升级方案

升级PDB

如跨版本和跨平台迁移( 升级) ，可以使用OGG 升级迁移。

  拔插升级PDB

登陆主库，完成升级检查

# su - oracle

$ $ORACLE_HOME/jdk/bin/java -jar /u01/app/oracle/product/ 19.x.x/rdbms/admin/preupgrade.jar dir /tmp -c sjwpdb

运行修复脚本，并关闭PDB

$ sqlplus / as sysdba;

SQL> alter session set container=frankpdb;

SQL> @/tmp/preupgrade_fixups_frankpdb.sql

SQL> alter pluggable database frankpdb close immediate instances=all;

SQL> alter session set container=cdb$root;

SQL> alter pluggable database frankpdb unplug into '/backup/frankpdb.pdb';

SQL> drop pluggable database frankpdb keep datafiles;

拷贝frankpdb.pdb 去高版本数据库所在主机，打开数据库PDB

SQL> create pluggable database frankpdb using '/backup/frankpdb.pdb' FILE_NAME_CONVERT=('frankdb','franktest');

SQL> alter session set container=frankpdb;

SQL> alter pluggable database open upgrade;

升级PDB

$ $ORACLE_HOME/perl/bin/perl $ORACLE_HOME/rdbms/admin/catctl.pl -d $ORACLE_HOME/rdbms/admin -c 'frankpdb' -l $ORACLE_BASE catupgrd.sql

$ sqlplus / as sysdba;

SQL> alter pluggable database frankpdb open instances=all;

SQL> alter pluggable database frankpdb save state instances=all;

升级后校验和编译

$ cd $ORACLE_HOME/rdbms/admin/

$ $ORACLE_HOME/perl/bin/perl catcon.pl –c 'frankpdb' -n 1 -e -b postfixups -d '''.''' /tmp/cfgtoollogs/FRANKPDB/preupgrade/postupgrade_fixups.sql

$ $ORACLE_HOME/perl/bin/perl catcon.pl –c 'frankpdb' -n 1 -e -b comp -d '''.''' utlrp.sql
