Oracle Backup End to End Automation with BRBACKUP and RMAN

Hi,
We are about to implement a Oracle on mySAP 2004 or 2004 i.e. either NW2004 or NW2004s. Currently we are on DB2 UDB.
We are going to use legato for backup.
legato networker module (I guess this is module built for BACKINT)  for SAP is too costly, so we are looking at alternatives for backup using legato without using networker module.
We have virtual tape library (disk that emulates as tape library). we plan to keep 30 days/versions of backup there.
Can we use BRBACKUP and RMAN to achieve end to end backup automation without using networker module by using the BRBACKUP delivered options and integrating to RMAN.
I do see BRBACKUP options like tape_box and pipe_box. Are these will be useful to achieve this.
Other question is do we really need to integrate with RMAN. What are the advantages.
So far I see the advantages with RMAN are 1. incremental backups. 2. Online backups are handled more consistently than normal.
Appreciate your information.
Thank you,
Ravi Gandavarapu.

Hi Jason,
Yes, we have SAN storage. Also thinking to use split-mirror for production.
Do this need legato networker module. Or we can put a script without out the module also?
>>There is one little complexity to this but if you're interested I'll explain it. <<
Would you please explain what it is ?
Again for my dev and qa systems we are not planning split-mirror.
My plan is to back them up straight to VTL (disk based). Do you think using RMAN here helps (because of incremental) ?
I was recently going through 10g features. Looks like 10g has a feature that you can merge incremental with level0. Does brbackup supports this?
Appreciate your info.

  • Migrating Non ASM, Non RMAN to New Server with ASM and RMAN - Possible?

    We currently have a database ( Oracle 10g R1 ) on a Sun Solaris server that is NOT using ASM or RMAN. The database is about 300GB. We are getting a new server and we want to install Oracle 10g R2 with ASM and RMAN and migrate the database.
    I have seen the documentation on migrating non ASM to an ASM server but the methods all use RMAN. Is it possible to migrate to an ASM database without using RMAN? Would datapump import/export work if I created a new database on the new server with all the same tablespaces? Or, do I have to bite the bullet, install RMAN on the old server and do the backup?
    Thanks.

    If you're not using RMAN that doesn't mean you can't use it to perform a single backup, rman is contained in every oracle RDBMS installation version 10G or higher.
    this is only a sample of how to do it
    RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '<file_system_path>/%U.DBF';
    --first we allocate the channel default channel.
    RMAN>RUN
    ALLOCATE CHANNEL DEFAULTCHANNEL TYPE DISK;
    SHUTDOWN IMMEDIATE;
    STARTUP MOUNT;
    BACKUP DATABASE;
    SHUTDOWN
    }then once you have it, you can do what you want.
    It should also be possible to manually restore the database from the original datafiles but it's better to follow the solution involving RMAN.

  • HT1178 Can you backup to same time Capsule with PC and Mac

    How do I backup to same Time Capsule with both PC and Mac

    - backup iMac to TC and hook up HD to USB port on TC to backup PC laptop
    Hmmm not better IMHO.. as long as you disk image the TC.. and the amount of space you have far exceeds total usage on both computers.. For the TM backup on the Mac you want TC area to be at least 3x the used space on the drive.. leaving out VM or bootcamp partitions if you use them.
    Plus enough space to back up the PC laptop a couple of times over.
    USB hard drive is fairly slow.. but should be ok for backup over wireless.. just be aware you cannot unplug the USB drive and use it direct unless you format it FAT32 which is very poor format. So first backup is going to be slow.
    - backup iMac directly to HD thru firewire and backup PC to HD hooked up to Airport Extreme
    If you don't already have a TC then this is fine. Firewire local disk is much faster than network backup even over gigabit.
    Any of your options would work ok.. doing disk image on the TC is most difficult to get working and limits the hard disk space. Balance out what you already own network wise with what you need.. there are plenty of routers now with USB ports that will deal directly with windows using NTFS.. if you end up using firewire local disk to the imac..

  • Problems with SIMPANA and RMAN

    Sorry originally posted in Database General (mea culpa)
    We purchased Dell Comm Vault wth Simpana MML. We have been fighting with it trying to get it installed for a couple of months. We finally got a Simpana engineer on site and we are actually able to run sbttest successfully, but when we try to use the libobk.so to make an RMAN backup to CV disk, it fails.
    We have spent hours and hours on this (probably in the weeks now) wasted trying to get it working. We are 'supposed' to move our production to our new OEL/RAC environment in @ 3 weeks, BUT if we don't have backups running we miss that date.
    Anyone out there using Simpana? If so, did you have problems getting it working and WHAT was the magic bullet to make it work.
    Thanks

    Already answered in the other thread ... this is not an Oracle issue and inappropriate in these forums. Please change the subject of both threads to "Please Ignore" and take this up with Dell and your own management.
    Thank you.

  • NOLOGGING with CTAS and RMAN's Incremental backup

    DB Version: 10.2.0.4
    OS : AIX
    We use RMAN for our backup scheduled via cron.
    Retention Policy : REDUNDANCY 1
    Type             : Incremental On 31st of every month, in most of our schemas, we recreate lots of tables using CTAS.
    Because of the size , CREATE TABLE statements take a long time. Since we run on Standard edition, we can't use PARALLELISM.
    NOLOGGING is the only option to improve the performance. But we are worried about the redo not being generated for these tables and the potential loss of data in case of a crash.
    Currently we take a LEVEL0 backup every wednesday and Sunday nights and LEVEL1 backup on the rest of the days.
    I know that everything will be backed up on LEVEL0. But, what if 31st falls on a day where only LEVEL1 backup occurs. We'll only be safe until the next LEVEL0 comes along.
    Any workarounds for this?

    When you write "we need" you make an assumption not supported by the facts.
    The fact is that you need to refresh the data ... you do not need to recreate the table.
    This is just one better solution:
    http://www.morganslibrary.org/reference/materialized_views.html
    there are others too. But not knowing your version number, and you still have not really stated the business case, I can not advise which would be the best. But it is safe to say there is no way on earth I would do what you are doing based on what you've posted. For example why at the end of each day can't you copy that day's rows to a predefined table spreading the load out over all 30 days and then, at month's end truncate the current table and rename it then rename the already loaded staging table. The swap could be done in a few seconds with essentially no overhead.

  • Oracle 10g - Cross-Platform Transportable Database (with or without RMAN?)

    Hello guys,
    i am currently on a project for migrating oracle databases from one platform to another platform (both platforms are on the same endianess):
    -> From Linux 64-Bit to Windows 64-Bit
    -> From HP-UX 64-Bit to AIX 64-Bit
    All databases are on Oracle 10g (10.2.0.4) and i have tested two different ways:
    1) The "official" way with RMAN CONVERT DATABASE
    http://youngcow.net/doc/oracle10g/backup.102/b14191/dbxptrn002.htm#CHDEEEAG
    2) "Copy & Paste"
    - Copy & Paste of the database files
    - Recreate controlfile manually on target platform (with help of "backup controlfile to trace" on source platform)
    Both ways are working well and the migrated test databases are running fine.
    Now i am wondering why there is a "RMAN CONVERT DATABASE" command, if it possible to copy and paste the data files and perform two steps manually afterwards.
    The "RMAN CONVERT DATABASE" is time consuming and you still need to copy the RMAN output files to the target platform.
    Is there any special reason, why you need the "RMAN CONVERT DATABASE"? Does the "RMAN CONVERT DATABASE" change some things in the database files internally?
    Thanks and Regards

    Hello,
    Anurag Tibrewal wrote:
    If the source platform and the target platform are of different endianness, then an additional step must be done on either the source or target platform to convert the tablespace being transported to the target format. Of course .. in this case you can not use the "Cross-Platform Transportable Database" - you have to use the "Cross-Platform Tranportable Tablespace" (with RMAN CONVERT DATAFILE or TABLESPACE).
    Anurag Tibrewal wrote:
    If they are of the same endianness, then no conversion is necessary and tablespaces can be transported as if they were on the same platform.Yes, but oracle provides this with RMAN and the command "RMAN CONVERT DATABASE" .. as i already wrote i have already performed the two ways "RMAN CONVERT DATABASE" and "just copy & paste" and both are working fine.
    So my question is if there is any special case in which you should use the RMAN way with "RMAN CONVERT DATABASE" instead of just "copy & paste" if you stay on the same endianness?
    Thanks and Regards

  • Automation with logic and kontakt3

    what is the secret to having individaul track automation using kontakt3

    No secret - either automate the Aux tracks assigned to multiple outs of Kontakt
    or
    use the assignable automation parameters in Kontakt (in the Auto menue at the upper left) by dragging e.g. #001 to any knob of the instrument you want to control-in the track header select #001 and write your nodes with a controller or with your mouse. I´ll post a picture if you need more help.

  • Hibernate OR EclipseLink...Which is best with Weblogic and Oracle DB?

    Hi All,
    In my company, we are using Oracle DB and Weblogic application server. So in the process to upgrade or switch to new ORM, we shortlisted two options - Hibernate and EclipseLink.
    I gathered following summary regarding both ORMs -
    Hibernate:
    1.     When you need to train people, like we are going to do next week – most of the companies have Hibernate experts.
    2.     When you hire new developers, most of them come with specific Hibernate experience.
    3.     When you need to consult with experts, both in the internet or consultants, you have LOTS of options. Endless forums and communities all regarding Hibernate.
    4.     Hibernate is an open source which has a huge community. This means that it will be improved all the time and will push the ORM market forward.
    5.     Hibernate is an open source which means you have the code to handle, and in case needed, fit it to your needs.
    6.     There are lots of plugins to Hibernate, such as validations tool, audit tools, etc. These becomes standard as well and dismiss you from impl. things yourself.
    7.     One most important thing with ORM tool, is to configure it according to your application’s needs. Usually the default setting doesn’t fit to your needs.
    For that sake, when the market has a huge experience with the tool’s configuration, and lots of experts (see point 1 and 3) – most of chances you will find similar cases and
    lots of knowledge about how to configure the tool and thus – your application.
    EclipseLink:
    1. Fully supported by Oracle. Hibernate no. In case of pb, it could be cumbersome to prove that it is a pure Weblogic one. Concretely, we will have to prove it (waste of time and complexity).
    2. Eclipse link is developed by Oracle and the preferred ORM in the Weblogic /Oracle DB world.
    3. Even if at a certain time EclipseLink was a bit late compared to Hibernate (feature), EclipseLink evolved very fast and we can consider now that they close the gap.
    4. No additional fee as soon as you have Weblogic license. You will need to pays additional fee if you want some professional support on Hibernate.
    5. We are currently relying on Hibernate for our legacy offer and are facing pb in second level cache (JGroups). Today, we are riding off this part!. Consequences are limitation in clustering approach (perf)
    6. On EclipseLink side we do succeed to manage first and second level cache in a clustering approach.
    7. Indeed Hibernate is open source, so you can imagine handling it. In reality, the code is so complex that it is nearly impossible to modify it. Moreover as it is LGPL, you need to feedback all the modified sources to the community systematically.
    8. All tests performed by Oracle concerning Weblogic are using EclipseLink. Moreover, Oracle says that some specific optimizations are done to manage Oracle DB.
    9. Hibernate comes from JBoss community.
    Right now we are preferring Hibernate but there are concerns/reasons like EclipseLink developed by Oracle and preferred ORM in Webogic/ Oracle DB world (compatibility of ORM with DB and App. server), support comparison with both ORM, which are preventing to finalize the decision.
    Please help me with you views and opinions and share you experience with us so that we can make a perfect decision.
    If you want you can also reply to me @ [email protected].
    Thanks.

    The way the ORMs are designed, integration with application servers are relatively simple, and all provides the same features. Also since WebLogic have been around for a while, all ORMs are all well tested in this configuration.
    Hibernate has lot more users, and is likely very often used with Oracle DB, so you can expect not much bug against Oracle DB, maybe even less bug than EclipseLink, which is not much used. EclipseLink does provide support for some esoteric Oracle DB features like hierarchical and flashback queries.
    OpenJPA and DataNucleus are also JPA compliant. It’s likely that Open JPA has a higher user base than EclipseLink, so less unknown bugs.
    Oracle paying support is well known to be a bad joke. It’s a negative return to use this channel, even if they would be free. So in reality, you end up to use the open (free) forum to get support.
    What’s was lacking with Hibernate before is Dynamic Fetch Planning, but they now have some support, see http://opensource.atlassian.com/projects/hibernate/browse/HHH-3414. OpenJPA was the first to implement this must have.
    EclipseLink has query in memory, which can be used, but the API do not help to leverage it, and EclipseLink’s leadership made it clear that they are not going to make it better, instead they want to push Coherence cache.
    Hibernate has an open API for second level cache, which mean you can get out of problem by using another implementation, for example, EHCache seems to be professionally tested, so I would be surprise you find obvious bugs.
    I cannot comment on Hibernate source code quality, but I can tell you that locking mechanism in EclipseLink is used to be very fragile, and many concepts are dispersed over the code base.
    The runtime monitoring of Hibernate have always been great due to the fact that JBoss have always been strong on JMX, EclipseLink has not much usable features on this.
    If I would be you, I would consider OpenJPA or Hibernate instead of EclipseLink, the main reason is that because EclipseLink has a so low user base, I have found lot of obvious bugs in production, like if I was the only user of it. Then, when I submitted bugs to the small development team, which do not encourage user base contribution, they were too busy trying to keep up adding the JPA interfaces on top of their existing proprietary APIs.

    Hey there 79usma79!
    I have a couple of articles for you that can help you troubleshoot the issues you are seeing with iTunes on Windows XP. The first is a general troubleshooting article, which can be found right here:
    iTunes for Windows XP: Troubleshooting unexpected quits, freezes, or launch issues
    http://support.apple.com/kb/TS1421
    This article can help you find out if there are any conflicts between your copy of Windows XP and iTunes, and can tell you what to do if there are. Before going down the troubleshooting route though, you should take a look at this article, which can help you back up your entire iTunes library to an external hard drive, so if this issue is recurring, you will be able to restore from that backup and will not have to worry about losing your playlists or music again:
