TNS/R CRE Heap Manager (G06.15)
TNS/R CRE Heap Manager (G06.15)
The G06.15 RVU introduced a new heap manager, NSK CRE/RTL (T1269), an
alternative to the Native CRE/RTL product (T8431). Either heap manager can be
chosen during the creation of a system configuration revision. Consequently, the
choice of which one to install is an independent decision for your system. See S02001
for migration considerations and S03104 for installation instructions.
Note that if you are installing and using OSM, HP recommends that the NSK CRE/RTL
(T1269) product be installed on the system, as opposed to the Native CRE/RTL
(T8431), which is the default. Refer to the Support Note S02001 for migration
considerations for T1269.
TSM Client and Server Software (G06.24, G06.25, G06.26,
G06.27)
Part of the G06.27 installation process might involve upgrading your system console to
TSM client software Version 2005A.
If you have to fall back to an earlier RVU after installing G06.27, you can continue to
use TSM client software Version 2005A on your system console.
The TSM Low-Level Link now resembles the OSM Low-Level Link application in its
representation of objects and resources.
TSM does not support or adequately support these new features, beginning with the
G06.21 RVU:
•
Online disk remirroring (ODR) (G06.21). Only OSM automatically recognizes
online remirrored disks. TSM can recognize online remirrored disks only if $ZTSM
is aborted and then restarted.
•
HP NonStop ServerNet cluster (G06.21). HP recommends using the OSM Service
Connection (rather than the TSM Service Application) for all systems that are part
of an HP NonStop ServerNet cluster.
•
HP Ultrium Linear Tape Open (LTO) Tape Drive (introduced in the G06.21 RVU).
•
The new digital audio tape (DAT) drive for use on NonStop S-series systems
compatible with G06.23.
•
The I/O adapter module (IOAM) enclosure (introduced in the G06.24 RVU) and its
related components for use on S76000 NonStop S-series systems and above.
•
Enterprise Storage System (ESS).
Caution. You cannot simultaneously use both heap managers (T8431 and T1269) on the
same system.
Note.
HP recommends that you always install the latest TSM server SPR and client and that you
install at least the G06.24 client and server SPRs before performing an online boot code update.
