本說明描述了在Linux OEL7上將兩節(jié)點(diǎn)Oracle 12c Release 2網(wǎng)格基礎(chǔ)設(shè)施環(huán)境升級(jí)到Oracle 19c的過程。

從12c升級(jí)到19c是以滾動(dòng)方式執(zhí)行的，使用批處理將限制應(yīng)用程序的停機(jī)時(shí)間。

為Oracle 19c網(wǎng)格基礎(chǔ)設(shè)施創(chuàng)建目錄結(jié)構(gòu)并解壓縮軟件。

[grid@rac01 bin]$ cd /u02/app

[grid@rac01 app]$ mkdir 19.3.0

[grid@rac01 app]$ cd 19.3.0/

[grid@rac01 19.3.0]$ mkdir grid

[grid@rac01 19.3.0]$ cd grid 

[grid@rac01 grid]$ unzip -q /media/sf_software/LINUX.X64_193000_grid_home.zip

安裝包kmod和kmod libs。

[root@rac01 etc]# yum install kmod
[root@rac01 etc]# yum install kmod-libs

使用群集驗(yàn)證實(shí)用程序（CVU）檢查當(dāng)前Oracle Clusterware的安裝是否準(zhǔn)備好升級(jí)。

從19c Grid Infrastructure主頁執(zhí)行：

./runcluvfy.sh stage -pre crsinst -upgrade -rolling -src_crshome /u01/app/12.2.0/grid -dest_crshome /u02/app/19.3.0/grid -dest_version 19.0.0.0.0 -fixup -verbose。

更新opatch版本并應(yīng)用補(bǔ)丁28553832和27006180。

[root@rac01 grid]# /u01/app/12.2.0/grid/OPatch/opatch version
