GS1 - 13 Generator In C#
Using Barcode drawer for VS .NET Control to generate, create EAN-13 image in Visual Studio .NET applications.
The shared_buffers value determines the amount of overall memory PostgreSQL will consume Each shared buffer is 8124 bytes Unfortunately, there are no hard rules for setting this value One rule of thumb is that it should be at least double the number you define in the max_connections feature value Obviously, the larger the value the more memory PostgreSQL will use, and the faster the PostgreSQL system will operate

Most PostgreSQL administrators recommend using a value of at least 2000, and working up or down from there, depending on the performance of your particular system For a standard Windows workstation installation, the default value of 1000 should be fine

Make Bar Code In None
Using Barcode creator for Font Control to generate, create bar code image in Font applications.
This feature determines the maximum number 8124 byte temporary memory buffers used by each database session As individual sessions access tables, temporary memory buffers are created to store information You can limit the amount of memory each session is allowed to consume using this value Again, this is a performance feature that can be experimented with in your specific PostgreSQL environment

max_prepared_transactions = 5
Create Bar Code In Java
Using Barcode maker for Java Control to generate, create barcode image in Java applications.
Creating Barcode In Java
Using Barcode generation for Android Control to generate, create bar code image in Android applications.
The max_prepared_transactions feature value determines the number of simultaneous transactions that are in the PREPARE TRANSACTION process before the two-phase transaction commit process is run (transactions are discussed in 7) Processing a transaction uses memory resources, so allowing parallel transaction processing, while helpful in increasing database performance, can be a drain on system memory If your applications do not use this feature, you can set this value to zero If you are in a multiuser environment, this value should be at least as large as the max_connections feature value, so each client has the ability to have transactions processed simultaneously
work_mem = 1024
This feature limits the amount of memory used by internal sort and hashing functions in the entire PostgreSQL system This value is in kilobytes, so the default value of 1024 kilobytes is 1MB of memory space If a sort or hash function exceeds this limit, data is swapped out to temporary files to complete the process This is extremely costly to database performance, and is a crucial element in performance tuning (see 10)
maintenance_work_mem = 16384
Sets the amount of memory (in kilobytes) allowed for internal PostgreSQL database maintenance operations These functions include creating table indexes, removing deleted records, and altering existing tables This value is in kilobytes, so the default value is 16MB
max_stack_depth = 2048
This feature sets the size of the PostgreSQL server s execution stack level This limits the number of processes that can wait for execution The value is in kilobytes, so the default value is 2MB
max_fsm_pages = 20000 max_fsm_relations = 1000
PostgreSQL 8 for Windows
The max_fsm_relations value should be set to the maximum number of tables and indexes you plan on having in your database The max_fsm_pages value defines the number of disk pages for which free space will be tracked This value should be at least 16 times the value in the max_fsm_relations value
max_files_per_process = 1000
The max_files_per_process feature limits the number of open files a single PostgreSQL process can have
preload_libraries = ''
This feature specifies a list of libraries that are preloaded into the PostgreSQL server at startup The default is not to load any libraries The next group of features in the Resource Usage section deals with database vacuuming The PostgreSQL system utilizes a feature called vacuuming to remove deleted records Vacuuming the database is described in detail a little later in the Autovacuum Parameters section When the PostgreSQL system initiates a vacuum process, the system tracks how many system resources are consumed by the vacuum You can control how many resources the system allows the vacuum process to take before limiting the process by using these feature values: vacuum_cost_delay = 0 The length of time in milliseconds that the vacuum process will sleep if it exceeds its process limits The default value of 0 disables this feature vacuum_cost_page_hit = 1 The estimated cost for vacuuming a buffer found in the shared buffer cache vacuum_cost_page_miss = 10 The estimated cost for vacuuming a buffer that has to be read from disk vacuum_cost_page_dirty = 20 The estimated cost for modifying a block that was previously clean vacuum_cost_limit = 200 The total cost that will cause a vacuum process to sleep The PostgreSQL background writer process ensures that memory buffers containing transaction data are written to the hard disks as soon as possible This group of feature values can be fine-tuned by advanced administrators to determine exactly how often the memory buffers are written bgwriter_delay = 200 Specifies the delay in milliseconds between background writer process runs bgwriter_lru_percent = 10 The percentage of buffers examined in one background writer process
