> " By default installation, all hosts start with their own Security database"
This is not really accurate - when you install MarkLogic - *very early on* in the installation process, before databases are created locally you are asked if you want to join a cluster. If you answer yes (by putting in a cluster host) then no local DB's are created, instead you become part of the cluster and share with it, its databases. Including security etc. http://docs.marklogic.com/guide/admin/hosts#id_39951 Databases not created then forgotten doing this. It is only the case where you do a fully independent install *then later* choose to join a cluster does the current installation "forget" about its databases. And that's not really accurate either because there's no real supported way (that I know of) to join a cluster later. You can force the situation behind-the-scenes but for "obvious reasons" it's not a good idea.

By default installation, all hosts start with their own Security database (, and Modules, and Schemas, and Triggers, and Apps, etc). But as soon as they join an existing cluster, they seem to forget they have forests, and databases of their own. The issue is of course that you cannot have two databases with the same name, so there is a logical explanation for why it currently is this way. But I am just wondering whether it is possible to make it slightly smarter.. I am only thinking about the Security database, just because it is such a vital database..

Unless you explicitly set it up differently, the Security database that all hosts have in a cluster is *the same database* (A single forest on the first host installed in the cluster).

It is pretty vital. Unless someone deliberately messed up, all hosts have a Security database. Couldn't it replicate that database across all other hosts by default, just like all other server configs are being shared automatically?

The default directory (/opt/MarkLogic/Forests on linux, for example) is known as a "private directory." For the procedure to move a forest to a public directory, see this section of the doc: http://docs.marklogic.com/guide/cluster/config-both-failover#id_57935 and this section: http://docs.marklogic.com/guide/cluster/config-both-failover#id_74893 Once you do that, you should be able to set up failover on that forest. -Danny ________________________________ From: [email protected]<mailto:[email protected]> [[email protected]] on behalf of Abhishek53 S [[email protected]] Sent: Monday, March 17, 2014 6:04 PM To: MarkLogic Developer Discussion Subject: [MarkLogic Dev General] Failed over Security Database Hi, I am trying rename and add forest-failover to the default "Security" database and getting exception Invalid input: Failover is not allowed for private forest: Security Please advise Abhishek Srivastav Tata Consultancy Services Mailto: [email protected]<mailto:[email protected]> Website: http://www.tcs.com ____________________________________________ Experience certainty.
