ORA-27063: skgfospo: number of bytes read/written is incorrect

[marist89]

OK, here's your problem. You are allocating channels, but then specifying a single format. Try:

allocate channel c0 type disk format '/a03/app/oracle/admin/backup/bk0%U';
setlimit channel c0 kbytes 2097150;

allocate channel c1 type disk format '/a03/app/oracle/admin/backup/bk1%U';
setlimit channel c1 kbytes 2097150;

allocate channel c2 type disk format '/a03/app/oracle/admin/backup/bk2%U';
setlimit channel c2 kbytes 2097150;

allocate channel c3 type disk format '/a03/app/oracle/admin/backup/bk3%U';
setlimit channel c3 kbytes 2097150;


BACKUP
$BACKUP_TYPE
TAG hot_db_bk_level0
DATABASE;

release channel c0;
release channel c1;
release channel c2;
release channel c3;
