Answer 1

1. Basically nothing except phpMyAdmin is limited by PHP's timeout and resource limits (limits to keep a runaway script from bogging down your entire machine for all eternity; see the docs for details of those values. In some cases, you might be authenticating through a different user account (for instance, root@localhost and root@127.0.0.1 aren't the same user), but as long as you're using a user with the same permissions the differences are minimal.

2. You can read more about logs in the MySQL manual , note that "By default, no logs are enabled (except the error log on Windows)".

Answer 2

Below are answer for question

1. From my research the problem is that browser have some limit to disconnect the connection ie timeout connection. So that the above problem raised.

   To resolve this problem

   1. Go to /opt/lampp/phpmyadmin and open config.inc.php
   2. add the command $cfg['ExecTimeLimit'] = 0;
   3. Restart the xamp server. Now you can perform any operations.

` 2. Web client is differ from terminal because Terminal client will not getting timeout. Terminal client maintain the connection till the progress completed. I recommenced to use command prompt to import/export/run process by safe way.

1. Basically phpmyadmin will not have any log file. If you wanna see warnings and error you should configure the log file.

   Configuration steps:

   1. Go to /opt/lampp/etc/my.cnf
   2. Add log_bin = /opt/lampp/var/mysql/filename.log
   3. Restart the xamp server. You can get the log information.
