ORA-17502: ksfdcre:4 Failed to create file +DATA
ORA-15041: diskgroup space exhausted

failed to create file

This ORA-19504 error is related with the diskgroup space exhausted or Permission of the related directory.

You need to add disk to +DATA diskgroup to solve problem, or if you have chance to delete any files you should delete any files to allocate new spaces.

You can add disk to DATA diskgroup like below script.

ALTER DISKGROUP DATA ADD DISK '/dev/mapper/asmtsk1' NAME DATA_0002 SIZE 102399 M REBALANCE POWER 10;

[oracle@MehmetSalih]$ sqlplus / as sysasm

SQL*Plus: Release 12.1.0.2.0 Production on Thu Sep 27 11:02:46 2018

SQL>  ALTER DISKGROUP DATA ADD DISK '/dev/mapper/asmtsk1' NAME DATA_0002 SIZE 102399 M REBALANCE POWER 10;

You can add ASM disks using ASMCA tool, and you can read the following post to learn more details about Oracle ASM.

Or Sometimes You can try to add “%U” to all the formats starting with as follows.

RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   '/backup/bkp_df%t_s%s_s%p_%U';

RMAN> allocate channel c1 type disk format '/oracle/database/rman/backup/df_%d_%U_%p_%c';

Or other case’s solution is to Change the group of $ORACLE_HOME/bin/oracle (RDBMS_HOME) to asmadmin and also set the permission to 6751.
