AIX LKU improved performance for checkpoint/restart of shared memory attachments to reduce blackout duration.
Customers using AIX Live Kernel Update driven by PowerVC in an environment with many shared memory attachments will benefit by being able to reliably use LKU without losing connection or having other consequences of a long blackout period in LKU.
AIX JFS2 is missing noexec option to prevent executing binary files from a JFS2 filesystem. Some filesystems are just data system without any executables and according to security requirements the execution of unwanted executables must be prevented.
Improve errpt CORE_DUMP entries to refer back to executable image that was running
When using dbx to analyze a core file that was dumped, the executable binary that was running must be used in combination with the core file to identify the exact instruction that caused the core dump. In the errpt CORE_DUMP entry there is the ful...

When lrud free the memory, it will enable the interrupt disabled mode and block other threads. When customer runs the time-sensitive applications, it might lead to an application time out and then the transaction failures.
Request for better messaging during the liveupdate (LKU) process
Apple needs a way to determine if AIX LKU is taking too long during the blackout phase. A separate idea AIX-I-685 is open for adding a timeout value, and this RFE is open to break out the separate request from Apple for more information during the...
