About this Document

This document can be used to set up WebSphere Process Server 6.1.0.1 Clustered environment using theDeployment Environment feature of the WebSphere Process Server Deployment Manager AdministrativeConsole. The database used for this exercise is Oracle 10g.

The objective of this document is to separate the WebSphere Process Server installation and configuration partfrom the database interaction part (where scripts are run to create the required tables and table spaces). This willallow the WebSphere Process Server install user to finish Installation and Configuration and hand off the scriptsto the DBA who will set up the database tables for the WebSphere Process Server installation.

Also note that this document does not discuss Administrative and Application Security, nor does it discussDatabase or Performance tuning. The main objective of this document is to be a lab exercise in setting up aClustered topology using the WebSphere Process Server administrative console. Refer to the WebSphereProcess Server Information Center for additional information about Security and Database performanceconsiderations:http://publib.boulder.ibm.com/infocenter/dmndhelp/v6r1mx/index.jsp?topic=/com.ibm.websphere.wps.610.doc/wel

Configuring Oracle Java™ Virtual Machine (JVM)The Oracle Database needs to have the Oracle JVM (or JServer in 9i terms) enabled. To enable this, you canuse the Oracle Database Configuration Assistant or specific SQL scripts. See the Oracle documentation fordetails.

You can check whether the Oracle JVM/JServer component is installed by invoking the following query fromSQL*Plus, as SYS:

1. (Oracle 9i) describe dbms_java2. (Oracle 10g) select version, status from dba_registry where comp_id='JAVAVM';

In addition, the correct privilege to run Java needs to be granted to each of our users (you will receive XA errors ifyou do not do this). For each user, the Oracle DBA needs to run the following command:

grant javauserpriv to <user>;

This is done later in this article for each database user.

Configuring XA for Oracle

XA is a two-phase commit protocol defined by the X/Open DTP group. The database used by WebSphereProcess Server needs to be XA enabled. To do this, two tasks need to be carried out by your DBA:

The <ORACLE_HOME>/javavm/install/initxa.sql script needs to be run on the WPSDB database. This scriptconfigures the database for XA. More information on this requirement is available from Configuring and using XAdistributed transactions in WebSphere Studio, see the Resources section.

1. The following queries need to be executed:

grant select on pending_trans$ to public;grant select on dba_2pc_pending to public;grant select on dba_pending_transactions to public;grant select on V$XATRANS$ TO PUBLIC;

Note: If the last query fails, it means that the V$XATRANS$ view does not exist. You need to prepare the Oracledatabase for XA transactions recovery by executing the xaview.sql script located under<ORACLE_HOME>/RDBMS/ADMIN.

Additionally, for each user, you will need to grant access to dbms_system (this is done later for each user).

Database Users/Privileges ConsiderationsFor the purposes of this article, we configured everything in a single Oracle database. This is an initialconfiguration, and would probably be modified after reviewing the performance of the databases. Since we are

using the Deployment Environment feature from the administrative console, and will be delaying the execution ofdatabase scripts, we do not need any database access during the WebSphere Process Server installation. Youmay have your DBA create the required users/schemas according to the following table and privileges (with theexception of Common Event Infrastructure (CEI).

Table 1 lists the database schemas that are required for WebSphere Process Server, along with the names usedfor the user IDs (schemas) in the configuration presented in this article.

Table Database TablesSchema/Userid usedin this article

Business Process Container configuration

BPCOBS First 3 letters of instanceSID + BC00 Business Process Observer

Have your DBA create the above users according to the privileges below. Note that the ‘CREATE/GRANT’commands below assume it is the DBA that is running these commands.

Common database User (WPSDB)The Process Server configuration database user, WPCDB, has no special requirements other than it must exist.To create it, your DBA needs to run a command equivalent to the following:

create user WPSDB identified by passw0rd;grant connect, resource, unlimited tablespace to WPSDB;

grant execute on dbms_system to WPSDB;grant javauserpriv to WPSDB;

The above commands use the system’s default tablespace; your DBA may wish to specify a different tablespaceand this is fine.

Business Process Container User (BPCDB)To create the Business Process Container database user, the DBA needs to run a command similar to:

create user BPCDB identified by passw0rd;grant connect, resource, create tablespace, drop tablespace, create view, unlimited tablespace to BPCDB;grant execute on dbms_system to BPCDB;

grant javauserpriv to BPCDB;



4

Business Process Container Observer User (BPCOBS)create user BPCOBS identified by passw0rd;grant connect, resource, create tablespace, drop tablespace, create view, unlimited tablespace to BPCOBS;grant execute on dbms_system to BPCOBS;grant javauserpriv to BPCOBS;

Common Event Infrastructure (CEI) UserConfiguring CEI generates a whole set of scripts that include actions to create tablespaces, roles and a CEI userbased on the database information provided during configuration. These scripts may be handed off to the DBA forexecution as some of the scripts need DBA-like privileges for creating the user and linking the roles andtablespaces to this user.

ESB Message Logger User (ESBLOG)The ESBLOG.MSGLOG table is used by the Message Logger ESB primitive to log messages.

create user ESBLOG identified by passw0rd;grant connect, resource, unlimited tablespace to ESBLOG;grant execute on dbms_system to ESBLOG;grant javauserpriv to ESBLOG;

Messaging engines DatastoresThe same table names (SIB000, SIB001, etc.) are used by each messaging engine; therefore, you need to use a

specific schema (user) for each messaging engine.

create user SCASYSME identified by passw0rd;grant connect, resource, unlimited tablespace to SCASYSME;grant execute on dbms_system to SCASYSME;grant javauserpriv to SCASYSME;

create user SCAAPPME identified by passw0rd;grant connect, resource, unlimited tablespace to SCAAPPME;grant execute on dbms_system to SCAAPPME;grant javauserpriv to SCAAPPME;

create user CEIME identified by passw0rd;

grant connect, resource, unlimited tablespace to CEIME;grant execute on dbms_system to CEIME;grant javauserpriv to CEIME;

create user BPCME identified by passw0rd;grant connect, resource, unlimited tablespace to BPCME;grant execute on dbms_system to BPCME;grant javauserpriv to BPCME;
