EMC SourceOne- 27 September 2012 - (0) Comments

Thomas Hampel
 27 September 2012

When running EMC SourceOne with Domino, it might happen that users can only see a subset of the mails they have received, even if the mail itself is stored in the EMC system.
Here are the details...


Problem
When logging in with Active Directory credentials, users can only see emails which have been sent to the internet address of that user.
Logging in with Notes/Domino user name and HTTPPassword, only the Lotus Notes mails can be found.

Analysis
By opening one email in each account and looking at the header, it became clear that EMC SourceOne can not associate the AD user name with the Notes user name.
The Notes user name is stored in a custom attribute of the Active Directory user object, but there is no option to customize the EMC software to make use of this attribute.

For each mail, EMC seems to use the recipients name as a string to search ActiveDirectory. So if the mail has been sent to "firstname.lastname@company.com" it will find a corresponding user in AD and can associate it with the user.
When the mail is sent to "Firstname Lastname/OU/O", there is no corresponding user in AD, at least not among the list of objects which EMC is searching in.

Those of you who have already migrated from Exchange to Domino already know that for perfect CoExistence between both systems, the AD user needs to have a Notes proxyAddress defined.
Based on this knowledge it was easy to resolve the problem.


Solution
adding the Notes user name to the list of email addresses ("proxyAddresses") in  the AD user object resolved the issue.

The result is another proxy address "NOTES:CN=Firstname Lastname/OU=X/O=Y" in addition to the internet address itself.

Domino Program documents and schedule- 6 September 2012 - (1) Comments

Thomas Hampel
 6 September 2012

Problem: A customer reported Domino would not be responding at a specific point in time, but servers dont crash - they are unresponsive.

Analysis
: Looking into the Domino server logs at about the time when the problem reported showed that some scheduled tasks were running.
While scrolling down the logs it became clear that the compact task was blocking access to the server's system databases - in this case log.nsf - which caused the server to ignore incomming requests.

From the end users point of view the server came to an halt while from the servers point of view all was okay.


Action:
Getting Domino program documents scheduled perfect could be a long journey. Here is my recommendation on how to do it right.
Program Command Line Schedule Comments
convert -l mailprimary.ind 18:50 each day
Repeat interval of: 0 minutes
Days of week: Sun, Mon, Tue, Wed, Thu, Fri, Sat
Generates a list of mail files by reading people's mail files from the Domino Directory and writes the list into an IND file.
compact -A mailprimary.ind 19:00 each day
Repeat interval of: 0 minutes
Days of week: Sun, Mon, Tue, Wed, Thu, Fri, Sat
Archive data but dont reduce the mail file size, thats because compacting will be done thru another program document.
compact -B -S 20 -w 23:00 each day
Repeat interval of: 0 minutes
Days of week: Fri
Once per week, reduce the file size if there are at least 20% whitespace in the file
Exclude system DB's with option -w , for servers before 8.5.4 this requires the variable DEBUG_ENABLE_COMPACT_8_5=1

Note: Reducing the file size for every file every day will just increase the level of fragmentation and will reduce performance.
compact -b -w 23:00 each day
Repeat interval of: 0 minutes
Days of week: Sun, Sat
Make sure the white space is located at the end of the NSF file for better performance when creating new documents
Note : Do not run on Friday, due to backup.
compact -b log.nsf 04:30 each day
Repeat interval of: 0 minutes
Days of week: Sun, Mon, Tue, Wed, Thu, Fri, Sat
Special schedule for log.nsf after 04:00 when purge has been completed.
To make sure the white space is located at the end of the NSF file for better performance when creating new documents.
catalog 01:00 each day
Repeat interval of: 0 minutes
Days of week: Sun, Mon, Tue, Wed, Thu, Fri, Sat
Updates information in catalog.nsf
updall 02:00 each day
Repeat interval of: 0 minutes
Days of week: Sun, Mon, Tue, Wed, Thu, Fri, Sat
Updates existing views
statlog 05:00 each day
Repeat interval of: 0 minutes
Days of week: Sun, Mon, Tue, Wed, Thu, Fri, Sat
Record statistics
daosmgr resync 23:30 each day
Repeat interval of: 0 minutes
Days of week: Mon, Wed, Fri
Every second day resync the DAOS repository
collect At server startup only Remark: Make sure the task is not loaded in the Notes.ini via “ServerTasks=”
http At server startup only Remark: Make sure the task is not loaded in the Notes.ini via “ServerTasks=”
rnrmgr At server startup only Remark: Make sure the task is not loaded in the Notes.ini via “ServerTasks=”
(n)server -c "tell sched validate" 02:00 each day
Repeat interval of: 0 minutes
Days of week: Sun, Mon, Tue, Wed, Thu, Fri, Sat
Rebuilds the clubusy/busytime
(n)server -c "tell mtc purge 7" 00:00 each day
Repeat interval of: 0 minutes
Days of week: Sun, Mon, Tue, Wed, Thu, Fri, Sat
Purge data older than 7 days from the message tracking store





Optional Program Documents for Specific Server Types
Program Command Line Schedule Comments
(n)server -c “tell router compact” 18:00 each day
Repeat interval of: 0 minutes
Days of week: Sun
This will reduce the file size of the mail.box'es, but will increase fragmentation on disk. Not recommended for servers with high mail volume.




Of course noone is perfect, so any comments and suggestions for improvements are very welcome !
