Setting Up and Managing TELNETSYM
23.5 Managing and Customizing Your Print Queues
• TCPIP$TELNETSYM_SUPPRESS_FORMFEEDS
Suppresses form feeds between jobs. This includes the form feed that is
normally sent before the first job printed to a print queue and the form feed
sent at the end of every job. For more information, see Section 23.6.4.1.
23.5.2 Setting Up Error Logging
OPCOM messages sent by TELNETSYM include the name of the execution
queue. In addition, each TELNETSYM queue has a log file named
TCPIP$TELNETSYM_queue-name.LOG.
By default, TELNETSYM sends messages to the operator and records error and
informational messages in the file TCPIP$TELNETSYM_queue-name.LOG. This
file is located in SYS$SPECIFIC:[TCPIP$LPD].
You can use logical names to modify the way the TELNETSYM logs information
and the type of information it reports. For example, TELNETSYM can log
diagnostic messages that you can use when troubleshooting problems with a link.
Use the following logical names to modify error logging:
• TCPIP$TELNETSYM_VERBOSE
Turns on the logging of TELNETSYM diagnostics to the file
TCPIP$TELNETSYM.LOG. These diagnostics include informational messages
that indicate when links have come up or gone down and error messages.
• TCPIP$TELNETSYM_NO_OPCOM
Stops TELNETSYM from sending messages to the operator console.
• TCPIP$TELNETSYM_DEBUG
Used with TCPIP$TELNETSYM_VERBOSE, this logical name tells
TELNETSYM which diagnostic message types to log.
Specify a value for each bit. Each bit set in the value turns on a particular
logging function. The options are:
Bit 0 Tracks the flow of code. For example:
xyz-n-xyz-routine entered
Bit 1 Tracks the allocation of memory. For example:
just freed address 7F0000
Bit 2 Logs the bytes sent and received over TCP/IP link.
To set a bit, assign the value to the logical name whose binary equivalent
would have the bit set. For example, you can tell TELNETSYM to log
everything that it writes to and receives from the TCP/IP link by entering:
$ DEFINE /SYSTEM TCPIP$TELNETSYM_DEBUG 4
Decimal 4 is binary 100 with bit 2 set. Note that you can achieve different
combinations by setting more than one bit in the value. A value of 3, for
example, sets bits 0 and 1, causing logging of flow of code and memory
allocation diagnostics.
If TCPIP$TELNETSYM_DEBUG is undefined, TELNETSYM does not log
these diagnostics.
