Tuples in Python

 Tuples

Basically Tuples in Python are very similar to Lists, but, Tuples are immutable which means that they can not be modified/changed. We generally use Tuples to make sure the values are not changed like, dates, Year, and days of the week or dates on a Calendar. 


Creating a Tuple:

>>> my_t1=(1,2,3)
>>> my_t2=('one','two','three')
>>> my_t1
(1, 2, 3)
>>> my_t2
('one', 'two', 'three')


-- check the length of tupple:
>>> len(my_t1)
3
>>> len(my_t2)
3

-- Tuples can have mixed objects as like Lists.

>>> my_t3=(1,'two',3,'four')
>>> my_t3
(1, 'two', 3, 'four')

-- indexing with tuples 

>>> my_t3=(1,'two',3,'four')
>>> my_t3[2]
3

Immutable Tuples

We can not modify the value. Here is the example:

>>> my_t3=(1,'two',3,'four')
>>> my_t3[2]=4
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'tuple' object does not support item assignment


-- can not append/add too

>>> my_t3=(1,'two',3,'four')
>>> my_t3.append('five')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'tuple' object has no attribute 'append'

Auditing in Oracle database

Unified Auditing: Oracle Database 12c Release 1 introduces a new auditing feature called Unified Auditing (12.1). Oracle Unified Auditing modifies the database's fundamental auditing capabilities. In earlier versions of Oracle, each component has its own audit trail. With unified auditing, all auditing is compiled into a single repository and view. Due to the fact that all audit data is now in a single location and a single format, there is a double simplification as a result. This data is made available in a consistent format in the UNIFIED AUDIT TRAIL data dictionary view, which is made possible by the unified audit trail, which is stored in a read-only table in the AUDSYS schema in the SYSAUX tablespace.  DBAs can build audit rules and then assign them to various users using Oracle 12c Unified Auditing, which has the same advantages as giving users varying system capabilities based on their responsibilities. The unified_audit_trail database will contain all of the audit records....

rs.stepDown() in MongoDB replication

It instructs the primary of the replica set to become a secondary. After the primary steps down,the eligible secondaries will hold an election for primary. Generally, the rs.stepDown() does not immediately step down the primary. If no electable secondaries are up to date with the primary, the primary waits up to secondaryCatchUpPeriodSecs (by default 10 seconds)  for a secondary to catch up. Once an electable secondary is available, the method steps down the priamry.  Once stepped down, the original primary becomes a secondary and is ineligible from becoming primary again for the remainder of time specified by stepDownSecs. The rs.stepDown() method attempts to terminate long-running user's operations that block the primary from stepping down, such as an index build, a write operation, or a map-reduce job. Syntax: rs.stepDown(stepDownSecs, secondaryCatchUpPeriodSecs)
