Data Sources
Data Sources
A data source is a logical grouping of MXOSRVRs. The data source definitions include
the basic configuration performed on the data source. MXCS requires data source
definitions on the NonStop server, and for ODBC clients on the client workstation.
Server Data Sources
Server data sources reside on a NonStop server. Each server data source represents
a pool of SQL MXCS servers that share the same NonStop SQL context. Use
NSM/web to add, remove, configure, and monitor server data sources. See Managing
MXCS Server Data Sources on page 3-3.
