Default Database Server Limitations
About this task
The default Database Server has the following limitations:
- The maximum per database is 2 Gigabytes.
- Performance begins to degrade after 5 connections.
Connections can include:
Procedure
-
Alarm Logging (
DLRP
). -
Point Logging (
PTDL
).When forwarding data (in store and forward), forward is a separate connection to the database.
- Alarm Logging forward connection.
-
Point Logging forward connection.
If the table is enabled for bulk insertion, bulk insertion requires a dedicated connection to the database in order to work. As a result, maintenance actions for bulk insert tables will need to allocate a separate connection. Once the action is completed, it will free the connection.
- Bulk insertion maintenance action.
-
Bulk insertion forward connection.
If there are too many tables enabled for bulk insertion there, resulting in too many connections at once, there will be a performance degrade.
If your system configuration regularly exceeds 5 connection, it is recommended that you upgrade to CIMPLICITY SQL, which is a more robust server.
