MS Exchange database max GB

creating a DWORD registry key named “Database Size Limit in GB” in
- HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<servername>\Private-GUID
- HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<servername>\Public-GUID

MS exchange database

check the recyclable space:
- searching for event 1221 in the Application log. This is a conservative estimate and it seems only includes the EDB file only.
- ESEUTIL.EXE /MS <databases.edb>

check the recoverable items:
- use Performance Monitor with a specific counter called: “Total Size of Recoverable Items”.

defragment to copy to a new database (need to be offline and 110% of free space):
ESEUTIL.EXE /D <databases.edb>

tape backup -- tar, cpio

tar:
tar cvfM /dev/st0 sample //save; M for multivolume
tar tvf /dev/st0 //list
tar xvf /dev/st0 //restore
tar xvf /dev/st0 file //restore a file

cpio:
find . -depth -print | cpio -ov -C32768 > /dev/st0 //save
cpio -itv -C32768 < /dev/st0 //list
cpio -ivd -C32768< /dev/st0 //restore

find out file type on tape:
file - < /dev/st0

tape backup -- mt

mt -f /dev/st0 status //for status
mt -f /dev/st0 rewind // rewind the tape
mt -f /dev/st0 fsf1 // forward 1
mt -f /dev/st0 rewoffl // rewind and eject
mt -f /dev/st0 retension // forward and rewind
mt -f /dev/st0 erase // erase tape

mt exits with a status of 0 if the operation succeeded, 1 if the operation or device name given was invalid, or 2 if the operation failed.

find blocksize of tape:
dd if=/dev/st0 of=/tmp/dummy bs=128k count=1

SUSE 10 inetd becomes xinetd

Just found out that in SUSE 10, there is no inetd. It becomes xinetd.
I think we use YaST --> System --> Runlevel to control it.

rsync backup

My goal is to sync all backup files to a directory using rsync, rsyncd; and then for tape backup.

Method 1: using ssh rsync, it need to input password unless using ssh authentication (ssh-auth-keys).
e.g. rsync -avcrog --delete /source/ user@backupip:/backup

Method 2: using rsyncd, and rsync to push / pull the data from the rsyncd server. However, the rsyncd need to be running either by stand-alone daemon (rsync --daemon), inetd.
e.g. /etc/rsyncd.conf
uid = root
gid = root
[name]
hosts allow =
read only = true/false
write only = true
path = /path
auth users = user1,user2
secrets file = rsyncd.secrets

rsyncd.secrets / rsyncd.password
user:password
(old version need cr)

It seems it don't need to restart rsyncd after modify the rsyncd.conf to take effect.

MS Exchange User account Name change

After rename user from AD, the user can logon as the new username and using the old user profile. Nothing need to be changed/moved.
However, Outlook 2003 still showing the old name when the user send email.
I reset the AutoComplete Names from Outlook 2003 and sent the user an email using Addressbook and after that the new username show correctly...
I wonder if that is the real problem or actually the ADs are not in-sync...

OWL Intranet upgrade from 0.8x to 0.92

OWL Intranet upgrade is easy and it seems to work with php5.
Only need to replace the php files and run mysql script update, modify browser config and php.ini.
However, the ACL is totally different and I cannot find any scripts to do that.
need to add all files and folders to table advanced_acl with different rights accordingly to the security field on table files, folders. Also userid = 0 for everybody in the 0.9x
Also, php.ini need to change such as the following default values:
memory_limit = 8M
upload_max_filesize = 2M
Also, view.php need to comment the /lib/Mail_Mime/mimeDecode.php if pear is not installed for some file types. I wonder how to install some file types in pear
