C++ (G06.20)

The G06.20 RVU includes a fully ANSI 98-compliant C++ run-time library, designated

as the C++ v3 run-time library (v3 RTL). Starting in G06.20, you have a choice of three

different C++ language dialects: v1, v2, and v3. The default compiler dialect setting is

changed from v1 to v3. The build file for any product that invokes a TNS/R native C++

must be examined and changed according to certain rules that are documented in the

Interactive Upgrade Guide.

DSM/SCM (G06.18 through G06.26)

Since the introduction of G06.18, if you had to fall back from an RVU that did not have

installed the D46 DSM/SCM PVU, you had to run the DSM/SCM FALLBACK macro

from the ZDSMSCM subvolume. If a D46 PVU existed, you did not have to run the

FALLBACK macro. However, for the G06.26 RVU, you must run the FALLBACK macro

if you have not installed the T6031D46^ABK SPR introduced in G06.25. The

interactive macro must be run by the DSM/SCM owner or by super ID (255,255). The

FALLBACK macro reverts the DSM/SCM Host or Target, or both, database back to a

pre-T6031D46^ABN state.

If you perform a backout to your previous pre-T6031D46^ABK SPR after having

installed T6031D46^ABN, the FALLBACK macro only removes the Safeguard alias

and Guardian user security profile information. DSM/SCM still retains OSS

management information. New users must be reconfigured in DSM/SCM. See the

DSM/SCM Users’ Guide for more information and DSM/SCM (T6031D46^ABN) and

the G06.26 RVU on page 1-5.

DP2 (G06.16, G06.23, and G06.24)

If you set the AUDITTRAILBUFFER or the SQLMXBUFFER attribute to 128 or more,

you need to reset these values to 0 before falling back to G06.16 or an earlier RVU. If

you fail to do so, TMF might not start, or a disk volume might go offline. You can

recover from this situation by using the SCF ALTER command. See the Interactive

Upgrade Guide for details.

If you are planning to use SQL/MX Release 2.0, HP recommends that you apply one of

these DP2 fallback SPRs on your current SYSnn before upgrading to G06.26:

•

T9053AOY, or later if the system uses the online disk remirror feature

•

T9053AOZ, or later if the system does not use the online disk remirror feature.

After installing the fallback SPR, test it sufficiently for production use. Then, migrate to

G06.26. If you are using SQL/MX Release 2.0, and you have to fall back to a previous

RVU, and you have created SQL/MX objects or audit records, you must have this

fallback SPR installed on your current SYSnn.
