11g 怎么开归档,多租户就怎么打开归档就好了。
APPLIES TO: Oracle Database - Enterprise Edition - Version 12.1.0.1 and later Information in this document applies to any platform. GOAL Running 12c database and need to configure archive log,shall we configure it in PDB or CDB? SOLUTION All PDBs share the same redo log files,so it's not possible to enable archivelog mode only for a specific PDB. All PDBs share the archivelog mode of CDB. Remember that PDBs themselves don't have a dedicated instance (processes and memory areas) so they share CDB's ones. Configuring of archivelog mode should be implemented in CDB. For more details on how to configure this feature,please refer to below doc: 测试 <roidb01:cdb1:/home/oracle>$sqlplus / as sysdba sql*Plus: Release 12.1.0.2.0 Production on Sat Mar 10 12:34:59 2018 Copyright (c) 1982,2014,Oracle.
