Transaction Log is a must have feature in Lotus Domino. If configured correctly, it’s almost speed up the whole Lotus Domino process. You can read more about Lotus Domino Transaction Log in here.
Transaction log need the fastest disk available, and also support failover. So, at least you need to have a dedicated raid 1 configured hard disk for transaction log files.
So, I follow the steps, using 2 x 15 k RPM SCSI hard disk and configure it as raid 1, and dedicated only for transaction log.
But, I still fell that the configuration is not fast enough, and I can’t get the faster hard disk, something is wrong.
After carefully studied, I found that to improve the hard disk performance of transaction log you need to use the non standard allocation unit size. The standard allocation unit size is 4092 bytes, don’t use it, manually change it to 32 kilobytes or even 64 kilobytes.
If somehow you already format the transaction log hard disk using the standard allocation unit size, to improve the transaction log performance, you need to re-format it with the new allocation unit size. There is third party software where you can change the allocation unit size without re-format, but you can do it with your own risk.
- Shut down the Lotus Domino server
- Backup all the transaction log files in ( no need special backup, just copy it into another disk).
- Format the disk, but do not use the standard allocation unit size (normally 4092 bytes), but change it into 32 kilobytes or 64 kilobytes. Do not use the quick format, use the slow format (just be safe)
- Restore the transaction log files.
- Start the Lotus Domino server
Now, your transaction log will work faster.
Last, do it in your own risk. It works in my Lotus Domino environment:
- Windows server 2003 x64,
- Lotus Domino 8.5.2 FP2 x64
And full backup will never hurt.

How to Safely Delete Lotus Domino Transaction Log File
Transaction Log is a must have feature in Lotus Domino. If configured correctly, it’s almost speed up the whole Lotus Domino process. You can read more about Lotus Domino Transaction Log in here.
If you enable the feature, and you should, than you need to have a proper backup system that support the transaction log. Without the proper backup system that support transaction log, the disk will filled up by the transaction log files. The backup system will backup the transaction log files and then delete them, thus will free up space in your hard disk.
But, what happen if the backup system somehow not backup thing properly? What happen if the backup system do not backup the transaction log files and do not delete them? What should we do?
Recently, I had the same problem. Somehow my backup software did not delete the transaction log file after backup. My raid 1 transaction log disk was almost full, and need to free up some space quickly, before it crashed.
The first rule is you should not delete the transaction log manually, it will crashed the Lotus Domino server, believe me, I tried.
This is the workaround.
You can disable the transaction log, restart the server, enable the transaction log again, and then restart the server again. The minus point is, after you re-enable the transaction log, the Lotus Domino will do some database fixup on all of your databases in the server, it may take hours or even days.
Or you can,
- Change the transaction log from archival style to circular style
- Restart the server. It will safely delete the old transaction log files, and than it will create around 4 GB of transaction log files.
- Change it again to archival style
- Restart again, it will delete the transaction log and than again re-create the transaction log files again.
With this method, you can safe the time for database fixup.
Last, always do it in your own risk. It works in my Lotus Domino environment:
- Windows server 2003 x64,
- Lotus Domino 8.5.2 FP2 x64
And full backup will never hurt.

What new in Lotus Notes 8.5.3
IBM just released lotus notes 8.5.3, available from IBM Passport Advantage website.
This is the new features of lotus notes 8.5.3
Lotus Notes 8.5.3 delivers significant enhancements to support social businesses and help users get their work done fast, for example:
- Lotus Notes and Domino 8.5.3 includes entitlement to the IBM Connections files and profiles components adding significant capabilities to help clients become a social business
- Enhanced new mail notification which optionally provides a pop up preview (containing both sender and subject) of new mail messages as they arrive.
- Improved sorting on email subject content that ignores the “Re:” and “Fw:” prefix, from reply & forward respectively, providing a more accurate sorting of your data.
- A new option to search by sender or subject available when you right click an email.
- Optionally leave countered meetings on your calendar. Allow countered meetings to show up in a unique color, with the time the meeting was originally scheduled for as well as maintaining the ability to act on the original calendar invite and with hover text indicating the new proposed time.
- Optionally notify existing invitees when adding or removing attendees from an existing meeting, informing them of the change and updating the invitee list on their calendar invitation, as well as other options which negate the need for a user to process any meeting updates for anything other than a change in time, eg. a reschedule.
- Significant improvements to recent contacts, allowing end users more control over who gets added to recent contacts and improved data integrity.
- Geographic and time zone information is be displayed in the business card.
- Apple Mac usability improvements for e-mail gestures include the ability to drag one or grouped files to the Lotus Notes icon on your dock, and a new mail message will be created with those files attached.
- Embedded IBM Sametime is upgraded to V8.5.1 with an incremental installer to IBM Sametime 8.5.2, and embedded IBM Lotus Symphony is upgraded to V3.0.
- Additional platform support includes RHEL 6.0 Desktop, Citrix XenApp 6.0, and enhanced 64-bit toleration for Microsoft Windows.
- Added ability to remove signature file from a thread
What is interesting is that is now lotus notes can sort the subject easily, without problem.
Prior this version, user have difficulties to sort emails based on their subject, because the “Re: ” and the “Fw: ” are treated differently. Outlook users do not have this kind of problem, but now lotus notes client too . Better late than never.
Hope that IBM much more open mind to user inputs than before.

How to speed up Lotus Notes client 8.5x
The first time I migrated MS Outlook to Lotus Notes, most users complain about the speed, and they said that MS Outlook is faster in any operations when compare to Lotus Notes.
I had to agreed with them.
I had to live with it, and thought that because it just they way it is, because Lotus Notes is not only an email client, but also a collaborations tool, that why it is slower compare to MS Outlook.
But I was wrong.
When I brought this up to IBM support, they came with a suggestion that I modified a file to increase the performance of Lotus Notes. And they were correct, with it Lotus Notes performance is a faster than before.
These are the steps:
- Close lotus notes.
- Open the folder/directory where you install lotus notes client, in my case c:\lotus\notes
- Find the file “\Lotus\Notes\framework\rcp\deploy\jvm.properties” and edit.
- Within the file, find the line “vmarg.Xmx=-Xmx256m” and change it into “vmarg.Xmx=-Xmx512m”
- Within the file, find the line “vmarg.Xms=-Xms48m” and change it into “vmarg.Xms=-Xms96m”
- Save the file.
Now, try to run Lotus Notes and see the differences. You can also play the setting, depend on your work load and your RAM. If you have more than 2 GB ram, you can try to increase the settings to:
vmarg.Xmx=-Xmx1024m
vmarg.Xms=-Xms256m
This improvement not only affects windows client, but also Linux or maybe Macs.
Please note that, if you apply the fix pack, the setting will be restores, so you need to re-edit it again.

This also come from IBM support
If you feel that you have a network problem while using Windows Vista or Windows 7, you can follow this suggestion.
Run this command (without the quotes) from command prompt from Windows vista or Windows 7, make sure you run it as administrator.
“netsh interface tcp set global autotuninglevel=disabled ”
This command will disable the windows network auto tunning, see here
And better to apply the latest fix pacth, the latest fix pacth as I’m writing this post for Lotus notes 8.5.2 is FP3.

About Lotus Domino Transaction Log
One of the feature of Lotus Domino that I can’t live without (as Lotus Domino administrator) is Transaction Log. Transaction Log help me a lot when the server crash (very rarely) and backup time.
Without the transaction log, when the server crash, it will take hours for the server to recovery. It will check every databases one at a time and try to check and fix if it found any problem. And when the database if being fix, the user can’t access it. If the database is big, more than 10 GB, it will take hours to complete it.
With transaction log, after the server crash, the server will ready in less than 15 minutes.
Without the transaction log, the backup procedure will become a problem. In my case the total databases size is more that 1 TB, and it will take almost 24 hours to complete the full backup. And it’s almost impossible to me to run full backup everyday.
With the transaction log, I only to run the full backup every week, and I only need to backup the transaction log for daily backup. Yes the full backup will take up to 24 hours for 1 TB data, for for daily backup, it take less than 1 hour backup.
So, if you have a medium size or large lotus domino server, I highly recommend that you to run it with transaction log enable.
Before that, these are a few tips.
- Use the fastest and dedicated hard drive that you can use for transaction log. I’m using IBM SAS drive with 15000 RPM, and that still too slow to me.
- Use raid 1 for transaction log, it recommended by IBM. So if one drive is failed, you still have one to run the transaction log.
- Backup, backup, backup. Transaction log rely on good backup that support transaction log, it will only clear up the old TXN files after the backup is complete. Without a good backup, your hard drive will filled up by the TXN files.
- If possible, use the latest Lotus Domino version. I have problem with Lotus Domino 8.5.2 FP1 that crash because the size of the transaction log, even the hard disk still have many free space. After consult with IBM support, they suggested me to upgrade the fixed pacth to FP2, after that the problem is gone.
