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 ();

Using JDBC with Firewalls

from Oracle® Database JDBC Developer's Guide and Reference

http://docs.oracle.com/cd/B19306_01/java.102/b14355/apxtblsh.htm#CHDBBDDA

Firewall timeout for idle-connections may sever a connection. This can cause JDBC applications to hang while waiting for a connection. You can perform one or more of the following actions to avoid connections from being severed due to firewall timeout:

• If you are using connection caching or connection pooling, then always set the inactivity timeout value on the connection cache to be shorter than the firewall idle timeout value.
• Pass oracle.net.READ_TIMEOUT as connection property to enable read timeout on socket. The timeout value is in milliseconds.
• For both JDBC OCI and JDBC Thin drivers, use net descriptor to connect to the database and specify the ENABLE=BROKEN parameter in the DESCRIPTIONclause in the connect descriptor. Also, set a lower value for tcp_keepalive_interval.
• Enable Oracle Net DCD by setting SQLNET.EXPIRE_TIME=1 in the sqlnet.ora file on the server-side.

Oracle Database fires multiple triggers in an unspecified, random order, if more than one trigger of the same type exists for a given statement; that is, triggers of the same type for the same statement are not guaranteed to fire in any specific order.

ERROR at line 1:

ORA-14265: data type or length of a table subpartitioning column may not be changed 

you have to drop/create table to achive this problem.

You can create non-partition table for each partition which has same name with partition

and exchange partition 

or

If have enoguh downtime you can export/import with orjinal table. 

or

you can create dummy table desired structure and you can insert/select/rename.
