原文地址:rolling patch 作者:pluto_tt

   所谓的rolling patch,最大的特点在于,允许RAC环境下,不同实例运行在不同的数据库版本上,当然这个不同,指的是打上rolling patch后造成的版本不一致:

   比较让人容易误解的是,以为这是一种online patch,可以不用停数据库,在线打。

    rolling patch 还是需要停实例打的。比如在两个节点的RAC环境中,可以按这样的步骤操作:
    1、停实例1;

    2、打补丁;

    3、启实例1;

    4、停实例2;

    5、打补丁;

    6、启实例2。

   其中有一段时间,实例1、实例2同时启着,且数据库版本不一致,但数据库是不受影响,可以有效地减少停机时间。

如何查看patch是否为rolling patch:

1.在补丁目录:/etc/config下,有一个inventory文件,其中有一项:

              <online_rac_installable>trueonline_rac_installable>

若为true则为rolling patch

2.还可以使用opatch query命令:

Patch created on 18 Apr 2008, 02:57:01 hrs PST8PDT
Need to shutdown Oracle instances: true
Patch is roll-backable: true
Patch is a "Patchset Update": false
Patch is a rolling patch: true
Patch has sql related actions: false
Patch is an online patch: false
Patch is a portal patch: false
Patch is an "auto-enabled" patch: false

Patch is a rolling patch 一项true则为rolling patch。

昨天在测试环境上打了几个rolling patch,是加”local”选项,一个节点全打完,启动,再打另一个节点。
未加”local”选项时,则按提示起停实例即可,以下是网上搜到的一个打rolling patch日志,供大家参考(原链接已不能用,用Google快照打开的,不附出处了):
