Tracing and Debugging Environment Variables

This topic lists environment variables relate to the tracing and debugging functionality.

CCITRACE

You can specify the type of information that will be recorded by CCI tracing. To do this, configure the CCITRACE environment variable as follows:

CCITRACE=options

where any, or all, of the following options can be specified with a preceding / or -:

F

Logs the details of CCI API calls to the trace file. The default is OFF, unless any other trace option is specified, in which case it is ON.

P

Logs the details of protocol-level calls to the trace file. The default is OFF. If this flag is OFF, then only the details of the CCI user-level API will be traced. If this flag is ON, the level of function tracing might be greatly increased.

D

Logs the contents of all buffers passed to and from the CCI functions. The default is OFF.

Warning: This type of tracing might not produce the desired results if the application has been coded to prohibit data tracing.

The ctf.cfg and the CCI.INI file ([ccitrace_base] section) can also be used to control trace options, but any values specified by the CCITRACE environment variable will take precedence.

ES_DDBG_PORT_RANGE

A range of ports to use for dynamic debugging.

You specify a range of port numbers using either a hyphen or a comma.

If you use a hyphen, the values you specify are the start and the end of the port range, and the second port number must be greater than the first.

If you specify a comma, the values you specify are the start of the port range and the number of ports available from the start of the range.

Syntax

ES_DDBG_PORT_RANGE=value

Values

• low_port-high_port

  or

• low_port,number_of_ports

Default

If this is not set, dynamic debugging will use random ports.

Examples

The following definition specifies that ports 8001 through 8040 are to be used:

ES_DDBG_PORT_RANGE=8001-8040

The following definition specifies the same ports but using a different format:

ES_DDBG_PORT_RANGE=8001,40

Note: Micro Focus recommends that you use the Advanced Region Properties page in the Enterprise Server Common Web Administration (ESCWA) interface to configure this environment variable. See Advanced Region Properties for more information.

MFTRACE_ANNOTATIONS

The location of the trace files.

MFTRACE_CONFIG

The location of the CTF configuration file.

MFTRACE_LOGS

The location of the CTF log files.

MFTSO_DEBUG

Controls the display of debug messages.
