• two ways to get the freespace in an oracle database show different values

  Hello

  I tried to get the freespace in a tablespace with different methods.

  R: first method

  1 Select tablespace_name, sum (bytes) /(1024*1024) MB dba_data_files group by tablespace_name;   # to get the totalspace (divided) of storage space

  TBS1 13312 MB

  2. Select tablespace_name, sum (bytes) /(1024*1024) dba_segments MB group by tablespace_name;   # to get used space in the tablespace

  TBS1 13231,625 MB

  3. calculate the free space: totalspace - used space = free space

  13312 - 13231.625 = 80,375 MB of space in the tablespace TBS1

  B: second method

  1. Select tablespace_name, sum (bytes) /(1024*1024) MB dba_free_space group by tablespace_name;  # to get the free space in the tablespace

  TBS1 3888,25 MB

• What are the ways to access a remote database in a database completely different-schema - stored procedure?

  My source data in the remote database schema (say C3.case). And I am trying to insert data of this CASE table in my database table (for example SIMS.case) I use the stored procedure to load the data.

  I was going through the documentation and I thought that the creation of MV is not possible in this case is the source table in the remote database schema. Is this correct?

  or create a link DB is the only option available to access the remote database schema table.

  Thank you.

  My apologies for the bad conventions help. I meant remote schema.

  the required data and the destination table, the two are in oracle, but in totally different schemas.

  Yes, you said a table is in a scheme called C3, and the other is in a schema called SIMS.  Are these schemas in the same database or in different databases?

  If they are in the same database, then you do not have a database link.  Or the other schema can reference tables in the other qualifying names correctly, for example

  SELECT *.

  OF C3. case_studies

  ...

  assuming that the right privileges have been granted.

  If the schemas are in different databases, a database link is the best way to access data in a database in a different database.

  Without a database link, you will probably use some kind of use outside the database to write the data to a database, the file if necessary, transport and read in other databases.  DataPump files of images or CSV files, as Paulzip said in answer to #1, could be used for this.

• Planning by connecting two different vesion of the oracle database

  Hi friends,
  
  I'm an Oracle application technical developer. I know to plan for concurrent programs in EBS. But my current project needs a migration of the EBS from another version of database data. Our Production database is oracle 9i (EBS). We are doing a project on a BI tool. Tool BI must advanced version 11g (just 11 g db, no EBS). Now my work moves some of the inventory and sales details for the 11g from 9i. I'm running a query of 9i, export the data set such as file delimited by file and using sql loader to load the data into your table looks 11 g. This process takes a lot of time like 4-5 hours daily.
  
  
  Y at - it an idea that I can do the automation or the planning of the above process. I checked all planning forums. Most of them face the automation with the same database. Please help me in suggesting an idea
  
  Thank you
  Vimal...

  First thought is that you should get at least to the patch terminal which is 9.2.0.8.

  But to answer your own question... Why write to a file? Create a database connection and select in the stand-alone database.

  If you had a version that is fully supported in the database, I would recommend replication with the watercourse or of change data Capture.

  Other alternatives such as external tables, too, are not available to you that you are working with an antique. An upgrade to 11g is really appropriate for this and many other reasons.

• NoSQL Oracle database charger with EE last does not work

  I am unable to run the NoSQL Oracle database loader to load data at: http://www.oracle.com/technetwork/products/nosqldb/documentation/index.html which is included in the documentation with the latest download of Oracle NoSQL. I downloaded the EA on my Unix machine and have the JAVA version:
  race of '1.7.0_17 '.
  
  (I'm under KVlite. I was able to run the Hello Big World Data example).
  
  This is step 6 in the Readme.txt file that I can't run.6. To load the contents of the tweeter to the Bank to run this command:

In addition, the sample in the README.txt step 6 also does not align with the documentation available in the java file < tagname1 > < tagname2 > use. I am able to run step 5 to see the use of arguments.
  
  I'm out of options on how to solve this problem and would appreciate some advice asap for a demo that I build. I certainly need to have this job so I can load my own cvs (with a few tweaks to the arguments). I'm beginner JAVA Programmer so explanations with examples are greatly useful.

  The file README says to the kvclient and the onlh.jar - cp, not onlh.jar in cp and the kvclient as the - pot arg. If you move the kvclient.jar to the - CP

  only.jar:.../kvclient.jar - cp

  It will work.

• RAC with Oracle VM and Windows Server

  Hi all,
  
  We want to implement the system with Oracle database 11g or 10g 64 bit (CARS) on the OS of Microsoft Server 2008/2003. We do not have enough licenses for all the hearts, and we want to find a way to implement the RAC database with existing licenses.
  
  Is this a good solution to use virtualization, as Oracle VM?
  How much is safe to use virtualization?
  Can we do Oracle Real Application Clusters (RAC) environments Oracle VM with Windows Server 2008 64-bit (or 2003 Server) operating system and use hard partition?
  Is it better to invest in licenses or try with Oracle VM?
  
  
  Oracle VM can be configured so that it is recognized as a difficult score.
  Hard partitions allow customers of one license these CPU used by the partition instead of license all the processors on the physical server.

• With regard to the migration of the Oracle database to MS SQL

  Hi all
  
  In my application, oracle is the existing database. We need to migrate from Oracle database to MS SQL.
  We need procedure is as below
  1 export data from Oracle and keep it in a file. (.dmp)
  2 import data from MS SQL in the oracle export file.
  
  and vice versa from MS SQL to Oracle.
  
  My question is - it is possible to import the .bmp (oracle export data) in MS SQL.
  
  Please clarify for me.

  There are two options to get the data from Oracle to MS SQL.
  The simplest is to create a linked in MS SQL to Oracle server and copy the data with a query like select * in oracle.schema.table my_mssqlTable; via the linked server.
  Some data types will not be supported.
  That's an instant copy.

  If you need a fence at real-time replication, you can use replication MS (I would not recommend because it creates triggers on the Oracle tables), or you can use GoldenGate or DataCurrents or other replication products.

• Turning to Oracle RAC to the only Oracle database

  Hi all

  We are responsible for "make a copy" of Oracle RAC database a customer and our plan is to finish with the FCAC and allows you to host a new unique Oracle database. Very few of us familiar with CARS and looking for suggestions on how to do it (without affecting the source JAR).

  Can take a full expdb of the source database and simply use impdp to import into the standalone database server?

  Comments/suggestions appreciated.

  Thanks in advance.

  Can take a full expdb of the source database and simply use impdp to import into the standalone database server?

  It is an option. Data pump does not care if the source and/or destination is CARS or a mix. If the database is too large, it can take a lot of time to complete.

  Another option is to use the DOUBLE of RMAN feature. And another option is to restore the database from a backup.

  See you soon,.

• Where should you install Oracle database and grid Infrastructure in order to comply with OFA?

  I downloaded two files compressed to the Oracle database installation, and both zipped install files for the grid Infrastructure.  The book I'm following for installation is said to use a directory of the database and a directory for the grid Infrastructure, but it does not explain where they should be located in OFA.  Probably they should both close up somewhere in the same Base of Oracle (since all Oracle related on a single file system should go in the same basis, according to my understanding), but it is not clear where they need to be installed over the other.  For example, the grid Infrastructure is a separate product that gets its own Oracle Home?  Anyone can shed some light on this process?

  Also, does it matter where the zipped files are uncompressed?  For example, use one of these files after the installation process, or OFA only cares location after installation?

  Yes, they go in separate oracle_home.  This should be explained in the respective Setup Guide.  This will be a CAR or a standalone ASM?  I have

  It does not matter where you unzip the installation files.  They are only used for the installation.

• Oracle Database 11 g RAC 2: role of the Public, private, virtual, and SCAN IPs.

  Hi Experts,
  
  1 can you please let me know why we need to set up under IP addresses for the RAC configuration and what is the role that each plays?
  
  
  -Public
  -Private

  Concerning

  Hello

  859875 wrote:
  Hi Experts,

  1 can you please let me know why we need to set up under IP addresses for the RAC configuration and what is the role that each plays?

  -Public

  Configured before installation for each node and can be resolved at this node before installing.
  Role:
  Enable Virtual/SCAN configuration/communication between the nodes in the cluster. Do not start the Clusterware without public IP Interface/address.
  Virtual/SCAN will work as an alias IP on the public Interface on the Public network.

  -Private or interconnection

  Configured before installation, but on a separate private network, with its own subnet, which is not resolved except by other nodes in the cluster member
  Role:
  Clusterware uses for cluster synchronization (network heartbeat) interconnection and communication of demon among the nodes in the cluster.
  RAC uses the interconnect for cache fusion (UDP) and inter-process communication (TCP).
  Cache Fusion is the remote Oracle buffers, shared memory mapping between the caches of the members of the cluster nodes.

  -Virtual

  Configured before installation for each node, but not currently in use. IP, VIP and treats public SCAN addresses than any other addresses on the same subnet.
  Role:
  The goal is the availability of the applications. If add or remove nodes as your remove VIP client config (with SCAN, it is not necessary)
  When a node fails, the VIP associated with it is automatically failed over to another node.
  Without using VIPs or FAN, clients connected to a node who died often wait a TCP timeout (which can be up to 10 min) before getting an error.
  So, you don't have really a good HA solution without using VIPs and FAN. The best way to use the FAN is to use a client integrated with fast connection failover (FCF) such as JDBC, OCI, or ODP.NET.

  -SCAN

  Three static IP addresses that are configured on the server (DNS) domain names prior to installation so that the three IP addresses are associated with the name provided as the SCAN, and all three addresses are returned in random order by the DNS to the applicant
  Configured prior to installation in the DNS to resolve the addresses that are not currently in use. Addresses on the same subnet than all other IP addresses, addresses VIP and public SCAN
  Role:
  The goal is the availability of the applications before clients establish communication with CARS and make the whole of the Cluster completely transparent.
  IP SCANNER is a new 'layer' (oracle) with high availability network that allows to modify the characteristics of your cluster (IE add/remove nodes) without having to change the configuration in their concept of customers 'grid '.
  >

  2. What is the relationship between IP SCAN and virtual IPs?

  IP SCANNER is used to receive new connection requests and redirects to the VIP IP.
  The virtual IP address sets and allow failover of connections after connection is established.

  When the client requests a connection, Oracle Client 11 GR 2 find for IP addresses and create a list of all IP SCAN available for this host-scan, the first attempt to connect to RAC uses one of the available SCAN IP addresses.
  The listener ANALYSIS will receive this connection and re - direct to one of the available using LOCAL_LISTENER nodes from that time the connection is made by using the virtual IP (VIP).

  All SCAN/VIP must be resolved by the DNS.

  The customer knows that there is only the Hostname SCAN, which is configured in the connection string.
  Once the connection is requested Oracle Clusterware redirects the connection to one of the VIP host name must be resolved by the DNS.
