Maximum No. of Databases

What is the maximum no. of Database instances that can be created & mounted[opened] at the same time under Windows-NT OS
& under Oracle 8i.

As fas as I know there is no limit for the number of database. However the problem which you may get is the your NT server may become overloaded if you use it with to many databases.

  • Maximum number of database instance on Exadata V2

    Does any body know maximum of database instance can starting on Exadata V2, haft rack configuration. I can start only 13 instance but when start instance 14 it failed. I had try to increased number of semaphore but still not work.

    I would expect that the maximum number of instances would be covered by sanity rather than something Oracle has configured.
    Given that you've not posted the actual error message my recommendation would be that you either provide us with a lot more
    information or that you open an SR with MOS.
    Please also explain how you came to the presumption that the issue was semaphores.

  • Lifetime/Maximum size of Database

    Hi all,
    What is the maximum lifetime of the db?
    What is maximum amount of data can be stored in db?(Is it terabytes)
    Regards,
    Chaitra

    There is no "maximum lifetime" of a database. Nor is there a maximum amount of data that can be stored in a database. The latter depends entirely on how much disk you care to mount. though hardware limitations will always impose practical constraints. Folks are already talking about petabyte sized databases in the relatively near future.

  • What happens when the maximum limit of DataBase partitiong is reached

    Hello,
    We are using SQL server 2012 which allows 15000 partitions per table.
    We are partitioning tables on the primary ID (e.g. periodID) of one of the tables.
    As of now we have data for all the period in the DB. I am wondering that if we reach the maximum partition limit allowed by SQL server then what is the suggested approach?

    Hi Rachana,
    I have not tried it myself so I do not know. I suppose, it would just fail to create new partition. However, I heard some stories about performance issues, mainly related to subotimal execution plan choices in the systems with a few thousands partitions.
    Frankly, I would not be surprised to see such problems. Under the hood, every partition becomes "individual table" with data in clustered and aligned nonclustered indexes sorted on partition scope. In any case, I would consider systems with thousands
    of partitions are the edge cases. You rarely find them in the real life and some inefficiencies and problems could slip through the cracks in the test plans.
    I would also suspect that number of partitions in DW systems is less important than in OLTP due to the query patterns - scans vs. seeks. 
    With all being said, I would consider such designs as impractical. Partitioning is management feature, which helps to address a few challenges, such as improving system availability with piecemeal restore; implementing tiered storage; improve concurrency
    during ETL processes; implementing sliding window scenario; etc. I can see very little benefits of creating large number of partitions. Obviously, in some cases it could be beneficial to have a few dozens of operational (actively accessed and volatile) data
    partitions. However, you rarely have the case to implement large number of partitions on historical/old data. Administrative overhead could easily outweight any benefits here.
    For example, if I needed to architect partitioning on the large OLTP table that stores data for several years, I would partition operational data (weekly, monthly - depends on the requirements); partition previous-year data on quarterly or yearly basis and
    keep older data in the single partition. Tiered storage and availability SLAs would become the most critical factors in the decision.
    In fact, I would consider to combine both, partitioned views and partitioned tables together keeping recent data in the separate tables to improve accuracy of index statistics and old data in partitioned tables using partitioned views on top of that. But
    it is the subject of another discussion. 
    Thank you!

  • Maximum Number of Mirrored Databases Decreases as Number of Available Cores Increases?

    Hi,
    I wonder if you can help me. We're planning a large in-house mirroring deployment and are concerned we may (at some point) run into the limits described in the following KB article:
    http://support.microsoft.com/kb/2001270/en-gb.
    Based on the formulas contained within the above article, I knocked up a quick spreadsheet to see how increasing the number of cores might allow us to increase the number of mirrored databases. However, to my surprise, my calculations imply that as you increase
    the number of cores, the number of databases you can potentially mirror decreases?

    Hi  rushandy,
    As the KB post, we need to calculate the max worker threads, which is default no. of worker thread SQL Server will spawn. about database mirroring requirements for worker threads, we need to calculate the number of threads required per mirrored database.
    At end,
    maximum number of databases that can be mirrored = the max worker threads/ the number of threads required per mirrored database.
    As your post, for 64 bit architectures, if the number of logical CPU cores is 16 on the mirror server, after calculating , maximum number of databases that can be mirrored is 117. However, in actual scenario, the mirroring databases is less than 117, or
    else, it will cause some errors, such as error 17884 and so on.
    Usually, not all worker threads would be available to perform mirroring activities as some threads are assigned to core database activity on the server. For more information, see:http://sqlknowledgeshare.blogspot.com/2012/02/do-you-know-maximum-number-of-databases.html

    Dear All,
    I have a problem regarding maximum number of database connections that can be handled .
    Theoretically i am aware that the number of sessions we set in init ora settings tells me the maximum
    connections that can be opened.but this number will be also be dependent on the capability of the OS to handle the sessions.
    is there any way i can analyse the number of possible connections possible if I have the OS memory and CPU parameters with me

  • How many databases can I create under Hyperion Planning

    Dear all,
    I'm new to Hyperion. I have a doubt on Hyperion planning. In our project we have only one database for every planning application. Can I create multiple databases? If yes, what is the maximum number of databases can I create?
    If this post is not related to this category, please provide me the exact category so that I can post in the exact place.
    Please help me ASAP.
    Thank for all your help in advance.
    Regards,

    Hi,
    You can create five databases in a planning application ( three custom,workforce and capex).

  • SQ01 restricting the number of database accesses

    Hi,
    I created a report using SAP Query (SQ01). When I run the query a dialog box appears asking the maximum number of database accesses.
    The value entered here directly affects the result of the report. The user has to change the value manually in order to see the complete set of results, set it 999999 for example.
    I want to get rid of that dialog box. Is it possible?
    If not can I change the default value '100' to anything I want?
    Thanks...

    That is true, it is a bit loaded report. It includes additional fields, selections and another select statement for each record. I tried to keep it as simple as possible but that is the only way that I could think of.
    The joins are:
    VBAK - VBAP
    VBAP - VBUP
    VBAP - MARD
    VBAP - MARA
    The report basicly brings the stock amounts of open sales order items.  In addition the total consignment level for that item is also requested, so I wrote a select statement   in record processing which finds the total consignment level from the MKOL table for that item. I could not simply add MKOL to my join list because it than divides each item to the number of vendors that exists in the MKOL table. The user is not interested in the amount for each vendor, only the total amount.
    The performance is not that bad, but as I said before the result of the report is different for different limits of database accesses.
    Is there a way to omit the limit?

  • Deleting old data won't reduce Windows Azure SQL Database usage

    My Windows Azure SQL Database usage keeps increasing. Deleting old data didn't help much. I was wondering how to figure out the distribution of the usage. All tables in my DB should not occupy more than 5GB and now it is most 12GB. Please help!
    http://yanflex.com

    Hello,
    The database fee is amortized over the month and charged daily. The daily fee depends on the peak size that each database reached that day and the maximum number of databases you use. So, if the peak size of database is 12 GB  and then you delete data
    to reduce the size, it still charge based on 12GB this day.
    You can use the following statement to get the database size:
    SELECT SUM(reserved_page_count)*8.0/1024 as DBsizeinMB
    FROM sys.dm_db_partition_stats;

  • RE: Number if databases in Directory Server 5.2

    Hi,
    Im looking to find out what the maximum number of databases should be in Directory Server 5.2.
    I know that previously Sun had recommended that a certain number not be exceeded, but Im now looking for figures.
    If there is any other information available, please post it.
    thanks
    ndrb

    Just for the fun of testing, we did create more than 50 databases... The server works ok, but some operations start to be less responsive...
    I would not recommend to use this in real deployments if there is also a lot of entries in the databases.

  • Maximum No. of DBs involved in Oracle Streams

    Hi,
    Is there any limitations in Maximum No. of databases involved in Oracle Streams.
    I have implemented schema level oracle streams between two database. I am planning to extend to another 6 database. Is it feasible or any restriction, pl. clarify.

    I am not aware of any such limitation. Also I cannot find anything in Oracle documentation as well. The only limiting factor in this case would be the availability of resources and the network bandwidth available between these databases.

  • ADF 11g- Selecting Maximum value of a field on Commit Button

    Hi

    return null;
    please do guide. what to do.
    Regards

    Thanks,
    I know, that's why i am try to put this on save button instead on any other.
    But this is not an issue whether to use sequence or max()+1. I can use sequence instead but even then i have to get the nextvalue on form before commit.
    and i have to put that on commit button.
    Commit but try to commit the form before getting anything from DB.
