Software operating systems

The hardware and software used to implement LIMS systems must be vahdated. Computers and networks need to be examined for potential impact of component failure on LIMS data. Security concerns regarding control of access to LIMS information must be addressed. Software, operating systems, and database management systems used in the implementation of LIMS systems must be vahdated to protect against data cormption and loss. Mechanisms for fault-tolerant operation and LIMS data backup and restoration should be documented and tested. One approach to vahdation of LIMS hardware and software is to choose vendors whose products are precertified however, the ultimate responsibihty for vahdation remains with the user. Vahdating the LIMS system s operation involves a substantial amount of work, and an adequate vahdation infrastmcture is a prerequisite for the constmction of a dependable and flexible LIMS system. 

Due to the close relationship between the computer hardware and the system software, operating system installation verification may be performed during the hardware installation qualification activities. 

Before deciding on an escrow account, the legal department of the pharmaceutical company must clearly communicate to the computer system supplier the source code access requirements expected. Organizations should not require source code availability for the following software operating systems and system software, instmments and controllers, and standard software packages. 

The critical information infrastructure (CII) is a subset of the critical infrastructure, composed of the totality of interconnected computers and networks and their critical information flows [8]0, comprising therefore a vast range of components and systems, extending from hardware (satellites, routers), to software (operating systems, Internet protocols, databases), to data (DNS tables), to the processes and operations applied for running them [16]0. The CII includes typical information systems and telecommunications services, but increasingly now industrial systems (as for instance, the remote control of installations).

The determination of the sample size must be documented. An important aspect to consider in applying statistical sampling is the need to predefine the acceptability of similar systems. If the systems and their operational environment are exactly identical then a sample size of one may be sufficient. If the systems are not identical, then consideration needs to be given to what is an acceptable delta for the differences between those similar systems. Some of the deltas that one can consider may include the differences in software (operating systems, third-party tools, application program) version, patches, and fixes, as well as the deltas in hardware and equipment. 

Installation of software (operating system, standard software modules and bespoke/custom software)... 

The committee conducted a thorough review of the information management systems at the sites. This is an area that has not been thoroughly reviewed as a whole in the past by an NRC committee and includes physical facilities (servers, desktop units, storage, and distribution), software (operating systems and applications), and system development processes. The committee s major concern relates to the inconsistent way that information management is being practiced within and between sites. 

QTS software validation specifications lack details such as the hardware platforms the software should run on (model number, CPU [central processing unit], RAM [random access memory], hard drive size, free hard drive space, etc.), the software operating system, software database specifications (such as number of records accommodated, number of fields, whether those fields are character or numeric or date or alphabetical fields), the number of concurrent users allowed, the development platform used to write the application, network information, report contents and other information needed to perform testing properly. 

Certification of software. Operating systems and the software tools supporting the development process have to be certified. 

A-22. Operational experience may be regarded as statistically based evidence complementary to validation, or to the verification of system software (operating systems, communication protocols, standard functions [A-2, E3, Statistical Approaches]). 

The software employed for the eritieal elements (memory, alarming, tripping, and eommunieating with the host eomputer) uses a real-time operating system and resides in the main CPU. The administrative CPU employs multitasking software that performs important tasks sueh as modem eommunieation, trending, and arehiving. 

Because of these solutions, important technical data can be transferred from local instrumentation (control system) through data-based controllers to a control station with computers. The operator may use the many variations that the software data system provides. Technical data operation may be digital off/on messages such as the status of operation and the performance of alarms or analog measurements such as temperature, humidity, pressure, velocity, energy usage, etc. 

What they got was an entry level machine with a simple operating system and the manufacturer s own version of BASIC. There were no application packages to speak of, and there was no industry standard in software. Anyone who wrote software in those days would have nightmares about printers and disk files. 

A number of material suppliers offer information on their products on electronic devices (floppy discs, CDs, etc.) for use on personal computers. An important one, called Campus, is a database concept started by four German material manufacturers who use a uniform software. This database, initially developed jointly by BASF, Bayer, Hoechst, and Hulls, provided for other manufacturers to join. The present consortium has more than 50 materials suppliers worldwide. It is given in the form of diskettes in German, English, French, Italian, or Spanish. Each diskette contains the uniform test and evaluation program and the range of the respective material producers. It runs on IBM-compatible personal computers under the MS-DOS operating system. 

Neither database generally offers the possibility of integrating into it the greater number of values and test data that may already be established by users or processors. These organizations have data for their own internal use, and their goal has been to integrate all these types of data sources. Such in-house databases are at present available under operating system BS 2000 and in conjunction with the database software known as Adabas. 

IBM, a leader in information technologies, produces computer systems, software, networking systems, storage devices and microelectronics. It employs over 300,000 people and operates in over 100 countries. Business Innovation Services (BIS) is the consulting and systems integration arm of IBM Global Services. The organization is the... 

The software is written in the C language on an Atari ST microcomputer (1) and utilizes a GEM graphics user interface which features mouse control, windows, pulldown menus, and pop up alert and data entry boxes. The system could be ported to the IBM PC under the GEM operating system if the need were to arise. 

The Atari ST was chosen because it has a high performance graphics engine, an advanced operating system, and a large amount of easily accessible memory. These features make it an excellent value for the money. The IBM PC may be the computer of choice for business packages, but it has less technical and cost justification when used to run custom software. 

Overall control is provided by the PDP-11/44, running DEC S RSX-llM operating system. RSX-llM is a multi-user multi-task operating system, and a number of other analytical instruments are interfaced to this computer system and are running concurrently. The automated Instron software is menu-driven because our experience has shown that menu-driven software is particularly effective for applications of this type. To perform either test the user accesses a main menu from which separate menus for instrument calibration, tensile tests, and flexure tests can be reached. The tensile and flexure menus have equivalent options the choices pertaining to automated testing are as follows ... 

The package should include, insofar as possible, standard computer hardware running standard operating system and utility software. This will facilitate necessary customization and inter-system communication.
