CHAPTER 13 MIGRATING TO EXADATA• net.core.wmem_default = 262144• net.core.rmem_max = 4194304• net.core.wmem_max = 2097152• net.ipv4.ip_local_port_range = 9000 65500So how does it work? Basically, once all platform hardware and software requirements are met, thefollowing steps allow your current production system to join the Exadata storage network and gainaccess to the storage cells:1. A familiar pre-migration task is to configure the init.ora, password and oratabfiles on Exadata to allow you to start up your database on Exadata.2. Configure the IB network device, giving it an IP address on the Exadata storagenetwork.3. Create the cellinit.ora file with one line containing the IP address andnetwork mask for server on the storage network:> cat /etc/oracle/cell/network-config/cellinit.oraipaddress1=192.168.12.10/244. Create a cellip.ora file containing the addresses for each of the storage cells:> cat cellip.oracell="192.168.12.3"cell="192.168.12.4"cell="192.168.12.5"5. Bring the InfiniBand device online:ifconfig ib0 upib 0 Link encap:InfiniBand HWaddr80:00:00:48:FE:80:00:00:00:00:00:00:00:00:00:00:00:00:00:00inet addr:192.168.12.10 Bcast:192.168.12.255 Mask:255.255.255.0inet6 addr: fe80::221:2800:13e:eb47/64 Scope:Link6. At this point if everything is working you should be able to see the Exadatadisks by running the command from the oracle user account: kfod disk=all[enkdb01:oracle:EXDB1] /home/oracle> kfod disk=all[enkdb01:oracle:EXDB1] /home/oracle> kfod disk=all--------------------------------------------------------------------------------Disk Size Path User Group================================================================================1: 1313600 Mb o/192.168.12.3/DATA_CD_00_cell01 29: 93456 Mb o/192.168.12.3/RECO_CD_00_cell01 41: 469136 Mb o/192.168.12.3/STAGE_CD_00_cell01 461
