  4. Pre OS - Tasks • You are deploying an integrated system… • Read the Oracle documentation • Make deployment choices: • Oracle 9i RAC DB: raw partitions or OCFS for shared storage? • Oracle Collaboration Suite: Storage: infrastructure, storage: use existing OID, DB, etc, or deploy new servers. • Select and implement a hardware topology… Ex: RAC… • Gather system components • Supported Oracle software, patches, etc. • OS software, errata updates, etc. • Hardware components: servers, switches, HBAs, disks, cables, etc. • Check Oracle minimum/recommended hardware requirements • Ensure latest supported BIOS, firmware, drivers.

  9. OS Installation - Tasks OS installation must: • Follow IT environment guidelines for deploying Linux hosts • Update kernel and other OS errata, both for Oracle functionality and OS robustness, for example: • binutils, pdksh – 9iAS • e25 kernel, pdksh – 9i RAC • Update hardware drivers, for example: • megaraid, qla2300_6x, bcm5700, e1000 • Partition boot drive (Oracle product specific), for example: • swap, /, /usr, /var, /tmp, /home, /opt, etc. Techniques Kit Pre OS OS Install Pre Oracle Oracle Post Oracle

  10. OS Installation – CD-ROM OS installation can be achieved via: • OS CD-ROM based install • PXE based network install • Redeployment partition CD-ROM based install / (sda1) /usr /var /home /opt/oracle /tmp swap Techniques Kit Pre OS OS Install Pre Oracle Oracle Post Oracle

  11. OS Installation – Network OS installation can be achieved via: • OS CD-ROM based install • PXE based network install • Redeployment partition Network install / (sda1) PXE / DHCP Server /usr /var /home /opt/oracle /tmp swap Techniques Kit Pre OS OS Install Pre Oracle Oracle Post Oracle

  12. OS Installation - RP OS installation can be achieved via: • OS CD-ROM based install • PXE based network install • Redeployment partition RP based install RP (sda1) / /usr /var PXE / DHCP Server /home /opt/oracle /tmp swap Techniques Kit Pre OS OS Install Pre Oracle Oracle Post Oracle

  13. OS Installation – RP Details • Dell recommends the use of a redeployment partition • The RP can be created via CD-ROM, network, or imaging • RP enables rapid redeployment • RP ensures consistent install on all servers (IT compliance, RAC) • Enables scale out (grid) computing from the OS layer • Key difference w/ Network-based is self-reliance Traditional Partitioning +RP Partitioning / (sda1) RP (sda1) /usr / /var /usr /home /var /opt/oracle /home /tmp /opt/oracle swap /tmp swap Techniques Kit Pre OS OS Install Pre Oracle Oracle Post Oracle

  14. OS Installation – RP Contents 1 • RP must be the first partition on bootable drive i.e., /dev/sda1 or /dev/hda1 • Use standard DOS style MBR and mark RP partition active • RP directories: /boot Contains grub / lilo boot loader /linux Contains kernel (vmlinuz) and ramdisk (initrd) /ks.cfg RH Kickstart configuration file, contains RH install information such as partitioning, network setup, X-windows setup, etc. /Oracle Contains Oracle Product Disks /RedHat Contains RedHat OS Disks Techniques Kit Pre OS OS Install Pre Oracle Oracle Post Oracle

  15. OS Installation – RP Contents 2 • RP directories cont’d: /custom/scripts Scripts that can be called from ks.cfg (%post) /custom/rpms RPMS for errata, drivers etc, installed from a script in ../scripts /custom/files Files (.tar, .gz, .txt etc), needed during installation Techniques Kit Pre OS OS Install Pre Oracle Oracle Post Oracle

  16. Pre Oracle - Tasks Pre Oracle must: • Configure network: • Configure NICs in server for interaction with Network environment. • Update kernel parameters in /etc/sysctl, for example: • shmmax, shmmin, files-max, etc. • Create Oracle user, group, Oracle directories and permissions. For example: • Users: ias, oracle • Groups: oinstall, dba, ias_admin • Homes: /opt/oracle/home, /home/ias, /u01/oracle • Set parameters in root/oracle user profiles, for example: • ORACLE_HOME, TMP, TMPDIR • Tweak linux configuration, for example: • Remove ldap and ldaps from /etc/services for 9i AS Techniques Kit Pre OS OS Install Pre Oracle Oracle Post Oracle

  17. Pre Oracle - Manual Pre Oracle tasks can be: • Manual • Script-based • Script-based kicked off during OS install ks.cfg %post Techniques Kit Pre OS OS Install Pre Oracle Oracle Post Oracle

  18. Pre Oracle – Script-based Pre Oracle tasks can be: • Manual • Script-based • Script-based kicked off during OS install ks.cfg %post Techniques Kit Pre OS OS Install Pre Oracle Oracle Post Oracle

  20. Oracle Installation - Tasks Oracle Installation must: • Install any pre-Oracle product services: • Oracm, gsd (RAC) • Install Oracle: • RAC, SN DB, 9i AS, Collaboration Suite (Infrastructure, Storage, and Middle tier), 11i, etc. • Apply any patch sets: • Update OUI (if necessary) • Apply patch set(s) • Apply other hot fixes • Validate ORACLE_HOME and other environment variables in Oracle user profile Techniques Kit Pre OS OS Install Pre Oracle Oracle Post Oracle
