请教初始化库的一些问题，谢谢

突破瓶颈

现状：1、 在solaris上基于文件系统新装了一个informix数据库，库可以起起来 on_line 模式（自己测试学习用的）
      2、我需要逻辑日志已经物理日子从rootdbs中移出来，把系统从on_line模式转换到Quiescent模式，然后利用onspaces分配了一个逻辑日的dbspace以及大小
问题： 然后在用onspaces命令时长时间没反应，用onmode -ky也没反应。onmode -m也没反应。不知到哪里出问题了。自己也是刚学功底太薄，请xdjm多多帮忙 谢谢！

ps -ef | grep oninit
kill掉PPID为1的PID~~~

liaosnet

如果还不行~~~
ipcs
然后ipcrm 删掉informix在用的内存~~

liaosnet

如果还不行~~偶最后教你个绝的~~~












































reboot  your system!!

突破瓶颈

呵呵 o(∩_∩)o... 大师谢谢了 ，我用ipcrm删掉了共享内存，然后有初始化就好了，过程中还有许多不太明白，反正现在问题解决了。
不过新问题又出来了 哈哈 问题如下：  
1、要把逻辑日子从rootdbs中移出，是不是先删掉rootdbs中的逻辑日志，软后再在新建的llogdbs上指定逻辑日志？
   重新建立逻辑日志的时候，逻辑日志最少是3个我是不是要分别建立3次
2、我想把数据库的ontape -s 0 备份到本地硬盘 比如/opt/test 下面 这样我需要怎么做。

请大师帮忙呀

1,移逻辑日志的话,自己先在逻辑日志dbs上建几个新的逻辑日志~~然后移日志,做checkpoint,然后就可以删除在rootdbs上的逻辑日志...
相关操作onparms -a ;onmode -l ;onmode -c ;onparmas d ;ontape -s -L 0
2,备份到文件上~~~修改$ONCONFIG文件里的TAPEDEV~~~修改/opt/test 这个文件的属性为informix:informix 660..

大师 “~~然后移日志” 移日志怎么移

突破瓶颈

大师 好意思困惑还有好多

我想让备份做到 /opt/informix/test/informixbak 下 informixbak是我建的一个文件夹而且 “文件的属性为informix:informix 660”这些都做了
但运行 ontape -s -L 0  时 还是报下面的信息：
opt/informix/test> ;ontape -s -L 0

Please mount tape 1 on /opt/informix/test/informixbak and press Return to continue ...
could not write archive tape.
Please mount tape 1 on /opt/informix/test/informixbak and press Return to continue ...
could not write archive tape.


onconfig里面我已经改过来了如下：
# System Archive Tape Device

TAPEDEV         /opt/informix/test/informixbak # Tape device path      
TAPEBLK         16              # Tape block size (Kbytes)
TAPESIZE        10240           # Maximum amount of data to put on tape (Kbytes)

"informixbak是我建的一个文件夹"，确定是文件夹还是文件？应该是一个文件。

所谓移日志就是先在逻辑日志上新建日志,然后删除在rootdbs上的那几个....就是
onparams -a ;onparams -d;这两个操作~~
