随着Oracle19c 被越来越多的客户使用，pdb 模式越来越多，如何更好更快速的检查他们的信息呢，Oracle12c以后多了一个cdb_开头的视图，来进行统一检查。 下面节选几个常用命令 #### PDB检查 ``` sql --查看pdb信息 or dba_pdbs set lines 160 col name for a20 col open_time for a40 select con_id,dbid,name,open_mode,open_time,creation_time from v$pdbs; --查看CDB部分信息 set lines 160 col con_name for a30 select c.con_id,c.name con_name,t.tablespace_name,t.contents,t.status from v$containers c,cdb_tablespaces t where c.con_id=t.con_id and t.contents='UNDO' order by 1,2; --跟随CDB启动 alter pluggable database firsoul01 save state; --查看每个pdb大小 select c.name,round(sum(s.bytes/1024/1024/1024),2) size_gb from cdb_segments s,v$containers c where c.con_id=s.con_id group by c.name order by 2 desc; --连接 or tnsnames alter session set container=orclpdb; --查看pdb的服务名 col pdb for a15 col name for a20 col network_name for a20 SELECT PDB, name,NETWORK_NAME, CON_ID FROM CDB_SERVICES WHERE PDB IS NOT NULL AND CON_ID > 2 ORDER BY PDB; --查看历史pdb信息 col db_name for a15 col pdb_name for a15 col CLONED_FROM_PDB_NAME for a20 SELECT DB_NAME, CON_ID, pdb_id,PDB_NAME, OPERATION, OP_TIMESTAMP, CLONED_FROM_PDB_NAME FROM CDB_PDB_HISTORY WHERE CON_ID<>pdb_id and pdb_id>2 and db_name=(select name from v$database) ORDER BY PDB_ID; ``` #### 表空间管理 ``` sql --查看表空间 break on name skip 1 col name for a20 col tablespace_name for a30 set linesize 200 pagesize 500 select c.name name,f.tablespace_name tablespace_name, round((d.sumbytes/1024/1024/1024),2) total_without_extend_GB, round(((d.sumbytes+d.extend_bytes)/1024/1024/1024),2) total_with_extend_GB, round((f.sumbytes+d.Extend_bytes)/1024/1024/1024,2) free_with_extend_GB, round((d.sumbytes-f.sumbytes)/1024/1024/1024,2) used_GB, round((d.sumbytes-f.sumbytes)*100/(d.sumbytes+d.extend_bytes),2) used_percent_with_extend from (select con_id,tablespace_name,sum(bytes) sumbytes from cdb_free_space group by con_id,tablespace_name) f, (select con_id,tablespace_name,sum(aa.bytes) sumbytes,sum(aa.extend_bytes) extend_bytes from (select con_id,nvl(case when autoextensible ='YES' then (case when (maxbytes-bytes)>=0 then (maxbytes-bytes) end) end,0) Extend_bytes ,tablespace_name,bytes from cdb_data_files) aa group by con_id,tablespace_name) d,v$containers c where (f.con_id=d.con_id and f.tablespace_name=d.tablespace_name) and f.con_id=c.con_id order by name,used_percent_with_extend desc; --查看所有数据文件 break on cdbname skip 1 set lines 200 pages 999 col cdbname for a10 col dbfile for a80 select c.name cdbname,d.file# dfile,d.name dbfile,round(f.bytes/1024/1024/1024,2) size_gb,f.AUTOEXTENSIBLE ,d.CREATION_TIME from v$datafile d,v$containers c,cdb_data_files f where c.con_id=d.con_id and d.name=f.file_name order by cdbname,d.creation_time; ``` #### 用户管理 ``` sql --查看每个pdb下用户大小 break on pname skip 1 col owner for a20 col pname for a15 select c.name pname,s.owner,round(sum(s.bytes/1024/1024/1024),2) size_gb from cdb_segments s,v$containers c where c.con_id=s.con_id group by c.name,s.owner order by 1,3 desc; --查询用户名、锁定状态、表空间、配置文件、权限--- break on cname skip 1 set pagesize 999 set linesize 150 col cname for a20 col username for a25 col ACCOUNT_STATUS for a20 col DEFAULT_TABLESPACE for a20 col PROFILE for a20 alter session set nls_date_format='yyyy-mm-dd hh24:mi:ss'; select v.name cname,c.username,',',c.ACCOUNT_STATUS,',' ,c.DEFAULT_TABLESPACE,',',c.PROFILE,c.CREATED from cdb_users c,v$containers v where c.con_id=v.con_id order by v.name,c.created; ``` 其他可以参考以上语句，cdb开头视图 结合v$containers ，列出pdb的命令，再个 可根据自己喜好，可以选择排除种子pdb、cdb等输出。
