Artikel ini menerangkan metode failover DNS. Dengan cara ini, sebuah server yang mati/tidak dapat diakses dapat digantikan oleh server backup dalam hitungan beberapa detik hingga 1 menit. Dalam artikel ini, www.example.com ingin dibuat menggunakan sistem failover DNS dengan dua server masing-masing server1.com (alamat IP 1.1.1.1) dan server2.com (alamat IP 2.2.2.2). Pertama, di nameserver example.com, set agar www.example.com menggunakan 2 NS yaitu server1 dan server2. ; zona EXAMPLE.COM WWW 60 IN NS server1.com. WWW 60 IN NS server2.com.

It calls C function system() to execute the command and returns always integer 0. These limitations make the UDF almost useless on recent MySQL server installations if the database administrator wants to get the exit status of the command as UDF output or the command standard output itself. I recently came across an open repository of MySQL User-Defined Functions … Read entire article »
