oracleasmalias文件別名

今天在網上看到一個朋友問:為什麼在ASM存儲管理的方式下明明只設置了log_archive_dest_1來指定歸檔的路徑，卻在ASM下發現了兩處歸檔日志文件？（未開閃回）

我查了一些資料，認為是這樣的：
Every file created in ASM gets a system-generated filename, otherwise known as a fully qualified filename (FQFN). The fully qualified filename represents a complete path name in the ASM file system. An example of a fully qualified filename is:
