Install the latest patch set, the one you mention But, I'd resume your post in something much-much easy. Dear Buddy, Good Doc Thanks Mahendran. Former Member Blog Post Author. Thanks Mahendran Hi, Thanks for the document. Regards Githen. Hi Manas, Thanks for sharing nice document. Mohomad Swalay. Hi Manas, Can i follow the same procedure for upgrading Oracle Regards Swalay.
Also run dupgdiag. This is caused when required aggregate columns are missing in the plan in the projection list of operations. Direct read issues: There are reports of excessive direct reads after a migration to 11g r2.
See my Adaptive path read operation tips Issue the following statement to workaround the direct read issue. Resource Manager enables itself: The Oracle 11g resource manager now turns-on by default. See MOSC note See this important AMM bug and the associated fix.
Optimizer enhancements: Oracle says that the lack of extended statistics is the 1 cause of poor plans in 11g. With each release of Oracle we see improvements to the SQL optimizer, and you can expect to see many plan improve, but some which may get worse. Oracle introduced a new support model offering extended support only to certain releases.
Oracle Database Long Term Releases are ideal for use cases that benefit from less frequent upgrades to newer releases. Long Term Releases offer the highest level of stability and the longest length of error correction support.
These releases have 5 years of Premier Support, followed by 3 years of Extended Support. Innovation Releases are designed to enable customers to continuously use leading-edge technologies to rapidly develop or deploy new applications or augment existing applications.
Production workloads can be deployed on Innovation Releases if upgrading within 2 years to a newer release is factored into the deployment plan. To help you plan, below is a visual roadmap that captures Oracle Database Releases from Note, not all releases are eligible for Extended Support or error correction options i. It is OK to skip versions. Oracle ACS will provide code fixes or workarounds to correct newly discovered issues that result in Severity 1 production incidents, continue to evaluate security-related risks and other newly discovered vulnerabilities that could potentially impact 11gR2 and thereby provide critical security patches or updates for 11gR2, provide the customer with one Upgrade Planning Workshop designed to assist with developing an upgrade plan during the contract period.
This support offering is limited to Oracle Database The service also excludes any updates related to cryptography and network encryption. But instead of focusing on the 11g, 12c, and 18c de-support issues as the primary driver of the 19c upgrade, let's look at some of the reasons why it makes sense to upgrade to 19c sooner rather than later.
Reason 1 — Automatic Indexing: One of the most compelling features that came in Oracle Database 19c is automatic indexing, which is based on common SQL tuning methods. The difference is that the process will be fully automated instead of being manual.
Oracle Database 19c will identify candidate indexes, verify their effectiveness, perform online validations, and then implement the indexes where appropriate.
Reason 2 — Automated Testing of Query Plans: With Oracle Database 19c, database administrators DBAs will no longer need to manually perform regression tests on new query execution plans prior to upgrading from earlier versions of the database management system. New functionality built into 19c will automatically check the built-in execution plans against existing ones, and then replace the current plans that can benefit from upgrading and retaining those that will be faster without the upgrade.
This means queries run as well as or better than before without DBAs having to take any action. This new feature will make it possible to run DML statements against an active-standby database. Data Guard will redirect the statements to the primary database, where the data changes will be applied.
The updated data will then be streamed back to the standby database to maintain redundancy. The Easy Connect syntax was simplified in Oracle 19c. It can now include multiple hosts and ports in connection strings designed to make it easier to load-balance client connections. The Easy Connect adapter can also accept a list of name-value pairs. Reason 5 — Previously chargeable features now offered free of charge: Oracle now allows limited use of Multitenant, In-Memory and full use of Spatial at no cost to you.
You also get to use up to 16 GB of in-memory column store cache architecture without having to purchase In-Memory option. There are several options available to upgrade databases from their current version to Oracle Database 19c.
The methodology customers choose is driven by their specific requirements and use cases.
