Check whether the client is connected to the server using the IPv6 or IPv4 protocol. You can also establish the connection by configuring the following parameters in the .ini file:
-Djava.net.preferIPv4Stack=true
-Djava.net.preferIPv6Stack=false
Table 2 lists the supported communication scenarios.
The first row and first column indicate the types of nodes that attempt to communicate with each other. x indicates that the nodes can communicate with each other.

Setting the Location for Creating Log Files
- Open the Data Studio.ini file.
- Provide the path for the -logfolder parameter.
For example:
-logfolder=c:\test1
In this case, the Data Studio.log file is created in the c:\test1\<user name>\logs path.
If any of the users does not have access to the path mentioned in the Data Studio.ini file, then Data Studio closes with the below pop-up message.
The Data Studio.log file will be created in the Data Studio\UserData\Username\logs path if:
- The path is not provided in the Data Studio.ini file.
For example: -logfolder=.
- The path provided does not exist.
Refer to the server manual for detailed information.
You can use any text editor to open and view the Data Studio.log file.
Controlling Exception and Error Logs
The stack running details of exception, error or throw-able are controlled based on the program argument parameter. This parameter is configured in the Data Studio.ini file.
-detailLogging=false
If the value of -detailLogging is set to True, errors, exceptions, or stack running details of throwables will be logged.
If the value of -detailLogging is set to False, errors, exceptions, or stack running details of throwables will not be logged.
Description of the Log Message
The log message is described as follows:
When the size of the Data Studio.log file reaches 10,000 KB (the maximum value), the system automatically creates a file and saves it as Data Studio.log.1. Logs in Data Studio.log are stored in Data Studio.log.1. When the size of the Data Studio.log file reaches the maximum again, the system will automatically create a file and save it as Data Studio.log.2. Latest logs are always written in the Data Studio.log file. This process continues till Data Studio.log.5 reaches the maximum file size and the cycle restarts. Data Studio deletes the earliest log file Data Studio.log.1. For example, the Data Studio.log.5 renames to Data Studio.log.4, the Data Studio.log.4 renames to Data Studio.log.3 and so on.
To enable performance logging in the server log file, the configuration parameter log_min_messages must be enabled and value must be set as debug1 in the configuration file data/postgresql.conf, that is, log_min_messages = debug1.
Different Types of Log Levels
The different types of log levels that are displayed in the Data Studio.log file are as follows:
- TRACE: The TRACE level provides more detailed information than the DEBUG level.
- DEBUG: The DEBUG level indicates the granular information events that are most useful for debugging an application.
- INFO: The INFO level indicates the information messages that highlight the progress of the application.
- WARN: The WARN level indicates potentially harmful situations.
- ERROR: The ERROR level indicates error events.
- FATAL: The FATAL level indicates event(s) which cause the application to abort.
- ALL: The ALL level turns on all the log levels.
- OFF: The OFF level turns off all the log levels. This is opposite to ALL level.
- If the user enters an invalid value to log level, then log level will be set to WARN.
- If the user does not provide any log level, then log level will be set to WARN.
The logger outputs all messages greater than or equal to its log level.
The order of the standard log4j levels is as follows:
|
- |
FATAL |
ERROR |
WARN |
INFO |
DEBUG |
TRACE |
|---|---|---|---|---|---|---|
