### Basic oflog Configuration

Source: https://support.dcmtk.org/docs-snapshot/file_logger.html

This is a sample configuration file for oflog, demonstrating basic setup with log4cplus. It shows how to define loggers, appenders, and layouts for file logging. Lines starting with '#' are comments.

#  All rights reserved.  See COPYRIGHT file for details.
#
#  This software and supporting documentation were developed by

#    R&D Division Health
#    Escherweg 2
#    D-26121 Oldenburg, Germany
#
#
#  Module:  oflog
#
#  Author:  Uli Schlachter
#
#  Purpose: oflog sample configuration file
#

# This is an example config file for oflog. It's here to give an insight into
# some of the possibilities that oflog provides together with log4cplus.
#
# As you see, all lines that start with a '#' are comments.
#
# At any place in this file, you can use variables. They are expanded into
# settings from this file, e.g. ${log4cplus.rootLogger} would expand to the
# current value of this logger (see a few lines below). In addition, the
# following variables are predefined by oflog:
#
#  ${appname}        The name of the running application
#  ${date}, ${time}  The date and time at which this file was read
#  ${pid}            The process ID of the application which read this file
#  ${hostname}       The hostname of the machine on which we are running
#
# If no such setting exists, environment variables are tried. On most systems
# e.g. ${USER} would expand to the user name of the currently logged in user.
#
# Loggers are organized into hierarchies. If a log message is sent to the logger
# named dcmtk.dcmdata.libi2d, by default it will also be sent to dcmtk.dcmdata,
# dcmtk and the special "root logger" which is the base of the hierarchy.
#
# So, if you want to to catch all log messages, just configure the root logger:
log4cplus.rootLogger = DEBUG, console, logfile

# This line configures the root logger to sent all log events of level DEBUG or
# higher to the appenders "console" and "logfile" (see below).
#
# These are the available log levels, in ascending order:
# TRACE, DEBUG, INFO, WARN, ERROR, FATAL
#
# Now let's configure the above-mentioned appender called "console". Appenders
# take log events and send them somewhere. Since we want to see what's going on, 
# our console appender shows the message on the console (who would have
# thought). But since "debug" is a little verbose, we only display warnings and
# higher levels.
# You can use arbitrary names as the name for an appender.
log4cplus.appender.console = log4cplus::ConsoleAppender
log4cplus.appender.console.Threshold = INFO
log4cplus.appender.console.logToStderr = true
log4cplus.appender.console.ImmediateFlush = true

# As you can see, we are saying that console is of type "ConsoleAppender". Then
# we set some appender-specific properties. Each appender got different ones.

# Now let's configure the "logfile" appender which will write a logfile for us.
log4cplus.appender.logfile = log4cplus::FileAppender
log4cplus.appender.logfile.File = ${appname}.log
log4cplus.appender.logfile.Append = true
log4cplus.appender.logfile.ImmediateFlush = true

# One thing that all appenders need is a layout. It tells the appender how the
# log messages should be formated. The simple layout should be enough for
# starters, but the PatternLayout is way more flexible.
log4cplus.appender.console.layout = log4cplus::PatternLayout
log4cplus.appender.logfile.layout = log4cplus::PatternLayout

# The pattern layout can be told how the message should look like. Some of the
# available variables include:
# %n  A line ending
# %m  The actual log message
# %p  The log level of that message (TRACE, DEBUG, INFO, WARN, ERROR, FATAL)
# %P  The first character of the log level (T, D, I, W, E, F) - added to log4cplus
# %i  The process ID of the process generating the log entry
# %h  The hostname of the system generating the log entry
# %H  The full qualified domain name of the system generating the log entry
# %M  The function in which this log event was generated
# %F  The full filename of the source code file where this log event was generated
# %b  The basename of the source code file where this log event was generated
# %L  The line number where this log event was generated
# %l  This is equivalent to %F:%L
# %D{%m/%d/%y %H:%M:%S} The time when this log event was generated. %D is local
#     time, %d GMT. The available "time flags" are those from strftime() plus
#     %q and %Q (milliseconds and fractional milliseconds).
# A more complete list can be found here (if installed):
#     <htmldir>/classlog4cplus_1_1PatternLayout.html#_details
#
# The line below creates a PatternLayout which looks like a "standard"
# SimpleLayout, but which also includes the current time.
log4cplus.appender.console.layout.ConversionPattern = %D{%H:%M:%S} %5p: %m%n
log4cplus.appender.logfile.layout.ConversionPattern = %D{%Y-%m-%d %H:%M:%S.%q} %5p: %m%n

### DVInterface::startQueryRetrieveServer

Source: https://support.dcmtk.org/docs-snapshot/classDVInterface.html

Starts the query/retrieve server process (Query/Retrieve Service Class SCP). This process handles incoming DICOM associations, serves queries, and sends requested instances. Data is sourced from the local database. The configuration file is automatically created unless disabled. Note: A successful return does not guarantee the server has fully started, as some errors are only detected at runtime.

```APIDOC
## DVInterface::startQueryRetrieveServer

### Description
Starts the query/retrieve server process (Query/Retrieve Service Class SCP).

The query/retrieve process will wait for incoming DICOM associations, serve queries and send the requested instances to the specified destination. Data will be taken from the same local database used to store received instances and created presentation states, stored print objects and hardcopy grayscale images.

The configuration file which is required for the query/retrieve process will be created automatically from the 'global' configuration file each time this method is called, unless this automatical creation is disabled (entry: [QUERYRETIUEVE] AutoCreateConfigFile = false).

Attention: Successful return of this method is no guarantee that the query/retrieve server has successfully started, because certain errors (i.e. incorrect settings in the config file) will only be noted in the query/retrieve process when running. On Unix platform, successful return of this method means that the fork() used to start the receiver was successful. On Win32 platforms, it means that the CreateProcess() call was successful.

### Returns
EC_Normal if the query/retrieve process could be started, an error code otherwise.
