<p>如果你有很多TSM Server的可以安装：Integrated Solutions Console (ISC) and Administrative Center，类似IBM的HMC管理小型机，不太适合像我这样的字符控。AC6.2已经集成了ISC，不用再单独安装了，如下命令可以启动AC：</p>
<p>[root@TSMSRV bin]# cd /opt/ibm/ac/profiles/TIPProfile/bin</p>
<p>[root@TSMSRV bin]# ./startServer.sh server1 -username tipadmin -password tipadmin</p>

			<content:encoded><![CDATA[<p>昨天通宵恢复一个1T的数据库，早上6点成功恢复，立即开始备份。7点回家睡觉下午三点起床，也许这就是一个DBA的生活。本想现在写写恢复过程，不过又想睡觉了，明天好好写吧。</p>
<p>Updated  @ 2010-12-07</p>
<p><strong>一、系统背景：</strong><strong> </strong></p>
<p>硬件：    P690_1和P670_1</p>
<p>操作系统：A IX 5.2 ML04</p>
<p>数据库：  Oracle 9.2.0.1.0  2 Nodes RAC  HA</p>
<p>备库P570（非DG）： 与DG原理类似，利用生产库的归档日志在P570上恢复</p>
<p>故障时间：2010-11-23  13:20</p>
<p><strong>二、故障现象：</strong><strong> </strong></p>
<p>数据库系统在13：19报告SYSTEM表空间空间不够无法自动扩展，因为系统使用RAW设备所以无法自动扩展，需要管理员手工增加RAW设备文件。</p>

<p>时间：16：00</p>
<p>由于系统数据量大，在生产库不能短时间恢复情况下的</p>
<p>措施：启动P570备库</p>
<p>结果：启动备库P570失败</p>
<p>原因：在10月19增加数据库文件/dev/rphoto1026时出错，需要恢复。</p>
<p>时间：16：20</p>
<p>措施：利用生产系统RMAN备份来恢复</p>
<p>结果：无法恢复</p>
<p>原因：每晚8点的定时备份任务在14日由于备份空间不足备份失败，后续没有任务备份；系统归档日志保留策略为7天，若要恢复到14日备份前，缺少1天的归档日志文件。</p>
<p><span id="more-908"></span> 时间：16：30</p>
<p>措施：向公司上级汇报情况，商议决策</p>
<p>结果：与Oracle原厂工程取得系统，商议决策如下：</p>
<p>1.      保护好生产系统现状</p>
<p>2.      使用操作系统级dd命令备份生产系统所有数据文件</p>
<p>3.      将备份的文件用dd命令恢复到备库P570</p>
<p>4.      在备库P570上做恢复测试</p>
<p>时间：24日2：30</p>
<p>措施：在P570备机上重建control file，剔除/dev/rwwwdb_system04数据文件，尝试打开数据库。</p>
<p>结果：open失败</p>
<p>原因：Oracle 9i 系统表空间数据文件不能真正删除（10g开始可以）。</p>
<p>再次如下恢复操作：</p>
<p>重新创建/dev/rwwwdb_system04文件</p>
<p>SQL&gt; alter database create datafile &#8216;/dev/rwwwdb_system04&#8242; as &#8216;/dev/rwwwdb_system04&#8242;;</p>

<p>至此，生产系统数据库成功打开。</p>
<p>P670_1节点处理：</p>
<p>检查P670_1节点，发现主机访问DS4500存储系统上共享VG出现问题，为数据安全起见，先在P690_1节点备份数据库再处理P670_1节点。</p>
<p><strong>四、故障分析：</strong></p>
<p>在备份成功后，处理P670_1节点发现，DS4500存储系统B控制器坏掉，而引发了增加SYSTEM表空间失败。在更换存储系统控制器后，P670_1节点正常工作。</p>
<p><strong>五、改进与预防措施：</strong></p>
<p>1. 完善备份策略</p>
<p>2. 改善P570备库方式（采用rman备份归档日志，再恢复归档日志）</p>
<p>3. 每天检查生产系统的备份情况，及时发现问题及时处理。</p>
