under the same directory as/usr/local/pgsql/data/base (environment variable pgdata specifies The base directory of the path). If the database name parameter is omitted, the user name is automatically used as the database name. For example, a database named DB1 will be saved in the/USR/LOCAL/PGSQL/DATA/BASE/DB1 directory. You can also use the initlocation command to specify a different location: $ initlocation/pgsql/data $ Export Pgdata2=/pgsql/data $ createdb-d PGDATA2 DB2 The database DB2 wil

In addition, PostgreSQL version 6.4 can specify the text encoding when establishing the database: createdb-e "character encoding" "character encoding" see Configure, Initdb.

Recently wrote a driver to virtual a file into SCSI DISK. The driver is essentially an HBA driver. When driving performance testing, it is found that IO performance is very low, only achieves 4mb/s throughput when a large amount of data is written, and has high performance when writing a small amount of data. The drive IO model is shown in the following illustration: A print analysis of the Queuecommand process in the driver found that the SCSI mid

unix| Backup SCO installation and backup of the tape drive under UNIX (i) Use tape drive to back up data for work reasons. In the implementation process summed up a number of experience for your reference. The server is IBM PC Server 250 (Dual-machine + array cabinet), the operating system is SCO UnixWare 7.1.1, because it is the financial system, also installed a dual-computer software GDS, SYBASE11.9.4 and financial system applications are installed on the disk array, there are now two appli

performance advantage." For example, the more powerful the server is, the more we have the opportunity to bring a better product to our customers, however, the increasing number of server processor cores also makes it possible for terminal user to run more virtual machines on each server using the same number of devices, which can be reduced by the change in the sales performance. If we do not make adequate adjustments to the new technology development trend for solutions and products, it is li

familiar with these protocols, you do not have to worry about them. We will discuss them in future articles. Of course, the NAS mentioned above cannot be sold. Most enterprises choose NAs from companies such as EMC and netapp because they have features that are hard to implement on common file servers. First, let's give a brief introduction. Girls should polish their eyes to see how different things are from ordinary it guys. I. High Performance. If

?As we all know, IC chip packaging SMD and double-row in the sub-type. It is generally believed that the difference between SMD and double-row is mainlyIt is different in volume and welding method, which has little effect on system performance. actually otherwiseEvery trace on the PCB has an antenna effect. Each component on the PCB also has an antenna effect, the larger the conductive part of the component, the dayThe stronger the line effect. Therefore, the same type of chip, package size is s

construction are required, the power supply layer and ground layer are usually used to avoid the impact of transmission signals on the signal layer, and can be used as a shield for the signal layer. Wire rear circuit testTo ensure that the line works properly after the wire, it must pass the final detection. This check can also check whether there is an incorrect connection, and all the connections are taken according to the overview. Create an archiveBecause there are currently many CAD

are servers, networks, and messy devices in the IDC. Then there is wiring, device installation, debugging, testing, acceptance, and so on. If the other party does not have a professional person to perform technical maintenance for the IDC room, we can do it and pay for it. This is DC outsourcing and can also be understood as a third-party service.We do not outsource Financial IT, software or website services. Most of them are background tasks. For example, maintenance for IBM small machines,

quickly scale their IT operations to respond to sudden change demands while maintaining high-speed performance. Second, they can move non-sensitive features to the public domain to reduce their need for their on-premises private clouds.3. Cost-effectivenessOne big advantage of hybrid cloud is that it lowers costs. Because the hybrid cloud is configured to use both public and private clouds, it allows users to access large-scale economic benefits, such as centralized management, without exposing

, which implements integer and fixed point types of any length. These freely accessible types have a series of advantages, including unified and well-defined semantics, as well as the runtime speed comparable to the built-in data types in C/C ++. Compared with the corresponding types in EMC, the runtime speed exceeds 10 times. These data types can be used in any program that complies with the C ++ or EMC sp

tools to create storage volumes and allocate addresses or SCSI Luns. If some entities do not have Luns, The LUN mask hides the LUN. The LUN binding only associates the LUN with the global ID of the HBA in the server. When the LUN mask and binding are completed, storage experts should go deep into the vswitch, create a region, and only allow dedicated adapters to communicate with specific storage ports. "In fact, the vswitch can enhance the LUN mask a

, many small and medium enterprises prefer to use iSCSI storage for cost effectiveness.It is very important to distinguish between SCSI devices and FC Optical Fiber devices. FC Optical Fiber devices simulate the abstract devices of one or more SCSI devices at the bottom layer of storage virtualization, and do not have real SCSI devices, it is simulated through the SCSI protocol.GNBD (Global Network Block Device) Global Network Block devices are similar to iSCSI storage architecture, but data tra

technology, no MPIO. HBA is a hardware physical block used to connect disk drives and other storage devices. The HBA manufacturer creates a micro-port driver connected to STORPORT. SYS. Most HBA drivers report communication errors to Application Event Logs. Ideally, the entire chain of this event takes no more than 20 milliseconds. Performance is affected by mul

Directory Definition UML Participants Example Definition: The Singleton Mode means that there is only one instance. The Singleton mode ensures that a class has only one instance, and the instance is self-instantiated and provided to the entire system. This class is called a singleton class. Application: Each computer can have several printers, but only one printer spooler can be used to prevent two print jobs from being output to the printer at the same time. Each
