Multiple Database Connectivity

Hi,

Can we connect liferay with more than one database?

Is it possible to connect liferay with external database and as well as with liferay database too?

Regards,
Kavita

Liferay should use the liferay database for all of it's portlets and services.

You are free to connect to another database for any of your portlets and services, even when using ServiceBuilder.

Liferay supports database sharding as well as having different databases for read and writes.

Is it possible to connect liferay with external database and as well as with liferay database too?

Refer to "Liferay in Action" section "10.4 Accessing other databases.

Thanks for reply. I will look into Liferay in Action.

Hi there,

Yes is is possible. It all depends on your integration requirements, but the standard approach for integrating external data is to build your own service using service builder and configure it for using external db resource. I dont know if this is your case, but you should have a look at the SB section in documentation on Liferay.org.

Jan.
