Issue:

ORA-15028: ASM file not dropped; currently being accessed (DBD ERROR: OCIStmtExecute)

 Trying to drop a asm file which is actively used by ORACLE Database.

ASMCMD> rm -rf users01.dbf

ORA-15032: not all alterations performed

ORA-15028: ASM file '+DATA2/ORCL/users01.dbf' not dropped; currently being accessed (DBD ERROR: OCIStmtExecute)

Fix:

Take the file offline(or shut the DB down ) and then try again:

SQL> alter database datafile '+DATA2/orcl/users01.dbf' offline;

Database altered.

ASMCMD> rm -rf users01.dbf

ASMCMD> ls -l users01.dbf

ASMCMD-8002: entry 'users01.dbf' does not exist in directory '+DATA2/ORCL/'
