Logging SQL Server JDBC driver operations for Java application related cloud service

  • Artikel

To enable the logging of JDBC driver, please follow these steps -

1. Select your cloud service on Azure portal and open the Instances tab.

2. Select the instance and click on the connect button to initiate the remote desktop session.

 

3. You can use the existing logging.properties file from default location or you can create a new one and use it for logging.

 

Using the existing default logging.properties file -

1. Once you log in to your virtual machine, open the file explorer and traverse to JRE/lib in your environment.

2. You should find the logging.properties file. Just open it and edit it according to your logging needs. Sample properties file shown below.

 

Using your own logging.properties file -

1. Create a new logging.properties and place in the folder of your choice. Make sure the folder has required permission for access.

2. Add the JVM parameter "-Djava.util.logging.config.file=<drive>:<your folder path>/logging.properties" in your server configuration for launching.

 

After enabling these settings, you should see logs on console or a new log file is getting generated in your specified directory (default directory is your home directory. eg C:\Users\<your login name>\), depending on the handler that you enabled in the properties file.

 

Sample logging.properties file (Log file related settings are highlighted) -  

# The set of handlers to be loaded upon startup.

# Comma-separated list of class names.

handlers=java.util.logging.FileHandler, java.util.logging.ConsoleHandler

 

# Default global logging level.

# Loggers and Handlers may override this level

.level=ALL

 

# Loggers

# ------------------------------------------

# Loggers are usually attached to packages.

# Here, the level for each package is specified.

# The global level is used by default, so levels

# specified here simply act as an override.

# myapp.ui.level=ALL

 

# Handlers

# -----------------------------------------

# --- ConsoleHandler ---

# Override of global logging level

java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter

 

# --- FileHandler ---

# Override of global logging level

java.util.logging.FileHandler.level=ALL

 

# Naming style for the output file:

# (The output file is placed in the directory

# defined by the "user.home" System property.)

java.util.logging.FileHandler.pattern=%h/java%u.log

 

# Limiting size of output file in bytes:

java.util.logging.FileHandler.limit=50000

 

# Number of output files to cycle through, by appending an

# integer to the base file name:

java.util.logging.FileHandler.count=5

 

# Style of output (Simple or XML):

java.util.logging.FileHandler.formatter=java.util.logging.SimpleFormatter

    It's very straightforward to find out any topic on web as compared to textbooks, as I found this piece of writing at this web page.
