TNS/R CRE Heap Manager
TNS/R CRE Heap Manager
The G06.15 RVU introduced a new heap manager, NSK CRE/RTL (T1269), an 
alternative to the Native CRE/RTL product (T8431). You can choose either heap 
manager during the creation of a system configuration revision. Consequently, the 
choice of which one to install is an independent decision for your system. For migration 
considerations, see Support Note S02001. For installation instructions, see Support 
Note S03104. 
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. For migration considerations for T1269, see CRE/RTL 
(T8431, T1269) on page 4-17 and Support Note S02001.
TSM Client and Server Software
HP recommends that you always install the latest TSM server SPR and client. 
TSM client software is backwards compatible. If you have to fall back to an earlier RVU 
after installing G06.29, you can continue to use your upgraded TSM client software on 
your system console.
Beginning with TSM client T8154ABI (TSM 2005A), the TSM Low-Level Link is 
replaced by the OSM Low-Level Link. Installed by the TSM installer, the OSM Low-
Level Link looks and functions much like the TSM Low-Level Link. To learn about the 
minor differences between the OSM and TSM versions, SeeTSM and OSM Client 
Applications on page 1-2, or the TSM ReadMe file. 
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 later.
Caution. You cannot simultaneously use both heap managers (T8431 and T1269) on the 
same system.
Note. You install TSM server T7945ABN or later and TSM client T8154ABG or later before 
performing an online boot code update.
