2. PROBLEMATIC
Liferay Europe Symposium – Wiesbaden, Germany | 16-17 october 2012 2

3. Problematic
A classic data import/export use case
+ Transfer data between multiple environnements
•Need for
« Selective » export or import, not all data… Integration
Incremental import
• don’t push DB dump !
Q/A
+ Available tools
•« Site scope » data
LAR export / import
Remote stagging Acceptance
Resource Importer Plugin
•Data outside « site scope » (company-level data)
?... that’s the problem !
Production

6. Frontline feedback
Example : roles permissions definitions
+ Default permissions for roles
•A critical security configuration
2
1
3
+ How-to ?
•Without any tool (very painful) :
you need to write specific configuration procedure documentation (potentially huge)
You need to « replay » procedure manually (UI) for each environement (re-)initi
Unsafe (human error)
Build a tool to do the work (go back at home earlier !)
Fast to replay
Repeatable (error-prone)

7. Frontline feedback
Best practices to write import/export tools
+ Don’t work directly with database (SQL extract & load)
•Possible application-level data integrity violations
+ Only use portal services to read and write data
•Choose your weapon
Plain-old plugin, written in Java
Admin script, written in Groovy, Ruby, etc.
+ Be carreful about IDs
•An entity ID is not the same in source environment and target environment
Do not rely on entity ID
Relations between entities must not be stored with IDs
