You should be good by using the defaults for optimizer_adaptive_statistics=FALSE and optimizer_adaptive_plans=TRUE. WebLogic | Blog | OPTIMIZER_ADAPTIVE_PLANS and OPTIMIZER_ADAPTIVE_STATISTICS will take all functions on this one, exactly to better separate things and avoid changing “more than needed”. In OLTP environments, where SQL runtime is typically smaller, the additional optimization time may become a significant part of the elapsed time, for little extra benefit. If value is TRUE, then database link name should be same as that of the database it is pointing. 21c | 2. 8i | I don't want to set optimizer_features_enable to 10.1.0 at the system level so if the hidden parameter doesn't really work, then I'll have to install patchset 10.2.0.3 instead.

This change in the control of the adaptive optimizations has been back-ported to 12.1. Q: Does adaptive distribution for parallel processing work as expected on a Virtual server where resources can be spread over several other servers? Document remote OS authentication in the System Security Plan. About, About Tim Hall There are two answers: The system is an unpatched 12.2 system: A: Yes, set optimizer_adaptive_reporting_only = true. This is the third and final post on follow up questions from the Redgate webinar I did on 12c Adaptive Optimization (the link goes to a recording of the webcast by the way).. Also, here are links to the 2 earlier posts: 12c Adaptive Optimization – Part 1. When I alter my script it works fine: alter session set "_ORACLE_SCRIPT"=true; TESTER IDENTIFIED BY TESTER; But I don't want to add this to every script.

Is there a way you can persist this setting in the database? The recommended Oracle 12.2.0.1 optimizer_features_enable parameter and the compatible parameter (if set) need to be reset to their default values. And, in case it is set to FALSE, all the features are (obviously) disabled. OPTIMIZER_ADAPTIVE_STATISTICS is false so by default you will not have the following 12c features: SQL Plan Directives, Statistics feedback, Performance feedback, Adaptive dynamic sampling for parallel query. We want to change only optimizer_adaptive_plans to FALSE, Can you please tell me is there a dependency on optimizer_adaptive_statistics, will there be any impact at application level. Connor … Although the features are discussed in separate articles, you really need to consider them in combination as there is a lot of interaction between the separate features. SQL> alter system set sec_case_sensitive_logon=false scope=spfile; System … If it’s set to TRUE (the default), the feature is enabled. Give it a test and let us know what you find out. It achieves our goal as it even disables the creation of SPD, but it also disables Adaptive Plan, which is a very nice feature. Also see my bind_aware hint tips. The reasoning for this is many of these optimizations are more appropriate for data warehousing, where there optimization time is is a small proportion of the query runtime.

Also in this doc they need to alter the session. OPTIMIZER_ADAPTIVE_PLANS: Default (TRUE). You can read about it here. RAC | No. alter system set optimizer_adaptive_features=false scope=both; we can set this hidden parameter: alter system set "_optimizer_dsdir_usage_control"=0 scope=both; Dynamic Sampling is also caused performance issue, So, we can also disable with following parameter or you follow link for more detail: Dynamic Sampling alter system set … In Oracle 12.2 the OPTIMIZER_ADAPTIVE_FEATURES parameter has been removed and replace by two new parameters. OPTIMIZER_ADAPTIVE_FEATURES enables or disables all of the adaptive optimizer features, including adaptive plan (adaptive join methods and bitmap pruning), automatic re-optimization, SQL plan directives, and adaptive distribution methods. OPTIMIZER_ADAPTIVE_FEATURES enables or disables all of the adaptive optimizer features, including adaptive plan (adaptive join methods and bitmap plans), automatic re-optimization, SQL plan directives, and adaptive distribution methods. By switching the SEC_CASE_SENSITIVE_LOGON initialization parameter to FALSE we are able to connect using both variations of the password. Videos | In addition to that, only OPTIMIZER_ADAPTIVE_PLANS is set to true by default. Both parameters are modifiable at both the session and system level. Basic. This article provides links to articles on the individual features of Adaptive Query Optimization. Misc | 1. Run the ALTER SYSTEM to set the DBFIPS_140 parameter..

The init.ora/spfile parameter SEC_CASE_SENSITIVE_LOGON got deprecated since Oracle Database 12.1.0.1.This means, we don’t do any further developments to it, you shouldn’t change it from its default TRUE – and if you still do you’ll receive a nice warning during STARTUP of your database:. OPTIMIZER_ADAPTIVE_PLANS controls adaptive plans. In 12.2 version, this parameter optimizer_adaptive_features was obsoleted and replaced with two parameters : ‘optimizer_adaptive_plans’ and ‘optimizer_adaptive_statistics’. Disable O7_dictionary_accessibility to restrict access to system tables to users granted privileges to access objects owned by all users. 18c | Misc | 2. 9i | select /*+ OPT_PARAM('_optimizer_adaptive_plans','true') */ customer_name from customer; See my notes on adaptive execution plans and 12c adaptive SQL optimization. Setting optimizer_adaptive_statistics to FALSE does not disable the creation of SQL plan directives. alter system set optimizer_adaptive_plans=FALSE scope=spfile; alter system set optimizer_adaptive_statistics=FALSE scope=spfile; alter system set optimizer_features_enable='12.1.0.2'scope=both; The last parameter will take effect immediately ( scope=both ) but the first two will require a database restart to go into effect. SOLUTION: First, we need to check whether the parameter is system modifiable or not. SQL> alter system set cluster_database=false; alter system set cluster_database=false * ERROR at line 1: ORA-02095: specified initialization parameter cannot be modified If Using spfile use the below command : SQL> alter system set cluster_database=false scope=spfile; Note that by default the parameter is set to TRUE and, therefore, all the mentioned features are enabled.

I’d recommend to test and keep an eye on it but … Some of the features are renamed versions of functionality from previous releases, while others are new to Oracle Database 12c. 19c | To disable the result cache, you must explicitly set result_cache_max_size = 0. Instead, it prevents them from being used in conjunction with dynamic statistics to influence SQL execution plans. Parameter settings with scope=both will take effect immediately. Articles | ... SQL> alter system set global_names=TRUE scope=both; System altered. set optimizer_adaptive_features=false This disables all adaptive features of the optimizer and that’s probably too wide. Since, in 12c optimizer_adaptive_features is deprecated and has been divided into 1. optimizer_adaptive_plans= True and 2. optimizer_adaptive_statistics= FALSE. For example, the startup time of the Fabasoft Folio Backendservices in a test environment increased from 90 seconds to about 1 hour. Oracle introduced a new feature
