How to clear Navicat cache?

To extract specific data from backups, you must first clarify the backup format and structure, and then select the appropriate tools and methods. 1. Understand the backup format, such as iOS .backup, Android .ab or tar.gz, database .sql or .bak; 2. Use decompression tools such as 7-Zip, WinRAR or dd to process the image file. If encrypted, you need to decrypt the password or special tool; 3. Use iMazing, iExplorer or SQLiteBrowser and other tools to accurately extract contacts, text messages, photos and other data in iOS or Android; 4. The .ab file can be converted to tar through the command line and then decompressed to extract key content; 5. If there is no visualization tool, you can use SQL query or

The methods of running multiple tasks in a Windows batch script include: 1. Use the call command to call multiple .bat files to ensure that the previous one is executed before continuing; 2. Embed commands directly in a script and execute them in sequence, suitable for simple tasks; 3. Add start/wait parameters when calling external programs to wait for completion; 4. Error processing and process control are performed by checking %errorlevel%. These methods are applicable to different scenarios and can realize serial execution of tasks.

Navicat supports command-line automation tasks to improve efficiency. 1. Enable command line functions and configure environment variables during installation. The verification method is to enter navicat-version; 2. Use .ncx files to run predefined tasks, such as timed backup, and execute them through navicat-job command; 3. Directly execute simple tasks through command line parameters, such as exporting data, specifying operations with --export and other parameters; 4. Use scripting language to batch process multiple tasks, and use Shell or Python to loop to execute multiple .ncx files to achieve unified management.

Using Navicat to establish an SSL connection can improve database security. The steps are as follows: 1. Make sure that the database server has SSL support enabled, such as checking whether the have_ssl variable of MySQL is YES and confirming the certificate path; 2. Check "Use SSL" in the SSL tab of Navicat to upload CA files and client certificates (if required); 3. Check the certificate path and service status when the connection fails to be completed to avoid ignoring SSL verification in the production environment; 4. Use the latest version of Navicat to ensure compatibility. Secure connections can be achieved after correct configuration.

Common reasons for connection denied include not running the database service, firewall blocking ports, insufficient user permissions, and configuration errors. 1. Confirm that the database service has been started, Linux can use systemctlstatusmysql, and Windows can view it in the service manager; 2. Check whether the server firewall opens the corresponding port, such as 3306, and ensure that the cloud platform security group allows the port to communicate; 3. Configure the remote access permissions of database users, such as MySQL uses the GRANT command and check the bind-address settings; 4. Check whether the connection parameters of Navicat's host, port, protocol, etc. are correct. It is recommended to use command line tools to test the connection.

The method of checking database size varies according to the database type. The mainstream practices are as follows: 1. MySQL obtains the total database size by querying information_schema, or use graphical tools to view it; 2. PostgreSQL provides the pg_database_size and pg_size_pretty functions to display the size and formatted output of the specified database; 3. SQLServer uses the sp_spaceused stored procedure or view disk usage through SSMS; in addition, you need to pay attention to permissions, remote access restrictions and recommended to monitor the database growth trend regularly.
