Installing and Configuring Software

Use DSM/SCM to install and manage new and revised software products from HP or

third-party vendors. HP delivers release version updates (RVUs) on a site update tape

(SUT) on one or more tapes. SPRs are usually delivered on a backup tape or through

a network connection.

You can choose when DSM/SCM requests are executed, but you must perform all

requests in the specified order.

Receive the software into the DSM/SCM archive on your host system. DSM/SCM

receives SPRs independently into the archive, then rolls up the SPRs when you use

Copy to or Copy matches. This procedure allows DSM/SCM to be able to show

exactly which files changed in which SPRs and allows you greater flexibility in

managing configurations. To create a list of the products to be installed called a new

software revision, you select software stored in the archive.

A Build request readies the software to be placed on the target system by an Apply

request. The Build creates a new configuration revision that contains the product

versions, an operating system image, and relevant DSM/SCM profile items such as the

location of the target subvolume.

An Apply request places the configuration revision on the target system using

temporary file names. Guardi

an files for a target system are placed in a TSV. OSS

files are placed in a target directory location (TDL). A snapshot of the target’s new

configuration is received into the host database to update the host’s record of the

target’s software configuration.

From there the software is renamed, put in its proper functioning location, and then

activated. You must run ZPHIRNM before performing a system load if one is required.

You use ZPHIRNM to change the temporary file names to their real names. ZPHIRNM

deletes the temporary files and overwrites any existing files with the same names that

need to be replaced. ZPHIRNM also renames all the currently running files to

temporary file names. You can use these files later if you need to back out a revision.

ZPHIRNM is run independently of all other processes, so you can minimize application

downtime and schedule it for a time most convenient for your work environment.

Caution. Inputs to the archive must be received as delivered from HP. Do not overlay SPRs

into product distribution subvolumes (DSVs) before receiving the software into the archive.

Note. For H/J series systems where SUT is delivered through CD/DVD, the

IPSetup User's

Guide needs to be followed to place the files on the NonStop Systems. IPSetup starts the

$ZRVU process and thus helps the Planner Interface to perform Receive Software activity.

Note. When a Gxx SUT that contains both the heap manager products (T8431 and T1269) is

copied to the new so

ftware revision, the Heap Manager Selection dialog box is displayed. This

feature is supported only on systems running G06.29 and later G-series RVUs. After selecting

the desired heap manager product, click the Continue button to copy the SUT to the new

software revision. To cancel the Copy to operation, click the Cancel button.
