Database cache (old wine in new bottle???)

Hello!
today to my shock I realised that
the entire Database cache is indeed
based on REPLICATION!
Can someone please confirm to me
(rather allay my fears) regarding
performance, before I go live?
Thanks
Further can someone please answer my
following doubts:
Can icache database be used as a
standby(?) in case the origin database crashes?
My application uses forms/reports/mod_plsql
can I exploit Database cache?
Can I have 2 distinct cache databases
on one node, have 2 distinct origin databases?
Thanks a lot

Replication plus Net8 library little rewriting (little trick :). This library is modified only in iAS distribution. To use this functionality you must set ORA_OCI_CACHE environment variable, but you can not put it in the Registry :)
iCache can be used as a 'standby' without update availability and you MUST connect directly to iCache database.
Yes, you can
You can not have 2 distinct iCache databases on the same node.
You can have 2 distinct origin databases and one iCache on the same node, but iCache can be bound only to one of them.

  • Old wine in new bottle... Linksys Smart Wi-Fi

    Linksys Smart Wi-Fi, wow a new nice feature!
    Or "just" Cisco Connect Cloud?
    Cisco keeps trying to sell us "new" things.
    They better release real new things, like the promissed Classic Firmware upgrade for the "Linksys Smart Wi-Fi" enabled routers.
    We still deal with 2.0.37.131047 while the following issues are fixed in the CCC release:
    - Added support for Class B and C subnets
    - Updated WiFi driver
    - Fixed guest network setup issue when router LAN IP set to 192.168.3.1
    - Fixed some minor issues

    What ever it is, it is close to hot air.
    What the consumers would really appreciate are bug fixes, reliable routers and real enhanced wireless range.
    The current routers do have bugs, due to the bugs they are less reliable and due to the sleek design with the tiny internal antenna's the wireless "g" range is for sure less then a good old WRT54G, giving many people very bad feelings.
    It is cool to release 802.11ac products, it is cooler to make sure you produce real good products and give the best support.
    Why is Linksys able to sell the WRT54G series for over 10 years (it is still sold), simply because it does what the box says and it does it reliable, plain simple. Why do many people buy an "EA" router, because they have the excellent experience of the WRT54G series.

  • Database Cache and Gateways

    We are considering using Oracle Database Cache to speed up a web application that reads data from a mainframe database. Since Database Cache only works with Oracle databases, we plan to create a new Oracle database that acts as a gateway (using ODBC) to the mainframe.
    The question we have is whether this would be possible and would make sense from a performance perspective. It is possible that Database Cache makes clever use of Oracle metadata (table update timestamps, etc) which would not be available for tables linked through ODBC. In this case, Database Cache might not work properly.
    Is it possible to configure Database Cache in such a way that that the application reads data from the mainframe only when the data in the cache is more than an hour old?

    moving up...
    Hi
    I have a question regarding the 9iAS database cache: when I
    select a table to be cached, does the cache also pull up the
    indexes definition from the origin database? Another way to put
    it: if I cache a table which has an index on the PK ( on the
    origin database ), is the index also created on the db cache or
    it performs a full scan for every query?
    Thanks

  • Automatic MOLAP cube : Proactive caching was cancelled because newer data became available

    When I process the cube manually after processing Dimension, It works fine. But when I append data into database column, It performs proactive caching, at that time it fails.
    Sometimes: It does not get key attribute because measure gets processed before dimension
    and sometimes it gives error:  
    Proactive caching was cancelled because newer data became available  Internal error: The operation terminated unsuccessfully. OLE DB error:
    OLE DB or ODBC error: Operation canceled; HY008. Errors in the OLAP storage engine: An error occurred while the dimension, with the ID of 'call dim Monthly 201401 2', Name of 'call dim Monthly
    201401 2' was being processed. Errors in the OLAP storage engine: An error occurred while the 'MSW' attribute of the 'call dim Monthly 201401 2' dimension from the 'callAnalysisProject' database was being processed.  etc....

    I have also seen this error occur in other scenarios.
    In the first if you have set Pro-Active caching to refresh every 1 minute and your query takes 2 minutes to refresh the error above can be displayed.  Solution increase your refresh time or tune your Pro-Active caching query.
    In connection with the above if your server is limited on available resources this can also cause the slower query response times during refresh and the message above.

  • Old Logic + a new Mac = can't open old projects anymore. De/re-install?

    Hi everybody,
    maybe someone can advise me with this problem:
    I bought a new Mac recently, did install a fresh OSX 10.5 and then used migration assistant to transfer my old user account from my old Mac (10.4), incl. all files. It did take a night, but it worked - or so I thought. Actually all applications work as they should, except for Logic. I had to re-authorize a few plug-ins, but then all seemed to be cool. I can open a new project, record audio, midi, add plug-ins, all cool. But I ended up with 3 problems, which are really annoying:
    1) EXS24 couldn't find most of the samples anymore. Most, not all. I have 4 internal HDs, one for the system, one for audio recordings, one for samples, one for "other stuff". 2 of these disks came from the old Mac, 2 new ones, content copied from old Mac. In the EXS prefs I set "search for samples" to "all volumes", but it still didn't work perfectly. Finally I bought EXSManager Pro and now it seems to work again. I didn't try ALL samples yet, but the +/- 20 EXS instruments I tried, did load all samples.
    2) Space Designer doesn't load impulse responses for the presets anymore. They're there and at the right place. I can load SD and import an existing impulse file, no problem. But the presets don't find the required files anymore.
    3) Now - and this is the worst one - I can't open old projects anymore. I just can't. It starts loading, I see the rainbow thing (don't know the right word), it turns black & white and that's it. You can watch this forever and nothing happens.
    Regarding all 3 issues:
    I don't get any error messages. Logic doesn't crash, I can't click 'apple-.' to stop loading/searching. It just doesn't open the file. I had a coffee, a pizza, I let it try for 2 hrs+, but neither did it load a SD preset or an old song file. All I can do is manually quit Logic.
    But when I open Logic with the CTRL-button down and click "no" to core audio I can open all songs. Of course I can not hear a tone then, but it's all there. Opening a song takes 3 secs then. I tried to safe a song then with a different name, re-started Logic with core audio but same result. It get's "stuck".
    Of course I checked user permissions and all the usual trouble shooting clicks, but still Logic has a mind of it's own. I installed a 2nd user with admin rights, though still the same, plus all the 3rd party plug-ins refusing to work.
    Now I was thinking, should I de-install Logic and re-install from the original CDs maybe. And if so, is there anything special I have to take care of? Like manually removing any prefs or cache files?
    Or completely re-install the whole Mac? (pleeease no....)...
    If anybody has any idea, it'd be highly appreciated.
    Thank you in advance and for the energy to read my little novel here,
    cheers,
    Joern

    Ok, either my question was too long or nobody seems to have an answer. Sad, either way
    Here's something I found out in the meantime, maybe this is interesting for somebody or maybe - problem's not totally solved - enough info for any of you to give me further advice.
    When I start Logic Core Audio driver de-activated, I can open old songs. Then I save them in a new folder with all audio files and a new name. And I remove all EXS24 instruments as well as the Space Designer. I quit Logic, re-open with Core Audio activated and I can open the song.
    Problem no.1: EXS24 instruments don't find the appropriate samples, but EXSMananger Pro did help me with this. Same problem with Space Designer, which doesn't find the impulse responses, connected to a certain preset.
    Two questions, every idea would be great!
    - Is there any way to teach Space Designer Presets where to look for impulse respones. I can load IR samples directly and create a new preset, but I can't use my old ones.
    - Is it possible to install Logic from scratch over an existing version? Or how should I de-install everything connected with Logic and then install a fresh version from CD?
    Thank you again,
    Joern

  • Oracle 10g RAC Database Migration from SAN to New SAN.

    Hi All,
    Our client has implemented a Two Node Oracle 10g R2 RAC on HP-UX v2. The Database is on ASM and on HP EVA 4000 SAN. The database size in around 1.2 TB.
    Now the requirement is to migrate the Database and Clusterware files to a New SAN (EVA 6400).
    SAN to SAN migration can't be done as the customer didn't get license for such storage migration.
    My immediate suggestion was to connect the New SAN and present the LUNs and add the Disks from New SAN and wait for rebalance to complete. Then drop the Old Disks which are on Old SAN. Exact Steps To Migrate ASM Diskgroups To Another SAN Without Downtime. (Doc ID 837308.1).
    Clients wants us to suggest alternate solutions as they are worried that presenting LUNs from Old SAN and New SAN at the same time may give some issues and also if re-balance fails then it may affect the database. Also they are not able to estimate the time to re-balance a 1.2 TB database across Disks from 2 different SAN. Downtime window is ony 48 hours.
    One wild suggestion was to:
    1. Connect the New SAN.
    2. Create New Diskgroups on New SAN from Oracle RAC env.
    3. Backup the Production database and restore on the same Oracle RAC servers but on New Diskgroups.
    4. Start the database from new Diskgroup location by updating the spfile/pfile
    5. Make sure everything is fine then drop the current Diskgroups from Old SAN.
    Will the above idea work in Production env? I think there is a lot of risks in doing the above.
    Customer does not have Oracle RAC on Test env so there isn't any chance of trying out any method.
    Any suggestion is appreciated.

    If your customer is not entrusting on ASM. So Oracle Support can answer all doubt.
    Any concern .. Contat Oracle Support to guide you in the best way to perform this work.

    ASM Supports many Terabytes, if you need to migrate 3 Database with 20TB each using this way described above would be very laborious .. .. So add and remove Luns online is one feature that must work.
    Take the approval from Oracle support and do this work using the ASM Rebalance.

  • How to copy all the data from old computer to new computer (server)

    Dear all,
    As I want to upgrade the server from old computer to a new one.
    I want to ask how and easy way to copy all of table, sequence, ......data from existing old computer to new computer.
    The old server is window 2000 Server with oracle 10g
    The new server may window 2003 Server with oracle 10g
    Thanks a lot
    Francis SZE

    As far as I can see you are copying from db10g for windows to another host on the same platform and same OS, so a simple cold backup taken from the source database can be restored at the target host. You must first make sure the configuration files and service be created prior to performing the database startup procedure at the target host. You may also as suggested, perform an rman duplication task

  • Data import from old system to new system, key by raw16 column

    hi, experts,
    now, I have a new system, the system design is to use raw(16) column as key column in all database tables.
    of course, when new system goes live (in production), all new transaction records are written to new system database.
    when the new system inserts new records, it handles itself to avoid conflicts by value of the raw(16) key column
    I now face this issue:
    I need to import data from old system to new system, I use sys_guid() to fill up the raw(16) column in new system database.
    how can I avoid the conflict from value of raw(16) column between old system data and new system database data?
    the sql I write is very simple:
    insert into new_sys_table_a (key_column_raw_16, ..., ... )
    select sys_guid(), old_sys_col_a, old_sys_col_b
    from old_sys_table_a;

  • Need help transferring itunes library from old computer to new laptop

    Hello,
    I recently purchased a new laptop and am having trouble getting my library to transfer to my new laptop, i followed this step by step process http://support.apple.com/kb/HT1329?viewlocale=en_US and in the end ended up with no music on my ipod and no music in the itunes library on my new computer...
    So then i went into Itunes on the new computer and clicked import library under File, so i found the Music folder that i had transferred over and it imported the music but all my playlist were not there, just songs. So i ended up syncing my ipod back to my old computer so i would get all the songs and playlist back on as it was originally before this whole process...
    My desktop runs XP while my new laptop runs Vista Ultimate w/ SP1 home edition, dont know if this matters...
    So not sure where i should go from here, i have already Authorized my laptop with the itunes store , i was thinking of uninstalling Itunes on my laptop and starting over from scratch, will this help?
    BTW when i did the original transfer i used my Ipod as the hard drive as it had plenty of storage room left on it, i do have access to a 250GB external HD i was thinking of using that and trying that to transfer the library...
    So if anyone can tell me how to transfer my Itunes library from old comp to new laptop it would be greatly appreciated...

    The method you used should work if followed exactly.
    The key points are - is your music all together? It must all be in the iTunes Music folder in the iTunes folder.
    When you copy the iTunes folder to the iPod you get the library database with your playlists and the iTunes Music folder containing the music files.
    Since you had trouble doing this with the iPod, why not try copying your iTunes folder to the external drive.
    The method is identical the one for the iPod except you leave out the iPod specific stuff.
    You install iTunes on the new PC, then you drag the newly created iTunes folder out the Music folder to the desktop, then you copy the iTunes folder from the EHD into Music, replacing the one you dragged out.
    When you have done that, you need to check that your account has full control of your iTunes folder - Vista is fussy about that - you will not be able to edit track info if you don't have full control.
    Vista file folder permissions help

  • SQL Result Cache  vs In-Memory Database Cache

    Hi,
    can anyone help me to understand the relations and differences between the 11 g new features of SQL Result Cache vs In-Memory Database Cache ?
    Thanks

    I highly recommend you read the 11g New Features Guide. Here is a sample from it:
    h4. 1.11.2.9 Query Result Cache
    A separate shared memory pool is now used for storing and retrieving
    cached results. Query retrieval from the query result cache is faster
    than rerunning the query. Frequently executed queries will see
    performance improvements when using the query result cache.
    The new query result cache enables explicit caching of results in
    database memory. Subsequent queries using the cached results will
    experience significant performance improvements.

    Hi,
    For custom forms and reports, you need to open it using Forms/Reports Builder 10g, compile it, and upload it again to the server.
    For the CUSTOM_TOPs, make sure it is set in the custom<CONTEXT_NAME>.sh file under $APPL_TOP, and in default.env file on the Applications tier.

  • Database cache settings for 4.13 on NT 4

    The database cache settings and the documentation have always been
    confusing.
    I have about 35000 entries in my directory. If I have enough available ram
    should I try to put all the entries into ram? The default setting is a 1000,
    should I change it to 35000? Will I notice any great speed increases.
    And the second setting has to do with index cache. Should I try to get that
    into ram also? My id2entry.db2 file is about 40MBs. Should I change the
    default from 10MBs to 40MBs? Will there be a significant increase in speed?
    Thanks.

    Thanks Russ H for your quick reply.  I am still fairly new to FCP X coming from using FCE not iMovie.
    The project I'm working on I had already started before posting yesterday.  Is it possible to change the settings for what I have already done, or no I need to start all over again?
    Thanks again
