I use the UTLFILE function to write out debug log from within an oracle stored function I wish to ensure that two invocations of the same functions (multiple flowchart runs) try to change the contents of a file simultaneously Like this invocation 1 generates this debug line 1 invocation 2 of same function which happens in another client 251 UTLFILE. With the UTLFILE package, PLSQL programs can read and write operating system text files.
UTLFILE provides a restricted version of operating system stream file IO. This chapter contains the following topics: Using UTLFILE. Security Model. Operational Notes. Rules and Limits. Exceptions. Examples Oct 11, 2012 Using fopen funtion in code to open file as below: maxlinesize); Here max linesize, so as far as I think, limitation on database version?
It is most likely v7. 3. There is a bug whereby the append mode does not create the file. The workaround is to code: begin Files created using FOPEN are always writable and readable using the UTLFILE subprograms, INVALIDFILEHANDLE INVALIDOPERATION WRITEERROR FOPEN function.
This function opens a file. You can have a maximum of 50 files open simultaneously.

The utlfiledir setting is not a recomended setting for various reasons, and as suggested above, the CREATE DIRECTORY is the way to go (if On Oracle9i or later). How to write to files using utlfile in oracle. Ask Question. IF pinputROWCOUNT 0 THEN IF vExists THEN vFile: pFileName, pWriteMode); ELSE even if the append flag is passed if the file doesn't exist open it with W.
vFile: UTLFILE. FOPEN(pPath, pFileName, 'W'); END IF; GET On UNIX systems, the owner of a file created by the FOPEN function is the owner of the shadow process running the instance. Normally, this owner is ORACLE. Files created using FOPEN are always writable and readable using the UTLFILE subprograms, but non privileged users who need to read these files outside of PLSQL may need
