oracle数据库升级到12c版本新特性
时间：2022-06-29 09:34:51 编辑：袖梨 来源：一聚教程网
Mike Dietrich有一篇600多页的ppt，叫『Upgrade, Migrate & Consolidate to Oracle Database 12c』。在这个ppt里面，有一些是标记了“NEW”了的表示12c的新特性、新行为。 （其实升级到11g的时候，也有一篇差不多类似的400多页的ppt，被oracle售前广泛应用。）
我这里摘录和粗略解释一下。
###########################
#
# (1) 初始化参数设置的建议
#
###########################
(1.1) sec_case_sensitive_loacgon
在12.1.0.1中不建议修改。默认值是true，但是如果设置成false，启动的时候会有提示：ORA-32004: obsolete or deprecated parameter(s) specified for RDBMS instance。但是设置成false仍然生效，即忽略大小写的密码可以登录。
(1.2) SQLNET.ALLOWED_LOGON_VERSION_SERVER
在12c中默认值是11，所以如10.2.0.5的JDBC连接过来，就会报错ora-28040，虽然可以设置SQLNET.ALLOWED_LOGON_VERSION_SERVER=8来解决这个问题，但是由于今后11.1以下版本的JDBC不再被oracle支持，因此还是建议升级JDBC驱动来实现。
jar file和JDBC驱动之间的关系，参考Doc ID 401934.1。 10.2版本的JDBC，使用ojdbc14.jar；11.2版本的JDBC，使用ojdbc6.jar；12.1.0的JDBC使用ojdbc7.jar。
SQLNET.ALLOWED_LOGON_VERSION_SERVER 的值有{ 8 | 10 | 11 | 12 | 12a }，各个值如下含义：
12a for Oracle Database 12c authentication protocols (strongest protection)
12 for the critical patch updates CPUOct2012 and later Oracle Database 11g ,authentication protocols (recommended)
11 for Oracle Database 11g authentication protocols (default)
10 for Oracle Database 10g authentication protocols
8 for Oracle9i authentication protocol
默认值是11，推荐值是12（如果你没有小于10.2.0.5的客户端）
(1.3) AUDIT_TRAIL
取值范围是: { none | os | db [, extended] | xml [, extended] }，默认值是db或者none。
和12c的新特性Unified Auditing有关。是否启用unified auditing，可以用select VALUE from V$OPTION where PARAMETER='Unified Auditing';检查。
Unified Auditing默认是工作在mixed模式。
建议：
如果你以前没有审计，那么你可以设置成none。
如果以前有审计，建议设置成db。
更多信息，参考 http://tinyurl.com/UnifiedAuditing
(1.4)DEFERRED_SEGMENT_CREATION
从11.2开始，这个值的默认值是true，建议12c中设置成false。
(1.5)JOB_QUEUE_PROCESSES
从11.1开始，这个值是1000，建议设置成和CPU core相等的值。
(1.6)_DATAFILE_WRITE_ERRORS_CRASH_INSTANCE
这个值默认值是true。所有datafile的IO写error，都会导致数据库crash。
在11.2.0.2之前这个值是false，即只是offline datafile（非system），而不crash instance。11.2.0.2之后，是true。
建议：注意这个从11.2.0.2之后的变化。
(1.7) MAX_STRING_SIZE
这是在12c中的新参数。默认值是standard。
这个参数用于控制varchar2，nvarchar2，raw类型的最大值。standard下，行为和12c之前一样，即varchar2和nvarchar2是4000 bytes，raw是2000 bytes，
改成extended之后，启用了32k strings新特性，varchar2、nvarchar2、raw最大长度可以达到32767 bytes。
修改方式：
1. startup upgrade
2. ALTER SYSTEM SET MAX_STRING_SIZE = EXTENDED;
3.运行@?/rdbms/admin/utl32k.sql
但是注意，单向修改，改了之后，就改不回来了。（可以flashback）
注意原生32k strings是以out-of-line的blob方式存储，且还是basic file，而如果是以modify成32k strings的是以in-line的方式行链接存储。
所以转32k strings需要考虑lob效率的问题。
###########################
#
# (2)其他在12c中的参数：
#
###########################
(2.1) _OPTIMIZER_AGGR_GROUPBY_ELIM
Values: { TRUE | FALSE } 默认值是true
Recommendation: FALSE - Wrong Results with GROUP BY Clause in Nested Query (Doc ID 19567916.8)
建议值：false
(2.2) INMEMORY_FORCE
Values: { DEFAULT | OFF } 默认值是default
Explanation: In-Memory Optimization
Recommendation: OFF – Unless you have an Oracle In-Memory license
建议值为off，除非你有in-memory的license
(2.3) OPTIMIZER_DYNAMIC_SAMPLING
如果统计信息不存在，进行动态采样的比例。
Values: { 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 } 默认值是2
解释:
a.0: Off
b.2: Check 不多于64个blocks - generate stats during parse
c.11:12c的新增加值，进行动态采样的block数由系统自动决定，采样结果会保留在statistics repository，供下次使用。
建议值：参考在线文档SQL Tuning Guide，最佳实践是在session级设置。
(2.4) AWR Lite Snapshots
参考Doc ID 1993045.1，建议在手工snapshot的时候，用lite模式
--默认值是bestfit
_AWR_SNAPSHOT_LEVEL = BASIC | LITE | TYPICAL | ALL | BESTFIT
--手工snapshot的时候，建议lite
SQL> exec dbms_workload_repository.create_snapshot('LITE');
(2.5) _OPTIMIZER_COST_BASED_TRANSFORMATION
默认值是on，从10.2开始，默认值就是on了，但是在11.2.0.3之前，建议设置off
(2.6) SESSION_CACHED_CURSORS
默认值是50，建议设置成200，然后按照208857.1进行调整。
太大容易有shared pool碎片
(2.7) _MEMORY_IMM_MODE_WITHOUT_AUTOSGA
默认值是true，如果需要禁用偷buffer cache的属性，设置成false
(2.8) OPTIMIZER_USE_PENDING_STATISTICS
默认值是false，可以在session级设置成true后，测试新的但是还没发布的统计信息，对sql的影响。
(2.9)OPTIMIZER_USE_INVISIBLE_INDEXES
是否让优化器看见invisible的索引，默认值是false
ALTER INDEX idx_ename ON emp(ename) INVISIBLE;
ALTER SESSION SET OPTIMIZER_USE_INVISIBLE_INDEXES=TRUE;
(2.10) 其他建议值：
a. _optimizer_adaptive_plans=FALSE （需要评估，Adaptive Query Optimization Doc ID 2031605.1）
b. _optimizer_unnest_scalar_sq=FALSE （Bug 19894622 - ORA-600 [kkqcsfixfro:1 -- frooutj] error occur in 12c (Doc ID 19894622.8)）
c. _rowsets_enabled=FALSE （Bug 22173980 : WRONG RESULTS WHEN "_ROWSETS_ENABLED" = TRUE）
d. _optimizer_reduce_groupby_key=FALSE （Bug 20634449 - Wrong results from OUTER JOIN with a bind variable and a GROUP BY clause in 12.1.0.2）
e. _kks_obsolete_dump_threshold=0 or 8（Huge Trace Files Created Containing "----- Cursor Obsoletion Dump sql_id=%s -----" (Doc ID 1955319.1) ，该参数取值范围是0～8，默认值是1。设置0表示永远不dump，设置8表示parent cursor obsoleted 8次之后才dump。）

# (3)Data Pump的一些参数：

(3.1)VIEWS_AS_TABLES 参数，可以将view导出成表。

(3.2.2)TRANSFORM=LOB_STORAGE:SECURE_FILE
这个参数的作用是，将basic file的lob，导入时转换成securefile。
在12c中，DB_SECUREFILE = { NEVER | PERMITTED | PREFERRED | ALWAYS | IGNORE }为这几个取值，在COMPATIBLE 为12.0.0.0以上的情况下，DB_SECUREFILE值为PREFERRED，即在默认情况下，创建的lob是security file。如果要basic file，那么需要手工指定。
注：DB_SECUREFILE值为PREFERRED，也是12c中的改变，在12c之前没有。

这个参数的作用是，在导入的时候，忽略原库中DDL中的storage的设置。类似用dbms_metadata.get_ddl获取DDL语句之前，执行EXEC DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'STORAGE',false);从而忽略storage参数。

COMPRESSION_ALGORITHM = [ BASIC | LOW | MEDIUM | HIGH ]，用于控制在导出时的，且启用压缩功能时，CPU的消耗。有如下4个值
a. BASIC 和原来一样
b. LOW 减少CPU使用率
c. MEDIUM 建议值，和basic类似，但是有不同的算法
d. HIGH: 使用更多的CPU用于压缩
