Installation of the managed PostgreSQL® with WinCC OA
As of version 3.20, PostgreSQL® is the default database. It is installed with the WinCC OA product installation - see also chapter Installation under Windows. When you create a new project,
NGA is automatically used with the PostgreSQL® database. This means that WinCC OA manages and installs the database.
CAUTION: If you want to use
PostgreSQL®, activate the PostgreSQL® Client checkbox of the installation wizard and install
the PostgreSQL client on all computers on which a PostgreSQL® backend is running
or "Direct Read" is used via PostgreSQL® backends. If you want to use
PostgreSQL® managed by WinCC OA, you must also install the
PostgreSQL® server on the computers on which the NGA Manager is running, by
ticking the PostgreSQL
server checkbox in the installation wizard.
Figure 1. PostgreSQL® Managed Installation
When creating a project, select PostgreSQL®
for the managed PostgreSQL® database - see chapter Archiving. If you are migrating to NGA, select the PostgreSQL® (managed)
option - see chapter Create new group.
Remote Installation
If you want to use a remote database instead of local database managed by emote-, then you must install the PostgreSQL® database
on the remote machine. For the installation of the client libraries on the WinCC OA server, see chapter PostgreSQL® Client Installation.
