HP-UX Secure Resource Partitions (SRP) A.02.01 Administrator's Guide

performed when the SRP is started or stopped, such as notifying management or auditing

systems, or mounting the SRP home directory (/var/hpsrp/srp_name).

NOTE: If you are using shared storage to mount the SRP home directory to facilitate

cloning of an SRP, consider using the SRP setup script to automatically mount and

unmount the SRP home directory. In addition to ensuring that the home directory is

available when the SRP is started, it will also help prevent the accidental deletion of

the home directory when deleting one of the SRP clones.

• fstab: Each SRP has a file system mount table configuration file that replicates the system

file system mount table described in fstab(4M). This file

(/var/hp/hpsrp/srp_name/etc/fstab) may be accessed and edited from within the

SRP. The start script (/var/hpsrp/srp_name/sbin/init.d/srp_mount) performs

the mounting and unmounting of file systems when the SRP is started and stopped.

5.3 Deploying Applications in an SRP Environment

HP recommends that you execute most applications from within an SRP environment. The INIT

compartment should be reserved for the execution of system management activities. Note that third

party system management utilities should also be executed in the INIT compartment. If you chose to

deploy a system management utility within an SRP, you may find it necessary to customize the SRP

compartment access rules to provide any increased capabilities necessary for the utility to perform its

services.

This section describes the following topics:

• 5.3.1 Single Instance Applications

• 5.3.2 Multi-Instance Applications

• 5.3.3 Deploying Applications with the Application Templates

• 5.3.4 Ensuring access to application files located outside the SRP home directory

• 5.3.5 Best Practices for Application Deployment with SRP

5.3.1 Single Instance Applications

While nearly all applications can be executed within an SRP environment, some applications do not

support multiple instances of the same application executing on the same system concurrently. For

these applications, HP recommends that you do not run multiple instances of these applications, even

when the instances are located in separate SRPs, HP recommends that you install the application

under the /var/hpsrp/srp_name/ directory if supported by the vendor.

5.3.2 Multi-Instance Applications

There are two models to deploy multi-instance applications within an SRP environment:

• Shared executable: In this model, the application is installed once per system in a shared

location. The application may require a set of files to be replicated and configured per

instance. HP recommends that you locate per instance files under the

/var/hpsrp/<srp_name/ directory when supported by the vendor.

• Per-SRP installation: For applications that support multiple installations per system, you can

install the application for each SRP in which it will be executed. HP recommends that you

install the application under the /var/hpsrp/srp_name/ directory if supported by the

vendor.
