- Uses SQL language, which is great and well known for most people
- Great performance to deal with lots of data
- Good and vast documentation and community
- Compared to the most modern databases, it is hard to learn
- Could be more elastic
- Expensive licenses
little knowledge of databases can use the SQL language to deal with the
tables and contents. BUT it is expensive, so if you have a small business, it may not be the best option.
- Oracle12c Data Guard ensures high availability, data protection, and disaster recovery for enterprise data. It is one of the oracle finest solution for disaster recovery and data corruption. In this setup - You have one Primary and one or more standby DB in two or more different geographical locations. So, if the database hosted in one location goes down due to planned or unplanned outages, you can easily operate business from remote location database.
- Oracle12c RAC provides Scale-up architecture. Oracle RAC ensures High Availability. In RAC architecture you have at least two or more physical servers with same configuration connected thru interconnect network. So, if one server goes down, you still have database running from the other(surviving) nodes. In this architecture - You can have appropriate on-demand services. You can easily scale up Servers, CPU, Memory.
- Oracle12c has amazing Performance Tuning framework. You can very easily fine-tune databases running on Oracle12c. Some of the great features are Oracle ADDM, AWR report, ASH report, SQL report, SQL Plan Management, Tuning Advisor - SQL Tuning Advisor, SQL Access Advisor.
- Oracle12c has great Back and Recovery solution using Oracle RMAN(Recovery Manager). Without much intervention and work, you can easily restore the database backup whenever and whereever you want.
- Oracle12c provides great security standards that meet fundamental data security requirements - Data Confidentiality, Data Integrity and Data Availability.
- Oracle Label Security, Oracle Data Redaction, Oracle Data Masking and subsetting, Transparent data protection, database storage encryption, Unified Auditing, and Oracle fine-grained audit are some great oracle features.
- In Oracle Data Guard - Oracle standby database is most of the time passive and nothing happening on it other than applying the log. Even in Oracle Active Data Guard configuration - You can not do more than running the business SQL query on the standby. Oracle must come up with solution such that standby database can also be fully utilized as a full operational database.
- Oracle should improve on Oracle internal locking mechanism, latch, and data concurrency. I have seen databases which runs fine with less number of ACTIVE user sessions. When ACTIVE user sessions are increased in the same database - db performance is deteriorated proportionately. If the database kernel has designed correctly, there won't be any db performance issue regardless of any number of user connections/sessions.
- In current time - DB growth is very common, today your db size is 20GB, It may be 500GB at the end of the year, so on and so on. With respect to db size increase, Oracle must improve on RMAN(Recovery Manager) backup tool. The expectation is that faster backup and restore as and when needed. There is always a debate that - Please don't run RMAN backup,data pump export backup, and gather stats job during business peak hours as it will impact DB performance. Oracle database should have designed in such that Administrative jobs like Backup, data pump export and DB gather stats should not have db performance impact anytime, at any cost. Even Oracle claims that Oracle DBRM (Database Resource Manager) is solution to this problem, but, in actual, it doesn't address the problem in much better way.
Scenarios where Oracle12c DB is well suited:
1. Oracle12c DB with ODA(Oracle Database Appliance) is well suited for small to medium OLTP shops, where you don't have much DB workload. Oracle12c with ODA provides DB high availability, High redundancy, and good DB performance.
2. Oracle12c DB in EXADATA with IORM implementation is well suited for mixed DB environment. Mix DB environment is the one in which some databases are development DB, some are Test DB, Some are QA DB, Some are OLTP, and Some are Data Warehouse DB.
3. Oracle12c is well suited for Banking, Financial, Retail, and Aviation Industry.
Scenarios where Oracle12c DB is less appropriate:
1. Oracle12c is less appropriate for small shops like Restaurant business, Hotel/Motel Business, Burger Shop and Coffee House.
2. Oracle12c is less appropriate for Research and Scientific work, Data Analysis, Big data Analytics. The data computational speed is not so good in Oracle world.
3. Oracle12c is less appropriate for Data Messaging industry.
2. Oracle has zoom call and chat session option linked to Oracle SR. Whenever you are in Oracle portal - you can chat with the Oracle Analyst who is working on your case. You can request for Oracle zoom call thru which you can share the your problem server screen in no time. This is very nice as it saves lot of time and energy in case you have to follow up with oracle support for your case.
3.Oracle has excellent knowledge base in which all the customer databases critical problems and their solutions are well documented. It is very easy to follow without consulting to support team at first.
- Automated database objects validation: correctness of views, packages, triggers, and everything is built-in. This minimizes the risk of using malfunctioned software and makes it easy to fix broken code.
- Rich programmability model: the database supports not only the very rich SQL but also PLSQL, Java and it has very good command-line tools that make change management easy and efficient.
- Excellent for data warehousing with its support for automatic materialized views management, table sequences, data types, updatable cursors, advanced SQL as Windowing Functions, built-in upsert semantics via the Merge SQL.
- The memory demand and management makes it impossible to run it in a container.
- It is hard to perform local unit testing with Oracle even using the personal edition (aggressive all the available memory grab for itself).
- Lack of built in database migrations (e.g. as Flyway).
- The need to install the Oracle client in addition to its drivers.
- The cost of running it, especially in the Cloud.
- Comes with very spartan community grade client/management tools whereas the commercial offerings tend to demand a premium price.
- Oracle Database 12c has the ability to scale to support intensive workloads.
- PL/SQL provides an efficient way to develop data-intensive processes that are able to interact with data without transferring it to an app server
- Partitioning, Compression and Encryption are some of the optional features that enhance performance, reduce costs and secure the information stored in Oracle Database 12c
- New (actually it is more than five years old) multi-tenant architecture is not as straightforward as SQL Server, but it has been enhanced in Oracle 12c Release 2 and later 18c and 19c.

- Regular updates & bug fixes
- Cost to manage various data
- Not preferable to use for small organizations
- Oracle's High Availability setup is very durable
- Performance of the database is very good for large databases
- DR setup is very reliable and can be setup easily
- ASM Storage management makes life easy in managing the datafiles
- Licensing cost is very expensive
- Sometimes getting an expert in Oracle support might be a challenge
The main business problems it addresses are database conversation, backups and the best part is that it supports multiple programming languages as well. We can save huge amount of data without any instability.
- Best thing about it is that it supports PL/SQL which is helpful in writing complex quarries easily.
- Its storage capacity , backup and recovery features make it the best database storage tool available.
- Other thing I like about this software is its interface is so good.
- Nothing much I could think of but ya it is very tough to understand it's functions and it's use.
- It is quite expensive as well.
- Stable database platform.
- Sellable enterprise database platform.
- Known and trusted vendor.
- Cost: platform is expensive
- Virtualization support: Licensing model makes virtualization costly.
- Difficult to work with: Oracle is one of the most difficult vendors to work with.
- Oracle is independent and portable platform.
- Easy to maintain backup and recovery for future use.
- Version change update and backward compatibility.
- Multiple databases can be supported at a time.
- Security and advanced user and roles management.
- Complexity of its usage for non-technical users.
- License cost is high.
- Recursive processing consumes a lot of resources and impacts performance.
- Can manage large databases and can support multiple databases simultaneously.
- Support programming concepts for implementing business logic.
- Multi user support with advanced security.
- Multitenant architecture has reduced the DB foot print and maintenance.
- Refreshing test database from production has become affordable and manageable.
- Restoring and recovering tables with Rman has become easy with 12c.
- Like MySQL Oracle also should provide a way to manage both unstructured and structured Data in same DB.
- More free training through OTN (self study videos) about 12c performance and how to adapt to it.
- Plan stability without adapting to use SPM when upgrading to newer versions. SPM has caused problems like taking up too much memory in the DB server when implementing it to overcome the shortcomings of upgrade with optimizer behavior altering the performance. In a way a more adaptable approach would be beneficial for DBAs for upgrade not compromising performance which I think is one of the biggest challenges upgrading .
Also running datapatch post-patching on a busy DB server is a nightmare as sometimes it would never complete and also unplugging and plugging DBs across clusters with different patch sets is a pain too.
- High stability and reliability
- A complete set of database features
- Performance is sub-optimal when data size is large.
- Non-trivial effort to setup. We have to build some automation so developers can save some time to set it up on their local machines.
- Backup and recovery
- Easy to integrate with other platforms
- Increased cost
- Require sophisticated hardware and software
- Pluggable databases really help with consolidation.
- Restore a table or table partition easily using RMAN.
- Online migration of a Table Partition or Sub Partition.
- License on virtual infrastructure.
- Technical support needs to improve.
- Data Guard setup needs to simplify and troubleshooting is still too complex.
Oracle user groups are a great place to discuss new trends, features, best practices, and challenges...etc. It is a great way to learn and a very positive influence on the user's community.
- Oracle Database does security and compliance very well out of the box without the need for much configuration.
- It works very well across on-prem and cloud deployments where we want part of the database in-house (due to compliance reasons) while the rest can be in the public cloud.
- Pricing can be improved to make it much more competitive with other RDBMS options in the space
- Best practices documents and deployment scenarios for running Oracle Database on non-Oracle cloud platforms would be helpful (for example Oracle Database on Google Cloud and Microsoft Azure).
- Certainly room for better integrated and automated SQL tuning.
- Highly performant/reliable and good technical support
- ACID -- Supports ACID transactions
- Non-structured Data -- XML, hard to use
- High Availability -- Real application clusters are available but it is difficult to set up and maintain
Using XML/non-structured data is not easy and I have noticed performance issues when the XML becomes deeply nested.
- "THE" Database, period. No more robust, secure, and stable relational database exists.
- Support from a wide range of professionals all over the world. Their academies and documentation is well above the average.
- Absolute best reliability in the market: ACID was kinda invented by those guys.
- Thousands of supporting tools, technologies, etc.
- They moved into the cloud! and are now a quite strong competitor vs. Amazon Web Cloud.
- The licences around using the DB are quite pricey. But hey, for a high quality, you cannot expect a freeware software...
- Replication using GoldenGate. We replicate almost 500k transactions per day between Brasil and México and it works perfectly.
- Velocity, quality, and support.
- Relational database to handle financial transaction systems using OLTP when customers pay for fuel.
- Parallel execution to apply multiple CPU and I/O resources to the execution of a single database operation.
- It's hard to find Oracle specialists.
- Oracle specialists are expensive.
- The database itself rarely goes down.
- Bringing up new Oracle instances is relatively painless.
- With the help of data pumps, moving data from place to place is a breeze.
- If you pay for their support, while they aren't the speediest, they are incredibly well informed and are an amazing help.
- Immensely complicated. Of all the databases we use, this one has by far the most moving parts.
- It is highly recommended to have a dedicated Oracle DBA on staff if you want your databases healthy. We have no such difficulty with Sybase, SQL Server or SAP IQ.
- While the Support Team is incredibly informative, they are often very slow to respond and are often unwilling to answer questions that don't directly solve the problem at hand.
I am also a member of Oracle's native user group. However, I find it far more effective to open a support ticket, so this is the direction I tend to lean.
- I believe other users have reviewed the pros already. I am addressing only the Cons of 12c R2.
- SYSAUX tablespace grows rapidly. I didn't need to add space to SYSAUX last a few years in 11g. But after upgrading to 12c R2 188.8.131.52, SYSAUX grows daily, and I have to add space to SYSAUX regularly, about every 2 weeks. I am currently opening an Oracle SR and working with Oracle Support on this issue.
- Some of our small databases only use about 5GB excluding SYSAUX. But SYSAUX uses 5GB alone!
- Almost all universities (if not all) in the USA have been using Banner application. But Banner app users fail to log on 12c Release 2 databases after upgrading to 12c R2 from 11g because of an Oracle Bug related to password-protected profile. I applied an interim bug to work around this issue. However, since Oct 2018, the PSU patching will not work. I must rollback the interim bug, and then patch the PSU, and then apply the interim patch again to resolve the Oracle bug. I asked Oracle to include the interim in the PSU in Oct 2018. But up to PSU Jul 2019, Oracle didn't implement it yet!
- First of all DB needs to be upgraded to Oracle 12c for support prospective from Oracle.
- Oracle 12 has some great features with respect to auditing.
- Keeping the data with respect to hot and cold rows is also a great features helping in managing data well.
- It had installation issues where it needed to have a patch applied before installation could begin. Downloaded software should have been tested before providing it to the user.
- Oracle 12.1 was not very stable so we had to migrate it to 12.2 after some time.
Oracle EBS OUG
- Performance - We have several ERP systems all running on various platforms. By far the best performance in terms of consistency being up and available is our Oracle platform. To put into scale, out of all three platforms, since I have been employed, Oracle has not been down once, while the other two have been down multiple times, to the point that my attendance at OOW2019 is focused on migration from other platforms to Oracle.
- Security - The matter of security is huge. One of the biggest points in choosing an Oracle database and appliance over anything else is the security it provides in counter to anything else on the market.
- Training - While there is an enormous amount of training available, there are still gaps in terms of availability for classroom-style learning. I have found it more effective to be in a classroom setting where one is held accountable at that moment in time as opposed to self-paced (pure personal preference).
- Cost - While we love the databases and appliances, the cost of maintaining is becoming an issue when competitors are coming in at such a lower point. Pushing this to a more profits oriented C-level makes justification difficult at times.
I get large value from being able to bounce thoughts and ideas from others who have gone through or encountered an issue that I may be dealing with. Also, getting feedback on how others have dealt with the cost issues when it comes to presenting to an executive team is great.
- An automated case management system has eliminated our duplication of effort in most instances.
- Having electronic work papers has allowed us to access other case files so we have access to more data saving us time and stopping the need for duplicate request.
- Our compliance cases are very task-oriented and the out of the box flow works very well with these cases.
- From the audit perspective, we have had to customize a lot to meet our electronic work paper needs.
- We have quite a few open Oracle service requests that have been outstanding for years.
- The history around the completed task is lacking out of the box.
