aix433+sybase11<br /><br />好久没关机，那天正常光机，抱住它到另外一个柜子，重新开机，sybase就起不来了。<br /><br />exec(): 0509-036 Cannot load program /usr/sybase/bin/dataserver because of the following errors:<br />exec(): 0509-036 Cannot load program /usr/sybase/bin/dataserver because of the following errors:<br />        0509-130 Symbol resolution failed for /usr/lib/libc.a(aio.o) because:<br />        0509-136   Symbol       0509-130 Symbol resolution failed for /usr/lib/libc.a(aio.o) because:<br />        0509-136   Symbol kaio_rdwr (number 0) is not exported from<br />                   dependent module /unix.<br />        0509-136   Symbol listio (number 1) is not exported from<br />                   dependent module /unix.<br />        0509-136   Symbol acancel (number 2) is not exported from<br />                   dependent module /unix.<br />        0509-136   Symbol iosuspend (number 3) is not exported from<br />                   dependent module /unix.<br />        0509-136   Symbol aio_nwait (number 4) is not exported from<br />                   dependent module /unix.<br />kaio_rdwr (number 0) is not exported from<br />                   dependent module /unix.<br />        0509-136   Symbol listio (number 1) is not exported from<br />                   dependent module /unix.<br />        0509-136   Symbol acancel (number 2) is not exported from<br />                   dependent module /unix.<br />        0509-136   Symbol iosuspend (number 3) is not exported from<br />                   dependent module /unix.<br />        0509-136   Symbol aio_nwait (number 4) is not exported from<br />                   dependent module /unix.<br />        0509-192 Examine .loader section symbols with the<br />                 &#39;dump -Tv&#39; command.<br />        0509-192 Examine .loader section symbols with the<br />                 &#39;dump -Tv&#39; command.<br /><br />中间啥都没改过，backup server能起来。 不知哪出问题了。

你的数据库启动有没有一些限制？<br />比如必须在终端，不能在主控台之类？

应该没有，我就是在终端起的。<br /><br />另外，我发现aio0这个设备defind了。用cfgmgr也会出错。<br /><br />想把bos.rte.aio重装，但ML不对的话不知有没有问题。<br /><br />/usr/lib/methods/defaio: PdDv crit=&quot;class = &#39;aio&#39; AND subclass= &#39;node&#39; AND type = &#39;aio&#39;&quot; found no objects.<br />/usr/lib/methods/defaio: exiting with code 24<br /><br />Method error (/usr/lib/methods/defaio):<br />        0514-024 The specified predefined information does not exist<br />                 in the predefined device configuration database.<br />/usr/lib/methods/defaio: PdDv crit=&quot;class = &#39;aio&#39; AND subclass= &#39;node&#39; AND type = &#39;aio&#39;&quot; found no objects.<br />/usr/lib/methods/defaio: exiting with code 24<br />

没遇到过这种问题。<br />你确定你的数据库各种配置没修改过？<br />google到一篇http://www.chinaunix.net/jh/20/150352.html<br />不知道有没有帮助

还有这个：<br /><!--c1--><div class='codetop'>CODE</div><div class='codemain'><!--ec1--><br />Asynchronous I/O &#40;AIO&#41;<br /><br />Synchronous I/O occurs while the application waits. Asynchronous I/O runs in the background and does not block the application. The performance improves, because I/O operations and application processing can run simultaneously. Many I/O heavy applications, such databases and file servers, use this operation to overlap processing and I/O.<br /><br />Performance issue 1<br /><br />The benchmark used Oracle as the database subsystem. The Oracle database uses asynchronous I/O &#40;AIO&#41; as an I/O media to read and write data on the storage system. In AIX, by default, the AIO capability is off. There will be error messages generated by AIX when an application tries to use AIO while it is not enabled. The error message is not very clear. The following is a sample&#58; <br />0509-130 symbol resolution failed for /usr/lib/libc.a &#40;aio.o&#41; because<br />0509-136 symbol kaio_rdwr &#40;number 0&#41; is not exported from <br /> &nbsp; dependent module /unix<br /> <br /><br /><br /><br />Tuning <br />To enable AIO is simple. From &#34;smitty aio,&#34; <br /><br />Change / Show Characteristics of Asynchronous I/O <br />STATE to be configured at system restart <br />Choose &#34;available.&#34; <br />This change does not require a reboot.<br /><!--c2--></div><!--ec2-->

检查 /unix  这个link是否正确<br /><br />lrwxrwxrwx   1 root     system        21 May 01 2002  unix -&gt; /usr/lib/boot/unix<br />_mp<br />

link 是正确的，我用的是up，呵呵。<br /><br />现在正用beginner-bj的方法改odm的配置，企图修复aio。<br /><br />................................<br /><br />痛苦中，反过来想，sybase能否设置不用Asynchronous I/O？

好象是aio的问题，需要设置aio 为available

搞定了，请看我发的另外一个帖子，谢谢。<br /><br /><a href='http://www.loveunix.net/bbs/index.php?showtopic=48762' target='_blank'>http://www.loveunix.net/bbs/index.php?showtopic=48762</a>
