tputrace()
—User-defined trace information application.
#include <atmi.h>
int tputrace (char *trrec, int nest, char *category, char *funcname, int utrtype, va_list args)
tputrace(3c)
is a user-defined API the allows flexibility in monitoring and obtaining detailed trace output information (such as full user data content that is passed to or returned from ATMI functions) and defines how and where this information is output. By default, tputrace()
outputs trace record information to userlog(3c)
if the user does not update or modify otherwise.
tputrace(3c)
is called exclusively by specifying the utrace
receiver with TMTRACE
. For example: TMTRACE=atmi:utrace.
Specifying the utrace
receiver automatically invokes tputrace(3c)
and applies it only to atmi trace category records for output. For more TMTRACE
and utrace
receiver information, see tmtrace(5) in the File Formats, Data Descriptions, MIBs, and System Processes Reference.
Valid tputrace(3c)
arguments are:
Trace information record defined by user. ttrec
is always specified as the first argument in tputrace(3c)
. Outputting trrec
to the userlog, produces the same results as tmtrace(5).
Indicates whether tputrace(3c)
is called when entering or leaving an ATMI function. Set values as follows: 0
= entering, 1
= leaving.
Define arguments passed to the tputrace(3c)
output function. This includes user data or flags passed to ATMI functions. The list of the arguments for each ATMI functions are defined in the tputrace()
example implementation in the Example(s) section. The argument list is also available from tmtrace(5) trace information output.
A separate Tuxedo library, libutrace
, is used in conjunction with tputrace()
. The default libutrace
is installed in the Tuxedo system shared library directory ($TUXDIR/lib
in UNIX and %TUXDIR%\bin
in Windows).
Users can also write their own their own custom libutrace
library and can install it in either:
$APPDIR
in UNIX and %APPDIR%
in Windows).If the custom libutrace
library is installed in the system directory, it replaces the default libutrace
and is used by all Tuxedo clients and servers on the machine. If the custom libutrace
library is installed in the application directory, it is used only by the clients and the servers in the application.
Whenever tputrace()
is modified, the libutrace
library must be recompiled and linked to Tuxedo 9.0 or later. A sample tputrace()
source file is located in the $TUXDIR/samples/atmi/libutrace
directory.
The Example(s) section further illustrates how to customize tputrace()
.
Warning: The default or custom libutrace
library is loaded into every Tuxedo application process, including system servers such as BBL or WSL. This being the case, all Tuxedo system servers consume some amount of memory for loading libutrace
. The default libutrace
library is very small so memory consumption is negligible. But a custom libutrace can consume a larger amount of memory depending on how much functionality the user adds.
This is example shows the user-level trace information userlog output for the simpcl
execution of the Tuxedo simpapp
sample program.
In order to customize user-level trace information and output, you must do the following:

tmutrace(3c)
returns 0
when run successfully, and return -1
when a failure occurs.
Failure depends on the tputrace()
user-level implementation/customization. The default tputrace()
implementation included in Tuxedo 9.0 or later does not cause failure.
