OSS Large Files
2. Format 1 files are automatically converted to Format 2 when opened using the OSS
64-bit utilities or Enscribe.
The ability to access large files can lead to problems if you install the H06.06 or later
RVU, then need to fall back to an earlier RVU. Format 2 files are not supported in pre-
H06.06 RVUs; if your applications have created new Format 2 files (large or small),
those files cannot be accessed on a pre-H06.06 system.
DP2
A DP2 fallback SPR, T9053AQM, is available. This fallback SPR is preinstalled in
H06.05 systems, so for those systems, no action is required. You can install the
fallback SPR on systems running H06.03 or H06.04, as long as all the prerequisites
are met:
•
If you are currently running the H06.03 RVU, consider upgrading to H06.05 before
upgrading to H06.07 so as to facilitate fallback if fallback becomes necessary.
•
If you are currently running the H06.04 RVU, HP strongly recommends that you
install the fallback SPR before migrating to H06.07. If you do not install the fallback
SPR before migrating to H06.07, you must install it during fallback to ensure a
successful fallback.
The installation of T9053AQM requires a system load.
Falling back to H06.03 is not supported.
Once the T9053AQM fallback SPR is installed:
•
Format 2 OSS files smaller than the 2 GB limit are converted to Format 1 when
opened, so that the files remain usable. The file size cannot exceed the Format 1
limit.
•
Format 2 OSS files larger than the 2 GB limit are no longer accessible through the
OSS file system and utilities, and DP2 returns an error for any operation other than
purging the files. However, the files can be accessed from the Guardian
environment by using Enscribe.
Note that files smaller than 2 GB that were converted to Format 2 on H06.06 or
later appear initially to most utilities (except DSAP/DCOM T9543H01^ABH) as
zero-size Format 2 files after fallback. When the files are accessed for the first time
after the fallback, they are converted to Format 1 and show their actual size.
If the DP2 fallback SPR is not installed, you cannot access any Format 2 files using
either OSS or Enscribe on a pre-H06.05 system, even if the files are smaller than 2
GB.
WARNING. Ifyou do not install the DP2 fallback SPR before migrating to H06.07 and a fallback
becomes necessary, you must perform a system load on the prior RVU, and then, before using
any OSS files, you must install and coldload to the DP2 SPR.
