一、备库切主库升级

12c切换为19c主库的时候是由低版本到高版本所以cdb和pdb的数据字典需要进行升级才可以让数据与软件版本兼容。

1.1切换

SQL> alter database recover managed standby database finish;

Database altered.

SQL> alter database commit to switchover to primary;

Database altered.

1.2升级cdb

SQL>

 SQL> shu immediate

ORA-01109: database not open

Database dismounted.

ORACLE instance shut down.

SQL> startup upgrade;

ORACLE instance started.

1.4升级pdb1(19分51秒)

SQL> show pdbs

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED

---------- ------------------------------ ---------- ----------

         2 PDB$SEED                       READ ONLY  NO

         3 PDB1                           MOUNTED

SQL> alter pluggable database pdb1 open upgrade;

Pluggable database altered.

SQL> show pdbs

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED

---------- ------------------------------ ---------- ----------

         2 PDB$SEED                       READ ONLY  NO

         3 PDB1                           MIGRATE    YES

SQL>

注意:环境变量要配置好否则找不到数据库会瞬间完成脚本执行需要重新执行

[oracle@o12u19s ~]$ mkdir -p upDB

[oracle@o12u19s ~]$ $ORACLE_HOME/perl/bin/perl $ORACLE_HOME/rdbms/admin/catctl.pl -d $ORACLE_HOME/rdbms/admin -c 'PDB1' -l /home/oracle/upDB catupgrd.sql

重启数据库并进行编译

SQL> shu immediate

Database closed.

Database dismounted.

ORACLE instance shut down.

SQL> startup

ORACLE instance started.

重启后状态由

变为

1.5升级pdbseed(26分48秒)

$ORACLE_HOME/perl/bin/perl $ORACLE_HOME/rdbms/admin/catctl.pl -d $ORACLE_HOME/rdbms/admin -c 'PDB$SEED' -l /home/oracle/upDB catupgrd.sql

1.6编译失效对象

cd $ORACLE_HOME/rdbms/admin

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

[oracle@o12u19s ~]$ tail -f /u01/app/oracle/product/19.3.0.0/dbhome_1/rdbms/admin/utlrp*.log

1.7对pdb1temp表空间处理

SQL> show pdbs

    CON_ID CON_NAME                       OPEN MODE  RESTRICTED

---------- ------------------------------ ---------- ----------

         2 PDB$SEED                       READ ONLY  NO

         3 PDB1                           READ WRITE NO

SQL> alter session set container=pdb1;

Session altered.

SQL>

SQL> select tablespace_name,file_name,bytes/1024/1024file_size,autoextensible from dba_temp_files;

SQL> select status,enabled, name, bytes/1024/1024 file_size from v_$tempfile;

如果自动扩展为no需要开启自动扩展

alter database tempfile '/u01/app/oracle/oradata/orcldg/pdb1/temp012024-06-18_11-07-17-AM.dbf' autoextend on;
