GammaCompMD QA Client User Manual

3.2. Installation of the internal database

During the installation process, GammaCompMD QA also installs a PostgreSQL database, as

shown in Figure 10.

Figure 10: Database installation in progress…

This database is used to save all calibration actions, measurement data, QA tests and alerts

and to build a history of the status of the connected display over time.

In addition, the database is used for providing actual and historical data, when the Client

communicates with a GammaCompMD QA Server in a networked environment.

In case that a problem occurs during database installation or initialization, a message pops up

with an error code. Below find a small list of error codes and a short description related to

the installation/initialization of the GammaCompMD QA Client internal database during

installation.

Error Code

Description

Database connection error

Cancelled by another process

Database initialization error

Exceptional error in database

 GammaCompMD QA Client assumes that the user installing this application has full

(local) administration rights.

 The database communicates with the main application and with other system services via

IP address (127.0.0.1; localhost) and TCP port number: 5432.

To find the cause of an installation failure, please check (among other possible causes):

 Are there any limitations to the local administrator rights, or is an automatic creation of

an account blocked, i.e. via Microsoft’s advanced group policy management?

 Any TCP port conflicts with other applications, or any firewall port blocking?

 Does the system run another PostgreSQL or other database installation?
