Simplifying single-system management on HP-UX 11i (SMH) (538076-002; March 2011)

or date. Policy changes can be automated so that no operator or administrator action is

required.)

• Is aware of users defined in netgroups (defined in the file /etc/netgroup), which saves time

during configuration and is invaluable in networked computing environments

• Supports allocation of resou rces among up to 256 PRM groups (partitions of the HP-UX

instance)

• Supports allocation of resources in a hierarchical manner, where a PRM group’s resources

are divided among its subgroups

• Enables you to create Secure Resource Partitions, which combine HP-UX 11i v2 security

capabilities with the resource management capabilities of PRM

• Can scan UNIX® accounting files for data on the specified resource (CPU, real memory,

and disk I/O bandwidth) and then order the accounting records by user, UNIX group,

command name, or PRM group (This feature helps in better understanding resource usage

for capacity planning purposes and for fine-tuning resource allocation configurations.)

Distributed Systems Administration Utilities

Distributed Systems Administration Utilities (DSAU) signif icantly improves the management of

HP Serviceguard clusters and groups of distributed systems. DSAU is based on open source

tools cfengine, pdsh, and syslog-ng and consists of three primary components:

• Configuration synchronization

• Consolidated logging

• Command fanout

Web-based interface is available for consolidated logging and configuration

synchronization. One of the features that DSAU offers is the consolidated logging feature that

is integrated with the HP SMH. The consolidated logging feature is leveraged from Syslog-

NG – Syslog Next Generation, which is an open source tool. It is a fine replacement for

Syslog and has the following benefits:

• Offers standard UDP and additional TCP transports

• Allows consolidation of arbitrary text based log files

• Allows sign ificantly more powerful filtering and log rotation

It is a standard feature of the UNIX syslog daemon to be able to forward syslog messages

through UDP to a remote log file consolidator or “syslog sink.” There a re several issues with

this approach. First, it is UDP-based so it is possible to lose messages. Second, it applies to

syslog data only.

DSAU provides several extensions in this space. The data can be transported through UDP or

TCP. Using TCP offers the ability to increase the security of the data on the LAN using tools

like SSH tunneling to encrypt potentially sensitive syslog data. Also, arbitrary textual log files

can be consolidated.

It is especially useful in a Serviceguard cluster in which the per-member package logs can

now be consolidated into a single file to ease maintenance and problem diagnosis. DSAU
