WPAR (working load is divisional) it is IBM®AIX®610 in accessary permissive process product. The article reachs the relevant idea that introduces WPAR to you his to configure. Through learning the give typical examples in the article, your aux will be able to is in quite system and DB2 of the implementation in applying program WPAR®installation and configuration.
Overview
WPAR is an independent moving environment, in AIX computer of the standard it has its Init process. To final user, WPAR is like the AIX computer that is an independence, because it has a group of its processes, the AIX computer of this and standard is very similar. Below introduction of article general key a few concepts, it is very valuable that these concepts set DB2 environment to be in WPAR:
The type of ◆ WPAR (system and applied process WPAR)
◆ founds systematic WPAR
◆ is installed in WPAR and configure DB2
The specification that article place provides and skill can be being installed and configure DB2, Oracle, IDS, WebSphere®When waiting for all sorts of products, Application Server and SAP provide a help for WPAR user.
The type of WPAR
WPAR can be divided for system and applied process WPAR two kinds.
◆ system WPAR is standard AIX computer (I am those who say ” of environment of “ overall situation) in a process of the executive environment that has oneself. It provided all standards for final user (/ , / Usr, / Opt, / Var, / Etc, / Tmp and / Home) file system. Systematic WPAR can be used read-only mode shares global environment medium / Usr or / Opt, OK perhaps use oneself / Usr or / Opt file system. Can use 3 kinds of different kind to deploy the file system in systematic WPAR: Use share / Usr and / Opt (namely Namefs type) , use illicit some / Usr and / Opt, and use system of file of root of long-range ” of so called “ (their configuration is NFS type, the likelihood is Nfsv3 and Nfsv4, hang from NFS server carry) .
WPAR of ◆ application process is a process of the executive environment that he has in global environment computer likewise, and use all file system in global environment. Applied process WPAR uses the script that start to undertake starting, and the end after its carry out a process is achieved in the script that start. For example:
Wparexec -n "application Wpar Name" "absolute Path Of The Script To Be
Executed With Arguments If Any "
# Wparexec -n Appwpar /usr/bin/sleep 10
Starting Workload Partition Appwpar.
Mounting All Workload Partition File Systems.
Loading Workload Partition.
Loading Workload Partition.. ----Script Will Start Execution Here----Script Will Start Execution Here
Shutting Down All Workload Partition Processes.
This give typical examples will start Appwpar, carry out given script. In this give typical examples, the operation that has is Morpheus 10 seconds. Applied process WPAR will be in Morpheus is stopped by oneself after 10 seconds.
