    McObject's eXtremeDB 3.0 Adds NVRAM Support, Improved high Availability Plus Features for Performance, progress and Smaller Footprint | true questions and Pass4sure dumps

    McObject has announced the release of eXtremeDB 3.0, a major upgrade of its in-memory embedded database for knowing devices. unique features in eXtremeDB 3.0 comprise a developer's checklist of improvements, many of which build on the database's key strengths of real-time performance and ultra-small reminiscence and CPU “footprint.”

    Other additions—such as a remote access interface and support for non-volatile RAM (NVRAM, or battery-powered RAM)—contribute to developer efficiency, and bolster eXtremeDB's innovator status in providing durable and scalable data management for networked embedded systems.

    One considerable enhancement to eXtremeDB 3.0 is improved chore scheduling, which employs a speedily unique synchronization mechanism that minimizes expensive context switches, while using fewer CPU cycles to resolve resource contention. This results in improved performance and in greater scalability from low-end and even no-OS environments, to high-end Linux, Solaris, and HP-UX-based servers.

    eXtremeDB 3.0's NVRAM support presents an attractive unique recovery option for an in-memory database. NVRAM is reminiscence that is backed up by a battery so even if a device is turned off or loses its power source, the content of the reminiscence remains. eXtremeDB 3.0 enables a process to reconnect to the NVRAM-hosted database, initiate any needed cleanup, and then resume proper operation after the system reboots.

    For failsafe embedded data management, McObject offers the eXtremeDB high Availability (HA) edition. eXtremeDB HA version 3.0 adds support for “1-safe” or asynchronous replication. In 1-safe replication, a database transaction is committed on the primary node without waiting for updates to propagate to replica nodes, resulting in shorter resource holding time suitable for applications with less stringent reliability requirements (eXtremeDB already supported 2-safe or synchronous replication for systems with the strictest durability requirements). The addition of 1-safe replication provides a unique HA option for developers to tune availability and performance to the system requirements.

    “Fueled by the growth of the Internet and a convergence of functions, technologically advanced devices must increasingly manage involved data with a proven, tightly integrated database engine,” said Stephen Balacco, embedded software analyst at Venture progress Corporation (VDC). “McObject's eXtremeDB 3.0 recognizes the unique requirements for device data management in key areas such as performance, little footprint, progress ease and flexibility.”

    As befits a database provided as a springy programming library, many of eXtremeDB 3.0's unique features consist of API additions and improvements. unique functions that enhance performance and efficiency include:

    Direct structures. In previous versions, each individual field of data classes and structures were read/written individually. In eXtremeDB 3.0, an embedded structure can be declared 'direct' and interfaces will be created to read/write the entire structure. The result is less coding and therefore a smaller code footprint, and better performance.

    Classname_delete_all() allows complete objects of a class to be deleted in a sole role convene (previously it was necessary to delete objects one at a time). The result, again, is to eliminate repetitive coding, reduce footprint, and enhance performance.

    Classname_fieldname_pack() is a unique role to release reminiscence tied up in "gaps" resulting from deleted elements in vectors. reminiscence is used more efficiently: more data can be stored in the selfsame amount of space.

    eXtremeDB offers sophisticated developer tools, and version 3.0 extends this edge with several unique features:

    The role classname_fieldname_pattern_search() offers pattern-matching, similar to the SQL wildcard capability, in eXtremeDB's aboriginal API. Pattern-matching expands eXtremeDB's partial-key search (e.g. complete names starting with “Jo”) to more involved patterns that embrace wildcard characters, such as “Jo*n*, which would match “Jones,” “Johnston,” etc.

    eXtremeDB 3.0's unique Database browser utility enables a user to browse and edit a database's contents during development, for testing and verification.

    Remote Access Interface. eXtremeDB 3.0 will generate an interface enabling programs to read from and write to eXtremeDB from different machines on a network. In earlier versions, programs interacting with the database had to reside on the selfsame target system, or developers implemented their own remote interface, for case with SOAP or CORBA.

    Unicode. eXtremeDB 3.0's support for Unicode enables expend of a wider purview of character sets (such as many Asian alphabets), which simplifies the progress process and adds to marketability of eXtremeDB-based products internationally.

    Configuring SANs for high availability | true questions and Pass4sure dumps

    The Server and StorageIO Group

    How carryout they configure a SAN as host storage of combined Win2000, NT, and Novell as a failover or clustered design?

    For high availability, SAN storage can be configured to be accessed by servers with cluster failover capabilities. For case using Microsoft-based operating systems, servers can be configured for failover and SAN storage access using clustering software from Microsoft or third-party independent software vendors (ISV). For Novell Netware environments, you could expend the Novell Clustering Services software to enable server failover. There are also clustering and failover solutions for other operating system environments, including Linux, HP HP-UX, IBM AIX, and Sun Solaris.

    In addition to server failover, path failover and management of host adapters can be allotment of a server cluster configurations as well as for gauge servers to utilize redundant SAN access paths. Path management software is available from many different vendors for different platforms. While this is an oversimplified list of things to do, your SAN storage will exigency to be configured to be accessed by the different servers including making positive that any zones are setup properly, LUN masking and mapping is adequately configured, and that failover software recognizes which SAN LUNs and volumes to access along with appropriate restart and adapter path assignments.

  • These are the devices that are most likely to fail. Ensure that you offer adequate protection for your operating system disks as well as your data disks.

  • Utilizing highly available RAID disk arrays improves your chances of not sustaining an outage due to a sole disk failure.

  • If you are utilizing Fibre Channel, ensure that each node has two sever connections to your storage devices via two sever Fibre Channel switches.

  • Ensure that hardware solutions enjoy multiple power supplies from different sources.

  • Software components can offer RAID capabilities as well; LVM can offer RAID 0, 1, 0/1. VxVM can offer RAID 0, 1, 0/1, 1/0, and 5. When utilizing software RAID, ensure that mirrored disks are on sever controllers and powered from a sever power supply.

  • Networks:

  • Ideally, enjoy at least one sever heartbeat LAN.

  • Ideally, enjoy a standby LAN for complete LAN interfaces, including heartbeat LANs.

  • Utilize multiple bridges/switches between lively and standby LANs.

  • If utilizing multiple routed IP networks between servers and clients, ensure that multiple routers are used.

  • Ensure that complete members of a network can support dynamic routing.

  • Endeavor to utilize the most robust routing protocols, e.g., RIP2 or even better OSPF.

  • If utilizing FDDI, ensure that dual attached stations are attached to sever concentrators.

  • Power Supplies

  • Ensure that you enjoy at least two independent power supplies.

  • Independent power supplies should be fed from two external power generators; that includes power supply companies. select the situation where you enjoy two independent power feeds into your data hub both from XYZ Generating Company. If XYZ Generating Company goes "bust" or loses the capability to supply you with electricity, you are byfar in a pickle. If complete else fails, your second power supply should near from an onsite generator.

  • Regularly test the faculty of your second power supply to "kick in" seamlessly when your primary supply fails.

  • Data Center:

  • You exigency to reckon your data hub as an SPOF. How are you going to deal with this? This can involve a calamity Recovery blueprint including offsite tape data storage or could be as sophisticated as an advanced cluster solution such as Metrocluster or Continentalclusters incorporating asynchronous data replication over a DWDM or WAN link.

  • Ensure that management understands the implications of not including your data hub in the overall high Availability Plan.

  • Performance:

  • Should an application fail over to an lively adoptive node, you will enjoy two applications running on one node. carryout the consumers of both applications understand and accept this?

  • Have you set up any Service level Agreements with your user communities relating to individual application performance?

  • How will you manage the performance of individual applications in the event of a failover to an lively adoptive node?

  • Will you employ technologies such as Process Resource Manager (PRM) and travail Load Manager (WLM), or leave performance management to the basic UNIX scheduler?

  • User Access:

  • Do users exigency to fulfill a UNIX login to the node that is running their application?

  • Does the user's application require a UNIX user ID to fulfill its own level of client authentication?

  • How will you manage providing consistent UNIX user and group IDs across the entire cluster?

  • Do you expend NIS, NIS+, or LDAP?

  • Do you expend Trusted Systems?

  • Security:

  • Do you enjoy a security policy for individual nodes?

  • Do you enjoy a security policy for your network(s)?

  • Do you enjoy a security policy for the cluster?

  • Do you enjoy a security policy for your data center?

  • Do you enjoy a security policy for users?

  • Does everyone concerned know and understand your security policies?

  • Do you employ third-party security consultants to fulfill penetration tests?

  • Does your organization enjoy an IT Security Department? If so, carryout they fulfill regular security audits? carryout they understand the security implications of an HP high Availability Cluster?

  • That should jog your reminiscence about the SPOF and matters relating to the availability of your applications. As you can see, it's not just about "throwing" hardware at the problem; there are lots of other technological and process related challenges that you will exigency to face if you are to offer maximized uptime to your customers.

    Let's whisk on to contemplate at the mechanics of setting up a basic high Availability Cluster.
