1. 檢查、準備必要的環(huán)境變量
# su - oracle
$ cat .bash_profile
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.2.0/dbhome_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:$PATH:$HOME/.local/bin:$HOME/bin
如果沒有以上環(huán)境變量需要加入魁袜。在命令行定義要創(chuàng)建的CDB數(shù)據(jù)庫的SID。
$ export ORACLE_SID=cdb1
2. 編輯pfile文件
必須增加的參數(shù)：
- db_name
- enable_pluggable_database
建議增加的參數(shù)：
- db_block_size
- control_files
可選的參數(shù)：
- db_create_file_dest 此參數(shù)的值是指定在創(chuàng)建數(shù)據(jù)庫時敦第，控制文件峰弹、redolog文件佛南、數(shù)據(jù)文件存儲路徑窃诉。如果使用ASM時芽腾，該值形如“+DATA”即可帽撑。
$ cd $ORACLE_HOME/dbs
$ cp init.ora initcdb1.ora
$ vim initcdb1.ora
$ cat initcdb1.ora
db_name='cdb1'
db_block_size=8192
control_files=(cdb1_control1, cdb1_control2, cdb1_control3)
enable_pluggable_database=TRUE
3. 編輯“創(chuàng)建數(shù)據(jù)庫”腳本
從Oracle官網(wǎng)，復制創(chuàng)建腳本蜘澜，并根據(jù)自己的定義進行修改宇立。
$ vim createcdb.sql
$ cat createcdb.sql
CREATE DATABASE cdb1
USER SYS IDENTIFIED BY Oracle123
USER SYSTEM IDENTIFIED BY Oracle123
LOGFILE GROUP 1 ('/oradata/cdb1/logdisk1/redo01a.log','/oradata/cdb1/logdisk2/redo01b.log')
SIZE 100M BLOCKSIZE 512,
GROUP 2 ('/oradata/cdb1/logdisk1/redo02a.log','/oradata/cdb1/logdisk2/redo02b.log')
SIZE 100M BLOCKSIZE 512,
GROUP 3 ('/oradata/cdb1/logdisk1/redo03a.log','/oradata/cdb1/logdisk2/redo03b.log')
SIZE 100M BLOCKSIZE 512
MAXLOGHISTORY 1

FILE_NAME_CONVERT = ('/oradata/cdb1/',
'/oradata/cdb1/pdbseed/')
SYSTEM DATAFILES SIZE 125M AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED
SYSAUX DATAFILES SIZE 100M
USER_DATA TABLESPACE usertbs
DATAFILE '/oradata/cdb1/pdbseed/usertbs01.dbf'
SIZE 200M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;
注意：路徑的創(chuàng)建垦缅。
$ mkdir -p /oradata/cdb1/{logdisk1,logdisk2,pdbseed}
如果參數(shù)文件中配置了DB_CREATE_FILE_DEST 參數(shù)舀射，可以使用下面的創(chuàng)建語句窘茁。
CREATE DATABASE cdb2
USER SYS IDENTIFIED BY Oracle123
USER SYSTEM IDENTIFIED BY Oracle123
CHARACTER SET AL32UTF8
NATIONAL CHARACTER SET AL16UTF16
EXTENT MANAGEMENT LOCAL
DEFAULT TABLESPACE users
DEFAULT TEMPORARY TABLESPACE temp
UNDO TABLESPACE undotbs1
ENABLE PLUGGABLE DATABASE
SEED
SYSTEM DATAFILES SIZE 125M AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED
SYSAUX DATAFILES SIZE 100M;
4. 執(zhí)行腳本創(chuàng)建CDB
