results of a query, and if it's not mistaken, Oracle uses a greedy algorithm for allocating disk space (memory), if the last disk space consumption reaches 1GB , the temp table space is 1GB, and if there is growth, then the temporary table space remains at one of the largest caps. An analysis of the explosion of Oracle temporary table space may be caused by several reasons. 1. There is no upper limit for t

file (the default setting is 1GB). Before the amount of information in the previous binary log file exceeds this maximum length, the MySQL server automatically provides a new binary log file to continue. Binlog-do-db = dbname Only the changes in a given database are recorded in binary log files, and the changes in other databases are not documented. If you need to document the changes in multiple databases, you must set up the configu

Yesterday in the test to find a very strange problem: The query module in the program to do the query, the beginning of a very fast, but after a period of time after the slow, and finally simply error, do not work. In the process of debugging, found that the Oracle temporary table space soared, reached dozens of GB, the session in Oracle tracking, found that disk space is still being consumed, almost every 5s, temporary table space will grow about 500MB, The final error should be due to the fact

The Oracle temporary table space is used primarily for querying and storing buffer data. The primary reason for temporary table space consumption is the need to sort the intermediate results of a query. Restarting a database frees up temporary tablespace, and if you can't restart the instance and keep the problem SQL statement executing, the temp table space is growing. The Oracle temporary table space is primarily used for querying and storing buffer data. The primary reason for temporary table

of disk space, Oracle is using a greedy algorithm, if the last disk space consumption reached 1GB, then the temporary table space is 1GB. That is, the size of the current temporary tablespace file is the maximum size of a temporary table space used historically. Primary role of temporary tablespace: index create or rebuild order by or group by DISTINCT operations Union or intersect or minus Sort-merge join

the internal core architecture will shrink. The most important of these is the table that Windows uses to manage physical memory, and when you shrink the core memory space to 1G, you limit the size of the table so that you can manage only the maximum 16GB of physical memory. For example, if your application is running on a server with 64GB of physical memory and you add/3GB parameters at startup. You can only access 25% of the total memory space-the rest of the 48GB of memory is inaccessible to

For example, I attach disk for 1TB, is actually to this 1TB copy 1GB content. Azure will actually

A Pentium4 machine, the use of 80GB hard drive, start Windows XP system, has been stuck in the start screen, hard drive constantly "ka" rang, apparently hard drive out of the problem. This hard drive is divided into C (20GB), D (30GB), E (30GB) three partition, where C disk is system and application software, D and E disk is user data. According to this situation, i

least 4GB of memory. The problem is that the 32-bit version, like Vista and Win 7, can only be about 3GB of memory. In contrast, 64-bit Windows can take advantage of up to 192GB of memory and can use a memory map that replaces the BIOS's capabilities, allowing the operating system to actually use the full 4GB. Therefore, if you install Win7 x64, you will not waste 1GB of memory for a machine with 4GB of memory. Personally, 3GB is not enough for every

Android's charm is not just in mobile phones or tablet PCs, you can even get the entertainment experience of Android by using a USB disk that is sized to connect to a TV or a monitor with an HDMI interface. Over the past year, we've seen the rapid development of such products, from MK802 to dual-core RK3066 with Android 4.0 systems and single core processors, and now the first quad-core processor Zealz GK802 has come to us. The Zealz GK802 also has a mini volume and delivers a more high-performa
