CPU If one is looking out for a HiDef gaming Media PC, would a server process hold any advantage over desktop. HSQLDB can be run in a number of different ways. In general these are divided into Server Modes and InProcess Mode also called Standalone Mode. Managing Oracle Database Processes. This chapter describes how to manage and monitor the processes of an Oracle Database instance and contains the following topics. QA for database professionals who wish to improve their database skills and learn from others in the community. Advantage Database Server 10 Serial Number' title='Advantage Database Server 10 Serial Number' />Phone Secrets and i. Pad Secrets and i. Pod Touch Secretsi. Phone, i. Pad, and i. Pod Touch Secretshttps www. Uz. 8ng. Gb. Wu. U. The purpose of this webpage is to provide information a majority are secret or are hard to find on the i. Phone, i. Pad, and i. Pod touch. It will mainly concentrate on the more feature rich i. Phone, but sometimes information on the i. Pad and i. Pod Touch will be added if it is not too distracting. If you think you know all there is to know about the i. Phone, i. Pod Touch, or i. Pad, read the following and you might learn a thing or two that you didnt know before. It is updated as new information is uncovered in the public, so visit often if you wish to keep up to date on the latest secrets. Please link to this webpage rather than copy the contents. And do remember that the ads support this page so visit them if they interest you. Note that this page is part of a collection of secrets to various hardware. Feel free to read other technology SECRETS by visiting the menu at the top of this page. First Apple Store in Hong Kong. Phone Model Differences. The following chart describes the basic differences between various i. Phone and i. Pod Touch model numbers. Pod Classic, i. Pod Mini, i. Pod Photo, i. Pod Video, i. Pod Shuffle, and i. Pod Nano are not included because they are not able to run the same software as i. Phone and i. Pod touch which have binary code compatibility. What this means is that compiled code can run on i. Phone or i. Pod Touch unmodified and on later device versions, as long as you are able to download and install them. Note that special applications that makes use of hardware on newer versions of the i. Phone like the digital compass capability of the i. Phone 3. GS would not work on earlier models. For the i. Pad, i. Pad 3. G refers to the i. Pad Wi Fi 3. G model. For quick identification purposes, the i. Pod Touch will have 1. G, 2. G, or 3. G to designate the i. Pod Touch generation 1. G first generation 2. G second generation etc. These quoted abbreviations have nothing to do with the 3. G designation used to indicate cellular technology generation on the i. Phone 3. G. Applications on i. Pod Touch 1. G, 2. G, and 3. G are not able to use any cellphone hardware capabilities at all. For the original i. Phone, it will sometimes be identified as i. Phone 2. G since it uses GSM, a cellular 2. G standard. In other words, quoted designations are not official product names from Apple unlike non quoted ones, but are used to identify your device. The i. Pad is like a big i. Pod Touch, but has some borrowed features from the i. Phone like the digital compass and cellular 3. G capability. Visually, all i. Pod Touch models have an aluminum back with a small plastic covering in the top left corner. Pod Touch 1. G has squarish covering, while the i. Pod Touch 2. G3. G have an oval covering. Only the i. Phone 2. G has an aluminum back without the top left plastic covering. Both i. Phone 3. G and 3. GS have plastic backs. The i. Phone 44 CDMA have a aluminosilicate glass back. The main physical differences between the i. Phone 4 and the i. Phone 4 CDMA are the appearances of extra linear gaps located on the outer metal band in between the two glass sheets. The extra air gaps lessens the possibility for signal interference caused by your fingers by separating the different antennas from each other. The Model Number is located on the back of the device. The i. Phone 2. G also includes the serial number and IMEI number on the back of the phone. Model. Common Name. FlashGBDRAMARM CPUPower. VRGPUResolution. Wi Fi. Bluetooth. Camera. Cellular Types.

This section discusses how to enable shared server and how to set or alter shared server initialization parameters. It contains the following topics Initialization Parameters for Shared Server. The following initialization parameters control shared server operation SHAREDSERVERS Specifies the initial number of shared servers to start and the minimum number of shared servers to keep. This is the only required parameter for using shared servers. MAXSHAREDSERVERS Specifies the maximum number of shared servers that can run simultaneously. SHAREDSERVERSESSIONS Specifies the total number of shared server user sessions that can run simultaneously. Setting this parameter enables you to reserve user sessions for dedicated servers. DISPATCHERS Configures dispatcher processes in the shared server architecture. MAXDISPATCHERS Specifies the maximum number of dispatcher processes that can run simultaneously. This parameter can be ignored for now. It will only be useful in a future release when the number of dispatchers is auto tuned according to the number of concurrent connections. CIRCUITS Specifies the total number of virtual circuits that are available for inbound and outbound network sessions. Memory Management for Shared Server. Shared server requires some user global area UGA in either the shared pool or large pool. For installations with a small number of simultaneous sessions, the default sizes for these system global area SGA components are generally sufficient. However, if you expect a large number of sessions for your installation, you may have to tune memory to support shared server. See the Configuring and Using Memory section of Oracle Database Performance Tuning Guide for guidelines. Enabling Shared Server. Shared server is enabled by setting the SHAREDSERVERS initialization parameter to a value greater than 0. The other shared server initialization parameters need not be set. Because shared server requires at least one dispatcher in order to work, a dispatcher is brought up even if no dispatcher has been configured. Dispatchers are discussed in Configuring Dispatchers. Psp 2 Highly Compressed. Shared server can be started dynamically by setting the SHAREDSERVERS parameter to a nonzero value with the ALTER SYSTEM statement, or SHAREDSERVERS can be included at database startup in the initialization parameter file. If SHAREDSERVERS is not included in the initialization parameter file, or is included but is set to 0, then shared server is not enabled at database startup. Note. If SHAREDSERVERS is not included in the initialization parameter file at database startup, but DISPATCHERS is included and it specifies at least one dispatcher, shared server is enabled. In this case, the default for SHAREDSERVERS is 1. If neither SHAREDSERVERS nor DISPATCHERS is included in the initialization file, you cannot start shared server after the instance is brought up by just altering the DISPATCHERS parameter. You must specifically alter SHAREDSERVERS to a nonzero value to start shared server. Note. If you create your Oracle database with Database Configuration Assistant DBCA, DBCA configures a dispatcher for Oracle XML DB XDB. This is because XDB protocols like HTTP and FTP require shared server. This results in a SHAREDSERVER value of 1. Although shared server is enabled, this configuration permits only sessions that connect to the XDB service to use shared server. To enable shared server for regular database sessions for submitting SQL statements, you must add an additional dispatcher configuration, or replace the existing configuration with one that is not specific to XDB. See Configuring Dispatchers for instructions. Determining a Value for SHAREDSERVERSThe SHAREDSERVERS initialization parameter specifies the minimum number of shared servers that you want created when the instance is started. After instance startup, Oracle Database can dynamically adjust the number of shared servers based on how busy existing shared servers are and the length of the request queue. In typical systems, the number of shared servers stabilizes at a ratio of one shared server for every ten connections. For OLTP applications, when the rate of requests is low, or when the ratio of server usage to request is low, the connections to servers ratio could be higher. In contrast, in applications where the rate of requests is high or the server usage to request ratio is high, the connections to server ratio could be lower. The PMON process monitor background process cannot terminate shared servers below the value specified by SHAREDSERVERS. Therefore, you can use this parameter to stabilize the load and minimize strain on the system by preventing PMON from terminating and then restarting shared servers because of coincidental fluctuations in load. If you know the average load on your system, you can set SHAREDSERVERS to an optimal value. The following example shows how you can use this parameter Assume a database is being used by a telemarketing center staffed by 1. On average, each agent spends 9. To keep the shared servers from being terminated as agents talk to customers and then spawned again as agents access the database, a DBA specifies that the optimal number of shared servers is 1. However, not all work shifts are staffed at the same level. On the night shift, only 2. Since SHAREDSERVERS is a dynamic parameter, a DBA reduces the number of shared servers to 2. Decreasing the Number of Shared Server Processes. You can decrease the minimum number of shared servers that must be kept active by dynamically setting the SHAREDSERVERS parameter to a lower value. Thereafter, until the number of shared servers is decreased to the value of the SHAREDSERVERS parameter, any shared servers that become inactive are marked by PMON for termination. The following statement reduces the number of shared servers. ALTER SYSTEM SET SHAREDSERVERS 5. Setting SHAREDSERVERS to 0 disables shared server. For more information, see Disabling Shared Server. Limiting the Number of Shared Server Processes. The MAXSHAREDSERVERS parameter specifies the maximum number of shared servers that can be automatically created by PMON. It has no default value. If no value is specified, then PMON starts as many shared servers as is required by the load, subject to these limitations The process limit set by the PROCESSES initialization parameterA minimum number of free process slots at least one eighth of the total process slots, or two slots if PROCESSES is set to less than 2. System resources. Note. On Windows NT, take care when setting MAXSHAREDSERVERS to a high value, because each server is a thread in a common process. The value of SHAREDSERVERS overrides the value of MAXSHAREDSERVERS. Therefore, you can force PMON to start more shared servers than the MAXSHAREDSERVERS value by setting SHAREDSERVERS to a value higher than MAXSHAREDSERVERS. You can subsequently place a new upper limit on the number of shared servers by dynamically altering the MAXSHAREDSERVERS to a value higher than SHAREDSERVERS. The primary reason to limit the number of shared servers is to reserve resources, such as memory and CPU time, for other processes. For example, consider the case of the telemarketing center discussed previously The DBA wants to reserve two thirds of the resources for batch jobs at night. He sets MAXSHAREDSERVERS to less than one third of the maximum number of processes PROCESSES.
