AIX 5L new feature

AIX 5L New Features 1 Start support Linux with Linux compatibility IBM, add it in AIX. In Aix 5L and AIX 4.3.3 Episode 8 Maintenance, you can run the Linux application tools and usage, with the same Linux appearance as KDE-2 with GNOME on the AIX Power machine. This machine Linux program can be run in AIX, you can put the Linux application source code in AIX, recompile the application to generate a new AIX program. There are three mechanisms to achieve compatibility with Linux. The first is the toolbox for the Linux application. The second mechanism is through the application interface (API). The third is to recompile Linux source code in AIX. 2 The new volume group feature now has a read-only volume group, just an important new feature, which can add data protection in a read-only and static environment. In addition, the volume group identifier (VGID) increases from 16 characters to 32 characters, which is consistent with the physical volume identifier (PVID). The hot space function also added a volume group. 3 JFS2 file system utilizes JFS2 file system, up to 4PB, but this is only the theoretical limit, the actual file system length is 1TB. In addition, JFS2 file systems do not need to worry about I node issues because this is dynamically assigned. JFS2 also supports 32-bit kernels, but the use of 64-bit kernels can improve performance. 4 Hot Synders of Newly added MIGRATELP commands can manage logical partition-level storage. If the disk encounters a hotspot, you can move the hotspot partition on a less active disk. With the migratelp command, you can control the specific location of a particular logical partition. To look for hotspots, use the lvmstat command and the -e option to open statistics. Start collecting # lvmstat -e -v rootvg stop collection # lvmstat -d -v rootvg To browse VG statistics with LV, use # lvmstat -v rootvg to use LP flow to LV statistics, use #lvmstat -l HD3 5 32 bits When you install AIX 5L with 64-bit kernels, you can choose 32-bit kernels and 64-bit kernels. In most cases, this choice is not particularly important, and the 32-bit kernel supports 64-bit applications with 64-bit kernels. Bootinfo -y command Displays whether the system allows 32-bit or 64-bit bootinfo -k commands to return the current system kernel mode SVMON -P command Displays the current running process is 32-bit or 64-bit, whether it is multi-thread. The system is currently running in 32 bits, to switch to 64-bit mode, you can use the following command, but first install BOS.mp64 file set # ln -sf / usr / lib / boot / unix_64 / unix # ln -sf / usr / LIB / BOOT / UNIX_64 / USR / LIB / BOOT / UNIX # bosboot -ak / usr / lib / boot / UNIX_64 # Shutdown -fr Restart, switch to 64-bit mode 6 system monitoring and control subsystem newly increased The system is called resource monitoring and control subsystem (RMC, Resource Monitoring and Control). This subsystem is a system that can monitor predefined and user-generated events and tasks. There are 84 predefined conditions that set a threshold level, response trigger level. 7 AIX has supported UNIX SYSTEM V Print Features 8 System Pause Check System Pause Check Features You can define the operation of the system load overweight. The newly added SHDAEMON monitor can monitor the functionality of the system running process.
