The following environment variables can be used for debugging CT-Library applications without the need to modify and relink:
SYBOCS_DEBUG_FLAGS–enables specific diagnostic subsystems. You can enable multiple debug options by specifying a comma-delimited list of flags in the variable.
SYBOCS_DEBUG_LOGFILE–specifies the log file where the diagnostics are recorded. If you do not set this variable, messages are written to stdout.
Debug flags that require devlib libraries still
require devlib libraries
even when using SYBOCS_DEBUG_LOGFILE.
For information about which ct_debug flag
parameters require devlib libraries,
see “ct_debug”.
To use these variables, set them before calling your CT-Library application. For example, on UNIX:
% setenv SYBOCS_DEBUG_FLAGS CS_DBG_SSL,CS_DBG_PROTOCOL
% setenv SYBOCS_DEBUG_LOGFILE libsybfssl.log
% ./isql –U sa –P –S my_ssl_server
% more libsybfssl.log
On Windows:
C:\> set SYBOCS_DEBUG_FLAGS=CS_DBG_SSL
C:\> set SYBOCS_DEBUG_LOGFILE=.\libsybfssl.log
C:\> isql –Usa –P –S my_ssl_server
C:\> type libsybfssl.log
