How You Enable DAS Tracing

Because the DAS (iigcd) is a GCA-based server, it is a companion to the Ingres Name Server (iigcn) and the Communications Server (iigcc), and supports GCA tracing and other similar module tracing.

To enable DAS tracing, use either of these methods:

Add entries to the Ingres configuration file (config.dat) in the gcd section. This method is preferred because it allows trace output from multiple servers to be logged in the same file.
Set the environment variables prior to starting the server.

As a general rule, use the config.dat file for server tracing and the environment variables for client tracing.

The entries or values you must supply are as follows:

Configuration File Entry	Environment Variable	Value	Description
gcd_trace_log	II_GCD_LOG	log	Path and file name of the trace log
gcd_trace_level	II_GCD_TRACE	0 – 5	Tracing level for the DAS

Tracing Levels

The tracing level determines the type of information that is logged. The following levels are currently defined:

1 – Errors and exceptions

2 – High level method invocation

3 – High level method details

4 – Low level method invocation

5 – Low level method details
