MigratingOracle18cTo19c-candon123-51CTO博客

本文包含了以下两个知识点：

  1. 静默安装Oracle 19c；
  2. 通过rman升级数据库。

    一、静默安装Oracle 19c

    1.1 安装并配置Gird组件

    创建响应文件grid.rsp，内容如下：

    oracle.install.responseFileVersion=/oracle/install/rspfmt_crsinstall_response_schema_v19.0.0
INVENTORY_LOCATION=/u01/app/oraInventory
oracle.install.option=HA_CONFIG
ORACLE_BASE=/u01/app/grid
oracle.install.asm.OSDBA=asmdba
oracle.install.asm.OSOPER=asmoper
oracle.install.asm.OSASM=asmadmin
oracle.install.crs.config.scanType=LOCAL_SCAN
oracle.install.crs.config.SCANClientDataFile=
oracle.install.crs.config.gpnp.scanName=db-cluster-scan
oracle.install.crs.config.gpnp.scanPort=1521
oracle.install.crs.config.ClusterConfiguration=STANDALONE
oracle.install.crs.config.configureAsExtendedCluster=false
oracle.install.crs.config.memberClusterManifestFile=
oracle.install.crs.config.clusterName=db-cluster
oracle.install.crs.config.gpnp.configureGNS=false
oracle.install.crs.config.autoConfigureClusterNodeVIP=false
oracle.install.crs.config.gpnp.gnsOption=
oracle.install.crs.config.gpnp.gnsClientDataFile=
oracle.install.crs.config.gpnp.gnsSubDomain=
oracle.install.crs.config.gpnp.gnsVIPAddress=
oracle.install.crs.config.sites=
oracle.install.crs.config.clusterNodes=
oracle.install.crs.config.networkInterfaceList=
oracle.install.crs.configureGIMR=false
oracle.install.asm.configureGIMRDataDG=false
oracle.install.crs.config.storageOption=
oracle.install.crs.config.sharedFileSystemStorage.votingDiskLocations=
oracle.install.crs.config.sharedFileSystemStorage.ocrLocations=               
oracle.install.crs.config.useIPMI=false
oracle.install.crs.config.ipmi.bmcUsername=
oracle.install.crs.config.ipmi.bmcPassword=
oracle.install.asm.SYSASMPassword=abcABC12
oracle.install.asm.diskGroup.name=DATA
oracle.install.asm.diskGroup.redundancy=EXTERNAL
oracle.install.asm.diskGroup.AUSize=4
oracle.install.asm.diskGroup.FailureGroups=
oracle.install.asm.diskGroup.disksWithFailureGroupNames=/dev/sdb,
oracle.install.asm.diskGroup.disks=/dev/sdb
oracle.install.asm.diskGroup.quorumFailureGroupNames=
oracle.install.asm.diskGroup.diskDiscoveryString=/dev/sd*
oracle.install.asm.monitorPassword=abcABC12
oracle.install.asm.gimrDG.name=
oracle.install.asm.gimrDG.redundancy=
oracle.install.asm.gimrDG.AUSize=1
oracle.install.asm.gimrDG.FailureGroups=
oracle.install.asm.gimrDG.disksWithFailureGroupNames=
oracle.install.asm.gimrDG.disks=
oracle.install.asm.gimrDG.quorumFailureGroupNames=
oracle.install.asm.configureAFD=true
oracle.install.crs.configureRHPS=false
oracle.install.crs.config.ignoreDownNodes=false               
oracle.install.config.managementOption=NONE
oracle.install.config.omsHost=
oracle.install.config.omsPort=0
oracle.install.config.emAdminUser=
oracle.install.config.emAdminPassword=
oracle.install.crs.rootconfig.executeRootScript=true
oracle.install.crs.rootconfig.configMethod=ROOT
oracle.install.crs.rootconfig.sudoPath=
oracle.install.crs.rootconfig.sudoUserName=
oracle.install.crs.config.batchinfo=
oracle.install.crs.app.applicationAddress=
oracle.install.crs.deleteNode.nodes=

    如果使用AFD新特性，那么在安装之前，必须更改磁盘属主为grid用户，这里使用了两块磁盘：sdb和sdc，更改属主如下：

    [root@db03 ~]# chown grid:oinstall /dev/sd{b,c}

    使用下面的命令进行安装配置：

    [grid@db03 ~]$ cd $ORACLE_HOME
[grid@db03 grid]$ unzip /u02/software/19c/LINUX.x64_193000_grid_home.zip
[grid@db03 grid]$ ./gridSetup.sh  -silent -ignorePrereq -responseFile /tmp/grid.rsp

    响应文件里，默认只创建了一个data磁盘组，如果还需要创建其他的磁盘组，以FRA磁盘组为例，使用下面的命令：

    [grid@db03 grid]$ asmca -silent -createDiskGroup -diskGroupName FRA -diskList /dev/sdc -redundancy EXTERNAL -au_size 4 -sysAsmPassword abcABC12
--更改资源ora.driver.afd的组为oinstall，默认为asmadmin。
[grid@db03 ~]$ crsctl modify resource ora.driver.afd -attr "ACL='owner:grid:rwx,pgrp:oinstall:r-x,other::r--,user:grid:r-x' " -init
[grid@db03 ~]$ crsctl stat res ora.driver.afd -p|head -4

    1.2 安装database组件

    创建响应文件db.rsp，内容如下:

    oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v19.0.0
oracle.install.option=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/u01/app/oraInventory
ORACLE_BASE=/u01/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.OSDBA_GROUP=dba
oracle.install.db.OSOPER_GROUP=oper
oracle.install.db.OSBACKUPDBA_GROUP=dba
oracle.install.db.OSDGDBA_GROUP=dba
oracle.install.db.OSKMDBA_GROUP=dba
oracle.install.db.OSRACDBA_GROUP=dba
oracle.install.db.CLUSTER_NODES=
oracle.install.db.config.starterdb.type=GENERAL_PURPOSE
oracle.install.db.config.starterdb.globalDBName=
oracle.install.db.config.starterdb.SID=
oracle.install.db.ConfigureAsContainerDB=false
oracle.install.db.config.PDBName=
oracle.install.db.config.starterdb.characterSet=
oracle.install.db.config.starterdb.memoryOption=false
oracle.install.db.config.starterdb.memoryLimit=
oracle.install.db.config.starterdb.installExampleSchemas=false
oracle.install.db.config.starterdb.password.ALL=
oracle.install.db.config.starterdb.password.SYS=
oracle.install.db.config.starterdb.password.SYSTEM=
oracle.install.db.config.starterdb.password.DBSNMP=
oracle.install.db.config.starterdb.password.PDBADMIN=
oracle.install.db.config.starterdb.managementOption=DEFAULT
oracle.install.db.config.starterdb.omsHost=
oracle.install.db.config.starterdb.omsPort=0
oracle.install.db.config.starterdb.emAdminUser=
oracle.install.db.config.starterdb.emAdminPassword=
oracle.install.db.config.starterdb.enableRecovery=false
oracle.install.db.config.starterdb.storageType=
oracle.install.db.config.starterdb.fileSystemStorage.dataLocation=
oracle.install.db.config.starterdb.fileSystemStorage.recoveryLocation=
oracle.install.db.config.asm.diskGroup=
oracle.install.db.config.asm.ASMSNMPPassword=

    使用下面的命令开始安装：

    [oracle@db03 ~]$ cd $ORACLE_HOME
[oracle@db03 db_1]$ unzip /u02/software/19c/LINUX.x64_193000_db_home.zip
[oracle@db03 db_1]$ ./gridSetup.sh  -silent -ignorePrereq -responseFile /tmp/db.rsp
[root@db03 ~]# /u01/app/oracle/product/19.0.0/db_1/root.sh

    到此，整个19c的环境搭建完毕。

    二、迁移准备工作

    注意：新旧环境的数据库实例名必须保持一致。

    2.1 创建参数文件

    使用18c的spfile创建pfile，并复制到19c的目录。

    SQL> create pfile='/tmp/initcdb.ora' from spfile;
[oracle@db02 ~]$ scp /tmp/initcdb.ora db03:$ORACLE_HOME/dbs

    2.2 拷贝密码文件

    将18c的密码参数文件复制到19c的目录。

    [oracle@db02 ~]$ scp $ORACLE_HOME/dbs/orapwcdb db03:$ORACLE_HOME/dbs

    2.3 创建adump目录

    必须创建19c的adumo文件夹，否则使用pfile初次启动实例会报错。

    [oracle@db03 ~]$ mkdir -p /u01/app/oracle/admin/cdb/adump

    2.4 备份18c数据库

    [oracle@db02 ~]$ rman target /
run {
allocate channel c1 device type disk;
backup database format '/u02/orabak/rhndb_%U';
sql 'alter system archive log current';
backup format '/u02/orabak/%d_arch_%s_%p_%h' archivelog all delete all input;
backup format '/u02/orabak/controlfile_%d_%s_%p' current controlfile;
release channel c1;
}

    备份后的文件名如下图所示:
    Migrating Oracle 18c To 19c

    三、正式迁移过程

    整个过程就是一个异机恢复过程。只不过在恢复完成后，要以upgrade方式打开数据库，完成后续升级操作。

    3.1 恢复控制文件

[oracle@db03 ~]$ rman target /

RMAN> alter database mount;

released channel: ORA_DISK_1

3.2 创建spfile并注册资源

RMAN> create spfile='+data/cdb/spfilecdb.ora' from pfile;

Statement processed
[oracle@db03 ~]$ srvctl add database -db cdb -oraclehome /u01/app/oracle/product/19.0.0/db_1 -pwfile $ORACLE_HOME/dbs/orapwcdb -spfile '+DATA/CDB/spfilecdb.ora' -dbname cdb -diskgroup data,fra 
[oracle@db03 ~]$ echo 'SPFILE='+DATA/CDB/spfilecdb.ora'' >$ORACLE_HOME/dbs/initcdb.ora

3.3 恢复整个数据库

--在rman中运行如下命令进行全库恢复
run {
 allocate channel c1 device type disk;
 restore database;
 recover database;
 release channel c1;
 }

恢复完成后，以upgrade方式打开数据库并向temp表空间添加数据文件：

RMAN> alter database open resetlogs upgrade;
RMAN> alter tablespace temp add tempfile '+data' size 50M autoextend on next 100m maxsize unlimited;

3.4 执行dbupgrade进行升级操作

[oracle@db03 ~]$ dbupgrade -u sys

如果源库中存在多个pdb，那么这个升级过程会比较耗时。升级完成后，可以验证所有的组件以升级到19.0.0.0版本,如下图所示：
