The high parse rates are due to the following factors: An undersized shared pool Failure to use bind variables Using dissimilar SQL statements and failing to reuse statements Users frequently logging off and logging back into the application Failure to keep cursors open after each execution Using a shared pool size that s too large The cache buffers LRU chain latch free wait is caused by high buffer cache throughput, either due to full table scans or the use of unselective indexes, which lead to large index range scans Unselective indexes can also lead to yet another type of latch free wait: the cache buffer chain latch free wait These wait events are often due to the presence of hot blocks, so you need to investigate why that might be happening. java read barcode from image open source BAR CODE READER Java App - Download for free on PHONEKY

If you see a high value for row cache object latch waits, it indicates contention for the dictionary cache, and you need to increase the shared pool memory allocation In most instances, latch waits tend to show up as a wait event, and DBAs sometimes are alarmed by their very presence in the wait event list As with the other Oracle wait events, ask yourself this question: Are these latch waits a significant proportion of my total wait time If the answer is no, don t worry about it your goal isn t to try and eliminate all waits in the instance, because you can t do it..

The log buffer space wait event indicates that a process waited for space in the log buffer. Either the log buffer is too small or the redo is being written faster than the log writer process can write it to the redo log buffer. If the redo log buffer is already large, then investigate the I/O to the disk that houses the redo log files. There s probably some contention for the disk, and you need to work on reducing the I/O contention. This type of wait usually shows up when the log buffer is too small, in which case you increase the log buffer size. A large log buffer tends to reduce the redo log I/O in general. Note that Oracle s default value for this parameter is several megabytes in size. If you have a large number of huge transactions, you might want to bump up the value of the LOG_BUFFER initialization parameter from its default value, although too high a value means that too much data may have to be written to the redo log files at one time. The log file switch wait event can occur when a session is forced to wait for a log file switch because the log file hasn t yet been archived. It can also occur because the log file switch is awaiting the completion of a checkpoint. If the problem isn t due to the archive destination getting full, it means that the archive process isn t able to keep up with the rate at which the redo logs are being archived. In this case, you need to increase the number of archiver (ARCn) processes to keep up with the archiving work. The default report need to be consistent with respect to a single point in time In other systems, you would use REPEATABLE READ and suffer the associated affects of the shared read lock In Oracle, you will use the READ ONLY transaction In this mode, the output you produce in a report that uses 50 SELECT statements to gather the data will be consistent with respect to a single point in time the time the transaction began You will be able to do this without locking a single piece of data anywhere This aim is achieved by using the same multi-versioning as used for individual statements The data is reconstructed as needed from the rollback segments and presented to you as it existed when the report began READ ONLY transactions are not trouble-free, however. java read barcode from image open source QuaggaJS, an advanced barcode - reader written in JavaScript
