9. To reclaim the space in sysaux tablespace, we need reorg OPT tables.

13 rows selected.

10. To reclaim the space in sysaux tablespace, we need reorg OPT Index.

Listener Tracing

To find the issues with the listener connections you may not get complete info in listener log, you need to trace the the listener to monitor the connections, below steps will show you how to enable and disable trace.

statistics lock in oracle


To lock statistics for a tables:

exec dbms_stats.lock_table_stats('<schema_name>', '<tablename>');

Ex:

exec dbms_stats.lock_table_stats('scott', 'test');


when stats is locked the value of stattype_locked is ALL in dba_tab_statistics;

select owner, table_name, stattype_locked from dba_tab_statistics where stattype_locked is not null; 

To unlock table stats:

exec dbms_stats.unlock_table_stats('table_owner','table_name');

ex:

exec dbms_stats.unlock_table_stats('scott', 'test')

To lock statistics for a schema:

exec dbms_stats.lock_schema_stats('schema_owner'); 
exec dbms_stats.unlock_schema_stats('schema_owner');

MANAGER     RUNNING

example for goldengate unidirectional replication through Datapump process

Steps for performing an Online change Synchronization through Datapump process
====================================================

Make sure to create a same table structure on SRC and TRGT and manager process must be running .

Sample Table structure:
===============
Create table sender.empl (empid number(10),empname varchar2(10),constraint emp_key primary key(empid));

Create table receiver.empl (empid number(10),empname varchar2(10),constraint emp_key primary key(empid));

Prerequisite:
========
 In SRC:

Create a directories  “ mkdir /u01/app/oracle/GG/dirdat/etrail/“

In TRGT:
                              “ mkdir /u01/app/oracle/GG/dirdat/ptrail/“  for trail file’s location.


 On SRC

  1. GGSCI> add extract extdml, tranlog, Begin now

  1. GGSCI> add exttrail /u01/app/oracle/GG/dirdat/etrail/et,extract extdml

     3.  GGSCI> add extract dpump, EXTTRAILSOURCE /u01/app/oracle/GG/dirdat/etrail/et

    4.   GGSCI> edit params extdml

                 extract extdml
                 userid gguser@SRC,password oracle
                 exttrail /u01/app/oracle/GG/dirdat/etrail/et
                 table sender.empl;

5.  GGSCI> add rmttrail /u01/app/oracle/GG/dirdat/ptrail/rt, extract dpump

  1. GGSCI> edit params dpump

                      Extract dpump
                      userid gguser@SRC,password oracle
                      rmthost 192.168.162.13,mgrport 7810
                      rmttrail /u01/app/oracle/GG/dirdat/ptrail/rt
                      passthru
                      table sender.empl;

On TRGT

1.    GGSCI> add replicat repldml, exttrail /u01/app/oracle/ GG/dirdat/dptrail/rt,checkpointtable gguser.chkptab

2.    GGSCI> edit params repldml

                        replicat repldml
                        userid gguser@TRGT,password oracle
                        ASSUMETARGETDEFS
                        MAP sender.empl, TARGET receiver.empl;

    
    On SRC

  1. GGSCI > start extract extdml

 2. GGSCI> start extract dpump
    
    On TRGT

     1.  GGSCI> start replicat repldml    


Do some insert and update on SRC table which should be reflected on TRGT automatically.

====================================================



Schema Replication through Datapump


Sample Table structure:
===============
Create table sender.empl (empid number(10),empname varchar2(10),constraint emp_key unique(empid));

Create table receiver.empl (empid number(10),empname varchar2(10),constraint emp_key unique(empid));

Create table sender.company (city varchar2(10),pincode number(10),constraint pin_key unique(pincode));

Create table receiver.company (city varchar2(10),pincode number(10),constraint pin_key unique(pincode));



Prerequisite:
========

Create a directories  “ mkdir /u01/app/oracle/GG/dirdat/schtrail/“  &
