Domino 8 Pre & Post Upgrade Tasks When Upgrading from 6.5 and 7.x

Mindwatering Incorporated
Tripp W Black on 01/14/2009 at 11:26 AM

Category: Domino Upgrades / Installations
Software Upgrade

Before Upgrading:
http://www-01.ibm.com/support/docview.wss?rs=475&uid=swg21303385
Run fixup, updall, and compact to verify applications' integrity.
Fixup -f -j -v -l
or
nfixup -f -j -v -l (MS Windows)

NOTE:
-f Exhaustive fixup, all documents are checked.
-j Include transaction logged databases. Without this option, fixup does not check logged databases.
-v Exclude database views (faster) for all views that will be rebuilt by updall later, no need to check view at this moment.
-l Log all processed databases (optional).

Updall -R -X
or
nupdall -R -X (MS Windows)

NOTE:
-R (Completely rebuilds the view indexes)
-X (Completely rebuilds the full text index, if the index exist)

Compact -c -i
or
ncompact -c -i (MS Windows)

NOTE:
-c Use copy-style compaction and recover unused white space
-i Ignore errors and allow compact to run anyway (only for copy-style)
If you are running transaction logging, be sure to use the -b switch. This is different than the upper case -B switch as -B will change the DBIID of any transactionally logged databases.

Update the notes.ini:
http://www-10.lotus.com/ldd/dominowiki.nsf/dx/database-ods-version-should-be-upgraded-to-the-latest-

Remove the following lines:
SERVER_SESSION_TIMEOUT
SERVER_MAXSESSIONS
SERVER_MAXUSERS

If you want your Domino 8 server to use the new ODS add the following:
CREATE_R8_DATABASES=1

If you want your Domino 8.5 server to use the new ODS add the following:
CREATE_R85_DATABASES=1
(remove the CREATE_R8_DATABASES=1 entry)

Upgrade the Server:

1. Upgrade an Admin Client
2. Upgrade your administrative server. (The one that is the administration server of the Domino - names.nsf.)
3. Do the immediate post upgrade tasks:
design -f names.nsf
design -f admin4.nsf
or
ndesign -f names.nsf
ndesign -f admin4.nsf

Note: the server will automatically rebuild the $Users and the $ServerAccess views. This can take quite a while on a large directory (15,000 users = approx 30 mins). You can do this off-line and then put your directory back into place right before you reboot it.
http://www.ibm.com/developerworks/lotus/documentation/releasenotes/?S_TACT=105AGX13&S_CMP=LPLOTUS

fixup names.nsf -f -j -v -l
fixup admin4.nsf -f -j -v -l
or
nfixup names.nsf -f -j -v -l
nfixup admin4.nsf -f -j -v -l

compact names.nsf -c -i
compact admin4.nsf -c -i
or
ncompact names.nsf -c -i
ncompact admin4.nsf -c -i

updall names.nsf -RX
updall admin4.nsf -RX
or
nupdall names.nsf -RX
nupdall admin4.nsf -RX

3. Replicate the directory.
Note: The 8.x design is safe back to 7.x and 8.x servers. Previous design servers should not be replicating the design. (We clicked the property to Update on Admin Server. We also don't have design task running nightly on the secondary servers.

Making Ubuntu 11.04 as Kiosk using Google Chrome

2011-05-07T10:19:00.004+09:00

1. Create Kiosk Users (with password)
2. Switch to Login Kiosk Users, Open Chrome to create default setting, Set Screensaver Setting (E.g. 5 minutes with no password lock)
3. Logout Kiosk Users, Switch back to your normal users
4. sudo vi /usr/share/xsessions/kiosk.desktop

[Desktop Entry]
Encoding=UTF-8
Name=Kiosk Mode
Comment=Chromium Kiosk Mode
Exec=/usr/share/xsessions/chromeKiosk.sh
Type=Application

5. sudo vi /usr/share/xsessions/chromeKiosk.sh

#!/bin/bash
while true; do google-chrome %u --incognito; sleep 5s; done

6. sudo chmod 755 /usr/share/xsessions/chromeKiosk.sh

7. sudo vi /home/kiosk/.dmrc

8. sudo chown root.root .dmrc

10. sudo vi /home/kiosk/.config/google-chrome/Default/Preferences

11. Change Kiosk Users to Auto Login without asking Password
12. Login Kiosk and Test

PS: Chrome will automatically reopen after 5 second, somehow if you want to logout that session, just kill chomeKiosk.sh in console will do.

Additional Comments

Installed using WineTricks VERSION=20091125 (IE7).
Downgraded to wine version to 1.1.31 to install jre-6u17-windows-i586.exe.
This is due to a regression in wine 1.1.32 - 1.1.34.
After install upgrade back to 1.1.34.
Added real XP Dll's to system32:
msctf.dll,msimtf.dll,oelpro32.dll,uxtheme.dll,xmllite.dll

Used winetricks to install:
comctl32,comctl32,corefonts,fontfix, gdiplus,msls31,msxml3-4 & 6,riched20 & 30,tahoma,allfonts

Used winecfg to set DLL Overrides:

"crypt32"="native,builtin"
"dispex"="native,builtin"
"gdiplus"="native"

Setup Syslog-ng Server for Cisco Device

2011-03-01T15:31:00.000+09:00

1. Install EPEL on CentOS
http://download.fedora.redhat.com/pub/epel/5/i386/repoview/epel-release.html
2. Yum install syslog-ng
3. vi /etc/syslog-ng/syslog-ng.conf
4. Remark default log settings (keep using syslog for system, syslog-ng for cisco device only)
5. Add

source s_sys {
   udp(ip(0.0.0.0) port(514));
};
filter f_router { facility(local3); };
###ROUTER IP###
filter f_A { host("1.1.1.1"); };
filter f_B { host("2.2.2.2"); };
filter f_C { host("3.3.3.3"); };
###UNKNOWN ROUTER###
filter f_unknown { not ( filter(f_A)
   or filter(f_B)
   or filter(f_C) ); };
###LOG FILE LOCATIOM###
destination A { file("/var/www/netlog/A.log" perm(0644) sync(10) ); };
destination B { file("/var/www/netlog/B.log" perm(0644) sync(20) ); };
destination C { file("/var/www/netlog/C.log" perm(0644) sync(20) ); };
destination unknown { file("/var/www/netlog/unknown.log" perm(0644) sync(10) ); };
###LOG SETTING###
log { source(s_sys); filter(f_router); filter(f_A); destination(A); };
log { source(s_sys); filter(f_router); filter(f_B); destination(B); };
log { source(s_sys); filter(f_router); filter(f_C); destination(C); };
log { source(s_sys); filter(f_router); filter(f_unknown); destination(unknown); };

6. Edit /etc/sysconfig/iptables and Add
-A RH-Firewall-1-INPUT -p udp -m udp --dport 514 -j ACCEPT
7. Edit /etc/httpd/conf.d/netlog.conf

Alias /netlog /var/www/netlog
<Location /netlog>
   Options Indexes Includes FollowSymLinks SymLinksifOwnerMatch MultiViews
   Order deny,allow
   Deny from all
   Allow from 163.50
   Allow from 172
   Allow from 192
</Location>

8. mkdir /var/www/netlog
9. service iptables restart & service syslog-ng restart & service httpd restart
10. chkconfig --level 3456 syslog-ng on
11. Edit /etc/logrotate.d/syslog-ng

/var/www/netlog/*.log {
   daily
   notifempty
   missingok
   copytruncate
   postrotate
   /sbin/service syslog-ng reload > /dev/null 2>/dev/null || true
   endscript
   compress
}

12. Configure your Cisco Router

Reclaim Disk Space using SVMotion

2011-02-21T12:38:00.000+09:00

1. Zero out disk space using sdelete or dd
2. Change Disk Format to Thick Provision by SVmotion
3. Power off PC, SVmotion the datastore with a different VMFS block size and change to Thin Provision.

Aligning VM Disk Partition

2011-02-20T11:31:00.001+09:00

Windows:
Very easy, boot Windows using Gparted, resize the partition with 1 MB free space before will be done.

Linux:
If you are not using LVM, simply do it using Gparted.
If you are using LVM (You can do it online, by move VolGroup from disk to disk!),
1. add a disk same size as the disk you want to align (E.g. the original disk /dev/sdb1 is 40G and belongs to VolGroup01)
2. using fdisk, create a new partition on /dev/sdc, moving beginning data to 128 (http://www.tcpdump.com/kb/virtualization/vmware-esx-server/vmware-disk-alignment/vmfs-liux.html)
3. pvcreate /dev/sdc1
4. vgextend VolGroup01 /dev/sdc1
5. pvmove /dev/sdb1 /dev/sdc1
6. vgreduce VolGroup01/dev/sdb1
7. pvremove ./dev/sdb1
8. shutdown your machine and remove your disk /dev/sdb1

REMARK: if you are using thin disk, this method will allocate whole disk size, you might want to shrink it be Storage Vmotion.
