5 2.1.1) On-boarding Service Redcentric will review and advise on major issues that could affect the on-boarding of the relevant managed database instance. Monitoring setup Redcentric will implement its own monitoring suite with standard thresholds and the alerts generated will form part of Redcentric s daily monitoring. Backup schedule On implementation, Redcentric will create a backup scheduled using the maintenance plan or Oracle recovery manager (RMAN), which will schedule daily backups of the database(s). The back-up data will be retained for up to 7 days dependant on the storage limits. Redcentric consultant will discuss options for the retention of data for longer periods and how best to achieve this. The maintenance of data longer than 7 days old would not be a part of this service. The backup plan will be reviewed upon request thereafter. Offsite backup services can be provided as a premium service.

7 ) Oracle Real Application Clusters In database computing, Oracle Real Application Clusters (RAC) an option for the Oracle Database software produced by Oracle Corporation and introduced in 2001 with Oracle9i provides software for clustering and high availability in Oracle Database environments. Oracle Corporation includes RAC with the Standard Edition of Oracle Database (aka baby RAC), but makes it an extra-charge option for the Enterprise Edition. In a non-rac Oracle database, a single instance accesses a single database. The database consists of a collection of data files, control files, and redo logs located on disk. The instance comprises the collection of Oracle-related memory and operating system processes that run on a computer system. In an Oracle RAC environment, 2 or more computers (each with an Oracle RDBMS instance) concurrently access a single database. This allows an application or user to connect to either computer and have access to a single coordinated set of data. Data Guard The software which Oracle Corporation markets as Oracle Data Guard forms an extension to the Oracle RDBMS. It aids in establishing and maintaining secondary "standby databases" as alternative/supplementary repositories to production "primary databases". Oracle provides both graphical and command-line tools for managing Data Guard configurations. Data Guard supports both physical standby and logical standby sites. Oracle Corporation makes Data Guard available only as a bundled feature included within its "Enterprise Edition" of the Oracle RDBMS. With appropriately set-up Data Guard operations, DBAs can facilitate failovers or switchovers to alternative hosts in the same or alternative locations. Physical standby (Redo Apply) A physical standby database replicates the exact contents of its primary database across the Oracle Net network layer. While the relative physical storage locations can differ, the data in the database will be exactly the same as the primary database. It can function either in managed-recovery mode or in read-only mode, but not in both modes at the same time unless the databases are at Oracle Database 11.1 or higher and the Active Data Guard option is licensed (See below). Logical Standby Logical standby databases convert the redo generated at the primary database into data and SQL and then re-apply those SQL transactions on the logical standby. Thus, physical structures and organization will be different from the primary database. Users can read from logical standby databases while the changes are being applied and, if the GUARD is set to STANDBY (ALTER DATABASE GUARD STANDBY), write to tables in the logical standby database that are not being maintained by SQL Apply. Unfortunately there are a number of unsupported objects (e.g. tables or sequences owned by SYS, tables that use table compression, tables that underlie a materialized view or Global temporary tables (GTTs)) and unsupported data types (i.e.: datatypes BFILE, ROWID, and UROWID, user-defined TYPEs, multimedia data types like Oracle Spatial, ORDDICOM, and Oracle Text Collections (e.g. nested tables, VARRAYs), SecureFile LOBs, OBJECT RELATIONAL XMLTypes and BINARY XML). Physical standby may be appropriate in such a case. Active Data Guard The "Oracle Active Data Guard" option, an extra licensing cost, extends Oracle Data Guard functionality in Oracle 11g configurations. It allows read-only access on the Physical standby node at the same time as applying archived transactions from the primary node. Also it features Automatic Block Repair and Fast Incremental Backup on Physical Standby. Page 6 Confidential

8 ) SQL Server Log shipping Log shipping provides high availability by creating redundancies on a per-user-database level. System databases are not covered. An initial restore of a full database backup to a warm standby system is initially required, followed by periodic transaction logs updates from the primary to the standby system. If the primary system becomes unavailable, user action is required to bring the standby database online. Automatic failover is not possible. Mirroring Database mirroring is similar to Log shipping as it also involves an initial full database restore, works on a per-user-database level and does not cover system databases. But unlike log shipping, transaction logs are applied from the primary system to the standby system as soon as they are created not at pre-set intervals. Also, Database mirroring supports several forms of failover: automatic, planned manual failover and forced manual failure. Database Mirroring s automatic failover has less than three seconds recovery time. SQL Server Clustering (Failover Cluster Instance): Unlike Log shipping and Database mirroring, Clustering provides protection at the server /Instance level. On failure, the operating system and services work together to provide automatic failover, in less than 30 seconds, to any available participating server. This failover is transparent to the client and application connecting to the SQL Server and does not require any user intervention. SQL Server failover Cluster Instances requires Windows Operating Server Clustering. AlwaysOn Introduced with the release of SQL Server 2012, AlwaysOn availability group is a robust High Availability solution that is built as a successor to Database Mirroring and offers enhanced improvements to the capabilities possible in Database Mirroring. Unlike Database Mirroring which offers protection on a per-database-basis, AlwaysOn Availability Group offers improved protection to a set of user databases called availability databases. It does this by maximizing their availability across a group of participating servers called availability replicas. Up to 5 availability replicas are supported. Each participating replica must reside on a different node of a Windows Server Failover Cluster (WSFC). On failover the set of user databases in an availability group move as a group to one of the participating replicas. Failover can be automatic in synchronous commit mode configuration or manual in an asynchronous commit mode Page 7 Confidential
