Oracle ASM trace file always starts with ‘+’, it is not working for below vi command to open and edit those kind of files:
$vi +ASM1_ora_20007.trc
or
$vi \+ASM1_ora_20007.trc
or
$vi *ASM1_ora_20007.trc
or
$vi "+ASM1_ora_20007.trc"
What we do is to open those kind of files by :
1) vi —
$ vi -- +ASM1_ora_20007.trc
OR
2) vi ./+ASM1_ora_20007.trc
$ vi ./+ASM1_ora_20007.trc
