The goal of multitenancy is to maximize resource sharing by allowing multiple users (tenants) to log in and use a single server/cluster at the same time, in a tenant-isolated manner. That is, each user is given the experience of using his/her own server, rather than a shared environment. Multitenancy ensures optimal performance of the system's resources such as memory and hardware and also secures each tenant's personal data.
You can register tenant domains using the Management Console of WSO2 products.
When multitenancy is enabled and a tenant becomes inactive for a long period of time, the tenant is unloaded from the server's memory. By default, the time period is 30 minutes. After that, the tenant has to log in again before sending requests to the server.
You change the default time period allowed for tenant inactiveness by adding -Dtenant.idle.time=<time_in_minutes> java property to the product's startup script ( ./wso2server.sh file for Linux and wso2server.bat for Windows) as shown below:
JAVA_OPTS \
-Dtenant.idle.time=30 \
Adding a tenant
To add a new tenant, take the following steps:
- On the Configure tab of the management console, click Add New Tenant.
- Enter the information about this tenant as follows:
- Domain - The domain name for the organization, which should be a unique name (e.g., abc.com)
- Usage plan for the tenant - The usage plan defines limitations (such as number of users) for the tenant.
- First Name - First name of the tenant admin.
- Last Name - Last name of the tenant admin.
- Admin Username - The username the tenant admin will use to log in. The username must always end with the domain name (e.g., admin@abc.com).
- Email - The email address of the admin.
Viewing tenants
To view existing tenants, on the Configure tab in the Identity Server Management Console, click View Tenants.
