动抽取进程即可,也可在mgr中配置抽取进程autorestart,使其自动启动
