check your SNAPSHOT CONTROLFILE parameter with RMAN
replace parameter shared location  or ASM location.



[oracle@testdb01 oracle]$ rman 

RMAN> connect target /

RMAN> show SNAPSHOT CONTROLFILE NAME;

CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2.0.3/db_1/dbs/snapcf_testdb1.f'; # default

Linux dns TTL time control

[oracle@testdb01 ~]$   host -a testdb02


result sample of command:

;; QUESTION SECTION:
;testdb02 IN   A

;; ANSWER SECTION:
testdb02 492 IN A      192.168.3.24


492 is remaining time  of TTL.   if you try againg TTL is reduced

Debuging PL/SQL Procedure

Which privileges do you need?

grant debug any procedure to appuser;
grant debug connect session to appuser;

You must compile with debug option procedure before to run.

alter procedure my_proc compile debug;


http://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_9013.htm#i2062318

DEBUGGING:	—
DEBUG CONNECT SESSION	Connect the current session to a debugger.
DEBUG ANY PROCEDURE	Debug all PL/SQL and Java code in any database object. Display information on all SQL statements executed by the application. Note: Granting this privilege is equivalent to granting the DEBUG object privilege on all applicable objects in the database.

Interval partition

Interval partitioning is an extension to range partitioning.
You can use interval partition to automatically add new partitions.

Sample


CREATE TABLE mypart_table
(
  TARIH         DATE                            NOT NULL,
  KOD           NUMBER(5)                       NOT NULL,
  ALAN          VARCHAR2(600 BYTE),

)
PARTITION BY RANGE (TARIH)
(  
  PARTITION mypart_table_201303 VALUES LESS THAN (TO_DATE('2013-04-01', 'YYYY-MM-DD')),
  PARTITION mypart_table_201304 VALUES LESS THAN (TO_DATE('2013-05-01', 'YYYY-MM-DD')),
  PARTITION mypart_table_201305 VALUES LESS THAN (TO_DATE('2013-06-01', 'YYYY-MM-DD')),
  PARTITION mypart_table_201306 VALUES LESS THAN (TO_DATE('2013-07-01', 'YYYY-MM-DD'))
)
;


CREATE INDEX BANKDB.IDX_mypart_table_01 ON mypart_table
(TARIH, KOD)
LOCAL;


--add partition interval 1 day

alter table mypart_table set INTERVAL( NUMTODSINTERVAL(1,'DAY'));

You can't modify interval partitions. You can disable and enable again.

--disable interval 
ALTER TABLE mypart_table SET INTERVAL ();
