LPS-97547 Remove legacy per portal instance properties configuration … https://liferay.dev/c/message_boards/find_thread?p_l_id=119785294&threadId=118247621 2026-06-12T14:46:36Z 2026-06-12T14:46:36Z Olaf Kock https://liferay.dev/c/message_boards/find_message?p_l_id=119785294&messageId=118278753 2020-01-15T10:05:05Z 2020-01-15T10:05:05Z

<div class="quote-title">jay kumar:</div><blockquote><br />Actually we wanted to store each customers data separate, also if we get new customer than we can design its separate lportal locally and then push it to production, binding instance with that lportal.<br /></blockquote><br />On top of what was written above: This is not how sharding <em>ever</em> worked. You could <em>never</em> arbitrarily bind different shards to different portals and move them around. A shard always belonged to a single portal. And it never was guaranteed to have the data of one instance exclusively and completely. In order to restore a portal from backup, you always needed all of the shards to be restored together.<br />Trust David and me: You don&#39;t want shards. If you want to strictly separate customers from each other, separating them in individual databases doesn&#39;t grant any security, as they&#39;re all accessed from the same JVM anyway. If you want to strictly separate them, run different servers.

Sorry, but sharding is gone. It cannot be done anymore. Well, some databases support sharding, but I would tread very careful here. It adds a lot of complexity, but what are the gains?<br />The question is: Why do you want sharding? Do you really need it?

Thank you so much Christoph Rabel , it is very helpful.<br /><br /><br />Can you please also guide me also on how to implement database sharding, as this feature is removed Now.<br /><br />How can we achieve this?

If you have your own module and configuration, it should be possible to set the scope to Scope.COMPANY. Then the configuration should appear in instance settings.<br /> <a href="https://portal.liferay.dev/docs/7-0/tutorials/-/knowledge_base/t/making-your-applications-configurable">https://portal.liferay.dev/docs/7-0/tutorials/-/knowledge_base/t/making-your-applications-configurable</a><br />e.g. like here:<br /><a href="https://github.com/liferay/liferay-portal/blob/7.2.x/modules/apps/product-navigation/product-navigation-personal-menu-api/src/main/java/com/liferay/product/navigation/personal/menu/configuration/PersonalMenuConfiguration.java">https://github.com/liferay/liferay-portal/blob/7.2.x/modules/apps/product-navigation/product-navigation-personal-menu-api/src/main/java/com/liferay/product/navigation/personal/menu/configuration/PersonalMenuConfiguration.java</a>

Server settings are global. You can&#39;t configure them per instance. I don&#39;t think it was ever possible to configure more than one mailserver.<br />You could try to override the mail implementation of Liferay but after a quick look I don&#39;t see a real nice way to do that. The MailEngine class which is used to send the mail is static and not &#34;OSGIyfied&#34;. Maybe you could try to replace MailMessageListener. <br />Another way would be to send mails to a local smtp server like postfix and dispatch them from there.

I also wanted to ask, i don&#39;t see Server Administration for each instance.I want to configure different SMTP settings for each one.<div class="quote-title">Christoph Rabel:</div><blockquote><br />A lot of configuration was moved to the frontend (System Settings and Instance Settings).<br />Can you tell us, which properties you are missing or what you try to achieve per instance?</blockquote>

I have connection settings for login. and during login.. each instance makes connection with its respective API for authenticating user.
