Failover mapviewer datasource

Hi all,
is it possible to configure a mapviewer jdbc datasource with failover cluster?
Something like this:
oracle:thin:@(DESCRIPTION=
(LOAD_BALANCE=on)
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=TCP)(HOST=host1)(PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=host2)(PORT=1521)))
(CONNECT_DATA=(SERVICE_NAME=service_name)))
A sample based on MVDEMO datasource would be helpful.

For completion of this thread:
This can be done by the use of a container defined data source that can be looked up by Mapivewer through JNDI as already discribed in chapter 7.1 of mapviewer documentation.

  • MapViewer metadata problem - accessing spatial data in a different schema.

    I have a MapViewer application that uses data from three different schemas.
    1. Dynamic Themes come from schema A.
    2. Static Themes come from schema B.
    3. A newly added static theme in B whose data comes from schema C.
    The mapviewer datasource points to schema B where the static themes, data and metadata are defined while the dynamic themes have their own datasource specified as part of addJDBCTheme(...).
    To get the newly added map to work I've had to add a view in schema B that points to C instead of referencing directly the table and I've had to add the metadata twice, once for schema B and once for schema C.
    If I put the metadata in just one of the two schemas I get the following errors.
    08/11/21 13:58:57 ERROR [oracle.sdovis.ThemeTable] cannot find entry in ALL_SDO_GEOM_METADATA table for theme: AMBITOS_REST

    ORA-13203: failed to read USER_SDO_GEOM_METADATA view
    It's not a big deal but I'd like to know if anyone else has has similar problems.

    Hi Lew,
    if you are using a recent version (10.1.3.1 or later) there is no need to use a view and to create the metadata in both schemas.
    You need to grant selection on tables between the schemas.
    You can try the following. Assume you have the MVDEMO schema (from MapViewer kit) and SCOTT schema.
    1) grant select on MVDEMO Counties table to SCOTT
    SQL> grant select on counties to scott;
    2) Now you are ready to create a predefined theme in schema SCOTT using the MVDEMO Counties table.
    - Open MapBuilder and loads the SCOTT schema.
    - On the Data navigator (bottom left tree), go to Geometry tables and you should see the MVDEMO node and the COUNTIES node inside it.
    - Start a wizard to create a geometry theme based on this Counties table.
    - At the end you should see that the base table name is MVDEMO.COUNTIES. Therefore MapViewer will use the metadata in MVDEMO schema and there is no need to replicate it in SCOTT schema.

  • MAPVIEWER RECEIVING ORA-00942 Table or View does not exist ERROR

    I've created a new 10g instance that will store spatial data almost exclusively. SDO Version 10.1.0.2.0. Using an ESRI product (shp2sde), I have inserted a shape file into the database so that it will accessible through ArcSDE or Oracle Spatial, then created the spatial index. The information appears correct in the USER_SDO_GEOM_METADATA table. The spatial layers are accessible via all ESRI products but when I use our Mapviewer JSP application, it encounters an ORA-00942 Table or View Not Found error. The same procedures to insert data were used in a 9i database and a previous 10g database (built from the same CDs as this instance) without a problem. It looks like there is a permissions problem but cannot put my finger on it. The table is owned by a user AREAOFINTEREST and the Mapviewer datasource is connecting as AREAOFINTEREST.

    What are the datasource and theme definitions in your jsp?
    Could you also post the full error stack that should be in the mapviewer log file.

  • How to use container's data source as mapviewer data source?

    Hi,
    I want to take advantage of connection pooling and hence was trying to create a mapviewer datasource from J2EE container.
    When I use the J2EE ds as the Mapviewer datasource in the Mapviewer admin page, it wouldn't work.
    Rest of the applications deployed on the OC4J container which makes use of the same J2EE ds works fine.
    I referred to the article below to configure the datasource(not the permanent stuff), but it didnt work.
    http://www.oracle.com/technology/products/mapviewer/htdocs/faq_1012/mvfaq_1012.html#oc4jds
    Any help is much appreciated.
    Cheers,
    Sumanth

    I am running mapviewer application with my dynamic datasource created out of JDBC URL. All the shipped-in demos and my own mapviewer application works fine with this.
    The trouble is when my application runs it creates too many database connections (my observation is a connection each for a theme).
    There are about 16 themes and the application opens up 16 connections (I have monitored the statements for each of these connections and they are for the individual themes). Although we could increase the max connections of our database, ideally we would like to make use of less connections.
    An efficient way of solving this would be to create the dynamic datasource out of J2EE data source rather than JDBC URL.
    So, when I define a dynamic datasource through the mapviewer admin page from an existing J2EE data source, it creates a datasource with JDBC URL as "thin:@:1521:" and schema user as "scott", both of which are incorrect. Referred to the article below to solve this but with no luck
    http://www.oracle.com/technology/products/mapviewer/htdocs/faq_1012/mvfaq_1012.html#oc4jds
    Sorry if I sound stupid with this elementary question. Would appreciate any help.

    After importing the table from data base .
    data type of one coumn showing unknown .but actuall its data type is sdo_geometry in data base .
    whe i click view data ,data is not coming for particular that unknown data type.
    what is compatibility data type of bi admin.
    thanks in advance

    We opened an SR with Oracle (3-8366783331).
    They found that there were some missing configurations.
    The types MV_STRINGLIST, MV_NUMBERLIST and MV_DATELIST are not created in the schema used in the datasource
    Solution
    Create the types as the user connected to the Mapviewer Datasource
    conn / as sysdba
    grant create type to user;
    conn user/password
    CREATE or REPLACE type MV_STRINGLIST as TABLE of VARCHAR2(1000);
    CREATE or REPLACE type MV_NUMBERLIST as TABLE of NUMBER;
    CREATE or REPLACE type MV_DATELIST as TABLE of DATE;

  • USER_SDO_GEOM_METADATA for tables the user does not own

    Hi
    We have a corporate GIS database that holds all our spatial data in one schema. I have created another user that has readonly (RO) access to those tables.
    I am trying to create a Mapviewer datasource that will connect my RO user and query the spatial data in the other schema. However when I run the map defintion tools it tells me that 'there is no accessible table that have one or more sdo_gemotery columns in user_sdo_geom_metadata'.
    Does this mean I have to insert entries for my RO user into USER_SDO_GEOM_METADATA even though it does not own those tables?
    Any advise appriciated.
    Chris

    Yes this is necessary in order to work around a bug in MapViewer (which will be fixed in a future release).
    For instance, this is the entry in SCOTT's user_sdo_geom_metadata for the table CITIES owned by MVDEMO:
    table_name column_name diminfo srid
    MVDEMO.CITIES     LOCATION     ...     8265
    when creating a theme in SCOTT's user_sdo_themes, simply use 'MVDEMO.CITIES' as the table name and you should be all set.

  • STATE_ADMIN if Multipool fails

    If one member of a failover jdbc datasource multipool fails at startup, all applications deployed to the Weblogic instance have STATE_ADMIN mode and cannot be accessed. This is true even for application which do not access a DB at all. This worked well on Weblogic 8.1, but not on 9.2 (MP1).
    Two Oracle database instances are used, whereas the secundary DB is always locked and only opened if the primary DB fails; before opening the secundary DB, the archive log from the primary DB is read by the secundary DB and then the DB user is unlocked. For both DBs a connection pool is configured which are a member of the multipool.
    We use a weblogic cluster with one admin and four managed servers.
    Is this the normal behaviour? How avoid this problem? Any ideas?
    A failover multipool is nearly worthless, if always all DB instances of the multipool have to be accessable.
    Peter

    The answer to my question:
    Change
    - the driver classes from weblogic.jdbcx.oracle.OracleDataSource to oracle.jdbc.driver.OracleDriver
    - the attribute global-transactions-protocol from TwoPhaseCommit to None

  • Add gridlink datasource to Multi Datasource for failover in weblogic

    We have a RAC installation for which I have configured a Gridlink datasource. Also we have a single node DB which is used as a failover database in case RAC is down.
    Now I want to configure a Multi Datasource so that I can add the Gridlink datasource as well as the Generic Datasource in the Multi Datasource and configure it for failover. But when I create the Multi Datasource, I do not see the option to add Gridlink datasource to Multidatasource.
    Can you please suggest what can be done to add the gridlink datasource to multidatasource? If this is not possible, then how can the Generic single node data source be configured as a failover datasource in case the Gridlink Datasource is down.
    Thanks in advance

    What is the problem you are trying to address? Is the issue the availability/non-availability of your RAC database? It may make sense to focus on this first.
    The normal use case for Multi Data Source is failover or load balancing between nodes of a highly available database, such as RAC which keeps data synchronised.
    I am not sure if using a Multi Data Source across Oracle RAC and a non RAC database is supported. If the intention is to provide a HA solution, you will need to have a data synchronisation solution as well. As this is what Oracle RAC does, we come back to my opening question.........
    I assume that Multi Data Sources cannot include Gridlink and non-Gridlink sources for these reasons and also because Gridlink is intended as a replacement for Multi Data Sources, providing better failover, load balancing and performance.
    Hope this is helpful

  • MapViewer add datasource by admin request - problem

    Hello. Sorry for my english. I am from Russia.
    Please suggest me.
    I try to create datasource by admin request, but receive that error:
    <oms_error>Access denied for this operation!</oms_error>
    What does it mean?
    that is request

    If you are using MApViewer 10g (e.g. 10.1.3) this has to be done from the Admin pages once you've logged in as an oc4jadmin.
    To do this programmaticaly see LJ's post elsewhere in this forum on how to do this in Java. That was for clearing the map cache but the same logic applies here.

  • Multiple datasources for Mapviewer WMS

    Hello,
    I have set up a WMS server using mapviewer. I have data sources "prod" and "pub", one is default configured like this in the WMS configuration:
    <wms_config host="myhost" port="8080"
                  protocol="http" default_datasource="wms"
                  public_datasources="prod,pub">
    The problem I am facing is when I am trying to get layers from the  "pub" datasource. Most of the applications I am using throws me the following errors:
    "The WMS server returned no data from the GetMap request" , "Layer NotDefined" , "Invalid Layer requested" or this other one from QGIS:

    I tried to add the DATAOURCE Mapviewer parameter but I still get these same errors.
    When I switch "pub" from public_datasources to default_datasource everything works fine. It seems that I can get layers only from the default datasource. The problem is that I use several database intances and I relly need to have all datasources working.
    Could you help me to know if I'm using it the wrong way or if it is a known bug ?
    Thank you

    Hi Sachin,
    The basi answer is yes.  The other infoobjects will be empty if you load in two seperate update rules.
    Remember one basic rule about cubes: you cannot change (in general) records in a cube that you have loaded previously. 
    But this does not mean the behaviour you want in queries is not correct.
    Suppose you load the following:
    CHAR A, CHAR B, CHAR C, KF 1
    A1               C1      10
              B1     C1       5
    In this case a query on C1 will return 15, although a query for the values of B1 will only return 5.
    hope it helps,
    Tom

    Yes, you are in the wrong forum, but it sounds like you have your environment variable (or registry entry) for ORA_NLS33 pointing at the wrong directory.

  • Non-jdbc datasource for MapViewer

  • Multiple multi-datasource to failover

    We have a heavy architecture in mind:
    Multiple servers would connect to one Oracle RAC in a datacenter. Another Oracle RAC would be set in Standby in another datacenter for Disaster and Recovery.
    If the first datacenter is down, the idea is to automatically promote the RAC of the other datacenter as the Primary, so that the application can switch to connect to the other Oracle RAC.
    On Weblogic 10.3.2, I know it is possible to failover between nodes of a multi datasource.
    However, is it possible to failover from one multi-datasource (pointing the the first Oracle RAC) to another one (pointing to the second Oracle RAC) when the first multi datasource is down?
    We do not want to open connections on the second multi-datasouce if the first one is active.
    I hope this is clear...
    Thank you

    But what if, instead, we defined the first Datasource to connect to all the nodes of the first RAC:
    jdbc:oracle:thin:@(DESCRIPTION=
    (ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=*host1*)(PORT=1521))
    (ADDRESS=(PROTOCOL=TCP)(HOST=*host2*)(PORT=1521)))
    (LOAD_BALANCE=yes)
    (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=SID)
    (FAILOVER_MODE=(TYPE=select)(METHOD=basic)(RETRIES=5)(DELAY=2))))
    and the other datasource to connect to all the servers of the second RAC?
    jdbc:oracle:thin:@(DESCRIPTION=
    (ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=*host3*)(PORT=1521))
    (ADDRESS=(PROTOCOL=TCP)(HOST=*host4*)(PORT=1521)))
    (LOAD_BALANCE=yes)
    (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=SID)
    (FAILOVER_MODE=(TYPE=select)(METHOD=basic)(RETRIES=5)(DELAY=2))))
    And to have the multi datasource to have the failover protocol managed between the two datasources.
    Would it be possible?
    Is it what you were mentioning, Ravish Mody?
    Thanks,
    Pierre
