Creating Oracle Users and Tablespaces

SEI provides SQL scripts to create dedicated Oracle users and tablespaces. You must run the scripts BEFORE installing SEI. This step is required as of version 2022 R1.3.

Note

These scripts must be run with a user with administrative permissions on the server.

Follow these general steps:

Step 1: Revoke an existing user's permissions

Step 2: Create the SEI user and schema

Step 3: Create the BILicense user and schema

Step 4: Create the SEICube user

Step 5: Install the SEI packages

Additional scenarios:

You can add space to the Oracle database as needed.

When uninstalling SEI, you can remove the Oracle users.

Step 1: Revoke an existing user's permissions

If an Oracle user is already used in your SEI environment, you must revoke this user's permissions before proceeding.

  • Run the 0_RevokePermissions.sql script.

    Set the SEI_USER parameter to SEI.

END;

Step 2: Create the SEI user and schema

  • Run the 1_ConfigDB.sql script.

    Configure the parameters as follows:

    1. The SEI_USER parameter must be set to SEI.

    2. The SEI_TABLE_SPACE parameter should be set to SEI but you can change it another name.

    3. The SEI_TMP_TABLE_SPACE parameter should be set to SEI_TMP but you can change it another name.

    4. Set the other parameters as needed.

END;

Step 3: Create the BILicense user and schema

  • Run the 1_ConfigDB.sql script again.

    Configure the parameters as follows:

    1. The SEI_USER parameter must be set to BILicense.

    2. The SEI_TABLE_SPACE parameter should be set to BILicense but you can change it another name.

    3. The SEI_TMP_TABLE_SPACE parameter should be set to BILicense_TMP but you can change it another name.

    4. Set the other parameters as needed.

Step 4: Create the SEICube user

This user will have access to the cube data; this includes access to all schemas (users). You can exclude access for specific tables.

  • Run the 2_DataDB.sql script.

    Configure the parameters as needed, as described in the script instructions. Make sure to provide the access permissions using these parameters:

    • SCHEMA_LIST

    • EXCLUSION_TB_LIST

    • EXCLUSION_VW_LIST

Copy 
/* Script to create users for SEI Cube.
** 
** # Description
** The purpose of this script is to create an user specific for the SEI application.
** The script will create an Oracle user with an associated TableSpace (or can use an existing one)
** The script will also give some permissions on other schemas (users)
** 
** # Permissions
** The SEI_SEED user will have all rights on his own schema
** The SEI_SEED user will have the right to read all tables from the specified schema in the variable `SCHEMA_LIST`
** The SEI_SEED user will have the right to read all views from the specified schema in the variable `SCHEMA_LIST`
** The SEI_SEED user will have the right to create any trigger across the database
** It will be possible to specify some exclusions tables/views to not give access, see more info in the How to use it section
** This script will remove all existing permissions on the existing user
** 
** # How to use it
** - The script needs to be run from a user with administrative permissions on the server
** - Fill the variables after the comment `Change the values`
**   * SEI_CUSTOM_USER: Name of the SEI Cube user
**   * SEI_CUSTOM_USER_PWD: Password for the user
**   * SEI_CUSTOM_TABLE_SPACE: Name of the main table space for the user
**   * SEI_CUSTOM_TABLE_SPACE_LOG: Enable the logging for the main table space
**   * SEI_CUSTOM_TABLE_SPACE_COMP: Enable the compression for the main table space (Compression has to be enabled server wide)
**   * SEI_CUSTOM_TMP_TABLE_SPACE: Name of the temporary table space
**   * ENABLE_LOGING: Enable the script to print some logs
**   * REVOKE_EXIST_PERM: If the user already exists, define if we want to remove the permissions already granted
**
**   The following parameters are for the permissions
**   * SCHEMA_LIST: List of the schemas (users) tables/views that our user will be able to READ (SELECT) only
**   * EXCLUSION_TB_LIST: List of the tables to exclude for the grant select. Format is "SCHEMA"."TABLE"
**   * EXCLUSION_VW_LIST: List of the views to exclude for the grant select. Format is "SCHEMA"."VIEW"
** - Run the script
**
** # Things to know
** !!! In Oracle, to give the READ access on another schema, we need to do it table by table.
**     => By doing so the grants are point in time and if new tables are added in the future, the script will need to be re-run (it will only update the table grants).
** !!! In Oracle, to give the CREATE TABLE/TRIGGER permission on another schema, the user needs to have a server wide permission so it can create them in amy schema.

Step 5: Install the SEI packages

After creating the Oracle users, you need to run the SEI executables to create the Oracle tables.

  1. Perform the steps to install the License Server.

  2. Perform the steps to install the Central Point.

  3. Perform the steps to install the SEI application (basic or advanced installation).

Additional Scenarios

Adding space to the Oracle database

If you need to add additional space to a table, you can run the script below to add 32 GB of space.

  1. Run the 3_AddNewDataFile.sql script.

    Set these parameters as described in the script instructions:

    • TABLE_SPACE

    • DATA_FILE_NAME

    • ENABLE_LOGING

Copy 
/* Script to add a new datafile to an existing table space.
** 
** # Description
** The purpose of this script is to add a new datafile to a table space to avoid storage issue.
** 
** # How to use it
** - The script needs to be run from a user with administrative permissions on the server
** - Fill the variables after the comment `Change the values`
**   * TABLE_SPACE: Name of the table space to update
**   * DATA_FILE_NAME: Name of the data file to add
**   * ENABLE_LOGING: Enable the script to print some logs
** - Run the script
**
** # Things to know
** !!! You can change the size, maxsize, etc. directly in the script to accomodate your need

Additional Oracle Information

Please see the sections below for additional information about Oracle:

  • SID: Oracle System ID. It uniquely identifies a database (for example: ORCL).

  • User: In Oracle, users and schemas are essentially the same thing. A user is the account you use to connect to a database, and a schema is the set of objects (tables, views, etc.) that belong to that account.

  • Tablespace: An Oracle database consists of one or more logical storage units called tablespaces, which collectively store all of the database's data. Each tablespace consists of one or more files called datafiles, which are physical structures that conform to the operating system on which Oracle is running.

    Note  

    SEI supports Oracle tablespace functionalities such as DEFAULT ROW STORE COMPRESS ADVANCED. However, many Oracle tablespace functionalities (including the one previously mentioned) are additional features that must be purchased separately from Oracle. Please contact your Oracle DBA if you would like to learn more about purchasing licenses for additional tablespace functionalities.

  • Temp Tablespace: A temporary tablespace, as its name implies, stores the temporary data that only exists during the database session. Oracle uses temporary tablespaces to improve the concurrency of multiple sort operations which do not fit in memory. The TEMP tablespace can be shared by multiple users.

  • Datafile: Datafiles are physical files of the operating system that store the data of all logical structures in the database. They must be explicitly created for each tablespace. Oracle assigns each datafile two file numbers, an absolute file number and a relative file number, that are used to uniquely identify it. Multiple datafiles can be added to the same tablespace (regular or temp).

  • Block Size: Size of the block for the data. The size of the block can be different by tablespace but it is usually the same. The size of the block will have a direct impact on the maximum size of the datafile.

  • Block size: The default block size is often 8 Kb so the datafile that can have a maximum of 32 GB.

    To get the current block size of the database, run the following SQL command:

    select value from v$parameter where name = 'db_block_size';

    Block size Maximum datafile size Maximum database size
    2 KB 8 GB 512 TB
    4 KB 16 GB 1 PB
    8 KB 32 GB 2 PB
    16 KB 64 GB 4 PB
    32 KB 128 GB 8 PB

  • Tablespace and datafile: By default, the tablespace contains only one data file. Based on the block size, the default size of a tablespace will only be 32 GB. You need to add more datafiles to a tablespace to store more data (regular or temp tablespace). The maximum number of datafiles that can be added is 65 536 files by database, hence the maximum database size mentioned above (for example: 32 GB x 65 536 = 2 PB). The maximum number of datafiles in a tablespace is 1022 (32 TB for an 8 Kb block size).

    To add more datafiles to a tablespace, run the following SQL command (adjust this command with your own name and desired sizes):

    ALTER TABLESPACE YOUR_TABLE_SPACE ADD DATAFILE YOURNAME.DBF' size 1024m autoextend on maxsize 32767m;

    To get the list of datafiles attached to a tablespace, run the following SQL command:

    SELECT TABLESPACE_NAME,FILE_NAME From DBA_DATA_FILES;

  • Temp tablespace: The temp tablespace can grow quite big once OLAP Manager has loaded the data (full load). However, the used space remains stable for subsequent loads because it will not be allocated anymore.

    Oracle uses temporary tablespaces to improve the concurrency of multiple sort operations that do not fit in memory.

    To see the space allocation of a temporary tablespace, run the following command:

    SELECT * FROM dba_temp_free_space;

    To add more datafiles to an existing tablespace, run the following SQL (adjust this command with your own name and desired sizes):

    ALTER TABLESPACE YOUR_TABLE_SPACE ADD TEMPFILE 'YOURNAME.DBF' size 1024m autoextend on maxsize 32767m ;

  • Logging: In Oracle logging is activated by default on tablespace creation. In the case of the SEI data warehouse, logging is not required because we simply reload the data warehouse instead of using the undo/redo feature. Since logging has a direct impact on the temp tablespace size, it is recommended to deactivate it whenever possible.

    To create a new tablespace without logging, run this command:

    create tablespace your_table_space datafile 'your_name.DBF' size 1024m autoextend on maxsize 32767m NOLOGGING;

    To remove logging for an existing tablespace:

    ALTER TABLESPACE SEICUBE3 NOLOGGING;

  • Compression: There are multiple ways of compressing data in Oracle, but the one we are describing here for SEI is Advanced Row Compression. Advanced Row Compression has many benefits. One significant advantage is Oracle’s ability to read compressed blocks (data and indexes) directly in memory, without uncompressing the blocks. This improves performance thanks to the reduction in I/O, and the reduction in system calls related to the I/O operations. Furthermore, the buffer cache becomes more efficient by storing data without having to add memory.

    To create a new tablespace with compression and without logging, run this command:

    create tablespace your_table_space datafile 'your_name.DBF' size 1024m autoextend on maxsize 32767m DEFAULT ROW STORE COMPRESS ADVANCED NOLOGGING;

    The table below describes a logging and compression test on a cube where the source database had more than 190 million rows. The generated master slice generated resulted in 111 million rows and 3 other slices were over 94 million rows. All scenarios clearly show that logging must be deactivated. It is strongly recommended to use compression since the time to load was not much different and the storage was greatly reduced.

  • User and access: Users are created with no access to SEI by default. You need to create a specific SEI user in the datasource configuration to avoid tablespace limitations.

    To create a user and attach the created tablespace, run this command:

    CREATE USER YOUR_USER IDENTIFIED BY YOUR_PASSWORD DEFAULT TABLESPACE YOUR_TABLESPACE

    TEMPORARY TABLESPACE YOUR_TEMP_TABLESPACE_TMP QUOTA UNLIMITED ON YOUR_TABLESPACE;

    After creating the SEI user, you need to grant the following minimum access to that user:

    GRANT create procedure, create session, create table, connect,

    create type, create view, create synonym, create trigger, resource TO YOUR_USER;

    Note  

    For any Oracle datasource the SEI user must be put as custom schema in the data source definition. This will allow the tracking table or custom objects to be created in this specific user instead of the source. Triggers are the only exception to this rule.

    You also need to grant the SEI user access to all Oracle users (databases) that you will want to read as a source. The level of access will depend on what you want to do (read only, create OLAP Cube, write back, etc.).

    To give the SEI user access to a source, run this command (change SOURCE_USER and YOUR_USER):

    begin

    for x in ( SELECT TABLE_NAME FROM DBA_TABLES WHERE OWNER = SOURCE_USER' )

    loop

    BEGIN

    execute immediate 'GRANT SELECT ON SOURCE_USER.”' || x.TABLE_NAME || '” TO YOUR_USER';

    END;

    end loop;

    end;

     

    begin

    for x in ( select VIEW_NAME from DBA_VIEWS WHERE OWNER = ' SOURCE_USER ' )

    loop

    BEGIN

    execute immediate 'grant select on SOURCE_USER. ”' || x.VIEW_NAME || '” to YOUR_USER ';

    END;

    end loop;

    end;

  • Triggers: Triggers must be created directly in the configuration of SEI users in OLAP ManagerOLAP Manager with the proper security level. This is required to avoid the case where the ERP will insert rows in a table with a trigger that will not have the proper access to the tracking tables.

    To add the proper authorization level to the user:

    grant create any trigger to YOUR_USER;

    The data source is configured with the SEI schema and the SEI user. You will put SEED in the source schema and SEICube in the SEI schema.

    When you build the OLAP Cube, the tracking table and the trigger will be created in the SEI user, and no table will be created in the source user. The trigger will thus have automatically access to the tracking table.

    When a record is inserted in the source user (ex : SEED.GACCENTRYD) from a source user (ex: SEED), the data will be inserted and the trigger will be executed with the authorization of SEI user since it resides in the source user.
