Ways that other tasks are affected by data sharing

Because data sharing does not change the application interface, application programmers and users have no new tasks. However, some programming, operational, and administrative tasks are unique to the data sharing environment.

The following tasks are unique to the data sharing environment:

• Establishing a naming convention for groups, group members, and resources
• Assigning new members to a data sharing group
• Merging catalog information when data from existing Db2 subsystems moves into a data sharing group

Because the Db2 catalog is shared, data definition, authorization, and control is the same as for non-data-sharing environments. An administrator needs to ensure that every object has a unique name, considering that existing data might be merged into a group. The data needs to reside on shared disks.
