Message-ID: MIME-Version: 1.0 Content-Type: text/plain Title: RE: High-availability database question !!!! Check into the HP "metro cluster". RAC would provide the multiple Node environment; but one would think that a continuous availability scenario would indicate the need for the database to be "redundant" on another system. The HP Metro Cluster may be able to address the database(disk) redundancy.  And depending on the application, volume of data and transaction rate - the 2 way replication gig may be a possible solution. Not necessarily the desired solution; but a possible solution. In addition to the 24x7 that you mention; is there any activity around the other components of the environment for example, load balancing? The web servers? Application servers?   One can create a 7x24 environment; but will a service degradation be acceptable? Just some thoughts........

Hi, When you say maintenance does it includes Oracle patches application? If not, consider Oracle 9i RAC with Dataguard. José Ruivo -----Original Message----- Sent: quarta-feira, 25 de Junho de 2003 11:00 To: Multiple recipients of list ORACLE-L Goodday all We have cutomer who is having a database which should be available 24x7. Now we can't get even a maintenance time to do the database. We tried on several occasion but nothing happens. Now they want us to provide them with a solution to be able to work on "another database" if we need to do maintenance. Could you guys come up with some ideas what we can offer them. Is there any other alternatives besides replication and standby database. Currently the system is running as a package in a cluster environment, HP-UX, so when we go replication route possibilities are that we might have to forget about high-availabilty cluster environment due to things like disk space and memory for switching over during failure. Neither do the standby database a good option in a situation where you'll needing a longer downtime. Please help.
