• Does the log_file_name_convert parameter only rename the redo log files in a dataguard?

    Hello I've installed a Oracle RAC 10gR2 with two nodes and using the dataguard in a single database. I'm using a different SAN to both environments (all the servers are linux). I'm using the physical mode for replications and using the OMF (I'm using the ASM to handle the storage with the OMF...

  • Replicating SAN to DR Site

    We are looking to build a warm DR site across town. How are other companies managing to duplicate their data in a reasonable time to another location? We are looking to copy around 150 GB per day. We don't need up to the minute data, up to the hour or two is acceptable.

  • iSCSI SAN Server suggestions?

    We are in the process of purchasing a new SAN server. I was curious if anyone has any good or bad experience with HP, Netapp, Dell, Fujitsu or others. We will be using Exchange 2007 mostly in the environment and need something that is very expandable. Thanks

  • Accessing heterogeneous disk arrays to a Windows server using a single HBA via SAN

    I am planning my disk array upgrade, and I want to know if anyone has any thoughts, or if there are any reference/best practice/white papers, for accessing heterogeneous disk arrays to a Windows server using a single HBA via SAN. Any concern about the multi-path software?

    My current employer began allocating disk before having a storage administrator on staff.
