Overview

APPS.INV_UTILITY_PVT is a private (PVT classification) PL/SQL package in Oracle EBS Inventory. It exposes a small set of low-level file-handling utilities used for debug logging rather than for any business transaction. The package header is declared AUTHID CURRENT_USER, meaning its procedures execute with the privileges of the invoking schema rather than the definer, and it is intended strictly for internal use by other inventory modules and Oracle development teams.

The package name and procedure signatures indicate a control-file pattern: callers first resolve a log directory, open a log file, write lines, and then close the file. Because the package is labeled private and references UTL_FILE and V$PARAMETER, its purpose is diagnostic tracing of concurrent or batch programs where output must be captured to an operating-system file.

Key Procedures and Functions

• GET_LOG_DIR — Returns the path name for the log directory as defined by the utl_file_dir initialization parameter. Because UTL_FILE can only write to directories listed in that parameter, this procedure resolves the effective directory value before any file is opened. It is a private procedure intended for internal consumers of the package.
• WRITE_DEBUG_FILE — Appends a message line to the currently opened log file. It accepts the line to write and performs the physical file output.
• OPEN_DEBUG_FILE — Opens the log file for writing, taking both the path name and the file name as inputs and returning standard status and message outputs.
• CLOSE_DEBUG_FILE — Closes the log file previously opened by OPEN_DEBUG_FILE, releasing the file handle.

All four procedures are documented as private. No public API surface is exposed, so they are not intended to be called directly by end-user extensions without acknowledgement that Oracle may change them without notice.

Tables Accessed

• UTL_FILE — Oracle's supplied PL/SQL file I/O package. It is used to open, write, and close the debug log on the database server file system. The package's procedures form a thin wrapper around this supplied utility.
• V$PARAMETER — The dynamic performance view over initialization parameters. It is referenced to read the utl_file_dir setting so that GET_LOG_DIR can return a directory path that UTL_FILE is permitted to use.

The metadata lists these two objects as referenced via APPS synonyms. No application tables are read or written, confirming that the package performs no persistent inventory data manipulation.

Usage Notes

This package is normally invoked indirectly. Typical callers are Inventory concurrent programs, batch interfaces, or other PL/SQL packages that need to emit trace output during processing. The standard sequence is: call GET_LOG_DIR to obtain the permitted directory, call OPEN_DEBUG_FILE with that path and a chosen file name, issue repeated WRITE_DEBUG_FILE calls as processing proceeds, and finally call CLOSE_DEBUG_FILE in the program's exception or cleanup block.

Because the package relies on utl_file_dir, the target directory must be included in the database initialization parameter, or file operations will fail. The parameter is read via V$PARAMETER, so the resolved value reflects the database instance setting at runtime rather than any hardcoded path.

Given that the package is classified as private and is referenced by zero other documented packages in the ETRM inventory, customizations should treat it as an unsupported internal utility. Debug logging should preferably be implemented through supported mechanisms, and any direct use of this package is at the implementer's own risk. The AUTHID CURRENT_USER declaration also means the invoking user must themselves hold the required privileges on UTL_FILE and the dynamic performance view. Refer to Oracle EBS 12.1.1 and 12.2.2 release-specific notes before relying on these procedures in a production extension.
