ASM instance debug işlemi

Oracle ASM instance’ında herşeyin normal olup olmadığını ara sıra kontrol etmekte fayda var. Bunun için bazı bilgileri toplayıp , asm instance’ının alert log dosyası incelenmelidir. Aşağıdaki betiği kullanarak gerekli bilgileri toplayabilirsiniz. Bu bilgiler doğrultusunda herşeyin yolunda olup olmadığını gözlemleyebilirsiniz.

Betiği , ASM instance’ına bağlanıp çalıştırmalısınız. Betik /tmp/asmdebug.our şeklinde bir çıktı üretecektir. Bu dosyanın yerini ve adını spool satırından değiştirebilirsiniz.

Aşağıdaki gibi ASM instance’ına bağlanıp,  betiği çalıştırabilirsiniz.
