Active Session History (ASH) performed an emergency flush

Active Session History (ASH) performed an emergency flush. This may mean that ASH is undersized. If emergency flushes are a recurring issue, you may consider increasing ASH size by setting the value of _ASH_SIZE to a sufficiently large value. Currently, ASH size is 4194304 bytes. Both ASH size and the total number of emergency flushes since instance startup can be monitored by running the following query:


SQL> select total_size,awr_flush_emergency_count from v$ash_info;

TOTAL_SIZE AWR_FLUSH_EMERGENCY_COUNT

SCN may jump in a distributed transaction with dblink

在分布式事务环境中数据库的SCN可能瞬间暴增,这种行为被称作SCN jump in distributed transaction,注意这种现象是正常的。在发生分布式事务的2个数据库中,SCN较低的DB会将SCN和较高的那个数据库同步,这有时候会造成我们的一些误解认为可能是Hot backup等操作引起了SCN的猛增。

我们来具体看一下这种现象:

由于这种SCN跳跃可能引起ORA-600 [2252]内部错误,相关的bug case.

Know more about redo log buffer and latches

1.
The Total size of the log buffer is determined by LOG_BUFFER parameter.

2.
Only Server process may pin a data block in exclusive mode.

3.
LGWR writes to the redo log files when:

  • The redo log buffer is 1/3 full.
  • 1 MB of data have been written to the redo log buffer.
  • A 3-second time-out occurs.
  • commit!
  • before dbwr write out dirty buffers
  • A thread is closed

 

4.
the correct sequence for the LGWR algorithm is :

  1. Acquire the redo writing and redo allocation latches
  2. determine the buffer to write out
  3. Release the redo allocation latch
  4. determine how many writes are required

 

5.
In Oracle8i, the redo copy latch is always acquired regardless of the redo size.

Because the parameter LOG_SMALL_ENTRY_MAX_SIZE is obsolete, a redo copy latch is always acquired.

6.
Three most relevant redo events under normal operations:

  • Log file parallel write
  • Log buffer space
  • Log file sync

 

7.
relevant redo statistics and their purpose

  • REDO writes                                                 === Number of times the log buffer is written
  • redo blocks written                                === Number of times the log buffer is written
  • redo write time                                          === Total time required to write all the redos to disk
  • redo buffer allocation retires         === Total number of retries necessary to allocate space in the redo buffer

 

8.
Log buffer contention is typically indicated by Redo buffer allocation retries .

The buffer allocation retries indicates that a process has to continually try to allocate buffers that are not available

9.
Redo buffer allocation retries can be gathered by querying the name and value columns from V$ dynamic views:
V$sesstat
V$sysstat

10.
Stripe the redo log files across physical disks will help flush the redo buffer faster.

The redo log file write batch is 128K, so striping the redo logs across 8 disks with a stripe size of 16K could improve the write time by as much as 75%.

11.
The number of redo copy latches can be defined by setting _Log_simultaneous_copies .

The parameter begins with an underscore because in 8i it is a hidden parameter.

12.
The purpose of the redo writing latch is to: Prevent multiple processes from posting
LGWR when there is no space in the buffer .

The redo writing latch frees space in log buffer and does not want
processes writing to the buffer while space is being freed

13.
_log_io_size is set to reduce contention for the redo writing latch.

But notice that it is a hidden parameter. This is the number of used redo blocks that will automatically initiate a log write.

14.
A standby database must be refreshed following a nologging operation.

When nologging occurs, the redo logs of the standby database are not written to.

15.
log_small_entry_max_size is used to determine if a redo copy latch is required based upon the redo entry size,

however, this parameter is obsolete in Oracle8i, as a copy latch is always acquired.

_log_simultaneous_copies determines the number of redo copy latches to allocate.

Note that this is a hidden parameter in Oracle8i because it is not recommended to have more than one copy latch.

log_checkpoint_interval determines the need for a checkpoint.

如何设计分区索引

通过下图定义的规则,可确定分区索引类型:
design-partition-index

Hash Global分区索引介绍
HASH-Partitioned Global索引是Oracle 10g开始提供的新特性。而在以前的版本中
,Oracle只支持Range-Partitioned Global索引。HASH-Partitioned Global索引的好处如下:
比Range-Partitioned Global索引易于实施。HASH-Partitioned Global索引是根据
索引字段值,通过Oracle内部的HASH算法自动均匀散列到定义的分区中。而
Range-Partitioned Global索引需要根据索引字段值的范围进行分区,因此实施和
维护的难度都大。
HASH-Partitioned Global索引适合于在并发量、吞吐量很大的交易系统(OLTP)
中,对某些字段的访问冲突。尤其是sequence字段值。
HASH-Partitioned Global索引适合于大批量的数据查询。HASH-Partitioned Global索引不仅可以提供分区之间的并行查询,
而且在分区内也可进行并行查询的处理。
建立分区索引必须指定表空间,并且指定的表空间要与数据表空间分开,
这样便于管理,同时尽可能分开索引和数据的IO访问,提高效率
