Copy. or NIO Interesting issues arise in such an architecture, since the time cost of communication between the client and the server is high compared to that of a local memory reference (milliseconds, versus less than 100 nanoseconds): Page shipping versus item shipping The unit of communication for data can be of coarse granularity, such as a page, or ne granularity, such as a tuple (or an object, in the context of object-oriented database systems) We use the term item to refer to both tuples and objects If the unit of communication is a single item, the overhead of message passing is high compared to the amount of data transmitted Instead, when an item is requested, it makes sense also to send back other items that are likely to be used in the near future Fetching items even before they are requested is called prefetching Page shipping can be considered a form of prefetching if multiple items reside on a page, since all the items in the page are shipped when a process desires to access a single item in the page Locking Locks are usually granted by the server for the data items that it ships to the client machines A disadvantage of page shipping is that client machines may be granted locks of too coarse a granularity a lock on a page implicitly locks all items contained in the page Even if the client is not accessing some items in the page, it has implicitly acquired locks on all prefetched items Other client machines that require locks on those items may be blocked unnecessarily Techniques for lock de-escalation, have been proposed where the server can request its clients to transfer back locks on prefetched items If the client machine does not need a prefetched item, it can transfer locks on the item back to the server, and the locks can then be allocated to other clients Data caching Data that are shipped to a client on behalf of a transaction can be cached at the client, even after the transaction completes, if suf cient storage space is available Successive transactions at the same client may be able to make use of the cached data However, cache coherency is an issue: Even if a transaction nds cached data, it must make sure that those data are up to date, since they may have been updated by a different client after they were cached Thus, a message must still be exchanged with the server to check validity of the data, and to acquire a lock on the data Lock caching If the use of data is mostly partitioned among the clients, with clients rarely requesting data that are also requested by other clients, locks can also be cached at the client machine Suppose that a client nds a data item in the cache, and that it also nds the lock required for an access to the data item in the cache Then, the access can proceed without any communication with the server However, the server must keep track of cached locks; if a client requests a lock from the server, the server must call back all con icting locks on the data item from any other client machines that have cached the locks The task becomes more complicated when machine failures are taken into account This technique differs from lock de-escalation in that lock caching takes place across transactions; otherwise, the two techniques are similar. write byte array to pdf in java: Java - Convert byte[] to File - Programmer Gate java write pdf bytes converting byte array of a pdf into a string (Java in General ...

Parallel systems improve processing and I/O speeds by using multiple CPUs and disks in parallel Parallel machines are becoming increasingly common, making the study of parallel database systems correspondingly more important The driving force behind parallel database systems is the demands of applications that have to query extremely large databases (of the order of terabytes that is, 1012 bytes) or that have to process an extremely large number of transactions per second (of the order of thousands of transactions per second) Centralized and client server database systems are not powerful enough to handle such applications In parallel processing, many operations are performed simultaneously, as opposed to serial processing, in which the computational steps are performed sequentially A coarse-grain parallel machine consists of a small number of powerful processors; a massively parallel or ne-grain parallel machine uses thousands of smaller processors Most high-end machines today offer some degree of coarse-grain parallelism: Two or four processor machines are common Massively parallel computers can be distinguished from the coarse-grain parallel machines by the much larger degree of parallelism that they support Parallel computers with hundreds of CPUs and disks are available commercially There are two main measures of performance of a database system: (1) throughput, the number of tasks that can be completed in a given time interval, and (2) response time, the amount of time it takes to complete a single task from the time it is submitted A system that processes a large number of small transactions can improve throughput by processing many transactions in parallel A system that processes large transactions can improve response time as well as throughput by performing subtasks of each transaction in parallel how to write pdf file in java using itext Java: Need to create PDF from byte-Array - Stack Overflow

The RMON MIB is a specific collection of objects used for remote monitoring networks The RMON MIB is defined by RFC 1757 and RFC 1513 Figure 2911 shows how the RMON MIB is broken down into ten objects or groups The first nine define monitoring of Ethernet networks; the tenth defines extensions for Token-Ring There currently are no standards for monitoring FDDI, 100Base-X, or WAN networks RMON vendors have added their own proprietary extensions for these additional media types RMON is limited because it gives visibility only up to the Data Link layer (layer 2) in the OSI stack A brief description of the ten RMON MIB groups will provide some insight into the variables that can be collected by monitoring traffic on a network Statistics group This group contains segment statistics, collected in 32-bit counters, that include items such as packets, dropped packets, broadcasts, and multicasts These are just counters and not studies History group This group contains segment history statistics for various counters, such as broadcasts, errors, multicasts, packets, and octets These numbers are for certain time periods RMON defines two default time periods, 5 seconds and 1800 seconds 1 In the Advanced Access Control console, select the node for the scan package that you just imported 2 Choose the Create scan task java write pdf file to response Convert JPG to PDF iText Java Example Tutorial | ThinkTibits!
