Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
Words and Phrases
| Search for | Example | Results |
|---|---|---|
| A single word | cat
|
Topics that contain the word "cat". You will also find its grammatical variations, such as "cats". |
|
A phrase. You can specify that the search results contain a specific phrase. |
"cat food" (quotation marks) |
Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase. |
Using Boolean Operators
| Search for | Operator | Example |
|---|---|---|
|
Two or more words in the same topic |
|
|
| Either word in a topic |
|
|
| Topics that do not contain a specific word or phrase |
|
|
| Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
| A combination of search types | ( ) parentheses |

Overview
High Availability Cluster Multiprocessing (HACMP) is an IBM solution for high-availability clusters on the AIX UNIX and Linux for IBM System p platforms.
HACMP can run on up to 32 computers or nodes, each of which is either actively running an application (active) or waiting to take over should another node fail (passive). Data on file systems can be shared between systems in the cluster.
HACMP relies heavily on IBM's Reliable Scalable Cluster Technology (RSCT). RSCT includes daemons that are responsible for monitoring the state of the cluster (for example, a node, NIC or network crash) and for coordinating the response to these events. HACMP is an RSCT aware client. RSCT is distributed with AIX.
The IBM_HACMP package discovers HACMP on AIX via TTY (SSH or Telnet protocols). The package follows the discovery model to discover the HACMP Topology (configured networks, node interfaces-both public TCP/IP and serial heartbeat, and service IPs) and Application Resources (configured resource groups, application servers, and volume groups). The package maps the configured public interfaces to UCMDB IPs, serial interfaces to directories beneath the UCMDB hosts, as well as volume groups to logical disks beneath the UCMDB host, and Application Resources to the Topology.
