Increasing HPUX 10.20+ FileSystem to Handle File Sizes > 2GB

If you have a very large database whose compressed export cannot be contained within 2GB, you may be able to change the configuration of your $EXPORTS filesystem to handle files > 2GB (2,097,152,000 bytes). Below are notes from Oracle WorldWide Support on changing filesystems on HPUX versions 10 and 11:

Summary File Limits for Oracle on HP
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
See <Note:62427.1> for generic 2Gb information.

Max filesystem size:
        <= HP-UX 10.10            4Gb
        >= HP-UX 10.20          128Gb
        >= HP-UX 11.00          128Gb

Max OS file size:
        <= HP-UX 10.10            2Gb
        >= HP-UX 10.20          128Gb
        >= HP-UX 11.00          128Gb

Ulimit for filesize:
        Shell           Query/Set               Defaulted In
        -----           ---------               ------------
        ksh / sh        ulimit                  /etc/profile
        csh             limit [-h] filesize     /etc/csh.login

If you have problems with files >2GB see the following matrix:

Release         System  Device    I/O           Import    Loader

  7.1.6            2Gb   2Gb      raw only      2Gb         2Gb

        SIL = System Imposed Limit
        Limits apply to HPUX 10.20 and 11.0

The 'largefiles' option is required to support large files on a filesystem. The following example shows how to convert a no-large-files filesystem to a large-files filesystem:

/usr/sbin/fsadm -F vxfs -o largefiles /oracle
or
/usr/sbin/fsadm -F vxfs -o largefiles {special device file}
