DB statistic missing & Missing index for critical tables  after TDM refresh

Hello SAP expert,
We have completed our refresh using TDM, but after the refresh we encounter problem at the receiver system,
Issue Encounter
1. System too slow
2. When running tcode it resulted to time_out dump
3. Db statistics are missing
4. missing index for critical tables
Appreciate your help. How can we check tdm log if the data transfer really transferred or completed succesfuly.
Thanks

Thanks for your reply.
We are looking the possible root cause of the issue, everything is fine in the target system before the refresh even the DB statistics update job is working fine before the refresh.
is there a way we could find logs or report from tdms server if there something happen during the execution of the tdm jobs or data selection and transfer. as we only find logs of the latest run. let say we execute the data transfer 4 times where we could find a report or logs stating the error or execution logs from the 2nd or on 3rd run?
thanks

    Hi,
    these looks like active tables of ODS/DSOs...
    You position you cursor on the missing object in DB02 and hit the create in DB button; better choose in background.
    Note that they will remain showing missing in DB02 until statistics are refreshed...
    After the background jobs are completed hit the dsplay definition button; you will be lead to the SE14 screen for this IDX; it should say that the index exists in the DB;
    Tomorrow your DB02 screen should be updated...
    hope this helps...

  • How to create index for particular table in R3

    Hi
    My load is taking too much time and it leads to process over due error. Does creating indexes on table in r3 side will solve this issue? If so how can we find out on which table does this particular data source depend. I went to maintain extract structure and findout only one table is supplying data for this data source.
    Is there any other factors depend to solve this.
    Thanks
    kk

    Hi,
    it will depend on the table.... Having an index created will speed up the loading but slow down the insert therefore slowing some process perhaps...
    May I ask which table it is? And which fields would you need to index?
    Are you sure that bottleneck is located in R/3? Analyze your loading time in the monitor and see if this is really the case.
    Otherwise you can create index for a table in Tx SE11; first check if an index is not already created...
    hope this helps,

  • Need a dump on indexes for a table

    RDBMS novice here asking what is probably an easy one.
    How, in SQLPlus, can I get a spill on all the indexes of a specific table. In Oracle Rdb, the statement "show table (indexes) foo;" did the job. Looking for something similar in RDBMS. I need to see the components of the index (in their right order). It would also be great to see some of the other stuff you specify when you create the index.
    Thanks in Advance

    You can get the indexes for a table by querying
    SELECT INDEX_NAME FROM USER_INDEXES WHERE TABLE_NAME='XXX'
    You can get the columns within the index (in order) by
    SELECT COLUMN_NAME FROM USER_IND_COLUMNS WHERE INDEX_NAME='XXX' ORDER BY COLUMN_POSITION

  • Index for a table

    I would like to ask when it makes sense to create an index for a table, e.g. ONRVB at the moment it takes 3.006.358 ms to select one enntry.

    Hi Witold
    It is always better to optimize your where clause rather creating index. Before creating any index you should first check what is the frequency of its usage. Moreover many a times creating index ends up in having side effects as some times database engine may choose ur new index instead which could be not be valuable. Hence before creating any index we need to think twice and try to optimize what we have.

  • When do I really need to create indexes for a table?

    Once I was talking to a dba in a conference.
    He told me that not always I have to create indexes for a single table, it depends of its size.
    He said that Oracle read registers in blocks, and for a small table Oracle can read it fully, in a single operation, so in those cases I don't need indexes and statistcs.
    So I would like to know how to calculate it.
    When do I really need to create indexes for a table?
    If someone know any documment that explain that, or have some tips, I'd aprecciate.
    Thanks.
    P.S.: The version that I'm using is Oracle 9.2.0.4.0.

    Hi Vin
    You mentioned so many mistakes here, I don't know where to begin ...
    vprabhu_2000 wrote:
    There are different kinds of Index. B-tree Index is by default. Bit map index, function based index,index organized table.
    B-tree index if the table is large This is incorrect. Small tables, even those consisting of rows within just one block, can benefit from an index. There is no table size too small in which an index might not be benefical. William Robertson in his post references links to my blog where I discuss this.
    and if you want to retrieve 10 % or less of data then B-tree index is good. This is all wrong as well. A FTS on a (say) million row table could very well be more efficient when retrieving (say) just 1% of data. An index could very well be more efficient when retrieving 100% of data. There's nothing special about 10% and there is no such magic number ...
    >
    Bit Map Index - On low cardinality columns like Sex for eg which could have values Male,Female create a bit map index. Completely and utterly wrong. A bitmap index might be the perfect type of index, better than a B-Tree, even if there are (say) 100,000 distinct values in the table. That a bitmap index is only suitable for low cardinality columns is just not true. And what if it's an OLTP application, with lot's of concurrent DML on the underlining table, do you really think a bitmap index would be a good idea ?
    >
    You can also create an Index organized table if there are less rows to be stored so data is stored only once in index and not in table. Not sure what you mean here but an IOT can potentially be useful if you have very large numbers of rows in the table. The number of rows has nothing to do with whether an IOT is suitable or not.

    Hope this info helps. Considering most of it is wrong, I'm not sure it really helps at all :(

  • Why should we create index on  the table after inserting data ?

    Please tell me the Reason, why should we create index on the table after inserting data .
    while we can also create index on the table before insertion of the data.

    The choice depends on a number of factors, the main being how many rows are going to be inserted in the table as a percentage of the existing rows, or the percentage growth.
    Creating index after a table has been populated works better when the tables are large or the inserts are large for the following reasons
    1. The sort and creation of index is more efficient when done in batch and written in bulk. So works faster.
    2. When the index is being written blocks get acquired as more data gets written. So, when a large number of rows get inserted in a table that already has an index , the index data blocks start splitting / chaining. This increases the "depth" of the inverted b-tree makes and that makes the index less efficient on I/O. Creating index after data has been inserted allows Orale to create optical block distribution/ reduce splitting / chaining
    3. If an index exists then it too is routed through the undo / redo processes. Thats an overhead which is avoided when you create index after populating the table.

  • Any more update for Nokia N8 after belle refresh??...

    Hello guys...great work on your part for providing new updates for nokia n8.... Its really great on your part...now my phone is fantastic...
    Just wanted to know if Nokia is planning to release new updates for the N8, after Belle Refresh??
    If new updates are coming in the near future,please do let us know sir.
    From- Nokia N8 lover.

    @GEN82012, this is probably the wrong thread for enquiring on updates but...
    No you can't download directly from Nokia if the update hasn't been released for your product code.
    Updates are by Product Code, type *#0000# on the Call screen. For example mine is 059C7R0.
    These codes are country and operator specific.
    Be aware there is a difference between a "Vanilla" handset brought directly from Nokia and an "Unlocked" one.
    If a carrier "Unlocks" the handset it means you can use it on other networks but the Product Code will remain the original one and can't be changed.
    If the phone has been repaired at some stage it may have a non standard board in it as well and I think those can only be updated at Nokia Care.
    If you take the phone to Nokia Care with proof that it is legally unlocked they may be willing to load the local "Vanilla" variant for you.
    Note; mine has recently updated to  111.040.1511.
    N95 (RM159) V31.0.017, N8 (RM596) Belle 111.040.1511

  • How much time it take to rebuild an index for a table with 20 millions rows

    Hi all,
    i need to rebuild the index of a table containing 20 000 000 row (i don't know why the other people working on this didn't think of rebuilding the index regularly, because i asked and apparently it has never been done :cry: :cry:) i am not a sql developper nor a DBA so i can't mesure how long it take to rebuild the index, does any one have an idea (aproximativly of course :aie:), the other question is there any formula to use in order to calculate how often to rebuild the indexes (i can for example retieve how much rows are delated or inserted daily ...)
    Thanks again

    :aie: that's why i am asking because i don't know (and to be sure which solution is best)
    so the table is like this (the columns) :
    45 varchar2, 5 timestamp, 30 Number no LOB columns, (15 indexes : 5 unique indexes and that those indexes uses at a maximum 4 columns)15 indexes - 100,000 deletes: this could mean 1,500,000 block visits to maintain index leaf blocks as the table rows are deleted. If you're unlucky this could turn into 1,500,000 physical block read requests; if you're lucky, or the system is well engineered this could be virtually no physical I/O. The difference in time could be huge. At any rate it is likely to be 1,500,000 redo entries at 250 - 300 bytes per entry for a total of about 400MB of redo (so how large are your redo logs and how many log switches are you going to cause).
    yes the tables is used by an application so (update, insert ) can take place at any time
    for the deletion , there is the batch which does a mass delete on the table ( 4 or 5 time each day)
    You haven't answered the question - how long does it take to do a sample batch delete.
    If you can enable SQL tracing, or take a before/after snapshot of v$sesstat or v$session_event for the session as it does the delete then you can get some idea of where the time is going - for all you know it might be spending most of its time waiting for a lock to do away.
    >
    "How many leaf blocks are currently allocated to the index(es) ?" how can i answer to this question ? may be if i check the all_objects table ?
    If you keep your statistics up to date then dba_indexes is a good place, cross-checked with dba_segments, and you can use the dbms_space package for more detail. I have a code sample on my blog which allows you to compare the current size of your indexes with the size they would be if rebuilt at some specific percentage: http://jonathanlewis.wordpress.com/index-sizing/ (It's such good code that Oracle Corp. has copied it into MOS note 989186.1)

  • CC&B 2.3.1 - Custom indexes for base tables

    Hi,
    We are seeing a couple of statements in the database that could improve its performance with new custom indexes on base tables. Questions are:
    - can we create new indexes on base tables ?
    - is there any recommendations about naming, characteristics and location for this indexes ?
    - is there any additional step to do in CC&B in order to use the index (define metadata or ...) ?
    Thanks.
    Regards.

    Hi,
    if it necessary You can crate custom index.
    In this situation You should follow naming convention from Database Design Standards:
    Indexes
    Index names are composed of the following parts:
    +[X][C/M/T]NNN[P/S]+
    +•     X – letter X is used as a leading character of all base index names prior to Version 2.0.0. Now the first character of product owner flag value should be used instead of letter X. For client specific implementation index in Oracle, use CM.+
    +•     C/M/T – The second character can be either C or M or T. C is used for control tables (Admin tables). M is for the master tables. T is reserved for the transaction tables.+
    +•     NNN – A three-digit number that uniquely identifies the table on which the index is defined.+
    +•     P/S/C – P indicates that this index is the primary key index. S is used for indexes other than primary keys. Use C to indicate a client specific implementation index in DB2 implementation.+
    Some examples are:
    +•     XC001P0+
    +•     XT206S1+
    +•     XT206C2+
    +•     CM206S2+
    Warning!  Do not use index names in the application as the names can change due to unforeseeable reasons
    There is no additional metadata information for indexes in CI_MD* tables - because change of indexes does not influence generated Java code.
    Hope that helps.

  • Problem while creating index for temporary table...

    Hi,
    i have created index for a temporary table and this script should used by multiusers.So when second user connecting to it is giving index i mean object already exists.
    So what i need is when the second user connected the script should create one more index on temporary table.Will sql server provide any random way of creating indexes if the index exists already with that name??
    Thank You,

    Nope..
    SQL Server is cleaver enough to handel this situation.
    When you create a index or constraint on the Temp Table, eventhough the index name is duplicate it will allow.
    But it only possible on temp tables (prefixed with single #).
    To Test this,
    Open Two window,
    Execute the below window on the opened 2 window..
    create table #test
                id int
    Insert Into #test values(1);
    Insert Into #test values(2);
    Create clustered index testindex on #test(id)
    Now you wont get any error on any of the window. Rite?
    To fetch the created index details, execute the below code on any one of the window..
    select * from sysindexes where name like '%test%'
    Now you can see the 2 rows with same indexname but refereing with different table. Yes. all the temp tables (#) will be suffixed with unique number to avoid the object already found error while multiple users connects.

    select distinct      ID
    from      scdatabase4
    where ID < 253
    order by 1Since database is not my primary job and have no background of it, I'm really confused about what to do to fix my issues. Could someone please help me in assigning primary key and index if you agree that this is the problem?!

    Execute the query below to help decide what column to index:
    SELECT COLUMN_NAME, NUM_DISTINCT, NUM_NULLS, NUM_BUCKETS, DENSITY
    FROM DBA_TAB_COL_STATISTICS
    WHERE TABLE_NAME = 'your_table_name'
    ORDER BY COLUMN_NAME;
    The important columns are:
    1) NUM_DISTINCTS: Indicates the number of distinct values. If this number is very low for a column, it indicates that this column is not a very good candidate for a B-Tree index.
    2) NUM_NULL: Indicates the number of null values for each column. A column with few null values is a good candidate for a index
    But be aware, this is not a rule, it's just a method to help decide which column will have the most benefit of index creation.
