UTL_FILE file handling capacity [message #234513]

Hi

We have some Pro*C programs which creates extracts from the database. We are planning to convert these into PL/SQL procedures. However, these files can be quite big at times. I wanted to know if there is any limitation in using UTL_FILE or any other packages on the size of the files. We are using Oracle 9.2.0.7 on HP-UX B.11.11

Thanks
SJC.

utl_file writes line per line, as does Pro*C, you have the same limitation.
Remember Pro*C program writes where it is executed (i.e. on the client), PL/SQL writes on the database server.

UTL_FILE is traditionally quite slow, but things change over time, so you need to benchmark it. utl_file in 9.2.x can be considered slow.
