做服装搭配图的网站危险网站怎么解除
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.
Total System Global Area 6174013840 bytes
Fixed Size 9148816 bytes
Variable Size 1056964608 bytes
Database Buffers 5100273664 bytes
Redo Buffers 7626752 bytes
Database mounted.
Database opened.

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

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;
1.8完成后检查升级问题及组件状态
