Windows Installer can use logging to help solve problems encountered during installation of software packages. Enable this logging by adding an entry and a value to the Registry. After you add and enable an item, you can retry the problematic installation. The Windows Installer tracks the installation progress and sends the progress to the temp folder. The new log file name is random, but starts with the le
When a DML error is found in a recent project, it takes about one minute to process more than one thousand pieces of data one by one from a temporary table insert to a formal table. The performance is quite low,
The DML error logging in Oracle 10 Gb has outstanding performance in handling DML exceptions. I originally intended to write an article about this feature. There is just a classic chapter.

introduction logging module is a python built-in standard module, mainly used for output log, you can set the level of output logs, log save path, log files and rollback, etc. It can be said that the logging module consists mainly of 4 parts: *logger Logger , which provides interfaces that application code can use directly NBSP;NBSP; *handler processor , sends log records generated by the logge

For Python, there are two problems that have plagued me these days:
There is no way to get the current line number and function name directly in 1.python. This is a question raised in the forum, and the bottom group is just guessing why Python does not offer __line__ and __func__ like __file__, but it does not find a solution at the end.
2. If a function does not know its name, how can it recursively invoke itself. This is a colleague of mine asked me, in fact, also get the function name, but it
When configuring the logging of the package, the gray "√" in front of the Containers,execute SQL task on the left indicates that the Execute SQL task inherits the configuration of the log records of the test log package.

Many programs have logging requirements, and the log contains information that has normal program access logs, there may be errors, warnings and other information output, Python's logging module provides a standard log interface, you can store various formats of the log, logging log can be divided into debug(),,, info() warning() and error() critical()5个级别, below
When writing code, it is often necessary to keep track of the process under which logging is used. The simple thing is that the print command prints to the terminal or writes to the file via the Open function. However, with the increase of the code volume, the drawback of the way is not controllable, also highlighted, which is the background of the logging module appears.For the
The example mainly solves the problem of changing the log storage location by passing in the log file parameters. If you need it, you can refer to the simple version of logging. config, which supports general configuration through the config file.
Another better way is to use the logging. config. fileConfig (log_config_file) method to read in and modify the handler method.
The Code is as follows:

1. Simply print the log to the screen
importlogginglogging.debug(‘This is debug message‘)logging.info(‘This is info message‘)logging.warning(‘This is warning message‘)屏幕上打印:WARNING:root:This is warning message
By default, logging prints the log to the screen with a log level of warning;Log level size relationships are: CRITICAL > ERROR > WARNING > INFO > DEBUG > NOTSET, and of course you can define the log level yourself.2.
In some cases, you can use the logging mode for the table and index segments, or the mode that does not log logs. If you are using a data pump to import a table segment or index segment, you can
Use the nologging mode, and use the data guard or a scenario that is high in availability to record the log, or even use the force log. This article describes how the index segment in the table segment is used

Objective
It is believed that every programmer should know that when using Python to write background tasks, it is often necessary to use an output log to record the state of the program running, and to save the details of the error in case of an error to debug and analyze. The Python logging module is a good helper in this case.
The logging module can specify the level of
