Memory “rules of thumb” – PA-8700 system minimums • 1.
Memory “rules of thumb” – when to add more • For memory-intensive applications (such as those using 4GLs) • For heavy batch processing • For a high number of online user sessions • When 7/22/2008 adding processors to a system page 22
New features of MPE/iX 7.5 — FibreChannel • Native FibreChannel PCI I/O cards are now supported in N-class and A-class systems, allowing FibreChannel disks to be directly connected to these systems. • Provides greater I/O bandwidth than Ultra SCSI or Fast/Wide SCSI, which can help greatly on systems with heavy disk I/O.
New features of MPE/iX 7.5 — FibreChannel • FibreChannel benchmarks show big performance gains for disk-intensive processing. • Six new system processes were added to MPE/iX 7.5 for FibreChannel, so the Transaction Manager (XM) Checkpoint Processor now starts with System Process 17, instead of Process 11.
New features of MPE/iX 7.
New features of MPE/iX 7.5 – TurboIMAGE Scalability II • Enhanced High Water Mark (EHWM) may provide improved concurrency for DBPUT and DBDELETE on busy OLTP systems. • Can provide even greater scalability than the existing DSEM and Prefetch options. • Disabled by default; enabled with DBUTIL. • Best performance improvement is seen on systems with six or more processors.
New features of MPE/iX 7.5 — PLFD Expansion •A process can open more files and/or sockets, up from 1024 to 4096. •A new hashing algorithm provides better performance when a process has more than 512 files and/or sockets open.
Other new features of MPE/iX 7.5 • The number of users that can connect to a single user logging process has been increased from 1140 to 2851. • LDEV 1 can now be greater than 4GB in size. MPE/iX system files must still reside in the first 4GB on this disk.
Review of some recent high-end features • An N4000 system can now have up to 12000 processes, by enabling the “BIGPIN” feature in SYSGEN (introduced in 7.0 Express 1). • Systems needing additional processes can replace the :RUN command with the :NEWCI command, to eliminate one process per user (introduced in 6.5).
MPE/iX 6.5 and 7.0 performance patches • Two patches were released in 2001, which may improve performance on some larger systems running MPE/iX 6.5 or 7.0: – – MPELXH8 (Memory Manager) MPELXH3 (TurboSTORE) • Both 7/22/2008 patches are included in MPE/iX 7.5.
MPE/iX 6.5 and 7.0 performance patches • The latest 6.5 and 7.0 Power Patch releases also contain these patches. • 6.5 Power Patch 3 includes: - MLELXQ5, which superseded MPELXH8, and - MPELXY4, which superseded MPELXH3. • 7.0 Power Patch 2 includes: - MPEMXB2, which superseded MPELXH8, and - MPEMX64, which superseded MPELXH3.
