HACMP INTERVIEW QUESTION AND ANSWER

Does HACMP work on different operating systems?

Yes. HACMP is tightly integrated with the AIX 5L operating system and System p servers allowing for a rich set of features which are not available with any other combination of operating system and hardware. HACMP V5 introduces support for the Linux operating system on POWER servers. HACMP for Linux supports a subset of the features available on AIX 5L, however this mutli-platform support provides a common availability infrastructure for your entire enterprise.

 

What applications work with HACMP?

All popular applications work with HACMP including DB2, Oracle, SAP, WebSphere, etc. HACMP provides Smart Assist agents to let you quickly and easily configure HACMP with specific applications. HACMP includes flexible configuration parameters that let you easily set it up for just about any application there is.

 

Does HACMP support dynamic LPAR, CUoD, On/Off CoD, or CBU?

HACMP supports Dynamic Logical Partitioning, Capacity Upgrade on Demand, On/Off Capacity on Demand and Capacity Backup Upgrade.

 

If a server has LPAR capability, can two or more LPARs be configured with unique instances of HACMP running on them without incurring additional license charges?

Yes. HACMP is a server product that has one charge unit: number of processors on which HACMP will be installed or run. Regardless of how many LPARs or instances of AIX 5L that run in the server, you are charged based on the number of active processors in the server that is running HACMP. Note that HACMP configurations containing multiple LPARs within a single server may represent a potential single point-of-failure. To avoid this, it is recommended that the backup for an LPAR be an LPAR on a different server or a standalone server.

 

Does HACMP support non-IBM hardware or operating systems?

Yes. HACMP for AIX 5L supports the hardware and operating systems as specified in the manual where HACMP V5.4 includes support for Red Hat and SUSE Linux.
