ORA-19510: failed to set size of 475280 blocks for file "/flashrec_erpprd/ERPPRD/RMAN/bknpis04_1_1" (block size=512)
ORA-27041: unable to open file
Linux-x86_64 Error: 26: Text file busy
Additional information: 4
Tried to research it but could not find any relevant answers , my Db is 126.96.36.199
ls -l /flashrec_erpprd/ERPPRD/RMAN/bknpis04_1_1
ls -ld /flashrec_erpprd/ERPPRD/RMAN
ls -ld /flashrec_erpprd
Would change the destination of the RMAN backup and try again. Or would just try to backup "bknpis04_1_1" with new destination.
Something about "bknpis04_1_1" is not right. use v$datafile to check it.
"Text file busy" is a standard I/O error message for Error code 26. This error means that the program's unable to read/write from/to the file. Might be permissions. Might be conflict with the file ( lock) or something.
