Ques:- I have two databases both are Oracle while loading datafrom source to target the job takes 30 min but I want toload less time how?

Asked In :- Educe Solutions, telstra, apptio,

Right Answer:
To reduce the loading time from source to target in Oracle databases, consider the following strategies:

1. **Use Bulk Loading**: Utilize SQL*Loader or Oracle Data Pump for bulk data loading.
2. **Optimize Network Performance**: Ensure a high-speed network connection between the databases.
3. **Increase Parallelism**: Use parallel processing to load data concurrently.
4. **Disable Indexes and Constraints**: Temporarily disable indexes and constraints during the load, then rebuild them afterward.
5. **Use Direct Path Load**: If applicable, use direct path loading to bypass certain database overhead.
6. **Tune Database Parameters**: Adjust memory and performance parameters for optimal loading.
7. **Partitioning**: If applicable, partition the target tables to improve load performance.
8. **Minimize Logging**: Use NOLOGGING mode for the target tables if data recovery is not a concern.

Implementing these strategies can significantly reduce the data loading time.

```plsql
:global.var1 := value1;
:global.var2 := value2;
OPEN_FORM('form_name.fmb');

Ques:- What is global tempory table?

Asked In :- textron aviation,

Right Answer:
A global temporary table (GTT) in Oracle is a table that stores data temporarily for the duration of a session or a transaction. The data is private to the session or transaction, meaning other sessions cannot see it. The structure of the table is permanent, but the data is deleted automatically when the session ends or the transaction is committed or rolled back, depending on how the GTT is defined.
