Must have the point of learning:
Identify customer's needs (for example, architecture, scalability, physicalrequirements, and so on). Understanding of user needs Establish strategy for crisis recovery. Formulate a disaster recovery strategy Install base operating system. Install the Base Operating System Perform initial configurations (for example, networks, paging space, date / time, root password, and so on). the initial configuration Chapter 1. Certification overview 3 install LPPs. install LPPs install and configure other software systems (for example, Netscape). Installing and configuring other software systems Apply software Updates. Receive the software upgrade Remove Software. Uninstall Software Upgrade Operating System (for Example, Preservation and MigrationUpgrades). Upgrade the operating system (reserved or merging upgrade)? ? ? Create and install a mksysb to create and install a mksysb Upgrade hardware. Upgrading hardware Configure printers and queues (for example, add, change, show, or deleteprinters and queues). Configuring printers and queues Configure and manage resources (for example, manage cron, configureskulkers, configure power management). configuration and management of resources configure devices (for example, cfgmgr, TTY, parallel and manual devices). configure device configure subsystems and subservers (for example, start / stop systemresource manager). Configuring subsystems and sub-server Problem determinationThe following are the problem determination topics. Troubleshoot problems with hardware installation (for example, cableconnections). installation hardware failure judgment Troubleshoot problems with software installation (LED hang, system hang). software installation failure judgment (system hang) Troubleshoot problems with software (disk space, prerequisites, lslpp, and soon). software fault diagnosis Troubleshoot hardware (for example, hardware parameters, cfgmgr, prerequisites, ODM tools). troubleshooting (using similar cfgmgr and other tools) Evaluate performance and resource problems (for example, Check Log Files, Skulkers, PS - EF. Evaluation Performance and Resources Question (for example, check the log file, using Skulkers, PS-EF, etc.)
System and user maintenanceThe following are the system and user maintenance topics. Identify suspect hardware components before hard failure by monitoring errorlogs. By looking at the error log, prior to the identification of hardware failure of hardware components Install necessary patches problematic to prevent known problems. Install the necessary The patch to avoid the problem of Reboot Servers (Gracefully). Ratse Server Add, Delete, And Modify Users. Increase, Delete, and Modify User
Modify user environment (for example, modify initialization files, edit .profile, edit dtwmrc, and so on). Modify user environment Modify system environment. Modify the system environment Work with Volume Groups (add, import, remove, export, modify, list, And soon. Use VG Work With Physical Volumes (Add, List). Using PV Work with Logical Volumes (Add, Remove Modify, List, And So On). Work with File Systems (For Example, Create, Remove, Modify, List , and so on). Modify paging space (increase size, add, remove, activate, list, and so on). Troubleshoot file system problems (for example, mount / unmount problems, file system full, and so on). Troubleshoot paging space problems (for example, low paging spaceconditions). Troubleshoot device related problems (for example, file system not availableat IPL, volume group not varying on IPL, SCSI device problems, and so on). Back up the system. Back up the applications . RESTORE FILES from Tape. Establish A Backup and Recovery Process Based Upon CustomerRequirement s. Recover the system.CommunicationsThe following are the communications topics. Install device driver. Work with TCP / IP daemons (for example, start and stop TCP / IP daemons). Create interface (set IP address, set subnet mask, configure DNS) . Configure interface (define node, gateway). Modify interface (change IP parameters). Configure TCP / IP services. Work with NFS (for example, start and stop NFS). Export directory (exportfs). Mount remote file system.
