Maximum number of databases on a single server

HCL Domino Domino Forum
1

Hi all,

For a customer of ours we use an archive domino server to archive old nsf’s on
It’s a simple server
windows 2012 server 64bits with 2GB ram
no tasks are started on the domino server.
no Agentmanager no compact or updall.

The Databases replicated to this machine are just sitting there.

Now we have the following problem.
There are 24.450 nsf’s on the server.
Every time i try to add another nsf it gives me the following error:

Notes error: Insufficient memory - NSF directory manager pool is full.

I tried
-rebooting the machine
-changing the notes.ini settings NSF_Buffer_Pool_Size_MB and DIRMAN_POOLSIZE_MB
-deleting the log.nsf and dbdirman.nsf (and recreating them)

any thoughts

Subject: DIRMAN_POOLSIZE_MB

What is DIRMAN_POOLSIZE_MB currently set too on the server?

Subject: ini settings

I removed all the settings

DIRMAN_POOLSIZE_MB
NSF_BUFFER_POOL_SIZE_MB
And NSF_Buffer_Pool_Size_MB

So my ini is clean. where to start?

Subject: Not aware of one.

I’m not aware of a database limit and you’d have to open a PMR for a definitive answer from IBM.

You could try increasing the 2GB of RAM to 8GB as it looks rather low.

There are some debug settings and instructions on how to run a manual NSD:

Subject: What about…

Have you tried increasing NSF_FOLDER_POOL_SIZE_MB

Subject: From what I can tell this is specifically related to the dbdirman pool

which has a min size of 24MB & a max size of 250MBs. You could try opening a pmr about the issue & we could give you a HF to allow a larger dbdirman pool.

Subject: DIRMAN_POOLSIZE_MB

John,

I tried different settings from 200 to 2048

Every time after changing i restart the Domino server (of course)

When none of these settings seemed to work i just removed the setting from the Notes.ini

Subject: DIRMAN_POOLSIZE_MB

I would leave this set to 250

What does the directory structure look like.

Subject: There’s another one: Is it possible NSF_BUFFER_POOL_SIZE is getting pinched?

First, is there a setting for NSF_BUFFER_POOL_SIZE_MB? If it were set long ago, it may well be set too low & need to be commented out.

Subject: NSF_FOLDER_POOL_SIZE_MB

D Porter,

NSF_FOLDER_POOL_SIZE_MB didn’t work for me.
I tried it with 100, 1024 and 2048.

Subject: Add memory debug…

Start with the debug entries in the notes.ini

CONSOLE_LOG_ENABLED=1
DEBUG_THREADID=1
DEBUG_SHOWLEAKS=1
DEBUG_TRAPLEAKS_SHOWSTACK=1
DEBUG_DUMP_FULL_HANDLE_TABLE=1
DEBUG_SHOW_MEMORY=1
DEBUG_TRAPLEAKS=826d

The DEBUG_TRAPLEAKS=826d entry is for the NSF directory manager and the DEBUG_THREADID=1 may show you what process is triggering the low memory event and you can go from there.

From the OS - you may want to run performance manager and monitor the disk queue length on the disk with the Domino data. If Domino is having to wait on the disk so it can process NSF files this could have an impact on long open handles on a large number of NSF files.

Subject: Is there

Is there a maximum of nsf files that can be stored on a single domino server?
