System Status


Database server updated

The database server has been upgraded to macOS 10.12.4 from 10.11.6. In addition macOS Server has been upgraded to 5.3. The combined update has a number of security and performance enhancements (including plugging issues exploited by various intelligence agencies as exposed by Wikileaks.) 

MySQL and PostgreSQL database versions are at the latest revisions per this posting. 

All other grid servers are at the same versions as above. 

Grid on OpenSim 0.9 release candidate

The grid is now running the OpenSim 0.9 release candidate server version with a few additions that probably will find their way into the release version of 0.9. For now it runs with the Bullet physics engine, but tests with the ubODE engine has been promising, so we may see a switch later. There are some compatibility issues with scripts on ubODE that needs to be explored further. 

Updates deployed to grid servers

The grid servers have been updated to macOS 10.12.2 with a number of stability, performance and security fixes. In addition a number of fixes and improvements from the OpenSim 0.9.1 dev branch have been deployed. New functionality makes it possible to assign profiles to active NPCs that can be browsed in the viewer like an ordinary avatar profile.

PostgreSQL 9.6.1 and speedier connection

The main grid database have had another round of updates, this time moving PostgreSQL to version 9.6.1 which brings a number of bug fixes and updates.

The grid is again connected to a speedier connection. The initial line speed is 50/50 Mbit/sec, but the provider can go to bi-directional 1 Gb if needed. 

Formally the grid is still closed, but it is again possible to HG teleport to single regions.

Database upgrade to PostgreSQL 9.6

The grid database has successfully been upgraded from PostgreSQL version 9.4 to 9.6. This is a major upgrade with functionality for parallel queries, better replication technology for both scalability and failover, better text search with support for searching phrases in addition to “hybrid searches” combining relational, JSON, and full text searching

This comes in addition to improvements in version 9.5 with support of features such as UPSERT, row level security and support for much bigger data sets better indexing and faster sorts. 

UPSERT means the OpenSim code supporting PostgreSQL can be simplified. 

Grid is closed

XMIR grid is currently closed.

Grid servers updated

Grid and database servers have been updated with OS X 10.11.6 and OS X Server 5.1.7. These are primarily bug fix and performance improvements updates

Parcel attributes fixed

Parcel attributes are now working as they should, meaning that all media and audio settings you can configure via a viewer now both are set correctly and will persist over region restarts. 

The cause of the faulty behavior was missing code in the PostgreSQL database server adapter, so any change made in the viewer was never written to the grid database.

Other noteworthy changes is that objects will no longer be auto returned as long as someone is sitting on them. This is consistent with the behavior in SecondLife. 

A new OSSL scripting function; osGetPhysicsEngineName() as been added. This will return the physics engine and version the simulator for the region is running. 

Regressions for OpenSim 0.9 dev deployed to grid servers

A number of regressions for the OpenSim 0.9 development project has been deployed to all grid servers. These include areas such as group handling, region and parcel crossings, behavior of teleport hubs, and user preferences.

Bug fixes deployed to grid servers

A number of bug fixes have been deployed to the grid servers. 

This corrects an issue with sit target where avatar would hover about 10 cm over the item sat on. It also aligns sit behavior with SecondLife. 

In addition there are fixes for landmarks not being created in the Suitcase folder during a hypergrid visit, improvements to osRegionRestart, a fix to the asset server where object that are being deleted cannot be copied to a foreign asset server at the same time, and a check for HomeURI and GatekeeperURI back ported from arribasim. 

Finally parcel transfers now behave predictably where parcel title and description is updated in the viewers, and parcel sounds will play when crossing parcel borders.
