A virtual network appliance in a regional subnet is an API gateway in the OCI. Back-end services such as public, private, and partner HTTP APIs and Oracle Functions get through an API gateway.
Standard package refers to a set of Tariffs that contains, among other things, rental, call charges, data transport charges, free calls, free data allowances, deposits, and additional charges as decided by the Department for specific Public Telecommunication Services from time to time.
No, Oracle Database is included in all packages, including the regular, enterprise, high-performance, and extreme performance packages. Encryption of Transparent Data
. The following are the various Oracle form modules:
Oracle can use the ANALYZE command to conduct various tasks on an index, table, or cluster. The following is a list of Oracle commands that use the ANALYZE command:
For database recovery in Oracle, we will use a control file. When an ORACLE database starts, the control file helps identify the database and redo log files that must open for database operations to proceed.
A binary string of changing length is known as a BLOB data type. Two gigabytes of memory get stored in it—the length refers to bytes for the BLOB data type.
A logical backup is a method of reading and writing a collection of database records into a file. The backup gets created using an Export tool, and the recovery performs using an Import program.
Recursive hint refers to the number of times a dictionary table is called again by various processes. Due to the short capacity of the data dictionary cache, a recursive hint occurs.
Oracle reports empower businesses by securely sharing information at any level within or outside the organization. The Oracle report uses REP and RDF file extensions.
Hash clustering is a technique for storing data in hash tables and improving data retrieval performance. The hash function is applied to the cluster key value of each table row and stored in a hash cluster.
Security Assessment, User Assessment, Data Discovery, Data Masking, Scalability and Performance, Availability, Backup and Recovery, Security and Activity Auditing are the features in Oracle OCi.
A tablespace is the logical storage unit of an Oracle database. Tablespace groups link the database's logical structures together. The data is logically stored in Oracle tablespaces and physically saved in the data files associated with the respective tablespaces.
A SYSTEM tablespace forms automatically when any database gets created in the Oracle database system. In the SYSTEM tablespace, you'll find all of the database's data dictionary tables. Because the SYSTEM tablespace includes the data dictionary that Oracle requires, it must remain up at all times.
Oracle uses snapshots, also known as materialized views, to duplicate data to non-master sites in a synchronized environment. In a data warehouse context, snapshots are utilized to cache "expensive" searches. In other words, a snapshot is a replica of the target master table taken at a specific point in time.
Savepoints can break up a significant transaction into smaller chunks. It enables the reversal of a transaction. There are a total of five save points available. It's where we keep our data, and if something goes wrong, you can roll back to the point where you saved your SAVEPOINT.
In the Oracle shared pool, there are two memory layers:-
Hash clustering is a technique for storing data in hash tables and improving data retrieval performance. The hash function is applied to the cluster key value of each table row and stored in a hash cluster.
Below are the different types of database objects:
This section contains questions of OCI for experienced candidates who want to crack the interview.
Save Points are a way to break down a transaction into smaller chunks. It allows you to undo a portion of a transaction. Oracle Database provides for a maximum of 5 save points. It is possible to roll back from the point where the SAVEPOINT holds whenever an error occurs.
The post-database commit triggers after Oracle forms issue a commit to a completed transaction, whereas the post-form commit triggers fires during the post and commit transactions process after the database commit.
To delete the compartment in OCI, select Identity & Security from the navigation menu. Select Compartments from the Identity menu. The compartments in your tenancy are listed. To delete a compartment, go to the Actions menu and select Delete Compartment.
Dynamic Routing Gateways (DRGs) are routing gateway that allows you to change your route. A DRG serves as a virtual router, connecting your on-premises networks to VCNs and routing traffic between VCNs. A routing table connects with each DRG attachment and routes packets entering the DRG to the next hop.
Oracle Data Masking and Subsetting Pack is a flexible solution for masking and subsetting sensitive production data shared across non-production settings.
Unlock the value of data while reducing risk and storage costs. Oracle Data Masking and Subsetting enables safe and cost-effective data supply in various scenarios, including test, development, and partner environments.
Oracle Audit Vault and Database Firewall analyze Oracle and non-Oracle database traffic to detect and block risks and combine audit data from databases, operating systems, directories, and other sources to improve compliance reporting.
Wallet owners use Oracle Wallet Manager to manage and modify the security credentials in their Oracle wallets.
The Oracle Cloud Infrastructure Resource Manager (OCI Resource Manager) is an Oracle-managed service that automates the deployment and operation of all Oracle Cloud Infrastructure resources.
A unique ID called Oracle Cloud Identifier assigns to most Oracle Cloud Infrastructure (OCI) resources (OCID). Each resource in a tenancy gets an individual ID.
The Oracle database's BLOB data type is a binary string of changeable length. It is used to store two gigabytes of memory and requires a length specification in bytes. The following is an example for using the BLOB data type:
Creating a Table:
Querying For All Logotype Pictures:
Data Safe is an Oracle Cloud Infrastructure's Next Generation Security (OCI). Each customer's data is kept in its database to ensure privacy: data Safe data and all access to client databases audits.
A tenancy can contain hundreds of compartments, and compartments are accessible. Your design's only significant limitation is that you can only create six tiers of nested compartments.
Oracle offers a dependable and scalable cloud object storage solution. According to the Oracle website, this is an 8000 TB storage used to store and access data in ever-growing databases. This is the location where Oracle database backup data saves.
Oracle database cloud service is identical to a single-instance Oracle database, except that the database host in the cloud, and Oracle provides all computational resources, such as storage and electricity.
Oracle Database is a well-known relational database corporation that has been around for a long time. Oracle Cloud offers a database as a Service. Oracle databases, which support enterprise databases, is a cloud service that can help databases used for testing, development, and live production databases. Oracle Cloud provides high availability and scalability options, business continuity, time savings, and various other benefits. To make things easy, choose a cloud service from a database business.
