  Compatible Linux RHEL (Linux Red Hat Enterprise Server 6.7) for oracle database 11.2.0.4 with grid Infrastructure.

  Hi all

  We plan to patch Linux Redhat Enterprise Server (6.4 and 6.5) to 6.7.

  I tried Searchin' on support of oracle for the compatibility of the database for Linux patches, but not able to find accurate information.

  can anyone share the ID document or information related to it.

  If OS RHEL 6 update 4 to 6-7 update patch

  (1) is it compatible

  (2) bugs or problems reported

  (3) in addition to the binary link again than the DBA to perform any other

• How to define JDBC Data Sources in Oracle MapViewer for Oracle database 12 c Release 1 (12.1.0.1)

  How to define JDBC Data Sources in Oracle MapViewer for Oracle database Release 1 (12.1.0.1) 12 c?

  Here is my setup in the conf\mapViewerConfig.xml:

  
  

  < name map_data_source = "mvdemo12".

  jdbc_host = "127.0.0.1".

  jdbc_sid = "orcl12c1".

  jdbc_port = '1522 '.

  jdbc_user = "mvdemo".

  jdbc_password = "7OVl2rJ + hOYxG5T3vKJQb + hW4NPgy9EN.

  jdbc_mode = 'thin '.

  number_of_mappers = '3 '.

  allow_jdbc_theme_based_foi = 'true '.

  Editable = "true" / >

  <!--  ****  -->

  But it does not work.

  After use "sqlplus mvdemo / [email protected]:1522 / pdborcl", it connected to the Oracle 12 c database.

  Anyone know it?

  Thank you

  11.1.1.7.1 use the jdbc_sid syntax, i.e.

  as described in the README file, mypdb1.foo.com

  -Sources of native data (no container) MapViewer can now use the service name of database instead of SID. To provide a db service name, you will use the same attribute of jdbc_sid, but specify the name of the service with double slashes in front, as follows:

  jdbc_host = "foo.com"

  jdbc_sid="//mypdb1.foo.com".

  jdbc_port = '1522 '.

  ... ...

  />

  Use a container_ds to the 11.1.1.7.0.

  that is, instead of using

  jdbc_host = "mydbinstance".

  jdbc_sid = "pdborcl12c".

  jdbc_port = '1522 '.

  jdbc_user = "mytestuser".

  jdbc_password = "m2E7T48U3LfRjKwR0YFETQcjNb4gCMLG8/X0KWjO00Q ="

  jdbc_mode = 'thin '.

  number_of_mappers = "6".

  allow_jdbc_theme_based_foi = "false".

  Editable = "false".

  />

  use

  container_ds = "jdbc/db12c.

  number_of_mappers = "6".

  allow_jdbc_theme_based_foi = "false".

  Editable = "false".

  />

  In my case the Glassfish 3.1.2.2 JDBC connection pool definition has been

  Property

  URL jdbc:oracle:thin:@mydbinstance:1522/pdborcl12c.rest_of.service.name

  Uncheck the wrap JDBC objects in advanced Panel, that is, the page properties change JDBC connection advanced pool.

  Add a resource to that newly created JDBC pool

  Use in mapviewerconfig.xml as above

• Model reusable SQL Oracle to create a DDL/DML Scripts for Oracle database

  Hello
  
  
  I have an obligation to set up a model of Oracle SQL to create the Scripts DDL/DML reusable for Oracle databases.
  Only the Oracle DBA will run scripts permissions is not a problem.
  
  The workflow for any DOF is as follows:-
  
  (1) new table
  
  a. check whether the table exists in the views system/admin.
  b. If the table exists then give message "Table exists".
  c. If the table does not exist then run DDL code
  
  (2) add the column
  
  a. check if the column exists for a given table of the system/admin views
  b. If the column exists in the specified table.
  B1. backup table.
  B2. ALTER table alter column
  B3. check data or execute convert dml sauvegardΘ to the new change script.
  c. If the column does not exist
  C1. backup table
  C2. ALTER table add column
  C3. Run dml to populate the column with the default value.
  
  The DML scripts are to populate the base tables with the data required for business operations.
  
  (3) addition of new line
  
  a. check if the line exists by comparing the old values of each column with the new values to be added for the new record.
  b. If there is, to give message line is
  c. If not exists, add the new record.
  
  (4) update existing record (we createtime columns in these tables as well as changes can be tracked)
  
  a. check if the row exists using the primary key.
  b. If there is.
  B1. off the record by using the "active" column of the table
  B2. Add new record with the necessary changes.
  c. If does not exist, add the new record with the necessary changes.
  
  Could you please help with some ideas that can get this done with precision?
  I tried several ways, but I am not able to set up something that meets all the requirements.
  
  Thank you

  If it helps at all. Sometimes we have a requirement for a DDL statement to be rerunable and her only error if something completely unexpected happens.

  It's a little monstrous, but basically, we wrap all DDL in a dynamic statement and capture errors that would indicate that the DDL script has already been run:

  Here's a bit of a model:

  declare
     w_ddl varchar2(32767);
  begin
     begin
        --
        dbms_output.put_line('Creating table TABLE_NAME');
        --
        w_ddl := 'CREATE TABLE MY_SCHEMA.TABLE_NAME
                  ( COLUMN_1     DATE          NOT NULL
                   ,COLUMN_2  VARCHAR2(10)  NOT NULL
                   ,COLUMN_3  DATE
                  )';
         --
        execute immediate w_ddl;
        --
        dbms_output.put_line('Successfully created table TABLE_NAME');
        --
     exception
        when others then
           if sqlcode = -955 then
              dbms_output.put_line('Table Already exists.');
           else
              dbms_output.put_line('creation of table TABLE_NAME failed:');
              dbms_output.put_line(sqlerrm);
              raise;
           end if;
     end;
  
    begin
        --
        dbms_output.put_line('Creating unique primary key constraint for TABLE_NAME');
        --
        w_ddl := 'ALTER TABLE MY_SCHEMA.TABLE_NAME ADD (
                 CONSTRAINT TABLE_NAME
                 PRIMARY KEY
                 (TABLE_NAME_ID) USING INDEX)';
         --
        execute immediate w_ddl;
        --
        dbms_output.put_line('Successfully created primary key on TABLE_NAME_ID');
        --
     exception
        when others then
           if sqlcode = -02264 then
              dbms_output.put_line('constraint already exists.');
           else
              dbms_output.put_line('creation of primary key failed:');
              dbms_output.put_line(sqlerrm);
              raise;
           end if;
     END;

  It works well with our scripts to autmoated and help us when we iterate through development and back in if needed test environments.

  In this way, we can add the DDL statements to the deployment script and run the script again without error to set the database to the State required without having to run the newly created statement only.

  Sometimes this approach translates into a creation followed a statement alter table statement to add a column, but the end result of the script is always the same, and the deployment script can be controlled at source between iterations of development that is without having to restore the ddl changes to test the modified DDL script.

  hope that gives you some ideas.

• The CPU is not powerful enough for Oracle database 11g?

  The CPU is not powerful enough for Oracle database 11g?
  
  I installed the datatase Oracle 11 g on my host by using the default configuration of oracle yesterday. Today, I find some the alert message: "CPU usage is 86,79%, through attention (80) or critical (95) threshold.» The average value of the CPU usage is 80.85% and I have to wait for more than 10 seconds for opening a page of the EM.
  My host is HP workstation xw4200. CPU is 3.4 GHz. No other applications on that host.
  I want to know: what is the main reason for the shortage of CPU resources? Because the database Oracle 11g itself is exhausting CPU or because there are a few configuration issues?

  qkc wrote:
  1 is it true that most of the CPU is exhausted by the EM control tool?

  It's quite possible.

  It is also one of the reasons why we encourage people to drop EM Database Console and switch to EM Grid Control. The burden is then on another server.

  2. why this index has been added in advance by Oracle Corporation? It does not seem that each tool is set up perfectly in advance.

  It was probably not required under ideal conditions, in which it has been designed and tested.

  Why is your environment not identical to the designed conditions that use Oracle? ;-)

• Upgrade of Oracle EBS base 10.2.0.4 for Oracle Database 12 c

  Hi gurus,

  We are in the process of upgrading our EBS Oracle 10g database to 12 c and so below are the steps we took to upgrade the database with dbua 12 c

  We have improved our database 10g of 10.2.0.4 to 10.2.0.5 compatible for the direct 12 c with dbua upgrade

  1 - install the Oracle 12 c software

  2. run the file from Oracle EBS environment that set the ORACLE_HOME and ORACLE_SID, but not ORACLE_BASE for the database that is upgraded

  3 - Go to the ORACLE_HOME\bin 12 c and run. / dbua

  4 - 12 c dbua GUI appeared, but this isn't picking the 10g database in the Source ORACLE_HOME

  What could be the cause and how is - this solve

• DataGuard for oracle database applications...

  Hello world
  
  I got a new task on the protection of data for oracle applications configuration. I did it for the database.

  In my own understanding, data hold is at the level of the database not not at the application level. If you just need to keep your data compared to the level of the database.

• MySql to Oracle DB Migration, creating schema problem

  Hello
  Im a beginner, try to migrate a mysql database in oracle. The mysql db contains a few tables, if im trying to migrate everything manually.
  When filling out the tables a problem im. It's as follows:
  
  Table 1 has a Key (t1_col1, t1_col2, t1_col3) primary Composite.
  Table2 contains a column (t2_col1), which is a reference to Table1 t1_col1 (to make t1_col1 a repository key in the other table must be UNIQUE or PRIMARY, but as we know table can have a unique primary key and the t1_col1 contains redundant data, so cant make UNIQUE either).
  So I tried indexing of the t1_col1 column but it dint seem to work as well, creating table2 it gives "no unique match or primary key for this list of columns.
  ".
  
  I think that MySql is not so strict a lot compared to Oracle, please guide me through this, any workaround (s)?
  This is the MySql schema:
  
  CREATE TABLE "temp". "table1")
  't1_col1' varchar (50) NOT NULL,
  't1_col2' varchar (50) NOT NULL,
  't1_col3' varchar (50) NOT NULL,
  "t1_col4" integer NOT NULL,
  PRIMARY KEY ('t1_col1', 't1_col2', 't1_col3')
  )
  ENGINE type = InnoDB
  CHARACTER SET utf8 COLLATE utf8_general_ci;
  
  
  
  CREATE TABLE "temp". "table2")
  't2_col1' varchar (50) NOT NULL,
  't2_col2' varchar (50) NOT NULL,
  FOREIGN KEY CONSTRAINT 'table2_fk1' 'table2_fk1' ('t2_col1')
  REFERENCES, 'table1' ('t1_col1')
  ON DELETE CASCADE
  ON UPDATE CASCADE
  )
  ENGINE type = InnoDB
  CHARACTER SET utf8 COLLATE utf8_general_ci;
  
  
  Looking forward to the answer.
  
  Kind regards

  If I didn't know that MySQL allows you to declare FK constraints that are non-profit information only and does not apply, I would find this surprisiing really, since the essence of a FK relationship is that the child is identified by the parent.

  In Oracle, you must create a primary key for the substitution on the table1 based on the unique combination of col1, col2 and col3. I would certainly use a sequence for it. Next, you create a unique constraint on col1, col2 and col3 to apply your natural primary key. FK in table2 would be the key to substitution from table1. Something like:

  CREATE TABLE table1 (
     t1_surr_key NUMBER NOT NULL,
     t1_col1 Varchar2(50) NOT NULL,
     t1_col2 Varchar2(50) NOT NULL,
     t1_col3 Varchar2(50) NOT NULL,
     t1_col4 integer NOT NULL)
  
  ALTER TABLE table1 ADD CONSTRAINT table1_pk
     PRIMARY KEY (t1_surr_key);
  
  ALTER TABLE table1 ADD CONSTRAINT table1_uk
     UNIQUE (t1_col1, t1_col2, t1_col3);
  
  CREATE TABLE table2 (
     t2_col1 varchar2(50) NOT NULL,
     t2_col2 varchar2(50) NOT NULL,
     t1_surr_key NUMBER NOT NULL,
  CONSTRAINT table2_fk1 FOREIGN KEY (t1_surr_key)
     REFERENCES table1 (t1_surr_key)
     ON DELETE CASCADE
     ON UPDATE CASCADE)

• Need help for analysis "plan and background events waiting" on the report statspack for oracle database 11.2.0.4 on AIX

  HI: I analyze the STATSPACK report: this is the "volume test" on our UAT server for most of entry or "bind variables".  Our shared pool is well used in oracle.  Recovery of Oracle logs is not configured properly on this server, as in "Top 5 events of waiting", there are 2 for Oder.

  I need to know what other information may be digging from of 'waiting in the foreground events' & ' background waiting events ", and which can help us better understand, in combination of ' Top 5 wait event, that how did the server test /?  It could be overwhelming. wait events, so appreciate useful diagnostic or analyses.  Database is oracle 11.2.0.4 updated from 11.2.0.3 on IBM AIX 64-bit, level 6.x system power

  Hello

  I think that your CPU is overloaded by your stress tests. You have one VCPU with 2 wires (2 LCPU), right? And the load average is greater than one. You have time DB which is not counted in (CPU time + wait events) and which comes no doubt from time spent in the runqueue.

  > Oracle recovery logs is not properly configured on this server, as in "Top 5 events of waiting", there are 2 for oder

  It is an error in statspack for show "log file parallel write here." This moment is historical and is included in 'log file sync '. And I don't think you have to redo misconfiguration. Waiting for 1ms to commit is ok. In OLTP you should have more than one validation in a user interaction so that the user don't worry not about 1 m in batch mode, unless you commit to each row, 1 DC to commit should not increase the total execution time.

  The fact that you have a lot of line lock (enq: TX - line lock conflict) but very little time (on average 97 ms) is probably a sign that testers are running simultaneously a charge affecting the same data. Their set of test data is perhaps too simple and short. An example: when stress tests of an order entry system if you run 1000 concurrent sessions, ordering the same product to the same customer, you can get this kind of symptoms, but the test we unrealistic.

  It's a high activity of 2000 calls per second, 52 transactions per second, user. But you also have low average active sessions, so the report probably covers a period of non-uniform activity, which makes the averages without meaning.

  So note to tell about the events of waiting here. But we don't have any info about 39% of DB time devoted to the CPU which is where something can be improved.

  Kind regards

• VMware Clod Migration boot cd for the database Migration SQL Server

  Hi techies,.

  I have a requirement to migrate one of our physical DB server to the virtual machine, it is very important to business so I thought to go with cold cloning with boot cd, but I could not get this cd bootable anywhere... ! can someone help me on this? and also please suggest me there at - it another way, I can do this task successfully with some fails?

  VMware Converter 5.x has the ability work synchronize to power use this run a p2v migration

  (1) perform a P2v full and when its done and you're ready to cut more

  (2) stop the database service and do a synchronizaion and put the virtual machine online

• link to the oracle for oracle databases

  Hi all
  I want to create link of database from a system to another system.
  can u give me steps to create the db link and the listener and tnsnames for example.
  
  Thank you

  CKPT SALVATION,
  Thanks for the response.i have difficulty assign listener and tnsnames.
  If possible can make u it how to give tnsnames and the listener who do not appear in the documents.

  Thank you
  Srinivas

  Here you will need to check the exact TNS service where you want to connect.

  If you want to create a DB CONNECTION in Server "A" and it should point to server 'B '.

  (1) check the connectivity to the server 'B', as below - make sure that listener runs on the server 'B '.
  $tnsping to_b

  (2) If you can do a ping to the correct host/Sid/Port. Then you should be able to create DB link

  (3) from the database of the server 'A', create DB link

  SQL > CREATE DATABASE LINK CONNECT TO IDENTIFIED BY USING 'to_b ';

  once able to connect, test you the DB LINK
  (4) SQL > select count (*) from

  @db_link;

  HTH.
