Configure NodeManager

===========================
Configure NodeManager
========================
1- D:\oracle\Middleware\wlserver_10.3\server\bin>setWLSEnv.cmd

2- D:\oracle\Middleware\wlserver_10.3\server\bin>uninstallNodeMgrSvc.cmd

Stopping Oracle WebLogic NodeManager (D_oracle_Middleware_wlserver_10.3).
Oracle WebLogic NodeManager (D_oracle_Middleware_wlserver_10.3) stopped.
Oracle WebLogic NodeManager (D_oracle_Middleware_wlserver_10.3) removed.

3- Edit installNodeMgrSVC.cmd with the following parameter

set NODEMGR_HOST=(your host name)
4- Run installNodeMgrSVC.cmd

5- Crash recovery, we want to enbale nodemanager to restore server to their last known state after reboot

open nodemanager.properties & change CrashRecoveryEnabled=true
also for Smartupdate that manages weblogic patches it is adviceable to put

StartScriptEnabled=true
Also because the domain's script bin\startWeblogic has classpath configured which use smartupdate that manage Weblogic Patches
U will need to change StartScriptEnabled=true in nodemanager.properties file

6- stop/start node manager after update nodemanager.properties

Enroll the domain with nodemanager
----------------------------------
USE WLST Commond line

Reducing disk I/O on Oracle database

How do we reduce disk I/O in UNIX? There are three generally accepted techniques for the DBA to reduce disk I/O:
1-Tune SQL statements to retrieve data with a minimum of disk I/O - This is generally performed by finding large-table full-table scans and replacing the full-table scan with an index scan.

2- Change the Oracle SGA - When we increase the shared_pool_size, large_pool_size, or db_cache_size, the resulting performance improvement is related to the reduction in disk I/O.

3-Reorganize tables to reduce disk I/O – This is done by selectively moving tables to tablespaces with a different blocksize, and re-sequencing table rows into the primary key
