In terms of interoperability and compatibility, every time new applications and database levels are released, a thorough compatibility check is conducted in PowerHA. IBM consistently ensures compatibility, especially in the open systems environment and within the Unix platform, where software compatibility challenges are prevalent. Regarding components controlled under PowerHA, IBM occasionally must address compatibility issues by providing fixes and releases. Despite this, the product exhibits stability. However, the main issue arises when components are updated, requiring IBM to release corresponding fixes. This process may take some time, but it is routinely addressed. Regarding product stability, PowerHA is generally reliable, with the only notable challenge being the need for fixes during component updates. It would be beneficial if the software had options for controlling and implementing an active-active setup, although PowerHA is primarily designed for active-passive configurations.
