Wondering if anyone has a solution to this configuration problem:
We are making various modifications to the DSpace 1.5 XMLUI, which requires
us to periodically test and release updated versions of software. We are
having trouble figuring out how to configure a pre-production staging
instance of DSpace. Normally, we would like to push all changes through a
series of instances:
DEV - private DEV tomcat instance, database and assetstore
QA - private QA tomcat instance, database and assetstore
STAGING - private STAGING tomcat instance, but using the
PUBLIC database and assetstore
PROD - public PROD tomcat instance, database and assetstore
The goal of STAGING is to test all code in a "production configuration",
e.g. with all production settings in dspace.cfg, before moving the changed
code to production with essentially a file copy.
We tried setting STAGING up with a local copy of the PROD assetstore, and
with the database as read only, and this failed to run. Apparently DSpace
needs to write to the database at startup. Is this true?
If DSpace must write to the database, then we may want to leave the
database as read/write. A followup question would be: is it safe to have
two instances of the DSpace tomcat webapp accessing the same database -
lets say so long as we do not submit any new items or modify items while
doing staging tests? Or will having two instances access the same database
cause the database to become corrupt?
Appreciate any thoughts someone more knowledgeable than I would have on the
viability of setting up this type of environment.
