所有这8个段(2gb)可能都被用于数据库共享内存。
Potentially, all 8 segments (2 GB) can be used for database Shared memory.
QueryOpen代理的以下LotusScript代码段执行对approver数据库的查找。
The following LotusScript code fragment of the QueryOpen agent performs a lookup to the approver database. It populates the RETENTION_ERRMSG field if the approver is no longer found.
数据库没有彻底关闭(在回滚段中有活动的事务)。
The database was not cleanly shut down (there are active transactions in the rollback segments).
如果需要，创建另一个新的数据库以存储整个一年或者特定时间段内的假期信息。
If needed, create another new database to store holiday information for an entire year or for a specified time duration.
如果需要同步数据库，那么需要在这一阶段要有所计划。
If you require the databases to be synchronized then you must plan for this process.
注意：对于下面的每种配置，DB 2将从数据库共享内存中拿出一个段，这个段始于段b。
Note: DB2 will take away one segment from the database Shared memory for each of the following configurations, starting from segment b.
假如有三位开发人员正在使用代码段基址，而且他们使用的是本地的数据库。
Imagine that three developers work on the code base and that they each use their local database.
这样便迫使DB2将段E用于本地连接，从而为数据库共享内存空出一个段。
This forces DB2 to use segment E for local connections, thus freeing one segment for database shared memory.
在许多情况下，事务会话会持续较长一段时间，占用着数据库连接，直到完成。
In many cases, the session of transactions can take a good while, holding the database connection until complete.
现在，在最终提交该事务之前，客户机通知参与的数据库准备提交(第1阶段)。
Now, before the transaction is finally committed the client advises the participating database to prepare the commit (Phase 1).
