  • Unable to Create Fact and Dimension tables from the Tools menu in EIS conso

    Hi All,
    In the EIS console, I am unable to create the fact table and the dimension tables to produce my OLAP model from the TOOLS menu whereas I am able to create them by dragging from the left panel where the tables are displayed. I am geeting the below error message:
    "An exception occured while retrieving OLAP model metadata. Please verify you are connected to the catalog and try again"
    Any help appreciated.

    You still haven't told anyone what products besides Essbase you are using, without which this is an impossible question to answer.

    Are you connecting to these tables from Essbase with a load rule / ODBC?  Using Studio?  Using Integration Services?  Any Drill-Through reporting set up?
    This may sound harsh, but if you truly don't know how to answer any of these questions you should probably not be anywhere near this task...

  • Fact and dimension table partition

    My team is implementing new data-warehouse. I would like to know that when  should we plan to do partition of fact and dimension table, before data comes in or after?

    Hi,
    It is recommended to partition Fact table (Where we will have huge data). Automate the partition so that each day it will create a new partition to hold latest data (Split the previous partition into 2). Best practice is to create partition on transaction
    timestamps so load the incremental data into a empty table called (Table_IN) and then Switch that data into main table (Table). Make sure your tables (Table and Table_IN) should be on one file group.
    Refer below content for detailed info
    Designing and Administrating Partitions in SQL Server 2012
    A popular method of better managing large and active tables and indexes is the use of partitioning. Partitioning is a feature for segregating I/O workload within
    SQL Server database so that I/O can be better balanced against available I/O subsystems while providing better user response time, lower I/O latency, and faster backups and recovery. By partitioning tables and indexes across multiple filegroups, data retrieval
    and management is much quicker because only subsets of the data are used, meanwhile ensuring that the integrity of the database as a whole remains intact.
    Tip
    Partitioning is typically used for administrative or certain I/O performance scenarios. However, partitioning can also speed up some queries by enabling
    lock escalation to a single partition, rather than to an entire table. You must allow lock escalation to move up to the partition level by setting it with either the Lock Escalation option of Database Options page in SSMS or by using the LOCK_ESCALATION option
    of the ALTER TABLE statement.
    After a table or index is partitioned, data is stored horizontally across multiple filegroups, so groups of data are mapped to individual partitions. Typical
    scenarios for partitioning include large tables that become very difficult to manage, tables that are suffering performance degradation because of excessive I/O or blocking locks, table-centric maintenance processes that exceed the available time for maintenance,
    and moving historical data from the active portion of a table to a partition with less activity.
    Partitioning tables and indexes warrants a bit of planning before putting them into production. The usual approach to partitioning a table or index follows these
    steps:
    1. Create
    the filegroup(s) and file(s) used to hold the partitions defined by the partitioning scheme.
    2. Create
    a partition function to map the rows of the table or index to specific partitions based on the values in a specified column. A very common partitioning function is based on the creation date of the record.
    3. Create
    a partitioning scheme to map the partitions of the partitioned table to the specified filegroup(s) and, thereby, to specific locations on the Windows file system.
    4. Create
    the table or index (or ALTER an existing table or index) by specifying the partition scheme as the storage location for the partitioned object.
    Although Transact-SQL commands are available to perform every step described earlier, the Create Partition Wizard makes the entire process quick and easy through
    an intuitive point-and-click interface. The next section provides an overview of using the Create Partition Wizard in SQL Server 2012, and an example later in this section shows the Transact-SQL commands.
    Leveraging the Create Partition Wizard to Create Table and Index Partitions
    The Create Partition Wizard can be used to divide data in large tables across multiple filegroups to increase performance and can be invoked by right-clicking
    any table or index, selecting Storage, and then selecting Create Partition. The first step is to identify which columns to partition by reviewing all the columns available in the Available Partitioning Columns section located on the Select a Partitioning Column
    dialog box, as displayed in Figure 3.13. This screen also includes additional options such as the following:
    Figure 3.13. Selecting a partitioning column.
    The next screen is called Select a Partition Function. This page is used for specifying the partition function where the data will be partitioned. The options
    include using an existing partition or creating a new partition. The subsequent page is called New Partition Scheme. Here a DBA will conduct a mapping of the rows selected of tables being partitioned to a desired filegroup. Either a new partition scheme should
    be used or a new one needs to be created. The final screen is used for doing the actual mapping. On the Map Partitions page, specify the partitions to be used for each partition and then enter a range for the values of the partitions. The
    ranges and settings on the grid include the following:
    Note
    By opening the Set Boundary Values dialog box, a DBA can set boundary values based on dates (for example, partition everything in a column after a specific
    date). The data types are based on dates.
    Designing table and index partitions is a DBA task that typically requires a joint effort with the database development team. The DBA must have a strong understanding
    of the database, tables, and columns to make the correct choices for partitioning. For more information on partitioning, review Books Online.
    Enhancements to Partitioning in SQL Server 2012
    SQL Server 2012 now supports as many as 15,000 partitions. When using more than 1,000 partitions, Microsoft recommends that the instance of SQL Server have at
    least 16Gb of available memory. This recommendation particularly applies to partitioned indexes, especially those that are not aligned with the base table or with the clustered index of the table. Other Data Manipulation Language statements (DML) and Data
    Definition Language statements (DDL) may also run short of memory when processing on a large number of partitions.
    Certain DBCC commands may take longer to execute when processing a large number of partitions. On the other hand, a few DBCC commands can be scoped to the partition
    level and, if so, can be used to perform their function on a subset of data in the partitioned table.
    Queries may also benefit from a new query engine enhancement called partition elimination. SQL Server uses partition enhancement automatically if it is available.
    Here’s how it works. Assume a table has four partitions, with all the data for customers whose names begin with R, S, or T in the third partition. If a query’s WHERE clause
    filters on customer name looking for ‘System%’, the query engine knows that it needs only to partition three to answer
    the request. Thus, it might greatly reduce I/O for that query. On the other hand, some queries might take longer if there are more than 1,000 partitions and the query is not able to perform partition elimination.
    Finally, SQL Server 2012 introduces some changes and improvements to the algorithms used to calculate partitioned index statistics. Primarily, SQL Server 2012
    samples rows in a partitioned index when it is created or rebuilt, rather than scanning all available rows. This may sometimes result in somewhat different query behavior compared to the same queries running on SQL Server 2012.
    Administrating Data Using Partition Switching
    Partitioning is useful to access and manage a subset of data while losing none of the integrity of the entire data set. There is one limitation, though. When
    a partition is created on an existing table, new data is added to a specific partition or to the default partition if none is specified. That means the default partition might grow unwieldy if it is left unmanaged. (This concept is similar to how a clustered
    index needs to be rebuilt from time to time to reestablish its fill factor setting.)
    Switching partitions is a fast operation because no physical movement of data takes place. Instead, only the metadata pointers to the physical data are altered.
    You can alter partitions using SQL Server Management Studio or with the ALTER TABLE...SWITCH
    Transact-SQL statement. Both options enable you to ensure partitions are
    well maintained. For example, you can transfer subsets of data between partitions, move tables between partitions, or combine partitions together. Because the ALTER TABLE...SWITCH statement
    does not actually move the data, a few prerequisites must be in place:
    • Partitions must use the same column when switching between two partitions.
    • The source and target table must exist prior to the switch and must be on the same filegroup, along with their corresponding indexes,
    index partitions, and indexed view partitions.
    • The target partition must exist prior to the switch, and it must be empty, whether adding a table to an existing partitioned table
    or moving a partition from one table to another. The same holds true when moving a partitioned table to a nonpartitioned table structure.
    • The source and target tables must have the same columns in identical order with the same names, data types, and data type attributes
    (length, precision, scale, and nullability). Computed columns must have identical syntax, as well as primary key constraints. The tables must also have the same settings for ANSI_NULLS and QUOTED_IDENTIFIER properties.
    Clustered and nonclustered indexes must be identical. ROWGUID properties
    and XML schemas must match. Finally, settings for in-row data storage must also be the same.
    • The source and target tables must have matching nullability on the partitioning column. Although both NULL and NOT
    NULL are supported, NOT
    NULL is strongly recommended.
    Likewise, the ALTER TABLE...SWITCH statement
    will not work under certain circumstances:
    • Full-text indexes, XML indexes, and old-fashioned SQL Server rules are not allowed (though CHECK constraints
    are allowed).
    • Tables in a merge replication scheme are not allowed. Tables in a transactional replication scheme are allowed with special caveats.
    Triggers are allowed on tables but must not fire during the switch.
    • Indexes on the source and target table must reside on the same partition as the tables themselves.
    • Indexed views make partition switching difficult and have a lot of extra rules about how and when they can be switched. Refer to
    the SQL Server Books Online if you want to perform partition switching on tables containing indexed views.
    • Referential integrity can impact the use of partition switching. First, foreign keys on other tables cannot reference the source
    table. If the source table holds the primary key, it cannot have a primary or foreign key relationship with the target table. If the target table holds the foreign key, it cannot have a primary or foreign key relationship with the source table.
    In summary, simple tables can easily accommodate partition switching. The more complexity a source or target table exhibits, the more likely that careful planning
    and extra work will be required to even make partition switching possible, let alone efficient.
    Here’s an example where we create a partitioned table using a previously created partition scheme, called Date_Range_PartScheme1.
    We then create a new, nonpartitioned table identical to the partitioned table residing on the same filegroup. We finish up switching the data from the partitioned table into the nonpartitioned table:
    CREATE TABLE TransactionHistory_Partn1 (Xn_Hst_ID int, Xn_Type char(10)) ON Date_Range_PartScheme1 (Xn_Hst_ID) ; GO CREATE TABLE TransactionHistory_No_Partn (Xn_Hst_ID int, Xn_Type
    char(10)) ON main_filegroup ; GO ALTER TABLE TransactionHistory_Partn1 SWITCH partition1 TO TransactionHistory_No_Partn; GO
    The next section shows how to use a more sophisticated, but very popular, approach to partition switching called a sliding
    window partition.
    Example and Best Practices for Managing Sliding Window Partitions
    Assume that our AdventureWorks business is booming. The sales staff, and by extension the AdventureWorks2012 database, is very busy. We noticed over time that
    the TransactionHistory table is very active as sales transactions are first entered and are still very active over their first month in the database. But the older the transactions are, the less activity they see. Consequently, we’d like to automatically group
    transactions into four partitions per year, basically containing one quarter of the year’s data each, in a rolling partitioning. Any transaction older than one year will be purged or archived.
    The answer to a scenario like the preceding one is called a sliding window partition because
    we are constantly loading new data in and sliding old data over, eventually to be purged or archived. Before you begin, you must choose either a LEFT partition function window or a RIGHT partition function window:
    1. How
    data is handled varies according to the choice of LEFT or RIGHT partition function window:
    • With a LEFT strategy, partition1 holds the oldest data (Q4 data), partition2 holds data that is 6- to 9-months old (Q3), partition3
    holds data that is 3- to 6-months old (Q2), and partition4 holds recent data less than 3-months old.
    • With a RIGHT strategy, partition4 holds the holds data (Q4), partition3 holds Q3 data, partition2 holds Q2 data, and partition1
    holds recent data.
    • Following the best practice, make sure there are empty partitions on both the leading edge (partition0) and trailing edge (partition5)
    of the partition.
    • RIGHT range functions usually make more sense to most people because it is natural for most people to to start ranges at their lowest
    value and work upward from there.
    2. Assuming
    that a RIGHT partition function windows is used, we first use the SPLIT subclause of the ALTER PARTITION FUNCTIONstatement
    to split empty partition5 into two empty partitions, 5 and 6.
    3. We
    use the SWITCH subclause
    of ALTER TABLE to
    switch out partition4 to a staging table for archiving or simply to drop and purge the data. Partition4 is now empty.
    4. We
    can then use MERGE to
    combine the empty partitions 4 and 5, so that we’re back to the same number of partitions as when we started. This way, partition3 becomes the new partition4, partition2 becomes the new partition3, and partition1 becomes the new partition2.
    5. We
    can use SWITCH to
    push the new quarter’s data into the spot of partition1.
    Tip
    Use the $PARTITION system
    function to determine where a partition function places values within a range of partitions.
    Some best practices to consider for using a slide window partition include the following:
    • Load newest data into a heap, and then add indexes after the load is finished. Delete oldest data or, when working with very large
    data sets, drop the partition with the oldest data.
    • Keep an empty staging partition at the leftmost and rightmost ends of the partition range to ensure that the partitions split when
    loading in new data, and merge, after unloading old data, do not cause data movement.
    • Do not split or merge a partition already populated with data because this can cause severe locking and explosive log growth.
    • Create the load staging table in the same filegroup as the partition you are loading.
    • Create the unload staging table in the same filegroup as the partition you are deleting.
    • Don’t load a partition until its range boundary is met. For example, don’t create and load a partition meant to hold data that is
    one to two months older before the current data has aged one month. Instead, continue to allow the latest partition to accumulate data until the data is ready for a new, full partition.
    • Unload one partition at a time.
    • The ALTER TABLE...SWITCH statement
    issues a schema lock on the entire table. Keep this in mind if regular transactional activity is still going on while a table is being partitioned.

  • How can I move the ODI Work Repository from one server to another server?

    How can I move the ODI Work Repository from one server to another server?

    Hi,
    If you would like to move your source models, target models and project contents from Work repository 1 to another work repository.
    I.e. Dev. server to Prod Server.
    1. Firstly, replicate the master repository connections i.e. with same naming conventions manually
    2. Go to Dev. Server work repository -> File Tab -> Click on Export work repository (save it in a folder)
    3. After exporting, you can view the xml files in the folders.
    4. Now, Open the Prod. server and make sure you already replicated mas. rep. details.
    5. Now, right click on model and import source model in synonym mode insert_update (select source model from the folder where your xml file located)
    6. Similarily, import again target then Project.
    Now, check. It should work.
    Thank you.

  • Delete Fact and Dimension Tables

    Hai All,
              Small question! When deleting data from info cube, it asks whether to delete just Dimension table or both fact and Dimension tables.
    What is the difference between these two?
    Thank you.

    Hi Visu,
    The dimension table will contain the references to char value by way of SID and DIM ids, whereas the fact table will contain the number (of key figures). If you delete just the Fact table, the numbers go away, yet the DIM ids remain intact, so reload is faster. But if you are convinced that this data is not correct either, or you want a clean slate to strat reload again, then delete both Fact and Dim tables. Then when you reload, the DIM ids will be created again.
    Hope this helps...

  • DWH: how do you analyze fact and dimension tables

    Hi,
    I was wondering how you analyze your fact and dimension tables.
    Our fact table is partitioned per month. Each partition contains 4M rows and is 270 MB large. We are using 9 dimensions, 6 have about 50'000 rows (2MB), 1 about 1M rows (50MB) and 2 about 3M rows (200MB). All tables are compressed. The version of Oracle we are using is 9.2.0.5.
    What I was wondering is how you would, using dbms_stats, analyze the fact and dimension tables. Which percentage would you analyze? On which column would you build histograms?

    nope, but i could copy-paste the URL or I could copy-paste the entire thread from the other forum. Id did the one that made more sense to me.

  • Best practice when FACT and DIMENSION table are the same

    Hi,
    In my physical model I have some tables that are both fact and dimension table, i.e. in the BMM they are of course separated into Fact and Dim source (2 different units) and it works fine. But I can see that there will be trouble when having more fact tables and I e.g. have a Period dimension pointing to all the different fact tables (different sources).
    Seems like the best solution to this is to have an alias of the fact/transaction table and have 2 "copies" of the transaction table (one for fact and one for dimension table) in the physical layer. Only bad thing is that there will then allways be 2 lookups in the same table when fetching data from the dimension and the fact table.
    This is not built on a datawarehouse - so the architecture is thereby more complex. Hope this was understandable (trying to make a short story of it).
    Any best practice on this? Or other suggestions.

    Id recommend creation of a view in the database. if its an oracle DB, materialised views would be a huge performance benefit. you just need to make sure that the MVs are updated when the source is updated.

  • Fact and Dimension tables

    Hi all,
    Please let me know the relation between the fact and dimension table(s).
    regards
    chandra kanth.

    Hi Chandra, it would be useful if you read a little bit about BI before start working with a BI tool.
    Anyway, I'll try to help you.
    A dimension is a structure that will be join to the fact table to so that users can analyze data from different point of views and levels. The fact table will most probably (not always) have data at the lowest possible level. So, let's suppose you have SALES data for different cities in a country (USA). Your fact table will be:
    CITY --- SalesValue
    Miami --- 100
    NYC --- 145
    Los Angeles --- 135 (because Arnold is not managing the State very well ;-) )
    You will then can have a Dimension table with the "Country" structure. This is, a table containing the different cities along with their states, counties, and finally the country. So your dimension table would look like:
    NATION --- STATE --- COUNTY --- CITY
    USA --- Florida --- Miami --- Miami
    USA --- NY ---- NY --- NYC
    USA --- Los Angeles --- LA --- Los Angeles
    This dimension will allow you to aggregate the data at dffirent lavels. This is, the user will not only be able to see data at the lowest level, but also at the County, State and Country level.
    You will join your fact table (field CITY) with your dimension table (field CITY). The tool will then help you with the aggregation of the values.
    Ihope this helps.
