  • 创建DB 2数据库缓冲空间,使用大于4k的页面大小。

    Create DB2 database, buffer pool, and tablespace with more than 4k.

    youdao

  • 尝试减少这两个数据库缓冲大小

    Attempt to reduce buffer pool sizes for both databases. Or.

  • 生成缓冲空间数据库分区信息

    Generate buffer pool, tablespace, and database partition group information.

    youdao

  • 确定数据库缓冲大小是否BUFFPAGE参数所决定,请运行

    To determine whether the BUFFPAGE parameter is in use for buffer pool size of database, run.

  • 加载驱动程序使用连接器中的数据构建 64k缓冲以便发送Teradata数据库

    The load driver will use the data from the connector and build 64k buffer to be sent to the Teradata database.

    youdao

  • NPAGES值为-1时,缓冲大小就是数据库配置中的BUFFPAGE参数确定的。

    When NPAGES has value of -1, the buffer pool size is determined by the BUFFPAGE parameter in the database configuration. For example.

  • 优化IBMDB2数据库缓冲

    Tuning IBM DB2 database buffer pools

    youdao

  • 特别是要避免没有缓冲的、生命期短的数据库连接

    Specifically, avoid non-pooled short-lived database connections.

    youdao

  • 创建空间时,可以特定缓冲(数据库缓存)关联起来,并关联特定的容器

    When you create a table space, you can associate it with a specific buffer pool (database cache) as well as to specific containers.

    youdao

  • 如果数据库没有启动那么不能连接数据库,也就不能更改缓冲大小

    If the database is not started, you cannot connect to the database and change the buffer pool sizes.

    youdao

  • 意味着DB 2无法启动数据库因为数据库至少必须缓冲

    That means DB2 cannot start the database, because a database must have at least one buffer pool.

    youdao

  • 如果超过这个缓冲大小数据库服务器会丢弃保存数据

    If this buffer size is exceeded, the database server discards saved data.

    youdao

  • 显然随着数据库服务器物理内存使用,缓冲命中率对于数据库性能而言始终比较好

    Obviously, with availability of physical memory on the database server, a high buffer pool hit ratio is always better for your database performance.
