Error messages with severity level 17 mean that the command has caused Adaptive Server to run out of resources or to exceed some limit set by the System Administrator. You can continue with the work you are doing, although you may not be able to execute a particular command.
These system limits include the number of databases that can be open at the same time and the number of connections allowed to Adaptive Server. They are stored in system tables and can be checked with sp_configure. See Chapter 4, “Setting Configuration Parameters,” for more information on changing configuration variables.
The Database Owner can correct the level 17 error messages indicating that you have run out of space. Other level 17 error messages should be corrected by the System Administrator.
