本文我们介绍一下升级暨迁移的其他技术
rman升级的主要步骤
1、在源库11.2，检查获取统计对象的并发收集设置
SQL> select dbms_stats.get_prefs('CONCURRENT') from dual;
DBMS_STATS.GET_PREFS('CONCURRENT')
--------------------------------------------------------------------------------
FALSE
SQL>如果并发收集设置部'FALSE'，进行如下设置
begin
dbms_stats.set_global_prefs('CONCURRENT','FALSE');
end;
/2、在源库执行dbupgdiag.sql收集诊断信息
cp dbupgdiag.sql $ORACLE_HOME/rdbms/admin
$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.4.0 Production
Copyright (c) 1982, 2013, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
With the Partitioning, Automatic Storage Management, OLAP, Data Mining
and Real Application Testing options
SQL> @?/rdbms/admin/dbupgdiag.sql
Enter value for 1: /tmp
SQL> @?/rdbms/admin/preupgrd.sql
Results of the checks are located at:
/u01/app/oracle/cfgtoollogs/CDBXF/preupgrade/preupgrade.log
Pre-Upgrade Fixup Script (run in source database environment):
/u01/app/oracle/cfgtoollogs/CDBXF/preupgrade/preupgrade_fixups.sql
Post-Upgrade Fixup Script (run shortly after upgrade):
/u01/app/oracle/cfgtoollogs/CDBXF/preupgrade/postupgrade_fixups.sql3、在源库11g执行rman备份，这里我们采用压缩备份方式
bakcup_cdbxf.sh
############################################################################
rman target / log=/rmanbak/cdbxf/cdbxf11gbak_20190629.log <<EOF
run {
ALLOCATE CHANNEL ch01 TYPE disk;
ALLOCATE CHANNEL ch02 TYPE disk;
ALLOCATE CHANNEL ch03 TYPE disk;
ALLOCATE CHANNEL ch04 TYPE disk;
backup as compressed backupset database format '/rmanbak/cdbxf/db_xf11g_full_%U' plus archivelog format '/rmanbak/cdbxf/db_xf11g_arch_%U';
backup current controlfile format '/rmanbak/cdbxf/db_xf_ctl_%U';
RELEASE CHANNEL ch01;
RELEASE CHANNEL ch02;
RELEASE CHANNEL ch03;
RELEASE CHANNEL ch04;
}
EOF############################################################################
4、将备份集传输到目标服务器上
由于我们采用异机升级方式所以需要将11g的rman备份集拷贝到12c的服务器上
$ scp db_xf11g_* oracle@ip:/rmanbak/cdbxf
The authenticity of host '' can't be established.
。。。。
Are you sure you want to continue connecting (yes/no)? yes
。。。。5、在12c数据库上创建密码文件
$ORACLE_HOME/bin/orapwd file=orapwCDBXFpassword=oracle
6、准备12c的参数文件
db_name=CDBXF12
*.compatible='12.1.0.0.0'
*.db_block_size=16384
*.db_file_name_convert='+data/cdbrxf','+data/cdbxf12'
*.log_file_name_convert='+data/cdbxf','+data/cdbxf12'
control_files='+data/cdbxf12/control01.ctl'
7、将辅助实例启动到nomount状态
$ echo $ORACLE_SID
CDBXF12
$ sqlplus / as sysdba
SQL*Plus: Release 12.1.0.1.0 Production on
Copyright (c) 1982, 2013, Oracle. All rights reserved.
Connected to an idle instance.
SYS@ CDBXF >startup nomount pfile='initCDBRXFora';
ORACLE instance started.
SYS@ CDBXF>8、 在rman下连接到AUXLIARY
$ export ORACLE_SID=CDBRXF
$ rman auxiliary /
Recovery Manager: Release
Copyright (c) 1982, 2013, Oracle and/or its affiliates. All rights reserved.
connected to auxiliary database: 12CXF (not mounted)
RMAN>9、使用12c rman执行duplicate
RMAN> connect auxiliary /
contents of Memory Script:
{
sql clone "create spfile from memory";
}
executing Memory Script
sql statement: create spfile from memory
contents of Memory Script:
{
shutdown clone immediate;
startup clone nomount;
}
executing Memory Script
。。。。
executing command: SET NEWNAME
executing command: SET NEWNAME
executing command: SET NEWNAME
executing command: SET NEWNAME
executing command: SET NEWNAME10、进行升级
SYS@ CDBXF >alter database open resetlogs upgrade;$ cd $ORACLE_HOME/rdbms/admin
$ pwd
