Domino Limits

Domino Limits - Releases R5/6.x

For several years, Mike Woolsey maintained a list in the Business Partner Forum of the various known or guessed limits in Notes/Domino. He graciously agreed to allow this list to be distributed to any Lotus Customer, and I have decided to post it here and try to keep it up to date. If you see values which seem incorrect to you, post them as comments to my Limits in Notes/Domino blog entry and I'll update the information I have after I verify what I can. Feel free to link to this page or to the blog entry, and I'll make sure it stays around. There is a separate Domino Limits R4 page if you still need information on that. If you know of any errors in this list, let me know. Anyone knowing more limitations, please let me know (see blog entry above) and I'll update this doc. If I miss a limitation you mention elsewhere, let me know.



This is not documentation; it's what you can expect from R5/ND6 by way of limitations, if you don't know better. If you do know better, we'd like to! Some limits are still guesses or experienced but not proven. Known questionable entries have a question mark (?) beside them.

Domino Limits for R4


Domino Limits for ND6.5/ND7/ND8

Limits between ND6 and ND6.5 are generally identical, but since IBM support for ND6 has ended, I have grouped things this way.

LimitR5ND6
What is the maximum size of a database?64 GB (gigabyte) or the OS file system's limit (2 GB on some older UNIX platforms)

See note under ND6 about Macintosh limit of 2GB. Note sure if this is a problem for R5 or not
64 GB (gigabyte) or the OS file system's limit (2 GB on some older UNIX platforms). On Windows, the limit is OS file system limit, which for Windows 2003 is "way bigger than you'll ever need". It was previously reported that this could exceed 64 GB on Windows systems, but technote 1093509 states that this is not true, and readers have confirmed that 64 GB is a hard limit.

According to technote 1113005, there are some serious problems with >2GB size on Macintosh client.

How long can a remote-console command be, and still display properly in Administrator?77 characters. Some commands may handle more; others don't. The command itself is neither displayed nor logged as more than 77 characters.More than 77 characters (documented as "addressed" in K-Base, but no new maximum value is documented).
What is the maximum number of documents that can be selected when using the 'Archive Selected Documents' option?The limit appears to be 2047, according to this link.
Note Even though strings in LotusScript 4 (that's Notes and Domino 5) can be longer than 64K, there are still restrictions with the length of the string you can read or write using the GET and PUT statements. The only combination of filetypes that will work with long strings is with a binary file and a variable-length string. Fixed length strings, strings in variants, and random files will not work with strings greater than 64K in length because they have a two-byte header which contains the length of the string. Two bytes cannot represent more than 64K.
