Subject [jira] Commented: (DERBY-2182) Documentation for derby.system.bootAll is missing
Date Tue, 11 Dec 2007 00:44:43 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2182?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12550249
] 

Dag H. Wanvik commented on DERBY-2182:
--------------------------------------

Did some more research..

I find that if derby.system.home is explicitly set, autoboot will happen for databases located
in the directory
pointed to by that property (not if in subdirs tho).  Additionally, any databases pointed
to with one or more settings of derby.service.<dbdir>=serviceDirectory
are also booted at engine boot time.  In my first experiment I did not have derby.system.home
explicitly
set, hence my observation. I also checked the code to verify this.

derby.database.noAutoBoot  is a static database property. So it can be can be set with a call
to 

  syscs_util.syscs_set_database_property('derby.database.noAutoBoot', 'true');

If it set to true, that database will not boot, even if that database is otherwise determined
to be a candidate for autoboot according to the above rules.
So, it can be used to exclude some database(s) from the otherwise general rule of auto-booting
all databases found in derby.system.home and via the serviceDirectory method.

> This property is not documented in the Tuning Derby guide, but it is referred to 
> in the developer's guide in a couple of places with dangling pointers to the Tuning Guide:

> http://db.apache.org/derby/docs/dev/devguide/cdevcsecure60146.html

> Googling, I find it documented in older Cloudscape docs e.g. in
> http://www.novell.com/documentation/extendas37/docs/help/java/jdkee/cloudscape/doc/html/coredocs/proper42.htm#1014327,
> but not in Cloudscape 10 docs, e.g. http://publib.boulder.ibm.com/infocenter/cldscp10/topic/com.ibm.cloudscape.doc/perf63.htm
> which could indicate it was removed for some reason. So, either we
> should document it anew or remove the references to it. If we decide to keep it, we should
also consider
> derby.database.noAutoBoot (not currently documented).
