In my database alert log I am seeing following error keep on generating periodically. Even though I have enough space in ASM I am not able to resize the datafile, add datafile etc.
The error is looks like some permission / space issue in ASM instance. When I checked the ASM alert.log file it shows like the database is not able to create some trace files to the file system. I cleared some space in the file system and which fixed the issue.
Below mentioned is the error which I got from the ASM alert.log file. Also check whether the ASM has sufficient permissions to write the files on the file system.
