Oracle 11g Migration performance issue

Hello,
There a performance issue with Migration from Oracle 10g(10.2.0.5) to Oracle 11g(11.2.0.2).
Its very simple statement hanging for more than a day and later found that query plan is very very bad. Example of the query is given below:
INSERT INTO TABLE_XYZ
SELECT F1,F2,F3
FROM TABLE_AB, TABLE_BC
WHERE F1=F4;
While looking at cost in Explain plan :
on 10g --> 62567
0n 11g --> 9879652356776
Strange thing is that
Scenario 1: if I issue just query as shown below, will display rows immediately :
SELECT F1,F2,F3
FROM TABLE_AB, TABLE_BC
WHERE F1=F4;
Scenario 2: If I create a table as shown below, will work correctly.
CREATE TABLE TABLE_XYZ AS
SELECT F1,F2,F3
FROM TABLE_AB, TABLE_BC
WHERE F1=F4;
What could be the issue here with INSERT INTO <TAB> SELECT <COL> FROM <TAB1>?

  • Oracle 11g OEM job issue

    Hi all,
    After Oracle 11g migration, i have been facing issues in OEM scheduling. Twice the job did not run even after 11.2.0.7 upgrade. Hence i would like to explore the possibility of scheduling the same in DBMS jobs (we have not faced even a single failure since migration). However there is no mail alert available for successful completion of the job. In this regard i would like to have your views and help to create alerts to proceed further.
    Thankx

    Hi Ravi,
    Really the link helps,eventhough i have been looking for the rootcause to overcome from the job failure(scheduled jobs)
    Actually after completion/succeded of my scheduled job i may also get "INITIALIZATION ERROR" status message,so i need to be Re-schedule the particular job again
    for next day.
    Look up screenshot of the error

    Oracle 11g - External Table Issue?
    =====================
    I hope this is the right forum for this issue, if not let me, where to go.
    We are using Oracle 11g (11.2.0.1.0) on (Platform : solaris[tm] oe (64-bit)), Sql Developer 3.0.04
    We are trying to use oracle external table to load text files in .csv format. Here is our data look like.

    Any idea?

    I'm not sure, but maybe you should get rid of the redundancy that you have in your CREATE TABLE statement.
    This line covers all fields:
    FIELDS TERMINATED BY "," OPTIONALLY ENCLOSED BY '"'
    {code}
    So I would change the field list to:
    {code}
    DATE1 CHAR (10),
    DATE2 CHAR (10),
    POL_PRTY CHAR (30),
    P_NAME CHAR (30),
    P_ROLE CHAR (5)
    {code}
    It worked on my installation.

    Note that I had to interchange the two lines:

    Just to get the access parameters to parse correctly.
    I added two empty lines, one in the middle and one at the end - both were rejected.

  • Oracle 10g reports migration to Oracle 11g migration

    I have migrated oracle 10g reports to Oracle 11g reports and generated REP file. But when we execute REP file using RWRUN.EXE I am getting below error.
    ERR REP-50125: rwbuilder.conf:java.lang.NullPointerException
    ERR java.lang.NullPointerException
    to avoid this I tried below work arround which was posted in "https://forums.oracle.com/forums/thread.jspa?threadID=2365028" URL. but not success.
    1. Go to C:\Oracle\Middleware\asinst_1\config\FRComponent\frcommon\tools\admin
    2. Make a backup of the file 'cauprefs.ora'
    3. Open up the file in a text editor:
    --In the file, look for:

    ("oracle.reports.plugin.datasource.xmlpds.XMLDataSourceFactory",
    "oracle.reports.plugin.datasource.jdbcpds.JDBCDataSourceFactory",
    "oracle.reports.plugin.datasource.textpds.TextDataSourceFactory")
    --Replace the value to: Reports.PluggableDataSourceFactories = ()
    4. Save the file and try running Reports Builder again. Data Model should open up without crashing.
    Could you please help me to resolve this issue.

  • Oracle 11g Database Performance

    We have Oracle 11g (11.1.0.6) database on HP-UX (IA). It’s around 200G database, and we have lot of batch job and reports running against this database. This database is performing really bad, whenever we restart the application and the database its performing good batch jobs are running for 2 hrs, the time will increase gradually and after few days same job taking more that 20 hrs some times its not even complete we manually kill it.
    So I am guessing this is related to memory (SGA) issue, we have configured automatic memory management. But I don’t know where/what to look to find the root cause. Can some one help me to find a problem?

  • Oracle 11g Case Insensitive Issue

    Hi,
    For our .net framework 4.0 Application we need case insenstive search. So I have tried setting NLS_COMP=LINGUISTIC & NLS_SORT=BINARY_CI in environmental variable.. But this is not working. But when I tried firing trigger on each logon and setting NLS_COMP for each session.. It is working.. But because of performance reason we don't want to fire on trigger for each database logon.
    Pls Let me know why it is not working setting environmental variable. We are using Oracle 11g client and 10g server and connecting from our .net application through ODP.NET.
    Regards,
    Raghu

    Do you see the same behavior when connecting via SQLPlus after setting the environment variables? Is this an ODP.NET specific issue? If it's not specific to ODP, you'll probably get better insight by posting in one of the generic database forums.
    With respect to ODP specific solutions, have you already checked out the OracleGlobalization class?
    http://docs.oracle.com/cd/B19306_01/win.102/b14307/OracleGlobalizationClass.htm#i1009565
    Hope it helps,

  • Vb6 ODBC - Syntax error or access violation in oracle 11g migration

    Hi,
    We have VB6 application with Oracle 10g and the same is working fine.
    Now, we are migrating to Oracle 11g now and we have updated the odbc drivers too.
    { call M_FR(?, ?, ?, ?, ?, ?, ?, ?) }
    L_ID = 890083
    V_ID = 1
    SUB_ID = 6955141
    SUB_SEQ = 1
    P_CODE = 1
    L_SUP_TYPE = 1
    L_REF_NO = 1
    DELETE_REASON_CODE = 1
    When calling the above sp in oracle 11g getting error: [Microsoft][ODBC driver for Oracle]Syntax error or access violation.
    But user has all the right and no issue with access. Also no syntax error. In SQLplus the same is working fine.
    Kindly help us to resolve this issue.
    Regards,
    Sathiya

    Try downloading the latest version of the 8.1.6 driver off OTN.
    That sounds like a bug that was fixed a while ago.

  • SQLs erver migration performance issue

    We are performing migration from oracle to MSSQL server 2005 (Windows 2003/SAP 4.6D).Our target system configuration is like below:
    ->OS - Windows 2003 x64
    ->DB - MSSQL server 2005 SP4
    ->SAP - 4.6 D kernel
    ->CPU - 4 processors (2.67ghz each)
    ->RAM - 16 GB
    ->source system DB size - around 1 TB and package splitting was implemented.
    While importing the export dump that came from source system, we are facing load performance issue's.
    1) We have started 10 parallel processes and after import is started, CPU is getting 95% to 99% utilized and when we check SQL server studio-> Activity monitor we  found below information:
    -There were around 20 processes are in status sleeping
    -Only one or two system processes are running with commands - INSERT,SELECT INTO commands ( column)
    -At any point of time only two processes are running and CPU utilization is hitting high.
    -Import is very slow and its taking 35 hours to complete
    We have followed few SAP notes(1054852,1241751 e.tc..) and below are the settings for SQL server:
    -Minimum server memory - 5 GB
    - Maximum server memory - 5 GB
    - index creation memory - 0
    - Maximum memory per query - 1024 kb
    - Maximum degree of parellelism - 1
    - Parallellism locks - 0
    - Cost threshold of parellism - 5
    - Enabled trace flags - 610,620,1117,1211,3917
    - Windows environment variable BCP_BATCH_SIZE = 10000
    - SQL log file size - 100 GB
    - tempdb size - 20 GB
    2) When we tried another test import after tuning parameters (Maximum degree of parellelism to 3) and increasing r3load parallel processes to 20, we found  of inserts
    are overflowing in process list and blocking other waiting processes and putting them in suspended mode.CPU utilization is at 80%
    Are there any SQL server parameters need to be tuned to fix this import load time issue in both scenarios? Are there any  best practises for migrating to SQL server?
    Thanks..

    > 1) We have started 10 parallel processes and after import is started, CPU is getting 95% to 99% utilized and when we check SQL server studio-> Activity monitor we  found below information:
    What processes is using the CPU? The SQL Server itself or others? (see task manager)
    > -Minimum server memory - 5 GB
    > - Maximum server memory - 5 GB
    For the time of the migration itself I'd give the database more memory (10 GB or more) and reconfigure later when the import is done.
    What parameters do you use for the R3load? I'd recommend
    -loadprocedure fast -merge_bck -c 10000
    and also set
    BCP_LOB=1 in the environment.

  • Oracle Retail 13 - Performance issues when open, save, approving worksheets

    Hi Guys,
    Recently we started facing performance issues when we started working with Oracle Retail 13 worksheets from within the java GUI at clients desktops.
    We run Oracle Retail 13.1 powered by Oracle Database 11g R1 and AS 10g in latest release.
    Issues:
    - Opening, saving, approving worksheets with approx 9 thousands of items takes up to 15 minutes.
    - Time for smaller worksheets is also around 10 minutes just to open a worksheet
    - Also just to open multiple worksheets takes "ages" up to 10-15 minuts
    Questions:
    - Is it expected performance for such worksheets?
    - What is your experience with Oracle Retail 13 in terms of performance while working with worksheets - how much time does it normally take to open edit save a worksheet?
    - What are the average expected times for such operations?
    Any feedback and hints would be much appreciated.
    Cheers!!

    Hi,
    I guess you mean Order/Buyer worksheets?
    This is not normal, should be quicker, matter of seconds to at most a minute.
    Database side tuning is where I would look for clues.
    And the obvious question: remember any changes to anything that may have caused the issue? Are the table and index statistics freshly gathered?
    Best regards, Erik Ykema

  • Oracle 10g vs Oracle 11g query performance

    Hi everyone,
    We are moving from Oracle 10g to Oracle 11g database.
    I have a query which in Oracle 1g takes 85 seconds to run, but when I run the same query in Oracle 11g database, it takes 635 seconds.
    I have confirmed that all indexes on tables involved are enabled.
    Does anyone have any pointers, what should I look into. I have compared explain plans and clearly they are different. Oracle 11g is taking a different approach than Oracle 1g.
    Thanks

    Pl post details of OS versions, exact database versions (to 4 digits) and init.ora parameters of the 10g and 11g databases. Have statistics been gathered after the upgrade ?

  • As a number of Oracle Connections created - Performance Issue

    Hello,
    We are using Oracle 9i as a backend and VB 6.0 as Frontend. For one client one connection will be opened in the Database Server, if 200 clients open the application then 200 connections will be opened in the Database Server, due to that performance issue is raising.
    We are doing: If the frontend application is not in use for 10-minutes then the connection is closed and at the same time front-end application is also terminated or if the Client terminates the application the connection is closed in the Server.
    Eventhought if 200-Clients connect the Server only 4 to 5 Clients send a request to the Server for retriving or for saving the data.
    I want to Open a fixed number of connections in the DataBase Server eg., around 10-connections, and i want to use this 10 connections for 200 clients.
    At First 10 Connections are opened and 10 Clients are using this 10 connections, among 10 Clients 1 released the database connection after finishing the Job and if 11'th Client opens then this released connection as to be used without opening a new connection, in the same way if some of the connections from 9 get free and if any other clients open application then this connections which are free as to be used for opening the application or else for doing any transaction. So, that the number of connection to be create can be redused.
    Please give me the suggestion how to make use the released connection for doing the transaction or else for opening the application.
    Thanking U with Regards,
    Sravan,
    Hyderabad.

    As Satish mentioned, Shared Server can be a good solution, but it would also be worth telling us , how did you quantify this thing that due to the number of connections, you have a performance issue? 200 is not that big number I guess. What's the o/s , exact database version and the system details with database details? Also if you have statspack report, post that too over here.
