What is the Chat Room tool?

Article

The Chat Room is a real-time, text-only chat tool within a site. The Chat Room tool can be used for synchronous, unstructured conversations among site participants who are logged into the site at the same time. Only participants enrolled in the same site may chat using the Chat Room.

The Chat Room tool supports multiple rooms and the default room can be set by the site owner. For example, instructors may choose to create an "Online Office Hours" chat room for student questions and answers. Chat rooms for student groups can also be set up as a space to collaborate among group members across distances.

The Chat Room tool alerts users to other participants who have entered the same chat room. This way, users know who is available to talk.

Site owners can specify how many chat messages are archived and for how long, or they can allow participants to configure their own archive settings.

The Chat Room tool does not provide a way to chat privately. By default, all messages are visible to all participants.

What is the admin Memory tool?

Article

The admin Memory tool allows administrators to view cache sizes in order to better optimize performance.

Sakai's default cache sizes and expiration settings are conservative and most likely need to be adjusted at large institutions.

All caches should be adjustable in Sakai 10.0+ with a simple modification to the sakai.properties file.

Adjust the caching of users especially if you use the JLDAP provider. This example will cache up to 50k users for up to half a day each:

• memory.org.sakaiproject.user.api.UserDirectoryService.callCache=timeToLiveSeconds=43400,timeToIdleSeconds=0,maxElementsInMemory=50000

Adjust the realm/role group cache to retain items in the cache for two hours:

• memory.org.sakaiproject.authz.impl.DbAuthzGroupService.realmRoleGroupCache=timeToLiveSeconds=7200,maxElementsInMemory=0

The user/site cache keeps track of the sites associated with the user:

• memory.org.sakaiproject.site.api.SiteService.userSiteCache=timeToLiveSeconds=86400,timeToIdleSeconds=0

The security service cache retains information about permission requests (e.g., can user xxxx do asn.submit in /site/abc):

• memory.org.sakaiproject.authz.api.SecurityService.cache=timeToLiveSeconds=86400,timeToIdleSeconds=0

How do I purge softly deleted sites?
