Transparent gateway to SQL Server performance

I have a view created in Oracle on some tables in an SQL Server database.
When I run a select on the view it takes very long to complete. Several minutes in fact.
When i run the select that the view is built "as" (create view v_name as select....)
it completes in just a few seconds. Is there some type of performance hit when you select from a view built in Oracle that includes tables from SQL Server?

assuming your mentioned query running on Oracle, you can check the execution plan and statistics of two different behavior with sql*plus autotrace option - http://www.bhatipoglu.com/entry/17/oracle-performance-analysis-tracing-and-performance-evaluation

  • Free download of transparent gateway for SQL Server

    Can anyone give me the URL where I can download the transparent gateway for SQL Server.. I searched OTN but couldn't find it. I just want to try it out..
    Thanks.

    The indicated URL also shows the zip for the 10gR2 gateways for Windows software: 10201_gateways_win32.zip
    To use a gateway you also have to use an Oracle database as a so-called integrating kernel. In this Oracle database you define the database link to the gateway to be able to connect to SQL Server.
    But TG4MSQL 10gR2 has been desupported, which means that bugfixing has been stopped. Also just to make clear, allthough the software can be freely downloaded the product itself requires a license when you decide to use it after testing it.
    And I recommend to try the DG4MSQL 11gR1 software instead, it can also be found at Oracle Technet:
    http://www.oracle.com/technology/software/products/database/oracle11g/111070_win32_2008soft.html
    When using a 11gR1 database gateway the Oracle database you use with the gateway must be 10.2.0.4.0 or higher. Or have a closer look at Metalink document: 457808.1 - Database Patch 5965763 Required For Pre-11g Databases Using 11g Database Gateways
    Look for: win32_11gR1_gateways.zip

  • Oracle 9i on LINUX Transparent Gateway for SQL Server

    Does anybody know if there is a Transparent Gateway available for Oracle 9i on LINUX to connect to SQL Server? I have run the installer and cannot seem to find the install options for any Transparent Gateways. I am familiar with their location in the universal installer as I have installed the Oracle/SQL Server Transparent Gateway with Oracle in WinNT. Perhaps Transparent Gateways for Oracle/LINUX are not available?
    Thanks in advance.

    I have the same issue - we want to upgrade our 9.2 to 10g Linux, and need to maintain connectivity to some legacy sqlserver databases. I can't find any mention of tg4msql for linux. What gives? Anyone know the answer to this? thanks, michael

  • Transparent gateway to Sql Server losing the "\" in the SqlServer Connect s

    HS_FDS_CONNECT_INFO="Sql2k5-Stats/SQL2K5-STATS\SQL2K5STATS/AZDPS"
    No matter what we [inc Oracle support] put in here, somewhere it gets removed before it hits Sql Server
    it gets turned into Sql2k5-Stats\SQL2K5-STATSSQL2K5STATS and sqlplus barfs an error about not being able to connect to remote and that is because the "\" has been removed.
    Have tried numerous combinations for HS_FDS_CONNECT_INFO
    Any ideas out there ?
    Edited by: IanSparkes on Jun 23, 2009 12:01 PM

    When connecting to SQL Server instances, you can define a SQL Server alias using the MS Client Configuration Tool or you can use two back slashes:
    HS_FDS_CONNECT_INFO="SQLSERVER\\instance2.Northwind"
    or using the SERVER and DATABASE naming convention:
    HS_FDS_CONNECT_INFO="SERVER=<SERVER NAME>\\<INSTANCE NAME>;DATABASE=<DATABASE>"

  • Cannot find where to download Gateway for SQL Server

    I have searched OTN every which way to find the Oracle Transparent Gateway for SQL Server. I have checked my CD's and I have every one imaginable but not the one for SQL server. Why? Where is it hidden? I am trying to connect to a SQL Server 6.0 and an Oracle 8.1.6.3 Database at the same time.

    Hello,
    All of the downloads are [url http://www.oracle.com/technology/software/products/jdev/htdocs/soft11.html]here. According to the [url http://www.oracle.com/technology/products/jdev/collateral/papers/11/certification/index.html]certification page, JDev 11.1.1.3 is certified against Windows 2008 server, so I'd start by downloading the Windows version from there (even though they didn't update the description to say "for windows 2008")

  • Problem with "Database Gateway for SQL Server"

    Hello,
    i am testing the different technologies for connecting an oracle database with a sql-server database.
    The way using 10g-generic-connectivity with ODBC works fine, but the 11g-DG4MSQL makes problems.
    Environment:

    Server OBELIXUS (32bit Windows 2000 Sp4) with MS-SQL-Server 2005
    On PEGASUS i have installed the gateway in a new oracle home directory:
    "D:\oracle\product\10.2.0\db_1" => home directory of 10g
    "D:\oracle\product\11.1.0\tg_1\" => home directory of the gateway

    At first your configuration is not really correct.
    =====================================================
    In the LISTENER.ORA from 10g, you must only refer to the database and hsodbc 10g

  • Using SSAS to analyze sql server performance

    Hi Folks,
    I have a database repository database where i store info about all 160 sql servers.
    Can i use ssas to analyze that data i am dba is there any sample cube which does this stuff.
    Any help highly appreciated !!
    Thanks,
    Ashwin.

    Hi Ashwin,
    According to your description, all 160 SQL servers information were stored in the repository database, now what you want is using SQL Server Analysis Services, right?
    Analysis Services is a data source that serves as the Semantic layer for all your BI clients. It’s where you can define important business entities such as product lines or service offerings in one place with all the key metrics
    supporting them. In your scenario, if you have created a multidimensional database based on this database, you can create several of KPI to analyze the servers' performance. Here are some links for you reference.

    If you haven't create a SSAS database, you can refer to the link below to see how to monitor multiple servers.

  • Importing from SQL Server - Performance

    Hello,
    I am developing an Access 2010 database with a SQL Server 2008 R2 backend. I would be interested in getting some feedback on which method of retrieving the results from SQL Server and displaying them in Excel would show the best performance. Assume the following
    options.
    1. Create a pass-through query in Access and execute the following VBA code;
    Set qdf = db.QueryDefs("qry_Passthrough")
    SQL = "SELECT * FROM qry_Passthrough WHERE ID = 1"
    Set rst = qdf.OpenRecordset(SQL, dbOpenSnapshot)
    2. Create a pass-through query in VBA code;
    Set qdf = db.CreateQueryDef("")
    qdf.SQL = "SELECT * FROM tbl_Data WHERE ID = 1"
    Set rst = qdf.OpenRecordset(dbOpenSnapshot)
    3. Create an inline table valued function (itvf_Data) and pass in the ID parameter;
    Set qdf = db.CreateQueryDef("")
    qdf.SQL = "SELECT * FROM dbo.itvf_Data (1)"
    Set rst = qdf.OpenRecordset(dbOpenSnapshot)
    4. Create a View in SQL Server and return the results;
    Set qdf = db.CreateQueryDef("")
    qdf.SQL = "SELECT * FROM vw_Data WHERE ID = 1"
    Set rst = qdf.OpenRecordset(dbOpenSnapshot)
    5. Create a linked View in Access to reference vw_Data;
    SQL = "SELECT * FROM dbo_vw_Data WHERE ID = 1"
    Set rst = qdf.OpenRecordset(SQL, dbOpenSnapshot)

    1.,2.: As long as it's a passthrough the creation of it does not influence the performance.
    3.: A TVF is a good development tool. As long as you call it only with parameters, it's imho okay. The problems begin when you need additional condtions. Adding them as WHERE clause may affect performance, cause SQL Server cannot optimize them well.
    4./5. Server-side views are clearly the best approach. Due to o9ptimization and plan caching by SQL Server.

    Hello,
    Your output you posted does not makes sense or may be I am not able to understand it..If you want through analysis I need following from you
    1.
    select
    (physical_memory_in_use_kb/1024)Memory_usedby_Sqlserver_MB,
    (locked_page_allocations_kb/1024 )Locked_pages_used_Sqlserver_MB,
    (total_virtual_address_space_kb/1024 )Total_VAS_in_MB,
    process_physical_memory_low,
    process_virtual_memory_low
    from sys. dm_os_process_memory
    2 What is reason for keeping Max server memory and Min server mmory almost equal. 55 G is MAX and 45 G is min.
    3. Does SQL server account has locked pages in memory privilege ?
    4. Did you see any out of memory error ?
    5 Please post output of DBCC MEMORYSTATUS and SP_readerrorlog on skydrive and post location here.
    PS: SQL server utilizing memory is normal behavior ,what you posted does not exactly points to memory pressure and what seems to me cause here is poorly written queries running.

  • Accessing SQL Server from ORACLE using Transparent Gateway

    So I had downloaded the gateway installer and was following the guide here to set up the Transparent Gateway for SQL Server: http://www.orafusion.com/art_orahs.htm
    After I had created the database link, I was prompted the following error when trying to do a simple select statement from the SQL Server DB:
    >
    ORA-12154: TNS:could not resolve service name
    12154. 00000 - "TNS:could not resolve the connect identifier specified"
    *Cause:    A connection to a database or other service was requested using
    a connect identifier, and the connect identifier specified could not
    be resolved into a connect descriptor using one of the naming methods
    configured. For example, if the type of connect identifier used was a
    net service name then the net service name could not be found in a
    naming method repository, or the repository could not be
    located or reached.
    *Action:  
    - If you are using local naming (TNSNAMES.ORA file):
    - Make sure that "TNSNAMES" is listed as one of the values of the
    NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
    (SQLNET.ORA)
    - Verify that a TNSNAMES.ORA file exists and is in the proper
    directory and is accessible.
    - Check that the net service name used as the connect identifier
    exists in the TNSNAMES.ORA file.
    - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
    file. Look for unmatched parentheses or stray characters. Errors
    in a TNSNAMES.ORA file may make it unusable.
    - If you are using directory naming:
    - Verify that "LDAP" is listed as one of the values of the
    NAMES.DIRETORY_PATH parameter in the Oracle Net profile
    (SQLNET.ORA).
    - Verify that the LDAP directory server is up and that it is
    accessible.
    - Verify that the net service name or database name used as the
    connect identifier is configured in the directory.
    - Verify that the default context being used is correct by
    specifying a fully qualified net service name or a full LDAP DN
    as the connect identifier
    - If you are using easy connect naming:
    - Verify that "EZCONNECT" is listed as one of the values of the
    NAMES.DIRETORY_PATH parameter in the Oracle Net profile
    (SQLNET.ORA).
    - Make sure the host, port and service name specified
    are correct.
    - Try enclosing the connect identifier in quote marks.

    Can anyone assist me? thanks!

    Hi kgronau,
    >
    After changing a listener.ora file you need to STOP and START the listener to get the changes loaded. It looks like your listener is not serving the 1524 port which could be related to the fact that you didn't stop/start the listener after you've edited the listener.ora file.
    ... But as stated earlier - please do not use a 10.2 listener to start an 11g gateway. Instead configure the listener of the gateway home.
    >
    I did restart my listener under services.msc whenever I make the changes but there are no effect. Please also note that I can only find "OracleOraDb10g_home1TNSListener" under my services.msc. There is no 11.2 Listener. I did install the gateway and the installation was successful as far as I can tell. But perhaps because there's no 11.2 Listerner under my services.msc, could that mean it was a bad installation?
    >
    Next point is the tnsping you've used is 11.2. You need to make sure that you use the tnsping of the Oracle Database home as the database initiates the gateway connection so the database home tnsnames,ora needs the tns entry for the gateway.
    >
    My current PATH environment variables setting is as follow: C:\oracle\product\11.2.0\tg_1\bin;C:\oracle\product\10.2.0\db_1\bin; So perhaps, I just need to ensure the 10.2 ORACE home is the first?
    >
    As a final tip: There are so many web sites explaining how to configure DG4ODBC - many of them are faulty. If you need a reliable configuration, please have a look at "My Oracle Support" => How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on Windows 32bit to Connect to Non-Oracle Databases Post Install     [Document 466225.1]     )

  • SQL Server 2005 (64-bit) - 10.1/10.2 via Transparent Gateway

    From what I gather, there is no 64-bit Transparent Gateway for SQL Server. Has anyone used the 32-bit gateway with a 64-bit SQL Server instance? Will this even work?
    Also, what are the ramifications for the Oracle instances -- will this setup work with both 32-bit & 64-bit 10.1/10.2 instances?
    Thanks!
    -charles.

    Can you provide some context as to whay you think this will not work? The gateway is just a client to the 64 bit SQL Server. I'm sure that 64 bit server supports access from clients that are running 32 bit operating systems.

Maybe you are looking for
