在oracle 12c中对象名长度已经变为128,但是dul依旧不能支持列长度，既然作者已经在init.dul的Compatible参数曾增加了对12c的支持,那对这样明显的bug应该在不久的将来即可修复。当然这个问题,可以通过一些人工技巧绕过去

_use_single_log_writer和_max_outstanding_log_writes

SCALABLE LGWR是12cR1中引入的一个令人激动的特性，这是由于在OLTP环境中LGWR写日志往往成为系统的主要性能瓶颈，如果LGWR进程能像DBWR(DBW0~DBWn)那样多进程（LGNN）写出redo到LOGFILE那么就可能大幅释放OLTP的并发能力，增长Transcation系统的单位时间事务处理能力。这里在12.2版本中进行测试，确定_use_single_log_writer和_max_outstanding_log_writes参数对于SCALABLE LGWR特性的影响

_use_single_log_writer和_max_outstanding_log_writes默认值

lg进程数量
这里可以看出来，有一个lgwr进程，两个lg进程和_max_outstanding_log_writes参数配置匹配

[oracle@ora1221 ~]$ ps -ef|grep ora_lg
oracle    49790      1  0 10:32 ?        00:00:00 ora_lgwr_orcl12c2
oracle    49794      1  0 10:32 ?        00:00:00 ora_lg00_orcl12c2
oracle    49798      1  0 10:32 ?        00:00:00 ora_lg01_orcl12c2

修改_max_outstanding_log_writes参数
通过修改_max_outstanding_log_writes参数为4，发现lg进程数量也变为了4，证明_max_outstanding_log_writes进程决定lg进程数量

修改_use_single_log_writer参数
通过测试_use_single_log_writer参数修改，我们可以确定_use_single_log_writer修改为true后，数据库恢复到12c之前的lgwr管理方式

从这里可以确定_use_single_log_writer确定是否启用SCALABLE LGWR(多个lg子进程),_max_outstanding_log_writes确定lg进程个数

Errors in file /opt/app/oracle/diag/rdbms/xifenfei/xifenfei/trace/xifenfei_p009_13814.trc  (incident=165906):
ORA-00600: 内部错误代码, 参数: [kdBlkCheckError], [26], [950417], [18025], [], [], [], [], [], [], [], []

这些错误是由于数据库block逻辑异常导致,错过参数含义
在10g中ORA-600 kddummy_blkchk 在11g中ORA-600 kdBlkCheckError

ARGUMENTS:
Arg [a] Absolute file number
Arg [b] Bock number
Arg  Internal error code returned from kcbchk() which indicates the problem encountered.
See Note 46389.1 for details of block check codes.

根据QREF kddummy_blkchk / kdBlkCheckError Check Codes Listing (Full) (Doc ID 1264040.1)分析
这里的18025是代码的KCBTEMAP_EC_START + KTS4_EC_SBFREE部分异常，主要表现在Incorrect firstfree or nfree 可以通过设置一些参数进行屏蔽

在恢复过程中还有其他错误

Non-fatal internal error happenned while SMON was doing logging scn->time mapping.

通过整体分析错误主要是由于undo异常导致,通过设置_corrupted_rollback_segments设置db_block_checking等相关参数,清理SMON_SCN_TIME等操作数据库没有其他异常报错,让其通过逻辑方式重建库

12.1中出现大量Result Cache: RC Latch处理

昨天有个朋友找到我说他们的12.1的库在业务高峰期非常慢，希望我们给予优化支持,经过awr分析，定位到问题为latch free问题,具体定位为:Result Cache: RC Latch.
优化之前awr部分信息
awr整体负载情况，证明当前这个库已经比较忙，业务反馈很慢
awr1

addr信息和top wait信息，确定是latch free问题比较突出
awr2
awr3

latch信息统计和ash信息，找出来突出的latch,定位为Result Cache: RC Latch引起该问题
awr4
awr5

补充大量异常sql
awr6

类似sql语句

SELECT /* DS_SVC */ /*+ dynamic_sampling(0) no_sql_tune no_monitoring optimizer_features_enable(default) no_parallel */
 SUM(C1) FROM (SELECT /*+ qb_name("innerQuery") INDEX_FFS( "ACCOUNT" "ACC_USER_ID") */
1 AS C1 FROM "ACCOUNT" SAMPLE BLOCK(39.3701, 8) SEED(1) "ACCOUNT" WHERE ( "ACCOUNT".USER_ID IS NOT NULL)) innerQuery

查询mos发现
The cause of this issue is automatic dynamic statistics which is enabled by default in 12c automatically decides whether dynamic statistics are useful and which statistics level to use for all SQL statements. It collects dynamic statistics when the optimizer deems it necessary.
When Automatic Dynamic Sampling is used for the SQL statements, it can decide, based upon these statistics, that a better response time could be achieved by using the result cache for those queries. This can cause heavy usage of the result cache leading to the contention on latch free for “Result Cache: RC Latch”.
也就是说,12c在自动采样有改进，而且默认使用result cache特性，从而引起该问题，即使你设置了 RESULT_CACHE_MODE = MANUAL，依旧会有大量动态采样引起 Result Cache: RC Latch，彻底解决给问题就是通过隐含参数禁止Automatic Dynamic Statistics使用result cache

alter system set "_optimizer_ads_use_result_cache" = FALSE;

设置该参数之后效果
这里看，通过上述处理后，系统db time 大量减少，业务反馈已经运行正常
hawr1

latch free和Result Cache: RC Latch已经基本上消失
hawr2
hawr3
hawr4

当然这个异常是由于动态采样导致,可以通过收集数据库统计信息，设置动态采样级别，也可以从一定程度上缓解该情况.

分析drop col对于数据存储块做了什么

oracle 的alter table drop col具体内部是对于数据存储块操作的,如果drop col之后dul之类的工具是否可以恢复,这里我通过具体测试,结合bbed,dump block等方法来说明该问题
1.创建测试表，并写入硬盘

SQL> create table xff.t_xifenfei as select object_id,owner,object_name from dba_objects;
Table created.
SQL> desc xff.t_xifenfei
 Name                                      Null?    Type
 ----------------------------------------- -------- ----------------------------
 OBJECT_ID                                          NUMBER
 OWNER                                              VARCHAR2(30)
 OBJECT_NAME                                        VARCHAR2(128)
SQL> alter system checkpoint;
System altered.
SQL> alter system checkpoint;
System altered.

2.找出来测试表一个block分析drop col对于存储的影响

SQL> select   rowid,
  2  dbms_rowid.rowid_relative_fno(rowid)rel_fno,
  3  dbms_rowid.rowid_block_number(rowid)blockno,
dbms_rowid.rowid_row_number(rowid) rowno,object_id
  4    5  from xff.t_xifenfei where rownum<5;
ROWID                 REL_FNO    BLOCKNO      ROWNO  OBJECT_ID
------------------ ---------- ---------- ---------- ----------
AAAZ9wAAEAAAJojAAA          4      39459          0         20
AAAZ9wAAEAAAJojAAB          4      39459          1         46
AAAZ9wAAEAAAJojAAC          4      39459          2         28
AAAZ9wAAEAAAJojAAD          4      39459          3         15

3. dump block，并且记录该block 1,2,和最后一条记录

SQL> oradebug setmypid
Statement processed.
SQL> alter system dump datafile 4 block 39459;
System altered.
SQL> oradebug TRACEFILE_NAME
/home/u01/diag/rdbms/orcl/orcl/trace/orcl_ora_14069.trc
block_row_dump:

col  1: [ 3]  53 59 53
col  2: [10]  49 5f 4a 4f 42 5f 4e 45 58 54

4. 使用bbed查看该block 1,2,和最后一条记录

[oracle@localhost ~]$ bbed password=blockedit blocksize=8192 filename=/usr/local/oradata/qsng/users01.dbf

5. 删除中间列，并且写入硬盘

SQL> ALTER TABLE XFF.T_XIFENFEI DROP COLUMN owner;
Table altered.
SQL> alter system checkpoint;

SQL> /

6. 查询确定相同行所在block没有发生改变

  2  dbms_rowid.rowid_relative_fno(rowid)rel_fno,
  3  dbms_rowid.rowid_block_number(rowid)blockno,

AAAZ9wAAEAAAJojAAD          4      39459          3         15

7. drop col之后dump block继续分析

SQL>  select value from v$diag_info where name='Default Trace File';

通过上述测试可以得出如下结论:
1. drop col是真的把对应列存储在block中的内容除掉,而且把后面的列的内容前移了,并且以前多于的内容(因为一行内容前移,后面就出现空闲记录不设置为空,而就是最初内容,下次如果行长度发生改变的时候使用,就和类似update把列修改短了一样)
2. drop col只是导致一行的长度变短,但是每行的偏移量未发生改变,也就是说,每行所在的偏移量没有改变,drop col之后,每行后面多了一些空闲空间
3. 根据上面分析的原理,drop col 是真的从block内部把这一列的数据使用后面列的数据覆盖了,因此从原理上而言,dul无法恢复drop col的数据(最后一列有可能可以恢复,因为他不会被覆盖),对于drop col,只能是通过备份不完全恢复,全库闪回,dg延迟应用等方法解决

ADHU(ASM Disk Header Utility)—asm disk header备份恢复工具

adhu（ASM Disk Header Utility）作为oracle asm中和kfed,amdu齐名的asm三大恢复神器之一,没有被oracle大力推广(属于内部工具),随着kfed功能增强和asm disk header自动备份功能的完善,adhu oracle基本上停止的开发支持,可以用来作为10.2.0.5之前asm版本的磁盘头保护工具
adhu预览
这里可以通过shell封装的utildhu调用adhu程序,实现更加人性化和自动化操作,它含有install,check,repair三个命令参数.

Usage: utildhu install/check/repair [device name]
$utildhu install
Will gather a list of member ASM disks and create
the backup directory  ./HeaderBackup
The ./HeaderBackup directory will contain the
backup header of every asm disk in this database
$utildhu  check
Will run /tmp/adhu/adhu for every disk discovered by
$utildhu install and will email recipients configured
in RECIPIENTS if there are errors in the disk header
It is hoped that the user will enter valid RECIPIENT
email addresses, and will place this utility in $ORA_ASM_HOME
$utildhu  repair <device name>
Will repair the device provided using the backup
header blocks that have been copied previously.
This does assume that you have backup header blocks
in ./HeaderBackup

adhu直接使用
adhu [-dir dirname ] [-repair] [-quiet] [-readonly] [-syslog mask ] devname
默认情况下adhu将disk header备份为当前目录下的备份文件。使用-dir选项可以指定存放的目录。
当需要使用adhu去修复一个损坏的asm disk header时使用-repair 选项。
-quiet 选项将过滤所有正常的输出信息，若执行成功则不打印任何输出。
-readonly选项以只读方式来打开disk device，这样备份block将不被写入，而备份文件将在可能的情况下写入。
-syslog选项控制是否写出结果到系统日志和标准输出。
devname代表为asm disk的设备文件，asm头的备份文件将以该device name为基础，并存放在当前目录或者-dir指定的目录。

通过观察这段日志,基本上可以发现主要是FILE 45,虽然提示坏块但是最终验证确定为正常块（类似：Reread (file 45, block 7836) found valid data),这里主要是file 5，报了大量的ORA-600[3020].

修改11.2 RAC 的 SCAN IP

在某些情况下,由于是C/S架构,从以前的单机系统迁移到现在11.2的rac中,如果修改客户端ip地址工作量太大,而且也不现实,一般建议直接修改scan ip地址和以前一样,从而实现业务直接访问scan ip实现应用不用一个个单独配置.这里通过简单演示,实现修改scan ip的过程(网段不变),主要是把scan名字为scan-xff的ip地址从192.168.137.245修改为192.168.137.248
查看当前scan ip信息

这里发现修改scan ip之后,scan listener没有正确或者到监听的动态注册信息,哪怕人工执行了alter system register;也不行.

通过重启数据库,解决修改scan ip后的动态监听注册问题
