Add tables to an Existing GoldenGate Configuration - Oracle Golden Gate

 1.     Log into the source database via GGSCI


[oracle@blue ggate]$ ggsci


Oracle GoldenGate Command Interpreter for Oracle

Version 11.2.1.0.13 17435036 OGGCORE_11.2.1.0.0OGGBP_PLATFORMS_131002.1206_FBO

GGSCI (blue.color) 2> dblogin userid ggate, password ggate

Successfully logged into database.


2.     Add trandata for the new table(s).


GGSCI (blue.color) 3> add trandata song.stone


2013-12-05 15:17:07  WARNING OGG-00869  No unique key is defined for table 'STONE'. All viable columns will be used to represent the key, but may not guarantee uniqueness.  KEYCOLS may be used to define the key.


Logging of supplemental redo data enabled for table SONG.STONE.


GGSCI (blue.color) 4> add trandata song.greystreet


2013-12-05 15:17:15  WARNING OGG-00869  No unique key is defined for table 'GREYSTREET'. All viable columns will be used to represent the key, but may not guarantee uniqueness.  KEYCOLS may be used to define the key.


Logging of supplemental redo data enabled for table SONG.GREYSTREET.


3.     Add the two tables in the Extract Parameter file


GGSCI (blue.color) 5> edit params e_gg

...

TABLE song.stone;

TABLE song.greystreet;

...


4.     Restart the Extract e_gg


GGSCI (blue.color) 2> stop e_gg


Sending STOP request to EXTRACT E_GG ...

Request processed.



GGSCI (blue.color) 3> start e_gg


Sending START request to MANAGER ...

EXTRACT E_GG starting


5.     At this point, capture the Current SCN from the database. Do not lose this number, we need it later!

8.     Here’s the important step, you need to edit the replicat’s parameter file and include the following string in the map statement.


GGSCI (blue.color) 2> edit params r_gg

...

MAP song.stone, TARGET river.stone , FILTER ( @GETENV("TRANSACTION", "CSN") > 1113396);

MAP song.greystreet, TARGET river.greystreet, FILTER ( @GETENV("TRANSACTION", "CSN") > 1113396);

...


9.     Recycle the replicat.


GGSCI (blue.color) 4>  stop r_gg


Sending STOP request to REPLICAT R_GG ...

start Request processed.



GGSCI (blue.color) 5> start r_gg


Sending START request to MANAGER ...

REPLICAT R_GG starting


GGSCI (blue.color) 6> info all


Program     Status      Group       Lag at Chkpt  Time Since Chkpt


MANAGER     RUNNING                                           

EXTRACT     RUNNING     E_GG        00:00:00      00:00:09   

REPLICAT    RUNNING     R_GG        00:00:00      00:00:03   


10. Check the counts on both systems.


10.1. On the Source


SQL> select name from v$database;


NAME

---------

SKY


SQL> select count(1) from song.stone;


  COUNT(1)

----------

       100


10.2. On the Target


SQL> select name from v$database;


NAME

---------

WATER


SQL> select count(1) from river.stone;


  COUNT(1)

----------

       100


10.3. Insert data on the source.


SQL> INSERT INTO song.stone

SELECT dbms_random.string('A', 2) RNDMSTR

  FROM all_objects

 WHERE ROWNUM < 101;  2    3    4 


100 rows created.


SQL> commit;


Commit complete.


SQL> select count(1) from song.stone;


  COUNT(1)

----------

       200


10.4. Check the counts on the target table.


SQL> select count(1) from river.stone;


  COUNT(1)

----------

       200


10.5.  Check lag on the replicat.


GGSCI (blue.color) 1> info all


Program     Status      Group       Lag at Chkpt  Time Since Chkpt


MANAGER     RUNNING                                          

EXTRACT     RUNNING     E_GG        00:00:00      00:00:02   

REPLICAT    RUNNING     R_GG        00:00:00      00:00:08   


11.     Once the table is caught up, remove the FILTER parameters from the replicat.


GGSCI (blue.color) 2> edit params r_gg

...

MAP song.stone, TARGET river.stone;

MAP song.greystreet, TARGET river.greystreet;

...


12.     Restart the replicat and we’re done!


GGSCI (blue.color) 4>  stop r_gg


Sending STOP request to REPLICAT R_GG ...

start Request processed.



GGSCI (blue.color) 5> start r_gg


Sending START request to MANAGER ...

REPLICAT R_GG starting


GGSCI (blue.color) 6> info all

REPLICAT    RUNNING     R_GG        00:00:00      00:00:02

How to Solve - "WAIT FOR EMON PROCESS NTFNS"

Event Monitor Process in short called as EMON is generally used by oracle to send notification. Often applications uses Database Change Notification process also called as DBCN to be aware of changes in the database, based on these notifications they take further actions. Often clients subscribe to the database and notifications are send as callback to them. In some cases you will notice database sessions are showing wait event "WAIT FOR EMON PROCESS NTFNS" and it can even make your database un-responsive. One observation can be these processes are taking more CPU (may not in be in all cases). As stated EMON process deals with database notification and it's spawn and gets down itself and Administrators have no control on theses processes. Anyone can go through oracle documents to read more EMON functioning process.  EMON uses oracle advanced queues and database queue notifications into them and EMON process these notifications to clients based on their subscriptions.

Query Regression - "OR" Transformation Oracle 19c

Recently while upgrading Oracle Database from version 12.1 to 19.10 found there were couple of queries which was running slow post upgrade. Usually these type of behavior is seen while upgrading to newer version and oracle provide various ways to fix them. The difference between good and bad plan was an introduction of  "MERGE JOIN CARTESIAN" (aka MJC) and that's in where regressed query in 19c taking most of the time. MJC sometimes works for queries but in this case it was clearly not helping.  We had following options here:     1. Copy the profile from 12c to 19c database and it worked, but the problem was not just to specific query but with many similar query. This means profile option is not very attractive in this case.     2. We also tried running query with OFE 12.1 to use the same optimizer features as previous version and query behaves well. Though this option can't be placed as we need to use 19c OFE and can be placed only for testing purpose. ...

Error Processing Request. - Oracle APEX Post upgrade (Invalid WWV_FLOW_SESSION_RAS)

There would be occasions where you would upgrade your oracle database which is hosting your APEX and post upgrade you get error while opening APEX URL " Error Processing Request Contact your application administrator " This looks very strange as you have just upgraded only database. Database version and APEX version are compatible. For Argument lets say both are on 19c.  Now since UI doesn't give detailed information about the error you would need to get to backend oracle database and query view apex_debug_messages.     select * from apex_debug_messages; Looking at the results of this view you would get the clue of the error in this case it was:      ORA-04063 package body APEX_190100.WWV_FLOW_SESSION_RAS has error This means this package body has problem and looking at the status of this body it's found to be invalid and when you try to compile it get following error      alter package APEX_050100.WWV_FLOW_SESSION_RAS compile body;  ...
