Oracle DWH or OLTP
Hello
is my version of oracle: Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64 bit Production
I would check if the connected database is DWH (DSS) or OLTP
Should what settings I check to see if the Oracle database is DWH (DSS) or OLTP?
Thanks in advance!
None of them. There is no parameters that will tell you how the database is used. In fact, a single database can be used for the server these two purposes.

Behavior in Oracle 11g R2 OLTP
Hello world.
Could someone explain this behavior.
I have three tables, one in compression OLTP, other basic compression and no compression on the other.
When I inserted on OLTP table lines, these lines are not compressed.
Only after doing a 'move' segment is shrinking.
My test cases (Oracle 11.2.0.3.8):
As you can see here, even after moving to compress to oltp, always the same space.create table a_normal as select rownum id, a.* from all_objects a / create table a_compress as select rownum id, a.* from all_objects a / create table a_comp_oltp as select rownum id, a.* from all_objects a / SQL> alter table a_compress move compress; Table altered. SQL> alter table a_comp_oltp compress for oltp; Table altered. SQL> select table_name, compression, compress_for, pct_free from dba_tables where table_name in ('A_COMPRESS','A_COMP_OLTP','A_NORMAL'); TABLE_NAME COMPRESS COMPRESS_FOR PCT_FREE ------------------------------ -------- ------------ ---------- A_NORMAL DISABLED 10 A_COMP_OLTP ENABLED OLTP 10 A_COMPRESS ENABLED BASIC 0 SQL> select segment_name, bytes/1024 from dba_segments where segment_name in ('A_COMPRESS','A_COMP_OLTP','A_NORMAL'); SEGMENT_NAME BYTES/1024 --------------------------------------------------------------------------------- ---------- A_COMP_OLTP 10240 A_COMPRESS 3072 A_NORMAL 10240
Now, after the 'move', our space is shrinking.
And, after that, I inserted 4 million without adding lines and more than 4 million with append, both are not compressed until before I did a "move".SQL> alter table a_comp_oltp move; Table altered. SQL> select segment_name, bytes/1024 from dba_segments where segment_name in ('A_COMPRESS','A_COMP_OLTP','A_NORMAL'); SEGMENT_NAME BYTES/1024 --------------------------------------------------------------------------------- ---------- A_COMP_OLTP 4096 A_COMPRESS 3072 A_NORMAL 10240
When I read the documentation, he said: "when a block reaches the PCTFREE value, it will be compressed, if do the compression of the leaves block the PCTFREE threshold, it will be can accept more lines and make the compression again."SQL> @ins_a_comp_oltp Enter value for 1: 4000000 old 3: l_rows number := &1; new 3: l_rows number := 4000000; Enter value for 1: 4000000 old 9: where rownum <= &1; new 9: where rownum <= 4000000; PL/SQL procedure successfully completed.

SQL> select segment_name, bytes/1024 from dba_segments where segment_name in ('A_COMPRESS','A_COMP_OLTP','A_NORMAL'); SEGMENT_NAME BYTES/1024 --------------------------------------------------------------------------------- ---------- A_COMP_OLTP 665600 A_COMPRESS 3072 A_NORMAL 499712 SQL> alter table A_COMP_OLTP move; Table altered.

But here, even with a 4 million, the table insert is not compressed, nor with append (direct route), why?
Thank you and best regards,
Felipe.
Published by: Felipe Romeu on 10/09/2012-14:43Hi Felipe,.
The same issue happened to me some time ago. The problem was that I was using the sys as sysdba user. When I used the system of the user of the problem did not happen again.
What user of oracle database do you use?Kind regards

Published by: hqt200475 on Sep 14, 2011 09:04If I understand the second part of the question, you can use DBMS_SERVICE to create an alias on both servers.
Then according to the ROLE they are in you can just connect.
First of all an entry should be added to the tnsnames.ora to client that uses a SERVICE_NAME instead of a SID.
ernie = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = primary.host)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = standby.host)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = ernie) ) )Then, the "ernie" service must be manually created on the primary database.
BEGIN DBMS_SERVICE.CREATE_SERVICE('ernie','ernie'); END; /After creating the service must be started manually.
BEGIN DBMS_SERVICE.START_SERVICE('ernie'); END;Several of the default settings can now be set for "ernie".
BEGIN DBMS_SERVICE.MODIFY_SERVICE ('ernie', FAILOVER_METHOD => 'BASIC', FAILOVER_TYPE => 'SELECT', FAILOVER_RETRIES => 200, FAILOVER_DELAY => 1); END; /Finally a trigger to START database should be created to ensure that this service is only available if the database is the main.
CREATE TRIGGER CHECK_ERNIE_START AFTER STARTUP ON DATABASE DECLARE V_ROLE VARCHAR(30); BEGIN SELECT DATABASE_ROLE INTO V_ROLE FROM V$DATABASE; IF V_ROLE = 'PRIMARY' THEN DBMS_SERVICE.START_SERVICE('ernie'); ELSE DBMS_SERVICE.STOP_SERVICE('ernie'); END IF; END; /Check the status using lsnrctl status
/ home/oracle: > lsnrctl status
"Ernie" service has 1 instance (s).
Stone comes from the Oracle example, you can add anything you want, and then if you make a passage or failover, it is transparent to your users.

Hello forum
IM new in oracle form and have some confusion on the use of oracle web application forms. can someone tell me pls why use forms oracle instead of many web technologies such as asp, c#, php, Jsp? as forms are heavy, and takes a long time to load then why should I use it?
can I use oracle applications forms such as public web applications where anyone can use this application? but given this ive another confusion! all users will need to install OC4J for execution of oracle forms? If they do then its going to be a very big hassle for users.
in fact, I want to know the basic concept of using oracle forms...Depends on your application needs, if you are developing Web sites, with a very weak interaction with a database, move away Oracle forms to Oracle Apex and database 10 g XE.
If you develop an ERP application or any other that interacts strongly with the database (Oracle db) and OLTP performance, validation data and the operations processing and others, then you must use Oracle Forms.
And as it is stated in the above post forms based on SQL and PL/SQL languages and its executables are interpreted at run time, it is not an exe file, it can be maintained more easily, you can take a form offline and the rest of your application would be quite normal.Some people may say forms has its limits, but with PJCs and Java Beans I couldn't find a limitation that cannot be conquered.
Users who run an Oracle web application need not run OC4J at the same time, you must OC4J only if you will be running your form with the manufacturer of forms, or for testing purposes.
For a production deployment, you will need an OAS Oracle applications server and users should only auto-télécharger/install JInitiator the first run of the application only after the first time it works magically.Tony

It is not a mystery, but it's something of undocumented.There is a moment ago, I got the same curiosity when I saw an unknown PMON process on my host.
I noticed that initializing DBCA, or the Oracle DBUA always creates a temporary instance named DBUAin a short period, for internal reasons, it also saves a service on the port to listen temporarily. This dummy instance is started to determine what options are available for DBCA use it. This instance is created and deleted in a few seconds, to run two select "select the option setting of $ v where the value = 'TRUE'" and "select version of v$ timezone_file.
Start dbca and check the pmon process.
You will see something like this:
$ ps -ef |grep pmon oracle 2485 1 4 23:14 ? 00:00:00 ora_pmon_DBUA0For more information, see the trace log that is played during the DBCA runs.

How to filter the by using (-) less symbol.
Hello
We use oracle EBS as OLTP. Sale of data stores the PO_HEADERS_ALL, PO_LINES_ALL table, which contains data of rejection/cancellation order.
Rejected/cancelled in data store also the same tables. We are able to identify the base denied/cancelled quantity indicated (-) less symbol. (Example: Qty:-30), and the Amount column is also indicated as (-) less symbol. So, how to filter the data on quantity everything is indicated - less symbol in OBIEE.
Kind regards.
CHRJay wrote:
IF it is set to digital use function of cast to convert to a char, then using as check the reason for the less to be filtered in the filter condition formula.If you want to filter all values of negetive, then use filter: measure<0 in="" filter="">
Hope this will help you.
Thank you
Jay.If the column was purely digital, why cast to CHAR? The OP can do everything suggested Robert Angel. My suggestion was where there was some other non-numeric values in the column that could be the reason why the column is CHAR, then using the SIMILAR filter operand would solve this problem.
The first part of your suggesting was not necessary if the column is a numeric data type and the second part was just a repetition of what Robert.

Solution to run sql of mysql application logs
We have a custom application to mysql, which generate logs stored in a common location on the linux machine that has format below open
$ cat minor20100809.log
20100809001 ^ Âselect (prod_id) count of product_logs;
20100809002 ^ Âselect (order_id) count of order_logs;
ID and the SQL with command A seperater and 1000 daily newspapers files are generated
We now have an oracle DWH, where import us all the data from mysql, and we need to test these counts on a daily basis.
Could you please suggest a solution in oracle for this?
high level, to follow the procedure below
(a) import only those log files in a table-> which is the best way sqlldr, impdp or plsql read file?
(b) execute these sql one statement
(c) store the counties table of daily newspaperWhat is a "tool for oracle? You have SQL * Loader on your client machine? SQL * more? Are you allowed to use these tools? What possible safety reason can there be for you to use certain tools on the client machine, but not others?

Hello
I asked about the best way to implement the logic of transformation with OWB. In my case, the source is a database and the amount of data is only a little more than 2 million lines. Extract phase I did a direct load from the source to the table in ITS phase where the table is structured the same as the source. Type of loading is TRUNCATE/INSERT. It takes two minutes to load which I think is pretty well in our environment. I've been making mappings that takes the data from the table - its, makes all the transformations and save a direct result of the dw-table (UPDATE/INSERT). All in a map. But when there is a lot of transformation in several expressions with box-when a lot of joins clauses and the research, the result is very inefficient - I think - can not be solved by tuning the plan of the explain command. I also include the surrogate_id in the Web of mapping (we do not use object dimension or cube objects, a few tables). There are situations where the data used in the expression are handled several times in the other expression which - I think - a lot of handling nested in the package. Time to update the dw table can be found on several hours... I think my mistake is trying to put too many things in the unique mapping when the order of operators can be found on the inefficient code.
I was told that the best way to manage data is to extract the data from the source to the table - its is construced as dw-table. I know people who did the tampering in separate SQL clauses in a PL/SQL procedure. Do a lot of updates for SA table. The only thing to do with OWB is to transfer the data from the table'S ready at the DW table. I don't bite. I tend to think that the transformation is always possible more effective with OWB (if the mapping is designed right way) because overall according to the mode that it generates only one article SQL to do any manipulation in the unique map. Is it? I wonder three different things:
(1) when to split the map to separate mappings.
(2) can I do maps update the original table with loading type updated or are still transferred directly mappings that stores the results in the new table?
(3) the use of tables in ITS region. When I should make transformation multimode (do more sa-tables to store the incremental result of each step)?
I think that it is difficult to clarify me on this. I hope you get my point and can give me some good guidelines to follow.
Kind regards
JuhaHi Juha,
It is not the order or the use of simple operators that make the mapping of poor performance but operations temporarily stores the data on the disc are those should I avoid - or try to minimize their effect.
Temporary tablespace using Oracle DWH (and perhaps on other RDBMS platforms) is general. I think that it is very difficult to avoid completely the temporary segments creting in environment DWH.
Or maybe I should concentrate on the path I have chosen and separate big joins on their own mappings and reduce the amount of joints in a mapping?
In my view, splitting complex mapping in several mappings is the best approach in your case.
Kind regards

Hello
We use the ODI to load some data from an Oracle ERP to an Oracle DWH. How should we define the index? Should we create them physically when you create tables DWH or should I use the KM to dynamically set?
Thank youHello
ODI is not made for the administration of the DBMS. It is better to manage the indexes directly in Oracle and return to them. If you don't do this, you cannot use the incremental update IKM requiring unique indexes.

Informatica is a product of Oracle?
Hello
I was searched on the net, what is the relationship between Informatica and Oracle, but I've not found any results
The question why I am looking for this information?
Because I found two days ago I can download information from the oracle site https://delivery. Oracle.com and now I'm looking what is the relationship between Informatica and Oracle
Thank you
Informatica is not a product of Oracle.
But for OLIVIER Oracle was using Informatica as ETL to move data between sources and the DWH OBIA (I guess it's OLIVIER * 7.9.6).
In the latest version of OLIVIER (11) Oracle replaced by ODI, their own ETL Informatica.
So you can download Informatica from the oracle site in old 7.9.6 * OLIVIER OLIVIER pack, but it is not at all a product of Oracle.

'compressed_for' has changed from OLTP (11g) to ADVANCED (12 c) after expdp/impdp
After the export multiple tables compressed 11g and import in 12 c by datapump, column "compress_for" (dba_tables) changed OLTP (11g) to ADVANCED (12 c).
Does anyone know if "compressed_for" OLTP is obsolete in 12 c? Is there an impact on this change?
Thank you, Mike.
Of the doco:

I would say that the advanced compression includes compression OLTP, you need the license of advanced compression to use.

VECTOR_TRANSFORM and ORACLE 12 c InMemory
Patch level: "game of hotfixes in the OCW - updated: 12.1.0.2.4 (20831113).
Like many people I guess, I just upgraded an existing DWH, I set some 12 c in memory settings and expect significant performance improvements.
It did not.
So I decided to build a DWH sample with a time and the product dimension and a partitioned fact table that is so great that it would not completely fit in the inmemory part, to do some tests in a much simpler environment.
In my example, the dimensions are first loaded in memory in priority. The fact load depends on the use of partitions so that the 'real' data will not fit.
Questions I wanted to answer were:
1. the inmemory query will be much faster than the no version inmemory. (Answer: it depends.) It is often not!)
2 done ORACLE Exchange will introduce INMEMORY partitions when there is no more space and
other data partitions (for example in the form of a FIFO?), we wonder. (Answer: no, this is documented)
3. will I see in v$ im_segments I have no partitions of all the senses in memory
(No you need to associate DBA_SEGMENTS to see the partitions in memory.)Now, I tried to find out why I have no more success.
And while I played and I read, I found VECTOR_TRANSFORM
https://support.Oracle.com/epmos/faces/DocumentDisplay?_afrLoop=287258785184897 & ID = 1935305.1 & _afrWindowMode = 0 & _adf. CTRL-State = 15o1gcrocb_55
WHO gave a real helping hand to my request! (when the optimizer takes)I set myself (to have always to all my normal queries of DWH)
change all of the "_always_vector_transformation" system = true;
change the whole system "_optimizer_vector_cost_adj" = 20;But it does not work for all queries.
So I decided to share my findings with you and ask if anyone knows why ORACLE here sometimes decide not to use VECTOR_TRANSFORM.
I have found too much examples of work on the WEB that really show the difference in performance of INMEMORY. I did it here hope for other examples of work / tips etc.
Here in short my tests and you see that I am MUCH faster when both functions are used.
Without VECTOR_TRANSFORM and INMEMORY
Elapsed time: 00:00:38.56
A query that takes VECTOR_TRANSFORM and INMEMORY is:
Elapsed time: 00:00:00.75 < = factor 50 and VERY impressive!
Without VECTOR_TRANSFORM with INMEMORY
Elapsed time: 00:00:09.32
Even if the fact is not in memory query takes:
Elapsed time: 00:00:02.79Then, as my system memory is limited, I would put all the dimensions of INMEMORY and
hope that the VECTOR_TRANSFORM is ALWAYS usedBut even I put '_always_vector_transformation' and give a clue VECTOR_TRANSFORM.
VECTOR_TRANSFORM is sometimes not used.I put the events below to get an answer and checked the trace:
ALTER session set events trace [SQL_Transform.*] ' disk 'high '.
ALTER session set events trace [SQL_Costing.*] ' disk 'high '.but that didn't help either. (too much information ;-)

/Andy,
I built your model with a few adjustments and played a little bit.
I did not have the dimensions in memory and I added an extra column to the product dimension, and I built only 254 partitions (so all in 2005)
I think the optimizer ignores the vector transformation because he decides that your request is not a query group. Your entry is:
Select
-min (d.day_id), max (d.day_id),
d.Year, p.product_type, sum (f.sale_price) sale_price, count (*)
of day_dimension d
sales_fact f d.day_id = f.day_id inner join
inner join product_dimension p on p.product_id = f.product_id
where d.year = 2012 and p.product_type = 'TABLE '.
D.year group, p.product_type
d.year order, p.product_type
The optimizer rewrites that:
Select
2012, 'TABLE', sum (f.sale_price) sale_price, count (*)
of day_dimension d
sales_fact f d.day_id = f.day_id inner join
inner join product_dimension p on p.product_id = f.product_id
where d.year = 2012 and p.product_type = 'TABLE '.
2012 group
It seems to me that if he had to eliminate "Group by constant", and it is strange that she keeps the first two columns (switch provided that the order in the group by and rewriting will be "Group by 'TABLE'")
I think that, even if, to some Oracle processes a query point block this exliminates that "group by" and disables VT accordingly.
My clue, incidentally was wrong, I realized it to @sel$ 1 when it should have been directed to joining 3 tables merged.
The subquery indicator (even if she had worn on the right query block) not would not have worked because it seems that creating a filter of Bloom for elimination of partition overrides subquery filtering - at least in 12.1.0.2 - and if the day_dimension is used as a table of accumulation, it is automatically able to generate a Bloom filter , and the no_px_join_filter() applies only for the join filter, not for the elimination of partition filter.
One thing I found with this request, however, is that if I disabled it partition pruning by filter Bloom (OPT_PARAM ('_bloom_pruning_enabled' 'false')) then, on the my data set, he ran a little faster. I would be interested in what he does on your game. (With statistics_level a new typical and no index of gather_plan_statistics). Possibly the most robust test would be the next set of indicators - to change the 'swap' to 'no_swap '.

The massive difference in timing is almost entirely due to statistics_level = all.
By operating without this parameter times were 1.58 and 1.23 seconds.
I think the reason why there is not a lot of information on the Internet, it is that he is still relatively new and there are not many people who use it, and those who use it are so happy to improve they get that they are not checking to see if they get all the improvement that could be expected. and the people who tend to look at these things had much else to look at again. I spent a bit of time looking at HOW it works, but I didn't spend time looking for cases where the strategy is rejected, or the methods of costing.

is an overall index provides fast response in OLTP times?
Hi all
I read a doc
http://docs.Oracle.com/CD/E18283_01/server.112/e16541/partition.htm#insertedID5
and it is said that If the application is an OLTP we and users needs quick response time, use an overall index
I don't know how an overall index provides quick access.
Assume there is a table and that is partitioned by hash.
This table has a local index on column owner - no partition key column.
To query the information of owner of SCOTT, Oracle will scan all index partitions that have given Scott.
On the other hand, there is an overall index on column 'owner '.
To query the information of SCOTT, Oracle probes also all index partitions that have given Scott.
So, here's the question.
Why everyone says that an overall index has good performance (response time) in OLTP?
Supplementary question
Similarly with above, there is a table copied from object. And the table is partitioned by hash (object_id).
To the query with where clause (where owner = xxx), If there is a local index, Oracle scans RANGE SCAN on the t_idx_local index in the first partition through the last partition (take a look at Pstart, Pstop)
But when Oracle uses the overall index, Pstart. Pstop column values are ' KEY | KEY "."
What does that mean??
Thank you.
The KEY to the formulation of the plan means that Oracle will use pruning partitiong dynamic rather than static.
Only it Oracle knows he can partition plum but it determines real partitions during execution, rather than during the analysis.
It's EXACTLY what you'd expect with an OVERALL index. Oracle search the index keys in the overall index and at this time there may find that some lines are in partition 13, others in the bulkhead 27, etc..
With a local index Oracle uses more generally STATIC pruning. You have a local index with a MONTHLY distribution key and your query wants all data of MAY. Oracle knows at the time you want the data for MAY and can use the data dictionary to determine what partitions have CAN data since the index INCLUDES partitiong keys.

HI: I analyze the STATSPACK report: this is the "volume test" on our UAT server for most of entry or "bind variables". Our shared pool is well used in oracle. Recovery of Oracle logs is not configured properly on this server, as in "Top 5 events of waiting", there are 2 for Oder.
I need to know what other information may be digging from of 'waiting in the foreground events' & ' background waiting events ", and which can help us better understand, in combination of ' Top 5 wait event, that how did the server test /? It could be overwhelming. wait events, so appreciate useful diagnostic or analyses. Database is oracle 11.2.0.4 updated from 11.2.0.3 on IBM AIX 64-bit, level 6.x system power

Hello
I think that your CPU is overloaded by your stress tests. You have one VCPU with 2 wires (2 LCPU), right? And the load average is greater than one. You have time DB which is not counted in (CPU time + wait events) and which comes no doubt from time spent in the runqueue.
> Oracle recovery logs is not properly configured on this server, as in "Top 5 events of waiting", there are 2 for oder
It is an error in statspack for show "log file parallel write here." This moment is historical and is included in 'log file sync '. And I don't think you have to redo misconfiguration. Waiting for 1ms to commit is ok. In OLTP you should have more than one validation in a user interaction so that the user don't worry not about 1 m in batch mode, unless you commit to each row, 1 DC to commit should not increase the total execution time.
The fact that you have a lot of line lock (enq: TX - line lock conflict) but very little time (on average 97 ms) is probably a sign that testers are running simultaneously a charge affecting the same data. Their set of test data is perhaps too simple and short. An example: when stress tests of an order entry system if you run 1000 concurrent sessions, ordering the same product to the same customer, you can get this kind of symptoms, but the test we unrealistic.
It's a high activity of 2000 calls per second, 52 transactions per second, user. But you also have low average active sessions, so the report probably covers a period of non-uniform activity, which makes the averages without meaning.
So note to tell about the events of waiting here. But we don't have any info about 39% of DB time devoted to the CPU which is where something can be improved.
Kind regards
Franck.
