ORA-48913: Writing into trace file failed, file size limit [10485760] reached

ERROR:-
Non critical error ORA-48913 caught while writing to trace file
 "/apps/PROD/db/diag/rdbms/prod/PROD/trace/PROD_dbrm_6874.trc"
Error message: ORA-48913: Writing into trace file failed, file size limit [10485760] reached.


In some environments DBAs limit the size of trace files generated by the database. This included all trace files that could get generated under USER_DUMP_DEST/DIAGNOSTIC_DEST). The parameter to set the limit for trace files is MAX_DUMP_FILE_SIZE and its value is in OS number of blocks. After setting this value, if any trace file size would increase form the size specified in this parameter, ORA-48913 would be recorded in alert log file.

Cause
The reason was Parameter MAX_DUMP_FILE_SIZE  is set too low.

Solution
We can increase the setting for the parameter MAX_DUMP_FILE_SIZE or set it to unlimited
MAX_DUMP_FILE_SIZE specifies the maximum size of trace files (excluding the alert file). Change this limit if you are concerned that trace files may use too much space.
A numerical value for MAX_DUMP_FILE_SIZE specifies the maximum size in operating system blocks.
A number followed by a K or M suffix specifies the file size in kilobytes or megabytes.
The special value string UNLIMITED means that there is no upper limit on trace file size. Thus, dump files can be as large as the operating system permits.
