Enable Transactional Logging by Default

[JoelProminic]

From @JustinProminic

Per this part of your e-mail:

Maintaining a Domino server with 12K+ databases presents significant challenges. For example, an unexpected shutdown causes Domino to run consistency checks on all databases during startup, which can extend the boot time from 1–2 minutes to over 10–15 minutes and complete the check spend some hours for 12k database, and in some cases even lead to another automatic shutdown. These scenarios have come up during my stress tests, and it's something we should be mindful of when scaling.

Please note we almost always have Domino Transactional Logging enabled. You should make this a default for your tests. In fact, it should already be a default for any Super.Human.Installer created instances of Domino.

Some documentation links:
https://help.hcl-software.com/domino/14.5.0/admin/othr_serverdocumenttransactionalloggingtab_t.html
https://help.hcl-software.com/domino/14.0.0/admin/admn_backupandrestorerequirements.html?scLang=en
https://help.hcl-software.com/domino/14.0.0/admin/upgrades_and_transactional_logging.html

Checking some servers that were recently created with the provisioners, it looks like Transactional logging is already enabled.

The fields are:

The values for TRANSLOG_Status, TRANSLOG_AutoFixup, and TRANSLOG_USEALL are:

Enabled|1
Disabled|0

The values for TRANSLOG_Style are:

Circular|0
Archived|1
Linear|2

The values for TRANSLOG_Performance are:

Favor runtime|1
Standard|2
Favor restart recovery time|3

I see the values are configured here:

hcl_roles/roles/domino_config/templates/setup.json.j2

Response from @JustinProminic

Thank you for the details.

The question remains then why is Bing not experiencing transaction logging?

Either the steps below are not working, or Bing is not using S.H.I. created instances of Domino.

Hi Mark,

Please INCREASE from 1024 for 4096 the value. Please check it with Doug. I think there was some bug at one point that the value had to be 4095 instead or something.
