ntDatabase

This example provides an EPICS V4 database that hosts EPICS V4 PVRecords. The records hold normative type pvData structures. The client program will connect to the database and then perform some demonstrations on how to interact with the records.

Building

If a proper RELEASE.local file exists two directory levels above ntDatabase, or in ntDatabase/configure/RELEASE.local then just type:

make

It can also be built by:

cp configure/ExampleRELEASE.local configure/RELEASE.local
edit file configure/RELEASE.local
make

To start the database as a standalone main

> pwd
/home/Epics/EPICS-CPP-4.5.0/ntDatabase/
> bin/$EPICS_HOST_ARCH/ntDatabaseMain

OR

> pwd
/home/Epics/EPICS-CPP-4.5.0/ntDatabase/
> serverRunner

To start the client program

> pwd
/home/Epics/EPICS-CPP-4.5.0/ntDatabase/
> bin/$EPICS_HOST_ARCH/ntDatabaseclient

OR

> pwd
/home/Epics/EPICS-CPP-4.5.0/ntDatabase/
> clientRunner
