iv InfoSphere Change Data Capture: End-User Documentation
About InfoSphere CDC and InfoSphere CDC Management Console IBM InfoSphere Change Data Capture (InfoSphere CDC) is a replication solution that captures database changes as they happen and delivers them to target databases, message queues, or an ETL solution such as InfoSphere DataStage based on table mappings configured in the InfoSphere CDC Management Console GUI application. InfoSphere CDC provides low impact capture and fast delivery of data changes for key information management initiatives including dynamic data warehousing, master data management, application consolidations or migrations, operational BI, and enabling SOA projects. InfoSphere CDC also helps reduce processing overheads and network traffic by only sending the data that has changed. Replication can be carried out continuously or periodically. When data is transferred from a source server, it can be remapped or transformed in the target environment. The following diagram illustrates the key components of InfoSphere CDC. For more information on how to install Management Console and Access Server, see Access Server and Management Console - Installation Guide. For information on how to install your source and target replication engines, see the end-user documentation for your replication engine platform. The key components of the InfoSphere CDC architecture are described below: v Access Server—Controls all of the non-command line access to the replication environment. When you log in to Management Console, you are connecting to Access Server. Access Server can be closed on the client workstation without affecting active data replication activities between source and target servers. v Admin API—Operates as an optional Java-based programming interface that you can use to script operational configurations or interactions. Copyright IBM Corp. 2011 1
v Apply agent—Acts as the agent on the target that processes changes as sent by the source. v Command line interface—Allows you to administer datastores and user accounts, as well as to perform administration scripting, independent of Management Console. v Communication Layer (TCP/IP)—Acts as the dedicated network connection between the Source and the Target. v Source and Target Datastore—Represents the data files and InfoSphere CDC instances required for data replication. Each datastore represents a database to which you want to connect and acts as a container for your tables. Tables made available for replication are contained in a datastore. v Management Console—Allows you to configure, monitor and manage replication on various servers, specify replication parameters, and initiate refresh and mirroring operations from a client workstation. Management Console also allows you to monitor replication operations, latency, event messages, and other statistics supported by the source or target datastore. The monitor in Management Console is intended for time-critical working environments that require continuous analysis of data movement. After you have set up replication, Management Console can be closed on the client workstation without affecting active data replication activities between source and target servers. v Metadata—Represents the information about the relevant tables, mappings, subscriptions, notifications, events, and other particulars of a data replication instance that you set up. v Mirror—Performs the replication of changes to the target table or accumulation of source table changes used to replicate changes to the target table at a later time. If you have implemented bidirectional replication in your environment, mirroring can occur to and from both the source and target tables. v Refresh—Performs the initial synchronization of the tables from the source database to the target. This is read by the Refresh reader. v Replication Engine—Serves to send and receive data. The process that sends replicated data is the Source Capture Engine and the process that receives replicated data is the Target Engine. An InfoSphere CDC instance can operate as a source capture engine and a target engine simultaneously. v Single Scrape—Acts as a source-only log reader and a log parser component. It checks and analyzes the source database logs for all of the subscriptions on the selected datastore. v Source transformation engine—Processes row filtering, critical columns, column filtering, encoding conversions, and other data to propagate to the target datastore engine. v Source database logs—Maintained by the source database for its own recovery purposes. The InfoSphere CDC log reader inspects these in the mirroring process, but filters out the tables that are not in scope for replication. v Target transformation engine—Processes data and value translations, encoding conversions, user exits, conflict detections, and other data on the target datastore engine. There are two types of target-only destinations for replication that are not databases: v JMS Messages—Acts as a JMS message destination (queue or topic) for row-level operations that are created as XML documents. v InfoSphere DataStage—Processes changes delivered from InfoSphere CDC that can be used by InfoSphere DataStage jobs. 2 InfoSphere Change Data Capture: End-User Documentation
System requirements Before you install InfoSphere CDC, ensure that the system you choose meets the necessary operating system, hardware, software, communications, disk, and memory requirements. In this section, you will learn: “Supported operating systems and processors” “Supported Netezza JDBC drivers” “Supported databases” “Disk space requirements” on page 4 “RAM requirements” on page 4 “Port requirements” on page 4 Supported operating systems and processors Operating system and processor Linux Red Hat version 5.3 and later—x86/x64 processors Note: InfoSphere CDC for Netezza databases only supports 64 bit operating systems. Supported Netezza JDBC drivers Netezza JDBC driver Netezza JDBC driver, version 6.0.3 or above. Supported databases Database Netezza database version 6.0.2 The JDBC driver must be compatible with all databases you want to replicate data to or from. Please consult your database's documentation for information regarding the features supported by the drivers. Copyright IBM Corp. 2011 3
Disk space requirements Disk space InfoSphere CDC target system: v 5 GB—For installation files, data queues, and log files. v Global disk quota—Disk space is required on your target system for this quota which is used to store LOB data received from your InfoSphere CDC source system. The amount of disk space required is determined by your replication environment and the amount of LOB data you are replicating. To improve performance, InfoSphere CDC will only persist LOB data to disk if RAM is not available on your target system. Use the mirror global disk quota gb system parameter to configure the amount of disk space used by this quota. RAM requirements RAM Each instance of InfoSphere CDC requires memory for the Java Virtual Machine (JVM). The following default values for memory are assigned: v 8192 MB of RAM—Default value for each 64-bit instance of InfoSphere CDC. Use the InfoSphere CDC configuration tool to configure the memory for each instance of InfoSphere CDC. Although InfoSphere CDC memory requirements will fluctuate, you must work with your system administrator to ensure the allocated memory for each instance of the product is available at all times. This may involve deployment planning since other applications with memory requirements may be installed on the same server with InfoSphere CDC. Using values other than the defaults or allocating more RAM than is physically available on your server should only be undertaken after considering the impacts on product performance. Related concepts “Configuring InfoSphere CDC (Linux)” on page 13 Port requirements InfoSphere CDC requires that you allocate a port for communication with client workstations running Management Console and other servers. The port must be accessible through a firewall, although you do not require access to the Internet. Protocol Default port Purpose TCP 11301 Accepts connections from: v Management Console v Other installations of InfoSphere CDC as a source of replication v Command line utilities For more information on how to install Management Console, see Management Console and Access Server Installation Guide. 4 InfoSphere Change Data Capture: End-User Documentation

Before you install This section contains information on the tasks that you must complete before installing InfoSphere CDC. This section assumes that you have met all of the hardware, software, database, and port requirements. You must complete all of the tasks below before installing InfoSphere CDC. In this section, you will learn: “Required database, user accounts, and privileges” “Assessing disk space and memory requirements” “Netezza specific considerations for InfoSphere CDC” on page 8 “Preparing your environment for an installation of InfoSphere CDC” on page 8 “Calculating database connections required by InfoSphere CDC” on page 9 Required database, user accounts, and privileges Configuring a connection to the Netezza database When you configure InfoSphere CDC, you are prompted for the hostname of the Netezza database you want InfoSphere CDC to connect to and replicate data. Before installing InfoSphere CDC, ensure that this database exists and that you have created and set up a database user that has access to it. Setting up a Linux user account When you are installing InfoSphere CDC on a Linux machine, you must set up a new, or decide on an existing Linux account that you will use to install, configure, or upgrade InfoSphere CDC. You can install InfoSphere CDC in the directory of your choice, however, it must be owned by the Linux account. Configuring an Netezza database When you configure InfoSphere CDC, you are prompted for the name of the Netezza database from which you want InfoSphere CDC to replicate data. Before installing InfoSphere CDC, ensure that this Netezza database exists and that you have created and set up a database user that has access to it. Assessing disk space and memory requirements InfoSphere CDC requires disk space and memory when it processes change data from your source database. In order to process change data efficiently and replicate these changes to your target system, it is very important that InfoSphere CDC has adequate disk space and memory for each of the components described in this section. Memory requirements for the JVM (Java Virtual Machine) As a Java-based product, InfoSphere CDC requires you to allocate the maximum amount of memory (RAM) to be used by the Java Virtual Machine (JVM). This prevents InfoSphere CDC from using all of the available memory on the system where it is installed. Copyright IBM Corp. 2011 7
The Maximum Memory Allowed value is set on a per-instance basis for each instance you create for your target database. In most cases the default values are appropriate for 64-bit instances. However, if your database is processing an extremely heavy workload, you may have to adjust the default values. The RAM allocated must be physically available on your system. Disk space requirements for the global disk quota Disk space is required on your target system for this quota which is used to store in-scope change data that has not been committed in your database. The amount of disk space required is determined by your replication environment and the workload of your source database. You can configure the amount disk space that is allocated to this quota with the mirror global disk quota gb system parameter. The default setting of this system parameter is such that InfoSphere CDC will only stop replicating after this disk quota exhausts all available disk space on your system. If you would prefer InfoSphere CDC to stop replicating after it uses a specific amount of disk space, you can specify the value with this system parameter in Management Console. Netezza specific considerations for InfoSphere CDC There are several Netezza specific considerations you should review when working with InfoSphere CDC. v In order to maintain Netezza's operational efficiency, InfoSphere CDC for Netezza databases replicates rows in periodic bulk load operations. As an administrator of InfoSphere CDC, you can expect a certain level of latency (in minutes) during replication because these operations are staged in memory before they are applied to the database. Latency may be higher when compared to InfoSphere CDC performance on other supported databases, however the throughput of rows per hour may be similar or greater. If you want to control the level of latency in your environment, you can modify the acceptable latency in minutes system parameter in Management Console. v InfoSphere CDC for Netezza databases attempts to apply data such that SQL query performance against the target database is minimally affected. Replication of large volumes of changed data may affect query performance because of bulk load operations being performed on the database. Query performance may also be affected by the level of acceptable latency you specify with the acceptable latency in minutes system parameter. v While the Netezza appliance permits and maintains primary key, default, foreign key, unique, and references, the appliance does not support constraint checks and referential integrity. Therefore, InfoSphere CDC will not be able to detect situations where the data has been changed either manually or by an application. As an administrator ofInfoSphere CDC for Netezza databases, you must ensure that there are no duplicate rows in the table and ensure referential integrity in the data being replicated. Preparing your environment for an installation of InfoSphere CDC You need to allocate a Linux Red Hat version 5.3 or later machine on which you can install InfoSphere CDC. This Linux machine should be close to the Netezza appliance in order for InfoSphere CDC to obtain a strong network connection. Before you install, consider the following: 8 InfoSphere Change Data Capture: End-User Documentation
v You can only install one instance of InfoSphere CDC for Netezza databases on a single Netezza database. v InfoSphere CDC must not be installed on the Netezza appliance. v InfoSphere CDC for Netezza databases only supports 64 bit Linux operating systems. The following diagram illustrates a typical topology for InfoSphere CDC for Netezza databases product. Calculating database connections required by InfoSphere CDC As an administrator, you may find it necessary to calculate how many database connections are needed before installing InfoSphere CDC on either a source or a target database. Calculating the upper bound (both permanent and temporary) database connections will help you plan your environment so that it can accommodate InfoSphere CDC. If you are installing InfoSphere CDC for Netezza databases, then you only need to calculate database connections for the target database as this product only replicates to target-only destinations. This topic includes the formulae and examples to help you calculate the number of connections required by InfoSphere CDC versions 6.5.x or 6.3.x. Only calculations for 6.5.x are relevant for the InfoSphere CDC for Netezza databases product. Calculating connections required by InfoSphere CDC version 6.5.x or 6.3.x on a target database For InfoSphere CDC version 6.5.x or 6.3.x: (4 G)*N 3*T Where: v T number of InfoSphere CDC subscriptions (target datastore in Management Console is version 6.5.x or 6.3.x). v G number of Management Console GUI applications that are connected to your instances of InfoSphere CDC. v N number of InfoSphere CDC 6.5.x instances. Example: How to calculate required connections for a target database You want to setup InfoSphere CDC in the target environment as follows: v 3 subscriptions. v 2 InfoSphere CDC 6.5.x instances. v 1 installed Management Console GUI application. Before you install 9
The number of connections required on the target database will be: (4 1)*2 3*3 19 You should plan for a maximum of 19 database connections before installing InfoSphere CDC on the target database. 10 InfoSphere Change Data Capture: End-User Documentation
