portal - Liferay configuration with many instances -


a question liferay configuration..

i have found it:

if want expose multiple websites different domain names same portal installation have create multiple portal instances. portal instance can created liferay control panel. data instances resides on same database. every table in liferay has column - companyid. each portal instance there unique companyid. id ued distinguish data multiple websites. can use sharding technique if want physically store data different instances different databases.

is possible create many liferay instances separate - data , users data (for login) shared in liferay instances?

if understand correctly saying want have users , data visible in companies or portal instances, eg:

  1. there 3 portal instances: c1, c2 & c3
  2. each instance has users: c1u1, c1u2, c2u1, c2u2, c2u3, c3u2 & on. these users able login respective instances only.

so want create few users u1, u2, u3 etc can login 3 liferay instances? shared between 3 liferay instances or independent of 3 instances?

in same sense want have blogs, wikis etc created visible users of 3 liferay instances?

solution
if above want, far know there no feature support sharing among portal instances. sharing data among sites have global scope, can't have shared users or data among portal instances.

all instances separated companyid, companyid present in database tables of liferay separate data among portal instances.

as per documentation portal instances:

data each portal instance kept separate every other portal instance. portal data, however, kept in same database.

so philosophy have data separate seems.
