标题：ogg导致v$logfile查询频繁

在某些版本的ogg中发现ogg抽取进程对v$logfile视图查询影响比较大
20181116220104

对应的sql语句为:SELECT 1 FROM V$LOGFILE WHERE(STATUS NOT IN (‘STALE’, ‘INVALID’) OR STATUS IS NULL) AND MEMBER <> :log_name AND EXISTS ( SELECT 1 FROM V$LOG WHERE GROUP# = V$LOGFILE.GROUP# AND THREAD# = :ora_thread AND SEQUENCE# = :ora_seq_no ) AND ROWNUM = 1
查询mos发现相关问题描述:Query On V$logfile Running Excessive Number Of Times After upgrading ogg to 11.2.1.0.32 or 12.1.2.1.5 or later (Doc ID 2116395.1)和Bug 22650790 : CE 12.1.2.1.9: Query on v$logfile running excessive number of times
2116395.1
根据mos描述在ogg对应版本中设置:TRANLOGOPTIONS _ENABLESTREAMLINEDDBLOGREADER
