[Methods] neighborhoods installing Oracle RAC, OCFS, RAW Device, OSD of the differences? I now environment as follows : Taiwan : HP DL140 2 + hardware RAID Software : Windows 2000 Server, Oracle 9i R1 We need now to RAC, data, we saw some OCFS said in some OSD, some naked equipment I do feel very confused Several methods are not able to achieve this, there is the difference between them? No one can be achieved with the installation process, I would like to thank the BTW : Forum search function how impossible, I first have to import user names and passwords, user names and passwords for being given the wrong that is not my score low enough authority? OCFS or RAW Device for use, experts they have any suggestions? Common is a raw and ocfs ocfs is provided by the Oracle Cluster File System, operates on the Linux and Windows platforms, the advantage of management more convenient and can be used as data files, control document, document archiving is so raw Bethlehem district, the advantage of relatively mature technologies. Management shortcomings is not particularly convenient. If the production system, the proposed landlord do use raw data files, log file ocfs do list if tests of the system, using the most simple ocfs. 10g can use asm, and the function can almost ocfs, it is also a good choice Thank blue_stone Read a few articles that you made, a great deal, after a lot of help requested Naked use zoning, table space is allocated to each district a logical? I am new to the table space how do? There should be regional? CREAT TABLESPACE words, how dbf文件 the designated route? If I built two databases, such as SYSTEM plots Table space is not, there will be confusion? More questions, the audience this way! Top about themselves, seek help-ing "Naked use zoning, table space is allocated to each district a logical? Each table is not a logical space allocation district, but also each of a nude equipment corresponding data files, each describing a logically district counterparts equipment, each room table one or more logical district counterparts, in 1987 a table contains one or more logical space district "I am new to the table space how do? There should be regional? Of course, the need to create space for new forms of nude equipment is not used (district), if there are no hard disk using the naked equipment (district), it can be used by the district, if not the, the need to re-establish. So, if the use of nude equipment, it is best to start planning for a good disk, in addition to the area, the other to create some surplus district, can be used when the need arises. This is the bare equipment is not flexible "CREAT TABLESPACE words, how dbf文件 the designated route? And the use of existing space in the paper to create forms using the same language, for example, CREATE TABLESPACE "TOOLS" LOGGING DATAFILE '/dev/rhr_tools_512m' SIZE 10M REUSE; "If I built two databases, such as SYSTEM plots Table space is not, there will be confusion? The establishment of the two machines and a database in one word, in the database environment variables specified when the nude DBCA_RAW_CONFIG equipment and the corresponding table space, the creation of the database configuration file can be designated a different DBCA_RAW_CONFIG. Like to see where, because of improvements in technology and hard disk OS improvements raw disk file and the files have been managed OS is not much distinction. But there are many restrictions when backup raw datafiles. I would use OS managed datafile.s John Blue_stone really is as sobering words, I have to answer the long-standing problem of confusion Ultimately, each logical area designated by the Symbolic Link Manager Name the only Link, a database linking documents and logic pm , But also the distinction between the different names of the same database table space documents BTW : I deeply feel : RAC itself is not very difficult, but only to see some English Document, really bogged down : First English is limited, and may not understand the precise; 2 No clear description file itself. If people have done a guide, then they will quickly understand. Thank you very much help [ Closed window ]
