手动建库几乎是每个DBA都需要掌握的技能,而Database 12c中手动创建Container Database容器数据库的过程是如何的呢? 目前12c创建容器数据库Container Database和普通Database存在一点点小的区别,需要指定enable pluggable database,已创建的数据库目前无法转换为容器数据库。 创建必要的目录 mkdir -p /stage/oradata mkdir -p /stage/fr mkdir -p /u01/app/oracle/admin/MACLEANCDB/adump 我们创建 实例初始化文件,并创建DB:     1、 INIT.ORA

      2、 创建密码文件     oracle@localhost:~$ /u01/app/oracle/product/12.1.0/dbhome_1/bin/orapwd file=/u01/app/oracle/product/12.1.0/dbhome_1/dbs/orapwMACLEANCDB force=y extended=y Enter password for SYS:     3、 正式创建DB    
oracle@localhost:~$ export ORACLE_SID=MACLEANCDB
oracle@localhost:~$ sqlplus / as sysdba

SQL> startup nomount pfile='init.ora';
ORACLE instance started.

enable pluggable database;

Database created.

set linesize 2048;
column ctl_files NEW_VALUE ctl_files;
select concat('control_files=''', concat(replace(value, ', ', ''','''), '''')) ctl_files from v$parameter where name ='control_files';
host echo &ctl_files >> /u01/app/oracle/admin/MACLEANCDB/scripts/init.ora;
spool off

将控制文件信息写入到中==》 echo &ctl_files >> /u01/app/oracle/admin/MACLEANCDB/scripts/init.ora;
    4、创建默认使用的USERS表空间  
SQL> CREATE SMALLFILE TABLESPACE "USERS" LOGGING  DATAFILE  SIZE 5M AUTOEXTEND ON NEXT  1280K MAXSIZE UNLIMITED  EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT  AUTO;

Tablespace created.

SQL> ALTER DATABASE DEFAULT TABLESPACE "USERS";

Database altered.
      5、 执行必要的数据字典创建脚本      
alter session set "_oracle_script"=true;
alter pluggable database pdb$seed close;
alter pluggable database pdb$seed open;
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b catalog /u01/ap
p/oracle/product/12.1.0/dbhome_1/rdbms/admin/catalog.sql;
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b catblock /u01/a
pp/oracle/product/12.1.0/dbhome_1/rdbms/admin/catblock.sql;
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b catproc /u01/ap
p/oracle/product/12.1.0/dbhome_1/rdbms/admin/catproc.sql;
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b catoctk /u01/ap
p/oracle/product/12.1.0/dbhome_1/rdbms/admin/catoctk.sql;
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b owminst /u01/ap
p/oracle/product/12.1.0/dbhome_1/rdbms/admin/owminst.plb;
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b pupbld -u SYSTE
M/&&systemPassword /u01/app/oracle/product/12.1.0/dbhome_1/sqlplus/admin/pupbld.sql;
connect "SYSTEM"/"&&systemPassword"
set echo on
spool /u01/app/oracle/admin/MACLEANCDB/scripts/sqlPlusHelp.log append
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b hlpbld -u SYSTE
M/&&systemPassword -a 1  /u01/app/oracle/product/12.1.0/dbhome_1/sqlplus/admin/help/hlpbld.sql 1helpus.sql;
@/u01/app/oracle/product/12.1.0/dbhome_1/sqlplus/admin/help/hlpbld.sql helpus.sql;
      6、 创建一个PDB    
cp init.ora  /u01/app/oracle/product/12.1.0/dbhome_1/dbs/initMACLEANCDB.ora

startup force;

CREATE PLUGGABLE DATABASE MACLEANCDB ADMIN USER MACadmin IDENTIFIED BY oracle
 FILE_NAME_CONVERT=(
  '/stage/oradata/MACLEANCDB/DC36ED41771D435CE0430100007FA00B/datafile/o1_mf_system_8rns0lxf_.dbf', '/stage/oradata/PDB1/datafile/system01.clone',
  '/stage/oradata/MACLEANCDB/DC36ED41771D435CE0430100007FA00B/datafile/o1_mf_sysaux_8rns13dk_.dbf', '/stage/oradata/PDB1/datafile/sysaux1.dbf.clone',
  '/stage/oradata/MACLEANCDB/DC36ED41771D435CE0430100007FA00B/datafile/o1_mf_temp_8rns1d89_.tmp', '/stage/oradata/PDB1/datafile/temp1.tmp.clone'
  )
 STORAGE UNLIMITED;
