6 Managing an OracleAS Metadata Repository

This chapter provides information on managing OracleAS Metadata Repository.

It contains the following topics:

6.1 Frequently Asked Questions About OracleAS Metadata Repository

OracleAS Metadata Repository is an Oracle Database 10g database and can be managed using standard database procedures and tools. However, there are some considerations for managing OracleAS Metadata Repository within the Oracle Application Server environment. This section answers frequently asked questions about managing the Metadata Repository.

6.2 Postinstallation Status of OracleAS Metadata Repository Schemas

Table 6-1 shows the status of Metadata Repository schemas immediately after installation. The table contains the account status and initial password for each schema, depending on whether the Metadata Repository is registered with Oracle Internet Directory.

To unlock an account using SQL*Plus (be sure to set your ORACLE_HOME and ORACLE_SID environment variables before you run these commands):

ORACLE_HOME/bin/sqlplus "SYS/password_for_sys AS SYSDBA"
SQL> ALTER USER schema ACCOUNT UNLOCK;

To lock an account:

ORACLE_HOME/bin/sqlplus "SYS/password_for_sys AS SYSDBA"
SQL> ALTER USER schema ACCOUNT LOCK;

The method for changing passwords varies by schema. Refer to Section 6.4, "Changing OracleAS Metadata Repository Schema Passwords" to determine the proper way to change a password.

6.3 Viewing OracleAS Metadata Repository Schema Passwords

If a Metadata Repository is registered with Oracle Internet Directory, some schema passwords are stored in the directory and you can view them using Oracle Internet Directory tools.

You can view the passwords for the following schemas in Oracle Internet Directory:

B2B ORASSO_PS
BAM ORASSO_PUBLIC
DCM OWF_MGR
DISCOVERER5 PORTAL
DSGATEWAY PORTAL_APP
OCA PORTAL_DEMO
ODS PORTAL_PUBLIC
OEM_REPOSITORY UDDISYS
ORABPEL WCRSYS
ORAOCA_PUBLIC WIRELESS
ORASSO WKPROXY
ORASSO_DS WKSYS
ORASSO_PA

You can view the passwords using the following procedures:

6.3.1 Viewing OracleAS Metadata Repository Schema Passwords using Oracle Directory Manager

To view Metadata Repository schema passwords using Oracle Directory Manager, take the following steps:

  1. Start Oracle Directory Manager:

    • On UNIX, use the following command:

      ORACLE_HOME/bin/oidadmin
      
      
    • On Windows, navigate to Oracle Directory Manager (Start > Programs > Oracle Application Server Oracle_Home > Integrated Management Tools > Oracle Directory Manager.)

  2. Log in to Oracle Directory Manager as the orcladmin user.

  3. In the System Objects frame, expand Entry Management, expand cn=OracleContext, expand cn=Products, expand cn=IAS, expand cn=IAS Infrastructure Databases, and expand orclReferenceName=dbname for the Metadata Repository.

  4. Select the OrclResourceName=schema_name entry for the schema whose password you want to view.

  5. In the Properties tab, you can view the password in the orclpasswordattribute field.

6.3.2 Viewing OracleAS Metadata Repository Schema Passwords using ldapsearch

You can view Metadata Repository schema passwords by using ldapsearch, a command-line tool. The command uses the following format:

ORACLE_HOME/bin/ldapsearch -p oid_port -h oid_hostname -D "cn=orcladmin"
-w orcladmin_password -b "orclresourcename=schema_name,
 orclreferencename=metadata_rep_global_db_name, cn=ias infrastructure databases,
 cn=ias, cn=products, cn=oraclecontext" -s base "objectclass=*"
 orclpasswordattribute

The command returns several lines of output. The password is listed in the following line:

orclpasswordattribute=password

The following example uses the ldapsearch tool to request the ORASSO schema password.

ORACLE_HOME/bin/ldapsearch -p 13060 -h myhost -D "cn=orcladmin"
-w mypassword -b "orclresourcename=ORASSO, 
orclreferencename=orcl.mycompany.com, cn=ias infrastructure databases,
cn=ias, cn=products, cn=oraclecontext" -s base "objectclass=*"
orclpasswordattribute

The command returns the ORASSO schema password, which is Og23NI78 in this example:

OrclResourceName=ORASSO,orclReferenceName=orcl.mycompany.com
cn=IAS Infrastructure Databases,cn=IAS,cn=Products,cn=OracleContext
orclpasswordattribute=Og23NI78

6.4 Changing OracleAS Metadata Repository Schema Passwords

The method for changing schema passwords in the Metadata Repository varies by schema. Some schemas store their passwords in Oracle Internet Directory; you must change their passwords using the Application Server Control Console so that both Oracle Internet Directory and the database are updated. Other schemas do not store their passwords in Oracle Internet Directory; you change their passwords in the database using SQL*Plus. A few schemas require special steps for changing their passwords.

Table 6-2 lists the appropriate method for changing each Metadata Repository schema.

6.4.1 Changing Schema Passwords Using the Application Server Control Console

Some schemas store their passwords in Oracle Internet Directory. You must change their passwords using the Application Server Control Console so the password is updated in both the database and Oracle Internet Directory.

To change a schema password using the Application Server Control Console:

  1. Depending on the schema, navigate to the home page for the middle-tier instance or the Infrastructure. Refer to Table 6-2 to determine which home page to use.

  2. On the home page, click Infrastructure.

  3. On the Infrastructure page, click Change Schema Password.

  4. On the Change Schema Password page, select the schema. Enter the new password in the Password and Confirm Password fields. Click OK.

6.4.2 Changing Schema Passwords Using SQL*Plus

You can change some schema passwords directly in the database using SQL*Plus. To do so, connect to the database as a user with SYSDBA privileges and issue the following command:

SQL> ALTER USER schema identified by new_password;

For example, to change the SCOTT schema password to abc123:

SQL> ALTER USER SCOTT IDENTIFIED BY abc123;

6.4.3 Changing Schema Passwords in Oracle Internet Directory

A few schemas (DCM, B2B, OWF_MGR) require you to manually update the password in the Metadata Repository and in Oracle Internet Directory. Use the following procedure to change these passwords:

  1. Start Oracle Directory Manager:

    • On UNIX, use the following command:

      ORACLE_HOME/bin/oidadmin
      
      
    • On Windows, navigate to Oracle Directory Manager (Start > Programs > Oracle Application Server Oracle_Home > Integrated Management Tools > Oracle Directory Manager.)

  2. Log in to Oracle Directory Manager as the orcladmin user.

  3. In the System Objects frame, expand Entry Management, expand cn=OracleContext, expand cn=Products, expand cn=IAS, expand cn=IAS Infrastructure Databases, and expand orclReferenceName=dbname for the Metadata Repository.

  4. Select the OrclResourceName=schema_name entry for the schema whose password you want to change.

  5. In the Properties tab, update the password in the orclpasswordattribute field.

  6. Click Apply.

6.5 Changing the Character Set of OracleAS Metadata Repository

You can change the character set of the OracleAS Metadata Repository by following the instructions for changing the character set in the database documentation.

Then, take the following steps to configure the middle-tier and infrastructure to work with OracleAS Metadata Repository after its character set has been changed:

  1. Modify the character set of all Database Access Descriptors (DADs) accessing the metadata repository to the new database character set.

    1. Using the Application Server Control Console, navigate to the middle-tier instance home page.

    2. In the System Components section, click HTTP_Server.

    3. On the HTTP_Server home page, click Administration.

    4. On the HTTP_Server Administration page, click PL/SQL Properties. This opens the mod_plsql Services page.

    5. Scroll to the DADs section and click the name of the DAD that you want to configure. This opens the Edit DAD page.

    6. In the NLS Language field, type in a NLS_LANG value whose character set is the same as the new character set for OracleAS Metadata Repository.

    7. Click OK.

    8. Repeat steps e to g for all DADs accessing OracleAS Metadata Repository.

  2. Reconfigure the Oracle Ultra Search index as follows:

    1. Connect to OracleAS Metadata Repository as WKSYS and invoke the following SQL script to reconfigure the default cache character set and index preference:

      (UNIX) ORACLE_HOME/ultrasearch/admin/wk0prefcheck.sql
      (Windows) ORACLE_HOME\ultrasearch\admin\wk0prefcheck.sql
      
      
    2. Connect to OracleAS Metadata Repository as the default user (WKTEST) and invoke the following SQL script:

      (UNIX) ORACLE_HOME/ultrasearch/admin/wk0idxcheck.sql
      (Windows) ORACLE_HOME\ultrasearch\admin\wk0idxcheck.sql
      
      

      The script asks you to enter the instance name (WK_INST). Enter y when prompted to proceed with the change.

      This script reconfigures the instance (in this case, the default instance). It also truncates the Oracle Text index used by Oracle Ultra Search and you must force a recrawl to rebuild the index.

    3. Repeat step b for all Oracle Ultra Search instances that were created before you changed the database character set. Invoke the script as the instance owner, and then force a recrawl of all data sources, if necessary.

  3. If you installed OracleAS Portal, you must make sure that it is configured with the same languages as the OracleAS Infrastructure (which includes OracleAS Metadata Repository) to avoid problems with set language requests sent to OracleAS Single Sign-On. To configure additional languages for OracleAS Portal, you run the ptlang tool.


    See:

    The section "Configuring Language Support" in the Oracle Application Server Portal Configuration Guide for information on the ptlang tool

6.6 Renaming and Relocating OracleAS Metadata Repository Datafiles

When you install OracleAS Metadata Repository, you can choose the location for its datafiles. The default location is ORACLE_HOME/oradata/SID. After installation, you may want to relocate datafiles to a different directory. For example, you may want to move them to a directory on a file system with more space. Or, you may want to move them to a directory on a different disk for performance reasons. Another thing you may want to do is keep the datafiles in the same directory, but rename them.

This section provides a procedure for renaming or relocating datafiles. You can use this procedure on one or more datafiles, and the datafiles may be in multiple tablespaces.

This procedure applies to:

The following example shows how to relocate two datafiles in two different tablespaces, as follows:

Before you start the procedure:

The procedure is as follows:

  1. Verify the location of your datafiles.

    You can verify the location of datafiles in a particular tablespace by querying the data dictionary view DBA_DATA_FILES.

    For example, to query the location of datafiles in the OCATS and DCM tablespaces:

    SQL> SELECT FILE_NAME, BYTES FROM DBA_DATA_FILES
    WHERE TABLESPACE_NAME = 'OCATS' OR TABLESPACE_NAME = 'DCM';
    
    FILE_NAME                                       BYTES
    ---------------------------------------------   ------------
    /infra_home/oradata/orcl/oca.dbf                78643200
    /infra_home/oradata/orcl/dcm.dbf                96993280
    
    
  2. Shut down all middle-tier instances that use OracleAS Metadata Repository.

  3. Stop the Infrastructure that contains OracleAS Metadata Repository, then start an OracleAS Metadata Repository instance and mount the database without opening it, as follows:

    1. Stop the Application Server Control Console and OPMN-managed processes:

      • On UNIX systems:

        ORACLE_HOME/bin/emctl stop iasconsole
        ORACLE_HOME/opmn/bin/opmnctl stopall
        
        
      • On Windows systems:

        ORACLE_HOME\bin\emctl stop iasconsole
        ORACLE_HOME\opmn\bin\opmnctl stopall
        
        
    2. Leave the Metadata Repository listener running.

    3. Stop the OracleAS Metadata Repository instance (make sure the ORACLE_HOME environment variable is set):

      sqlplus /nolog
      SQL> connect SYS as SYSDBA
      SQL> SHUTDOWN
      
      
    4. Start an OracleAS Metadata Repository instance and mount the database without opening it:

      SQL> STARTUP MOUNT
      
      
  4. Move the datafiles to their new location using the operating system. For example:

    • On UNIX systems:

      mv /infra_home/oradata/orcl/oca.dbf /new_directory/oca.dbf
      mv /infra_home/oradata/orcl/dcm.dbf /new_directory/dcm.dbf
      
      
    • On Windows systems:

      rename C:\infra_home\oradata\orcl\oca.dbf D:\new_directory\oca.dbf
      rename C:\infra_home\oradata\orcl\dcm.dbf D:\new_directory\dcm.dbf
      

    Note:

    You can execute an operating system command to copy a file by using the SQL*Plus HOST command.

  5. Use ALTER DATABASE to rename the file pointers in the database's control file:

    SQL> ALTER DATABASE
          RENAME FILE          '/infra_home/oradata/orcl/oca.dbf',
                               '/infra_home/oradata/orcl/dcm.dbf'
          TO                   '/new_directory/oca.dbf',
                               '/new_directory/dcm.dbf';
    
    

    The new files must already exist; this statement does not create the files. Always provide complete filenames (including their full paths) to properly identify the old and new datafiles. In particular, specify the old datafile name exactly as it appears in the DBA_DATA_FILES view of the data dictionary.

  6. Shut down OracleAS Metadata Repository, then perform a normal startup of the Infrastructure:

    1. Leave the OracleAS Metadata Repository listener running.

    2. Shut down OracleAS Metadata Repository:

      SQL> SHUTDOWN
      
      
    3. Start OracleAS Metadata Repository:

      SQL> STARTUP
      
      
    4. Start OPMN-managed processes and the Application Server Control Console:

      • On UNIX systems:

        ORACLE_HOME/opmn/bin/opmnctl startall
        ORACLE_HOME/bin/emctl start iasconsole
        
        
      • On Windows systems:

        ORACLE_HOME\opmn\bin\opmnctl startall
        ORACLE_HOME\bin\emctl start iasconsole
        
        
  7. Start the middle-tier instances that use the Infrastructure.

  8. Verify the new location of your datafiles.

    SQL> SELECT FILE_NAME, BYTES FROM DBA_DATA_FILES
    WHERE TABLESPACE_NAME = 'OCATS' OR TABLESPACE_NAME = 'DCM';
    
    FILE_NAME                                     BYTES
    --------------------------------------------- ---------------
    /new_directory/oca.dbf                        78643200
    /new_directory/dcm.dbf                        96993280
    
    
  9. Perform a complete cold backup of OracleAS Metadata Repository. After making any structural changes to a database, always perform an immediate and complete backup.
