Effective June 1, 2020, OpenAccess 22.50 (DM5) will no longer be supported and no further source code changes will be made.
What this means for OpenAccess Coalition Members
The present OA 22.50 releases will be available for the near future, although members should consider plans to migrate to the new OpenAccess 22.60 (DM6). The migration plan is well designed as your OA 22.50 database still works in 22.60.
Should you choose to use the new data model features of OA 22.60 your database will become a DM6 database and can only be read with 22.60.
Going forward, the focus will be on the new OA22.60 data model. This includes support for C++ 11. New oaPartitions classes enable performance and portability enhancements to your applications, including parallel execution with partial loading of data.
The 4G limits have been relaxed on polygon point data and certain types of application defined data. In most cases, databases written by OA 22.60 will remain DM5/OA 22.50 compatible. OA 22.60 will only write a DM6 database if:
- more than 4G of oaAppProp or oaPointArray data is used or,
- oaPartitions are created
