  6. Setup SLES for Domino using YaST • From a command prompt type yast • Install Required Packages • Go to -> Software -> Software Management • Make sure that you install the required packages for domino • You can also install other packages like mc and sysstat • Select Accept and OK • You can also use a command to install a package. Example: yast -i sysstat • Disable Postfix • Go to -> System -> System Services (Runlevel) • Select postfix, Disable and OK. Now the changes to the runlevels will be saved, select Yes • Select Quit to exit YaST

  7. Maximum number of file handles • Default maximum number of file handles for Domino is 1024 on Linux. If Domino is started from a login session edit the file /etc/security/limits.conf • Use WinSCP • Go to -> etc -> security and open limits.conf • Add: #Number of open files for notes notes soft nofile 49152 notes hard nofile 49152 #Number of processes/threads for notes notes soft nproc 12500 notes hard nproc 12500

  8. Domino Installation Guide • Login as root • Download Domino for Linux and Copy the .tar file to the server (Use WinSCP) • Untar the .tar file: tar –xvf nameofthetarfile.tar • Tar creates a sub-folder called linux in the folder we just unzipped in • Run the install script from linux/domino: ./install • Follow the instructions for the installation • Default user: notes • Default group: domino • Choose Remote Server Setup • When the Domino setup server is in listening mode use Remote Server Setup to finish the installation of the Domino Server

  9. Start/Stop Script by Daniel Nashed • For at få tilsendt Start-Script fra Daniel Nashed udfyld formularen på: http://www.nashcom.de/nshlstrq.nsf/StartScript!openform • Scriptet kan bruges til start/stop, monitorere og fejlsøgning (NSD)

  10. Start Script by Daniel Nashed • Copy the file rc_domino_script to the Domino binary directory (default /opt/ibm/lotus/ • Copy the file rc_domino to /etc/init.d/ • Ensure the script files are executable by root • chmod 755 /opt/ibm/lotus rc_domino_script • chmod 755 /etc/init.d/rc_domino • Check that regional settings are set to en_UK in /opt/ibm/lotus/rc_domino • Open /opt/ibm/lotus/rc_domino_script using WinSCP • DOMINO_LANG=en_UK • Add the script to INSSERV • insserv /etc/init.d/rc_domino • To verify that your service is correctly added to the rc-levels: find /etc/init.d/ -name “*domino*” which should give you something like this output: /etc/init.d/rc3.d/S11rc_domino /etc/init.d/rc3.d/K11rc_domino /etc/init.d/rc5.d/S11rc_domino /etc/init.d/rc5.d/K11rc_domino /etc/init.d/rc_domino

  11. Start Script Commands • /etc/ini t.d/rc_domino <command> • example: /etc/init.d/rc_domino start • start • starts the Domino server • start live • starts the Domino server and displays the live console • stop • stops the Domino server • stop live • stops the Domino server and displays the live console • restart • restarts the Domino server • restart live • restarts the Domino server and displays the live console • status • checks if the Domino server is running and prints a message • monitor • allows a kind of live console from a telnet/ssh session. ctrl+c or stop to terminate the live console

  12. Transactional Logging & View Rebuild • Enable Transactional Logging and change the path to /translogs • Set the path for View Rebuild to /view

  13. Notes.ini Settings • ClockType=24_Hour • set clock type to 24 hour format • DateOrder=DMY • set date order to Day Month Year • Update_Fulltext_Thread=1 • allows use of a separate thread to do Full Text Indexing so that long full text indexes don't delay View Updates • Updaters=2 • run 2 Update Tasks - as a rule of thumb do not exceed a maximum of one Update task per CPU • Replicators=2 • Will allow the server to replicate its databases with two servers simultaneously • Server_Session_Timeout=45 • will cause the Domino server to terminate a session that has been idle for the specified amount of time • Ftg_Use_Sys_Memory=1 • will instruct the full-text (FT) engine to directly use the operating system memory manager for large allocations, instead of requesting memory through the Notes Memory Manager and will avoid memory fragmentation

  14. Notes.ini Settings • Ft_Fly_Index_Off=1 • By default, when an agent that requires a full-text index runs against a database that does not have one, a temporary full-text index is created on the fly. This causes significant overhead for the server in direct proportion to the size of the index • Log_DisableTxnLogging=1 • The 'Log_DisableTXNLogging' setting will disable transaction logging for LOG.NSF. This will reduce resource demands on Domino • Create_R85_Log=1 • Beginning with Domino 8.5, the format of transaction logs can be optimized for Domino servers that use a block size different than the default block size of 512 bytesThe NOTES.INI option Create_R85_Log=1 will create new transaction logs with an updated format, properly aligning blocks for I/O • Create_R85_Databases=1 • enable ODS 51 as the default. Remember to run compact -c to change ODS

  15. Install Fix Pack • Shutdown the domino server  • Untar the .tar file: tar –xvf nameofthetarfile.tar • Tar creates a sub-folder called linux in the folder we just unzipped in • Run the install script from linux/domino: ./install • Follow the instructions for the installation • If you get the below error just make the terminal window size larger: Error: The minimum supported terminal size is 130 columns by 24 rows. Please ensure that the terminal/window used is at least this size.

  16. Linux Commands • ll - list information about the files in the current directory • cd - change the current working directory • pwd - print working directory • mv - move or rename a file • cp - copy a file • mkdir - creates a new directory • rm - remove a file • cat - list the content of a file • ifconfig - displays the status of the currently active interfaces • df - disk space available on all currently mounted file systems • du - disk usage of each file recursively for directories • mount - display all mounted filesystems

  17. Linux Commands (Performance) • top - display Linux tasks • ”top -u notes” - display only tasks for the user notes (domino tasks) • iostat - monitoring system input/output device loading • ”iostat -x 1” - monitoring disk performance • pmap - display process memory usage • ”pmap -d <pid>” - display memory usage for a specific process id • netstat - display network information • ”netstat -i” summarizes network activity

  18. Summarize • Install SLES • Add notes to domino group • Change owner on /tranlogs and /view • Edit limits.conf • Untar the .tar file and install Domino • Add start script
