NEW QUESTION # 86
Which index type is designed to index catalog information?
- A. CONTAINS
- B. CTXCAT
- C. CTXRULE
- D. CONTEXT
Answer: B
Explanation:
CTXCAT is an index type that is designed to index catalog information such as product names, prices, descriptions, etc. CTXCAT indexes are suitable for e-commerce applications where users can query on multiple attributes of a product8. CTXCAT indexes are faster to create and maintain than CONTEXT indexes, which are designed to index large amounts of text such as documents, web pages, etc. CTXCAT indexes also support mixed queries that combine structured and unstructured predicates9. CTXRULE is an index type that is designed to index a set of queries or rules that can be evaluated against documents or rows in a table10. CONTAINS is not an index type, but a SQL operator that performs text searches on CONTEXT and CTXRULE indexes11. Reference:
Oracle Text Indexing Elements - Oracle Help Center, section "CTXCAT Index Type".
Oracle Text Application Developer's Guide - Oracle Help Center, section "Choosing an Index Type", subsection "When to Use a CTXCAT Index".

CONTAINS - Oracle Help Center.
NEW QUESTION # 87
Your customer has upgraded their on premise 11.2 database to 12.2. During this migration the database was migrated to a pluggable database and is now in production.
How should the customer unplug their database to migrate to Autonomous Database (ADB)?
- A. Create a database link from source database to the ADB environment and clone the PDB.
- B. Pluggable databases cannot be migrated to ADB using plug, unplug or clone.
- C. Unplug to an xml file so database files and xml file can be uploaded to object storage.
- D. Unplug into a pdb archive which can be uploaded to object storage.
Answer: B
Explanation:
Since an ADB database has some restrictions on the object types and Oracle Database Options you need to use a logical migration method rather than a physical one.
The main migration tool for migrating to ADB is Data Pump. You can export your schemas and import them into ADB using Data Pump. To sync up the additional/incremental changes on the source database during the export/import process you can use GoldenGate or GoldenGate Cloud Service to replicate those changes to ADB.
In the current release you cannot use physical migration methods like backup/restore, Data Guard, Pluggable/Unplug , database clones, and transportable tablespaces to move your existing database to ADB.
