The HFS Unload Utility

In the OS/390 UNIX environment, the Hierarchical File System (HFS) contains files and directories. The security information for these files and directories resides within the file system itself, not within the RACF database. Thus, the RACF Database Unload Utility (IRRDBU00) cannot be used to report on HFS security data.

The irrhfsu utility will report on the HFS security data in a manner consistent with IRRDBU00. For each file and directory in the currently mounted file system structure, a record will be created which contains security data: permissions bits, owner, audit settings, etc. The format of this record is documented the same way IRRDBU00 output is documented in the z/OS Security Server (RACF) Macros and Interfaces manual. Sample DB2 load and table statements are provided for this new record type.

The irrhfsu utility can be invoked as a UNIX command, or from batch using the BPXBATCH program. It can be run against the entire file system, or a list of subtrees within the file system. The output can be appended to your IRRDBU00 output so you can combine the data within a relational database for integrated queries.

The irrhfsu utility consists of these files:

You can download these files either by using your browser or by using anonymous file transfer protocol (ftp). From your browser, select "file" and "save as". For anonymous ftp, use the site ftp.software.ibm.com. irrhfsu can be found in the directory /eserver/zseries/zos/racf/irrhfsu/. Full installation instructions are in the HFSUnloadReadMe.pdf file.

We welcome your comments and questions on the irrhfsu utility. Please direct them to the RACF-L mailing list. Subscription information for RACF-L can be found from the RACF-L Discussion List Page.
