Although a large percentage of MVS and OS/390 installations still store vast volumes of business-critical data in VSAM files, the MVS operating system offers only limited functionality to support recovery of VSAM data.
The RECOVERY UTILITY for VSAM product from BMC Software is a versatile recovery management tool for both batch and online environments.
RECOVERY UTILITY provides all of the backup services, recovery management, journal-record and logrecord management and reporting capabilities necessary for successful application data recovery for MVS and OS/390 users.
In addition to its VSAM recovery management products, BMC Software delivers other solutions for improving the availability and performance of business-critical VSAM applications.
fec
To address the specific needs, such as data loss and transmission delay, of these applications, FEC (Forward Error Correction) techniques based on error correcting codes are widely used.
The choice of codes and their parameters are crucial in determining the efficiency of FEC, in terms of loss recovery capability, bandwidth use and computation complexity.
It is, however, much more difficult to get closed form representation of the unrecoverable ratio of the PARITY code or the XEOD for a bursty loss model, if possible at all.
For each simulation, we let the first 10,000 states of the Gilbert model pass to ensure our experiments always start from a steady state.

BitBlitz Communications, Fremont, CA Parallel optical communication and back-plane applications require multiple high-speed electronic transceivers with low-jit-ter clock-and-data recovery (CDR) units.
Analog CDR uses one VCO per CDR and produces a low-jitter recovered clock.
Digital phase interpolation uses only one oscillator for multiple CDRs, which lowers its per-channel power consumption, but its baseline jitter is high due to the finite phase steps [1,2].
This CMOS analog phase-rotator CDR combines the benefits of the above two architectures, i.e., multiple-channel operation, low jitter, and low power consumption.
The quad transceiver also includes receiver equalization, and built-in self-test (BIST) functions.
The transceiver provides 12.5Gb/s duplex raw data rate, or 3.125Gb/s per channel.

· WHAT WOULD BE THE COST OF RECOVERY - BOTH TANGIBLE AND INTANGIBLE COSTS?
· HOW WOULD THE ORGANIZATION HANDLE THE BACKLOG?
IF you do not have an answer for any of these questions, and IF the answers to these issues are not documented you probably need a recover plan.
· The BCP is regularly tested, it is correct, complete and up to date.
The Plan must direct the operations of a company during a crisis and have a favorable impact upon how the company operates after the crisis.

The frequency acquisition control loop initially acquires the clock frequency of the input data.
The phase-lock loop then acquires the phase of the input data, and ensures that the phase of the output signals track changes in the phase of the input data.
The loop damping of the circuit is dependent on the value of a user selected capacitor; this defines jitter peaking performance and impacts acquisition time.
This is the range of input data rates over which the PLL will remain in lock.
Termination resistors should be used for DATAIN, CLKOUT, DATAOUT, and FRAC signals.
A ceramic capacitor may be used for the loop damping capacitor.
The damping ratio of the phase-locked loop is user programmable with a single external capacitor.

Fortunately, there are specialized hardware and software companies that manufacture products for the centralized backup and recovery of business-critical data.
Hardware manufacturers offer automated tape libraries that can manage millions of megabytes of backedup information and eliminate the need for operators charged with mounting tape cartridges.
It is often due to organizations' ever-shrinking backup windows, inadequate network infrastructure, and a lack of system administration.
The company delivers customized solutions that help meet customers' specific business and financial objectives.
StorNet Solutions analyzes storage requirements, architects solutions; implements secure automated systems, and provides training, support, and management services.

Abstract--- A non-data aided carrier recovery technique using modulation format identification is proposed.
The performance of the proposed technique is studied and analytical expressions derived for the mean acquisiton time to detect lock in the cases of -PSK,, and -QAM modulation, with respect to frequency offset and signal-to-noise ratio.
This is a very desirable feature in a software radio receiver.
Simulation results and theoretical expressions on the mean acquisition time are shown in Figs. 2 to 5.
For both phase and carrier offset equal to zero, the lock probabilities of the modulation schemes considered in this paper are shown in Fig. 6.

Stac is an American software development company specializing in system back-up/recovery products.
In 1999, Stac decided to outsource the further development and maintenance of Replica Tape and announced a public tender, which STAR Software subsequently won.
Rose is the latest (fifth) and the largest project in the context of this long term collaboration.
Rose is the Tivoli Data Protection OEM release built on Stac's Replica Disaster Recovery Component architecture (Python) code base.
Rose provides backup protection and disaster recovery for PC-based Server systems, which are otherwise not protected by ADSM while integrating with the ADSM scheduling capabilities and centralized error logging.
This is the third version of the Tivoli- branded product and it adds Windows 2000 support to the product line.
