Oracle VM 3.0.2 筆記

[Manager Discover Server Failed]

Oracle VM 3.0.2 並無法正確在VirtualBox中執行，VM Manager discover server時無法加入。

所以此狀況目前在虛擬環境無解。

若VM Server不是在虛擬機上，可以按照以下處理方式進行：來源

FIX ACTION: (ALL DONE AS ROOT, Do not remove any of your VM Servers from the manager)
1) Make sure the database is running (ps -aef | grep smon) you should see and entry with "ora_smon_"
2) Stopped OVMM. (/etc/init.d/ovmm stop)
3) cd /u01/app/oracle/ovm-manager-3/bin
4) sh ./ovm_upgrade.sh --dbuser=ovs --dbpass=[password for ovs] --deletedb --dbsid=[your SID]
5) cd /media/CDROM
6) ./runInstaller.sh
a) Choose Uninstall
b) Skip Uninstall of Java
c) Uninstall VM Manager 3.0
d) Uninstall Weblogic Server (you have to do this or the re-install will fail)
7) ./runInstaller.sh -u [INPUT YOUR EXISTING UUID]
(you can get this from your VM Server consoles or the .config file from list item 3 above)
8) Follow the prompts to re-install the VM Manager.
9) Discover your existing VM Servers, register your file Servers, discover your Repositories and so on.
10) You are done.

/etc/init.d/ovs-agent stop
rm -rf /etc/ovs-agent/db
/etc/init.d/ovs-agent start

筆記：取代^M

取代unix文件中的^M (http://zylix666.blogspot.com/2006/02/unixm.html)

^C的ascii碼\003

^M的ascii碼\015

cat file | tr -d "\015" > newfile

在vi中取代 (http://www.tech-recipes.com/unix_tips150.html)

Remove ^M characters at end of lines in vi

To remove the ^M characters at the end of all lines in vi, use:

:%s/^V^M//g

The ^v is a CONTROL-V character and ^m is a CONTROL-M. When you type this, it will look like this:

:%s/^M//g

In UNIX, you can escape a control character by preceeding it with a CONTROL-V. The :%s is a basic search and replace command in vi. It tells vi to replace the regular expression between the first and second slashes (^M) with the text between the second and third slashes (nothing in this case). The g at the end directs vi to search and replace globally (all occurrences).

筆記：Mac OSX 10.6.8 network printer problem

更新到Mac OSX 10.6.8之後列印公司Toshiba e-studio 255事務機會出現 /usr/libexec/cups/backenddnssd failed，有幸網路上有善心人事提供之前版本的檔案，剛剛將/usr/libexec/cups/backend路徑下dnssd, ipp, lpd三個檔案覆蓋回去後，終於可以列印了阿！

感謝神～

我沒有覆蓋socket是因為這個檔案內容看起來是針對HP使用，而我列印HP印表機很正常。

Reference

OS X 10.6.8 Update causes network printers to pause.

The files that need to be downgraded back to 10.6.6 or 10.6.7 are in the following folder.

/usr/libexec/cups/backend

The files to replace are as follows.

socket

dnssd

lpd

ipp

You need to backup these files first.

su: No directory!

check /etc/passwd /etc/shadow /etc/nsswitch.conf

User home directory permission

If settings is correct.

check / mount point permission.

Fatal Error

Solaris installation program exited.

You need to exclude NIS from the flarcreate:

flarcreate -S -c -n -I “servername-5.10-sun4v-date” -x /var/yp/binding/yourdomainname /var/tmp/servername-5.10-sun4v-date.flar

Or

flarcreate -S -c -n -I \
“`uname -n`-`uname -r`-`uname -m`-`date +%m%d%Y`” \
-x “/var/yp/binding/`domainname`” \
/var/tmp/”`uname -n`-`uname -r`-`uname -m`-`date +%m%d%Y`.flar”

Refrense: Error when trying to load a flar.
