CCI Environment Variables

Lists environment variables that relate to CCI.

Generic environment variables

CCITIMEOUT

Allows the specification, in tenths of seconds, of the maximum time out period that will be used with any LSC style application, such as Drag and Drop, SourceConnect, or the Monitor. The maximum value that can be used is 2,147,483,647.

Syntax

Windows:
SET CCITIMEOUT=value

UNIX:
CCITIMEOUT=value}
export CCITIMEOUT

Default

The default is 1200 (2 minutes).

Example

This example sets the value to 4 minutes:

SET CCITIMEOUT=2400

CCIERRLOG

Specifies the output location and filename of ccierr.log content which tracks first-instance errors reported from the operating systems. CCIERRLOG overrides any entries found in CCI.INI, where the syntax and content is explained in detail.

CCITRACE

Part of the process to enable CCI tracing is to specify the degree of information that will be traced, which can be done by setting the CCITRACE environment variable as follows:

Syntax

CCITRACE=filename [options]

Parameters

filename The name of the log file you want the trace output to go to. If you do not specify this parameter, the log file ccitrace.log is created in the current directory with all options set to their default states.
options Any, or all, of the following:

/F or -F	logs the details of CCI API calls to the trace file. The default is OFF, unless a `filename` any other trace option is specified, in which case it is always ON.
/P or -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 may be greatly increased.
/D or -D	logs the contents of all buffers passed to and from the CCI functions. The default is OFF. Data tracing may not be allowed if the application has been coded to prohibit data tracing for security reasons.

So to create a CCI trace file with the default name of ccitrc1.trc (with matching ccitrc1.idx file) which traces CCI API function flow, along with the underlying protocol function flow, but with no tracing of the user data passed to these calls, the value of the CCITRACE environment variable would be /P.

The CCI.INI file can also be used to control trace options, but any values specified by the CCITRACE environment variable will take precedence.

TCP/IP specific variables

CCITCP2

Instead of using the CCI Configuration Utility to set the TCP address of the machine running the CCITCP2 registration daemon the environment variable "CCITCP2" can be used instead. This may be useful if you need different processes on the same machine to contact different registration daemons.

Syntax

Windows:
set CCITCP2=hostname

UNIX:
CCITCP2=hostname
export CCITCP2

Parameters

hostname is the TCP hostname or dotted decimal IP address of the machine running the CCITCP2 daemon you wish to contact from that session.

Comments

The environment variable value will always take precedence over any value set using the Configuration Utility. To restore a process to using the value set by the Configuration Utility simply set the environment variable to an empty string, such as

set CCITCP2=

Alternatively, if this environment variable is set system-wide (by creating a system variable in the system environment settings, or by using a CONFIG.SYS file) then this value will always take precedence over any value set using the Configuration Utility.

CCITCP2_PORT

The port that is being used for the registration process.

Syntax

Windows:
set CCITCP2_PORT=port

UNIX:
CCITCP2_PORT=port
export CCITCP2_PORT

Parameters

port The port on which the CCITCP2 registration program operates.

Secure Connection (SSL) specific variables

RANDOM: If using SSL connections, externally generated random data that is stored as a numeric value in the RANDOM variable will be inserted into the initial salt value used to generate temporary key pairs used in SSL hand-shaking. The RANDOM value will only form part of the initial salt value and is an aid to generating more randomness and not an essential requirement.
COBSSL: If using SSL connections specifies the location of the DemoCA directory. If not found, SSLDIR is inspected instead.
SSLDIR: If using SSL connections, this value specifies the generic location of the system's OpenSSL directory.
