About this guide
1 Overview of Data Integrity Check Function overview Data Integrity Check insures validity and protects Oracle data stored on the array. Data Integrity Check has the following two purposes (see Figure 1): • Preventing invalid data from being written to the array When data is stored on the disk array, the data is transferred through many paths and can become invalid. Data Integrity Check ensures that the Oracle data is valid before it is written to the disk array.
Figure 2 Data Integrity Check components Data Integrity Check and RAID Manager Data Integrity Check is configured and operated using Data Integrity Check commands in RAID Manager XP. For RAID Manager operations, refer to the HP StorageWorks RAID Manager XP User's Guide. You must specify the volume to be checked, and the type of check using RAID Manager (the types are different depending on versions). The files (constructed in RAW volume) that are checked are: Data, Redo log and Control.
2 Data Integrity Check operating environments and prerequisites Data Integrity Check requires the following: • A Command View XP array (see Requirements for the array) • A Host server that supports an Oracle database and has RAID Manager installed (see Requirements for the Host Server) • An Oracle-data validation service (see Restrictions and Conventions ) Requirements for the array Data Integrity Check requires a properly configured array and a channel adapter with the correct microcode.
• Sun® Solaris™ 8 or better. For further information on the Solaris™ platform, refer to the HP StorageWorks XP Remote Web Console user guide for XP12000/XP10000 • HP-UX 11.0 or better. For further information on the HP-UX platform, refer to the HP StorageWorks XP Remote Web Console user guide for XP12000/XP10000 • Windows 2000 Advanced Server (Service Pack 3 or later) • AIX 5L Version 5.1 ML3 Oracle database One of the following Oracle databases is required.
For host servers: • Do not write data other than Oracle data to the Oracle data check volume (LU). If multiple paths are set to the same volume (LU), check if those paths are not all set as the target of Oracle data check. • Do not set the data storage location of the Data or Control file and the Redo log file to the same volume (LU). • Do not store Oracle data of different block sizes in a volume (LU). Only write data of the same block size to a volume (LU).
