As for zFS files systems: A new version 5 format was introduced with z/OS V2.1, which stores directory information differently. It is supposed to be much mor performant for large directories, i.e. directories with large numbers of entries. I seem to remember that some test were done at my former employer. It was about really large directories in a WAS environment. Performance improved dramatically, if I remember correctly. Look for "version4" and "vdrsion5" in the zFS Asministratin Guide. You can convert an existing v4 file system to v5 online unsing "zfsadm convert ...". -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
