Setting up an Oracle database
Before you begin
Make sure that you have downloaded the ORACLE_ARSystem-SR_213006HF-DBDUMP.zip file from BMC Electronic Product Distribution (EPD).
To prepare your Oracle database
As a database administrator, install at least one instance of the Oracle database.
You can install it on a remote server that is accessible to sever where you want to install AR System.- Enable TCP/IP for the database.
- Confirm connection to your Oracle database.
Contact your database administrator for more information. Set the AR System data file size to at least 2 GB.
Make sure that the database parameters listed in the following table are specified:
Parameter Name
Suggested value
cursor_space_for_time
False
db_block_checking
False
db_file_multiblock_read_count
0 (or do not set)
LOG_BUFFER
10485760
OPEN_CURSORS
500
optimizer_dynamic_sampling
2
session_cached_cursors
100
statistics_level
Typical
timed_statistics
True
UNDO_RETENTION
14400
workarea_size_policy
auto
REDO log files
Three (at least 1 GB each)
NLS_LENGTH_SEMANTICS
BYTE
NLS_CHARACTERSET
AL32UTF8
To prevent AR System from reaching the size limit of the database, set your tablespaces with the AUTOEXTEND parameter to ON, by executing the following SQL statement as the system user:
ALTER DATABASE DATAFILE '<OracleHome>/DATABASE/ARSYS' AUTOEXTEND ON NEXT 100M MAXSIZE UNLIMITED;Set the tablespace and temporary tablespace to at least the following minimum settings:
Parameter
Suggested value
arsys
2000 MB
artmpf
500 MB
The tablespace names might be different for your environment.
- To avoid timeout errors during installation, set the System Global Area (SGA) minimum size to at least 1 GB (small database), 3 GB (medium database), or 6 GB (large database). For Oracle 11g, set the maximum SGA size and enable the database to automatically manage the internal memory structures of the SGA. For example, to change the SGA size to 1 GB, use the alter system set sga_target=1G scope=both command.
Verify or set the following environment variables:
Environment variable
Description
NLS_LANG (Windows)
Set NLS_LANG as a system environment variable value as per your database character set .
For information about NLS_LANG and its usage, see the following notes from Oracle: 144808.1, 227330.1, 260192.1.
LANG (UNIX)
Specifies globalization settings.
ORACLE_SID
Set the length of this variable to 8c.
- Ensure that the Oracle listener is running and is configured correctly for the database.
- Set the value of the Oracle CLOB option to inrow.
(Oracle 12c Release 2 only) Add the following parameters and values to sqlnet.ora:
Parameter and value
Purpose
SQLNET.AUTHENTICATION_SERVICES = (NTS)
Required by Oracle 12.2 to enable the AR System server to run on Windows with the database on Windows.
SQLNET.ALLOWED_LOGON_VERSION_SERVER = 10
Required by Oracle 12.2 to connect the database to AR Systems clients, which contain version 10 of the Oracle client library.
To configure your Oracle database
- Unzip the ORACLE_ARSystem-SR_213006HF-DBDUMP.zip file that you downloaded from EPD.
The following database dump files are displayed:- ORACLE_ARSystem-213006HF-202211181051.dmp
- ORACLE_SmartReporting-210503HF-202208181627.dmp
Download and update the following files:
File
Description
This file creates users, database schemas, and table spaces required for setting up database configurations for Action Request System and BMC Helix ITSM: Smart Reporting.
Update this file with the appropriate parameter values.
- Log in to your database server by using the Oracle user credentials and copy the files to the required path such as /data1/DB_DUMP/ or C:\data1\DB_DUMP.
- Change your directory to the directory path where you copy the Data_Population_Script_for_Innovation_Suite and Innovation_Suite_schema_tablespace_creation.sql files.
Execute the Innovation_Suite_schema_tablespace_creation.sql file by using the following command:
sqlplus system/<Password> @Innovation_Suite_schema_tablespace_creation.sqlExecute the Data_Population_Script_for_Innovation_Suite file.
- On Windows, perform the following steps:
- In the database server, rename the Data_Population_Script_for_Innovation_Suite file to Data_Population_Script_for_Innovation_Suite.bat
Start command prompt, navigate to the directory that contains the Data_Population_Script_for_Innovation_Suite.bat file and execute the file by using the following command:
cmd Data_Population_Script_for_Innovation_Suite.bat
On Linux, in the database server, execute the file as an Oracle user by using the following command:
sh Data_Population_Script_for_Innovation_Suite
Make sure that the file is executed successfully.
- On Windows, perform the following steps:
Considerations for an Oracle 12c or 18c database
If you have an Oracle 12c or 18c database, consider the following:
- Consult your Oracle DB administrator to understand the architectural changes in Oracle 12c and 18c.
- The following options are available when you choose to use the Oracle 12c or 18c database:
- If you want to use a non multi-tenant database, you must create a non-Container Database (CDB) database.
- If you want to use a multi-tenant database, you must create a CDB with Pluggable Database (PDB) inside it.
- If you are using non-CDB, no specific settings are required.
- If you are using the CDB with PDB inside it, perform the following steps before installing BMC Helix Service Management:
- Create the PDB.
For example, you could create a database called REMPDB. Register the PDB as service to the listener.
- Create the PDB.
Cursor sharing
Set the value of cursor_sharing to FORCE.
Configuring Oracle Data Guard
Beginning with the AR System 9.1.02, BMC supports Oracle Data Guard. Oracle Data Guard is a technology that helps in recovering from DB failures across the geographical sites. Clients can failover to the next available database in the Oracle Real Applications Cluster (RAC) setup. For more information, see Oracle Data Guard.
To configure AR System to support Oracle Data Guard
The following image shows the AR system server with Oracle Data Guard.
Perform the steps to configure AR System to support Oracle Data Guard:
- On the AR System Server, configure a service that has the same name for the primary and standby database. For example, ORADG.BMC.COM.
In the AR System Configuration Generic UI form, set the Oracle-JDBC-URL parameter to the specified syntax:
Oracle-JDBC-URL: jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=OFF)(FAILOVER=ON)(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=primarydb_host)(PORT=primarydb_port))(ADDRESS=(PROTOCOL=TCP)(HOST=standbydb_host)(PORT=standbydb_port)))(CONNECT_DATA=(SERVICE_NAME=ORADG.BMC.COM)(SERVER=DEDICATED)))- Save the file.
- Restart the BMC Helix Innovation Suite platform pod.
When the primary database is down and the standby database does not take over as the primary database, the following error occurs:
After your BMC Helix Service Management is installed and you have configured it to support Oracle Data Guard, you can log in as AR Admin to verify the configuration.
