The following database information is listed in the table on the main Advantage Database Server NLM screen.
Users/Connections: A "user" is defined as a single-client workstation that is connected to the Advantage Database Server. The number of users is not configurable because the maximum number of users is determined by the Advantage Database Server User Option purchased. Connections are defined as:
For Advantage DOS-based applications, a "connection" is defined as a single application connected to the Advantage Database Server.
For Advantage 16-bit Windows applications, a "connection" is defined as a single application connected to the Advantage Database Server. Additional "connections" to the Advantage Database Server via calls to the Advantage "connect" API can be obtained.
For Advantage 32-bit Windows applications, a "connection" is defined as a single application’s thread connected to the Advantage Database Server. Additional "connections" to the Advantage Database Server via calls to the Advantage "connect" API can be obtained.
Each "user" can have multiple active "connections". "Users" is not configurable, whereas "Connections" is configurable.
Work Areas Opened: A work area is a logical "container" that consists of a single open table, an optional memo file, and up to 15 index files.
Tables Opened: A table is an individual table within your database.
Index Files Opened: An index file is an individual file that can contain one or more index orders.
Data Locks: The data lock is a record lock, a table lock, an index file lock, a memo file lock, or a table header lock.
The Advantage Database Server NLM screen table includes a column for each database item. Definitions of the four columns are listed below.
Current: The current number of an item in use.
Max Used: The maximum number of resources actually in use at one time since the Advantage Database Server NLM was loaded.
Note The "Max Used" information is provided to help system administrators fine-tune the configuration of the Advantage Database Server NLM for optimal performance. For example, if after several days of active use, the maximum number of data locks in use at one time is 50, the system administrator could reconfigure the Advantage Database Server to allocate 55 data locks.
Configured: Shows the initial number of an item that the Advantage Database Server has available.
Rejected: Indicates that a configured value has been exceeded. If numbers frequently appear in this column, it is an indication that the Advantage Database Server NLM should be loaded with increased configuration parameters, or a larger User Option should be purchased.
Additional Advantage Database Server management information can be viewed from the Advantage Database Server NLM Screen. See Advantage Database Server NLM Management Utility for more information.
