If you are familiar with using Oracle GoldenGate, you know that on the source side of the equation you have to enable supplemental logging and sometimes force logging on the database. I traditionally do both just to make sure that I capture as much as I can into the redo stream from the transactions on the database. For Oracle GoldenGate purposes, this is not the only thing you need to turn on to ensure all needed information is captured to the trail files.
There are two Oracle GoldenGate GGSCI commands that can be ran to enable supplemental logging at the schema or table level. These commands are ADD TRANDATA and ADD SCHEMATRANDATA. What is the difference between the two, you may ask?
ADD TRANDATA – is used to enable supplemental logging at the table level
ADD SCHEMATRANDATA – is used to enable supplemental logging at the schema level
That is such a high-level view of the concept. What is the difference between the two trandata approaches, really?
ADD TRANDATA:
ADD TRANDATA command is used to enable Oracle GoldenGate to acquire the transaction information that it needs from the transaction records. This version of the command can be used on the following databases:
- DB2 for i Database
- DB2 LUW Database
- DB2 z/OS Database
- Oracle Database
- MS SQL Server
- Sybase Database
For an Oracle Database, ADD TRANDATA enables the unconditional logging of the primary key and conditional supplemental logging of all unique key(s) and foreign key(s) of the specified table. Additionally, you can use ADD TRANDATA with the COLS option to log any non-key columns that can be used with the FILTER statements and KEYCOLS clauses in the TABLE and MAP parameters.
An example of adding trandata to a schema would be:
GGSCI> dblogin useridalias gate GGSCI> add trandata soe.*
Once transdata has been added to the schema/tables, you can verify the existence of trandata from GGSCI using the INFO TRANDATA command as demonstrated in the below command set.
GGSCI> dblogin useridalias gate GGSCI> info trandata soe.addresses 2016-08-12 15:07:23 INFO OGG-06480 Schema level supplemental logging, excluding non-validated keys, is enabled on schema SOE. 2016-08-12 15:07:23 INFO OGG-01980 Schema level supplemental logging is enabled on schema SOE for all scheduling columns. Logging of supplemental redo log data is enabled for table SOE.ADDRESSES. Columns supplementally logged for table SOE.ADDRESSES: ADDRESS_ID, COUNTRY, COUNTY, CUSTOMER_ID, DATE_CREATED, HOUSE_NO_OR_NAME, POST_CODE, STREET_NAME, TOWN, ZIP_CODE.
Now that ADD TRANDATA has been ran, what exactly does ADD TRANDATA do to the database it is ran against? For an Oracle Database, ADD TRANDATA adds a Supplemental Log Group (SLG) on to the table. This can be seen from the DBA_LOG_GROUP view under SYS. The SLGs that are corrected are all labeled with a prefix of “GGS”. The following output shows what this looks like after running it for a whole schema.
select owner, log_group_name, table_name, log_group_type, always, generated from dba_log_groups where owner = 'SOE' and log_group_name like 'GGS%';
Now, there are some who will argue that the same effect can be done by just asking a SLG to a table manually. Although this is true, Oracle GoldenGate uses the GGS_ prefix to keep track of the tables that are in the replication process. Also, easier to clean up when you issue DROP TRANDATA, which will remove all the associated SLG items from the tables.
The ADD TRANDATA approach should be used with 11g or older versions of Oracle GoldenGate. As you move towards new version of Oracle GoldenGate, Oracle is pushing that everyone pick up and use the ADD SCHEMATRANDATA method. So let’s take a look at that now.
ADD SCHEMATRANDATA:
The ADD SCHEMATRANDATA is used on all the current and future tables in a given schema to automatically log a superset of available keys that Oracle GoldenGate needs for row identification. Using this version of TRANDATA, it can be used with both the integrated and classic capture processes.
There are four key reasons why you should use ADD SCHEMATRANDATA:
- Enables supplemental logging for new tables created with a CREATE TABLE DDL command.
- Updates supplemental logging for tables affected by an ALTER TABLE DDL command that adds or drops columns
- Updates supplemental logging for tables affected by RENAME TABLE command
- Updates supplemental logging for tables affected by adding or dropping of unique or primary key constraints
Although ADD SCHEMATRANDATA can be used with both integrated and classic capture processes, it is mostly geared towards the integrated process. There are three primary reasons to use ADD SCHEMATRANDATA with the integrated capture:
Ensures that the correct key is logged by logging all the keys
Options are provided that enable the logging of the primary, unique, and foreign keys to support the computation of dependences among the tables being processed by the integrated replicats (think apply servers)
Ensures the appropriate key values are logged in the redo to allow DML to be mapped to object that have DDL issued against them.
Earlier in this post, I mentioned that I often enable “force logging” on the database when I do the minimal supplemental logging. Force logging is encouraged by Oracle, especially when using ADD SCHEMATRANDATA.
Now to add issue ADD SCHEMATRANDATA against an Oracle database, it is similar the same way as ADD TRANDATA, with the difference that you don’t have to provide any wildcards. In the examples below, I show you how this can be done:
GGSCI> dblogin useridalias ggate GGSCI> add schematrandata soe 2016-08-12 15:47:40 INFO OGG-01788 SCHEMATRANDATA has been added on schema soe. 2016-08-12 15:47:40 INFO OGG-01976 SCHEMATRANDATA for scheduling columns has been added on schema soe.
After running ADD SCHEMATRANDATA, you can perform an INFO SCHEMATRANDATA on the schema to see what has been modified.
GGSCI (fred.acme.com as ggate@src12c) 9> info schematrandata soe 2016-08-12 15:51:52 INFO OGG-06480 Schema level supplemental logging, excluding non-validated keys, is enabled on schema SOE. 2016-08-12 15:51:52 INFO OGG-01980 Schema level supplemental logging is enabled on schema SOE for all scheduling columns.
Digging around in the database, to see if ADD SCHEMATRANDATA does the same as ADD TRANDATA with SLG; well, it doesn’t. ADD SCHEMATRANDATA does not create any SLGs. The only place that I have found that has any record of supplemental logging turned on with ADD SCHEMATRANDATA is in the V_$GOLDENGATE_CAPABILITIES view. Here, you can see that supplemental logging has been enabled, the number of times it has been acted upon and when it was last executed.
NAME COUNT TO_CHAR(LAST_USED CON_ID ---------------------- ---------- ----------------- ---------- DBENCRYPTION 0 12-JUN-2016 21:20 0 DBLOGREADER 0 12-JUN-2016 21:20 0 TRIGGERSUPPRESSION 0 12-JUN-2016 21:20 0 TRANSIENTDUPLICATE 0 12-JUN-2016 21:20 0 DDLTRIGGEROPTIMIZATION 0 12-JUN-2016 21:20 0 GGSESSION 0 12-JUN-2016 21:20 0 DELETECASCADEHINT 0 12-JUN-2016 21:20 0 SUPPLEMENTALLOG 5 12-AUG-2016 16:02 0
Now, being that the integrated items of Oracle GoldenGate are closely related to Oracle Streams, there may be a table or view related to Streams that has this information. Once I find it, I’ll provide an update to this post.
In the mean time, I hope this post has provided some insight into the differences between ADD TRANDATA and ADD SCHEMATRANDATA.
If you are moving to or using the integrated products of Oracle GoldenGate, then ADD SCHEMATRANDATA is the method that you should be using.
Enjoy!!!

Efficient Steroids Cutting Cycle Guide For Lean Muscle
Efficient Steroids Cutting Cycle Guide For Lean Muscle
### Key Takeaways
Anabolic steroids have long been a staple in the world of bodybuilding,
offering individuals the ability to enhance
muscle growth and definition. However, their use must be approached with caution and a
thorough understanding of how they work and impact the body.
### Understanding Steroids and Their Role in Bodybuilding
Anabolic steroids are synthetic substances that mimic the effects of testosterone, a
hormone naturally produced by the body. Testosterone is responsible for muscle growth,
fat metabolism, and various other physiological processes.
While natural testosterone levels decline with age, anabolic steroids can provide
a boost, enabling users to achieve leaner muscles and a more defined physique.
### What are Anabolic Steroids?
Anabolic steroids are man-made variants of testosterone
that have been altered to mimic the hormone’s muscle-building effects more efficiently.
They are often used in cutting cycles, where their primary purpose is to strip excess fat while maintaining or even increasing
muscle mass.
### How Do Steroids Work for Muscle Growth?
Steroids work by binding to androgen receptors in cells,
signaling the body to synthesize proteins and promote muscle growth.
This process is amplified when steroids are used in conjunction with intense resistance training,
which creates a hypertrophic response in the muscles.
### Factors to Consider for an Effective Cutting Cycle
A successful cutting cycle hinges on several factors, including
individual goals, experience level, and adherence to proper protocols.
Women often prefer different compounds than men due to
differences in muscle physiology and hormone levels.
### Gender Differences in Steroid Use
While anabolic steroids can be used by both genders, the effects are typically more pronounced
in men. Women may find milder or gender-specific
formulations more suitable for their needs, as higher doses
of traditional anabolic steroids can lead to unwanted side effects like deepening of voice or increased facial hair.
### Experience Level and Its Impact on Cycle
Selection
Newcomers should start with shorter cycles and lower dosages to assess their tolerance and response before moving to longer or more
potent regimens. Experienced users may opt for extended cycles to achieve peak conditioning, but this requires careful monitoring and planning.
### Aligning Steroid Use with Fitness Goals
The choice of steroid compounds and cycle duration should align with the user’s fitness objectives.
For example, a competitive bodybuilder might require a different approach
compared to someone looking to enhance personal fitness.
### Choosing the Right Steroids for Cutting
When it comes to selecting steroids for cutting, users often prioritize compounds
with strong fat-burning effects while maintaining muscle mass.
Testosterone enantate and boldenone are popular choices for
their ability to promote lean muscle growth while stripping excess body fat.
### Popular Steroid Compounds for Cutting Cycles
– **Testosterone Enantate**: A long-acting steroid that provides a steady supply of testosterone, supporting muscle maintenance and fat
loss.
– **Boldenone**: Known for its ability to enhance muscle definition and promote fat oxidation.
### Comparison of Oral vs. Injectable Steroids
Injectable steroids are generally preferred by serious users due to
their consistent release and reduced side effects compared to oral forms.
However, both have their place in a cutting cycle, depending on individual preferences and tolerance.
### Steroids Cutting Cycle: Planning Your Cycle
A well-planned cutting cycle begins with determining
the appropriate length and dosage. While cycles can vary, a common approach is to use injectable steroids
for 8-12 weeks, accompanied by a structured workout
plan and diet.
### Length and Dosage Recommendations for Cutting Cycles
Dosage should be calculated based on individual response,
starting with lower doses to assess tolerance before
increasing. The cycle length may range from 4 to 16 weeks, depending on goals and experience level.
### Beginning a Cutting Cycle: What to Expect
Users can expect significant muscle definition within the first few weeks,
along with increased energy levels. However, this is often accompanied by temporary side effects like acne or hair loss, which typically subside
as the body adjusts.
### Monitoring and Adjusting Your Cycle
Regular monitoring of progress and health indicators is crucial.
Blood work to check hormone levels can provide valuable insights, allowing adjustments to be made
as needed.
### Buy 2, Get 1 Free + Extra 20% Off Limited Time Offer
Take advantage of exclusive offers available from trusted suppliers to enhance your cutting
cycle experience at a better value.
### Minimizing Risks During a Cutting Cycle
While steroids are effective, they do carry risks.
Users should prioritize obtaining their compounds from reputable sources to reduce the likelihood of
counterfeit or contaminated products.
### Proper Nutrition and Training During the Cycle
A cutting cycle is not just about steroid use; it requires a disciplined approach to diet and training.
Consistent protein intake, calorie control, and intensity in workouts are essential for maximizing
results.
### Understanding Potential Side Effects
As with any exogenous hormone, steroids carry potential side effects,
including hormonal imbalances, liver stress, and changes in cholesterol levels.
Users must be prepared to manage these risks through appropriate supplementation and monitoring.
### Post-Cycle Therapy (PCT) Considerations
After completing a cutting cycle, a post-cycle therapy plan is often employed to restore natural hormone production and avoid a hormonal imbalance.
This typically involves using compounds like Clomid or
Nolvadex to stimulate testosterone levels.
### Conclusion
An efficient steroid cutting cycle is the result of meticulous planning,
proper adherence, and an understanding of how these hormones interact
with the body. By aligning their use with fitness goals and maintaining a
healthy lifestyle, users can achieve lean muscle while
minimizing risks.
