How much time do you want to spend? I've been learning the Oracle internal architecture for over 20 years and there are still new things to learn. (Well ... it also depends on what you mean by 'internal architecture'.)
If you want the basics - the Oracle Documentation set at http://tahiti.oracle.com has a Concepts manual that does a decent job of describing the basic architecture. And the Windows Platform Guide, the Unix Administrator's Reference give a fair bit of additional information. As does the Oracle Networking reference.
And there are courses. Oracle University courses provide a decent overview of the architecture. And Jonathan Lewis, Richard Foote and others give excellent courses and seminars on specific aspects of the architecture.
ANd there are books. Search for books by Tom Kyte. Robert Stackowiak.
And internet search.

Hi Please,
Can please provide me Metalink id for Oracle database 11gR2 architecture.
Can please provide me Metalink id for Oracle database 12c architecture.

I do not believe you will find MOS Docs that describe the architecture. Have you checked the docs ? What specific information are you looking for ?

Three tier architecture using oracle dev suite 10g & oracle database 9i

hi ,
I am trying to build a software which will manage the database of a hospital through usual form design .
The tools I am using for these are
(1) oracle server database 9i (2) oracle developer suite 10g (3) windows xp professional service pack 2 .
I have designed the form modules in developer suite , created the tables in the database , connected those tables to the form modules using dml statements, now data can be inserted , updates and deleted through the form design . I have also deployed the forms using "run forms through web" and thereby other computers connected to the main computer through lan can also access the software using the web port address and the name of form to be used , these computers are not having oracle developer suite or oracle database installed , but they can access the software through the browser .
In this scenario my question is that , is this a three tier architecture as oracle database is the first tier , oracle developer suite is the middle tier where I am puting all the bussiness logics and oc4j instance is used to connect the database and the dev suite , and for user interaction we have the browser as the third tier ?
or this is a two tier architecture ? if this is a two tier architecture please let me know how can I implement a three tier architecture using oracle developer suite 10g and oracle server database 9i .
Thanks a lot for showing ur interest to read this

You need Oracle Application Server to deploy the forms when you go live.
What you are currently using OC4J which came in the developer suite. It is used only for development purpose and can not have capacity to handle higher load.
3 tier arch
1. Thin Client :-> Browser
2 Middle tier -> Oracle Appln Server /OC4j(in ur case)
3 Database Tier -> Oracle Database

Oracle Database Architecture Understanding

Hello everyone,
I am a newbie in Oracle arworld, and I want to learn ORACLE. A few months ago, I started to learn Oracle Database Architecture, and read a book. However, I forget much of that books after weeks ago, and read again forget again.. I could not make tangible Oracle DB in my mind. This situation really degrades my performance while working. For example a simple example; the books says;
Data Files:Every Oracle database has one or more physical data files, which contain all the database data. (physical storage structure)
Data Blocks: At the finest level of granularity, Oracle Database data is stored in data blocks.(logical storage structure)
Here, my mind is mixing. Both store data, so what is the difference. I want to go details of Oracle, in order to be successful. Please help me and suggest something to do.
Thank You

I do not believe you will find MOS Docs that describe the architecture. Have you checked the docs ? What specific information are you looking for ?

Internal Behaviour of Truncate Table Command in Oracle Database

Hi,
Can anyone let me know the internal behaviour of Truncate Table Command in Oracle Database?
Thanks,
Harshad.

Hi Tuhinshoor,
I know the functioning of Truncate Command.
But, I needed to know whether it drops the table before recreating it, maintaining all the indexes and constraints intact??
Thanks,
Harshad.

Connection pooling and auditing on an oracle database

Integration of a weblogic application with an oracle backend,
Connection pooling, and auditing ,2 conflicting requirements ?
Problem statement :
We are in the process of maintaining a legacy client server application where
the client is
written in PowerBuilder and the backend is using an Oracle database.
Almost all business logic is implemented in stored procedures on the database.
When working in client/server mode ,1 PowerBuilder User has a one-to-one relation
with
a connection(session) on the oracle database.
It is a requirement that the database administrator must see the real user connected
to the database
and NOT some kind of superuser, therefore in the PowerBuilder app each user connects
to the database
with his own username.(Each user is configured on the database via a seperate
powerbuilder security app).
For the PowerBuilder app all is fine and this app can maintain conversional state(setting
and
reading of global variables in oracle packages).
The management is pushing for web-based application where we will be using bea
weblogic appserver(J2EE based).
We have build an business app which is web-based and accessing the same oracle
backend app as
the PowerBuilder app is doing.
The first version of this web-based app is using a custom build connector(based
on JCA standard and
derived from a template provided by the weblogic integration installation).
This custom build connector is essentially a combination of a custom realm in
weblogic terms
and a degraded connection pool , where each web session(browser) has a one-to-one
relation
with the back end database.
The reason that this custom connector is combining the security functionality
and the pooling
functionality , is because each user must be authenticated against the oracle
database(security requirement)
and NOT against a LDAP server, and we are using a statefull backend(oracle packages)
which would make it
difficult to reuse connections.
A problem that surfaced while doing heavy loadtesting with the custom connector,
is that sometimes connections are closed and new ones made in the midst of a transaction.
If you imagine a scenario where a session bean creates a business entity ,and
the session bean
calls 1 entity bean for the header and 1 entity bean for the detail, then the
header and detail
must be created in the same transaction AND with the same connection(there is
a parent-child relationship
between header and detail enforced on the back end database via Primary and Foreing
Keys).
We have not yet found why weblogic is closing the connection!
A second problem that we are experincing with the custom connector, is the use
of CMP(container managed persistence)
within entity beans.
The J2EE developers state that the use of CMP decreases the develoment time and
thus also maintenance costs.
We have not yet found a way to integrate a custom connector with the CMP persistence
scheme !
In order to solve our loadtesting and CMP persistence problems i was asked to
come up with a solution
which should not use a custom connector,but use standard connection pools from
weblogic.
To resolve the authentication problem on weblogic i could make a custom realm
which connects to the
backend database with the username and password, and if the connection is ok ,
i could consider this
user as authenticated in weblogic.
That still leaves me with the problem of auditing and pooling.
If i were to use a standard connection pool,then all transaction made in the oracle
database
would be done by a pool user or super user, a solution which will be rejected
by our local security officer,
because you can not see which real user made a transaction in the database.
I could still use the connection pool and in the application , advise the application
developers
to set an oracle package variable with the real user, then on arrival of the request
in the database,
the logic could use this package variable to set the transaction user.
There are still problems with this approach :
- The administrator of the database can still not see who is connected , he will
only see the superuser connection.
- This scheme can not be used when you want to use CMP persistence , since it
is weblogic who will generate the code
to access the database.
I thought i had a solution when oracle provided us with a connection pool known
as OracleOCIConnectionPool
where there is a connection made by a superuser, but where sessions are multiplexed
over this physical pipe with the real user.
I can not seem to properly integrate this OCI connectionpool into weblogic.
When using this pool , and we are coming into a bean (session or entity bean)
weblogic is wrapping
this pool with it's own internal Datasource and giving me back a connection of
the superuser, but not one for the real user,
thus setting me with my back to the wall again.
I would appreciate if anyone had experienced the same problem to share a possible
solution with us
in order to satisfy all requirements(security,auditing,CMP).
Many Thanks

Hi Blyau,
As Joe has already provided some technical advice,
I'll try to say something on engineering process level.
While migrating an application from one technology to
other, like client-server to n-tier in you case, customers and
stakeholders want to push into the new system as many old
requirements as possible. This approach is AKA "we must
have ALL of the features of the old system". Mostly it happens
because they don't know what they want. Ad little understanding
of abilities of the new technology, and you will get a requirement
like the one you have in you hands.
I think "DBA must see real user" is one of those. For this
type of requirements it can make sense to try to drop it,
or to understand its nature and suggest alternatives. In this
particular case it can be a system that logs user names,
login and logout times.
Blind copying of old features into an incompatible new architecture
may endanger the whole project and can result in its failure.
Hope this helps.

How to take Input from the callers telephone keypad into oracle database

My client requires to automate a registration task for his customers by telephone. The requirement is the Oracle database should take numeric input from the callers telephone keypad eg 1 or 2 or 3 and the oracle must store this input inside its database and do some required processing with such input and generate a unique numeric id (sequence) and send back this unique numeric ID to the caller who is on hold. Please Note. Is there any electronic device to be installed at the client site to solve the above task eg. any telephone line to be connected to the CPU and etc?
I completely have zero knowledge. Please can you outline/summarise the instructions how to construct and install to meet my client requirement.
If this is not possible in Oracle I Can migrate to any database. Please suggest.
please help me. if you cant help i appretiate if you give me some clues

You need to start with your telephone system. Normally this situation would involve some sort of PBX or other internal switching equipment. Talk to your vendor. There's likely to be software, etc. available to perform the interaction with the end user.
It should have programmable "hooks" to interface with various databases. To Oracle it just looks like another program.

Not able to connect remote oracle database over VPN

I can not connect remote oracle database over VPN. tnsping is ok and it shows the server information of remote database. i can also telnet the 1521 port of remote database server. I can connect the same server when it is located in the same LAN. Please help me out this is very urgent.

First, this is a forum of volunteers. There is no "urgent" here.
"Urgent" means one of two things -
1) people are dying, or
2) you have a customer-facing, revenue-producing production system that is down.
(And to get some perspective on the second case, keep the first in mind.)
For the first, you call whatever civil emergency service seems appropriate.
For the second, you open an SR with Oracle - which requires a paid-up support contract. For *them* to consider your problem "urgent", you will need to demonstrate that your problem falls under item #2. I seriously doubt your problem fits that criteria.
You don't have a support contract? Now you know the exact dollar figure that your company places on the data.
That said, you need to understand a few things about your specific problem,
First, port 1521 is only used by the listener to accept a connection request. Once it gets that request (and finds that it is for a service (sid) that it knows about, it will fork a server process and tell the requesting client that it can communicate with that server process over some other port .. a randomly chosen port number in the "high" range. It could be your vpn is blocking that other port, whereas your internal firewall is not.
But this is just an educated guess since I cannot find "can not connect remote oracle database over VPN" in any error message manual. If you had mentioned the VPN along with an actual oracle error message we could be much more precise in our diagnoses and recommendations.
---- edit 22 Sep
It occurred to me that I just assumed you were using the same client machine in both cases ... a laptop that you use both at work (local network) and home (vpn). If that assumption is false, there are probably problems with your tns setup on the home (vpn) machine.
But again, it would be much easier to help if you gave us an actual error message.

Retrieve data from a synonym in oracle database through db connect

Hi Everyone,
I have created certain synonym for some tables in oracle. I want to retrieve data from it through db connect but where through source system and then selecting database tables, only tables and views are available.
Synonyms are not available to create data sources and retrieve the data from it. Why is it so. Is this a limitation of db connect.
Can anyone please let me know about it.
Thanks,
Joshua.

Hi,
You want to import data from an external Oracle database into your BW 3.X. To do this, you can connect the external database to the BW 3.X release as a source system using the external database connect. BW 3.X here represents BW 3.0, BW 3.1 and BW 3.5 because in other (DB relevant) parts, all 3 versions are based on the same source code.
General information
The above function allows you to load data from an external Oracle database (not a BW database) into your BW 3.0 system.
There may also be constellations which cannot be used directly through the DB Connect access. However, it should be possible to find an adequate, customer-specific solution for most of these scenarios.
In such situations, the resulting work falls into the area of Consulting and cannot be handled via Support.
Successful implementation of a connection requires corresponding expertise and experience in the use of the source database in the areas:
                - Tools
                - SQL syntax
                - DB-specific functions
Corresponding knowledge of the source application is also required to ensure that semantically relevant data arrives in the BW system.
Procedure
You should execute the following steps to connect the source system (Q) to the BW system (BW):
Installing the client software on an BW application server
                     Of course, you only need to install the client software if you are using BW with a non-Oracle database.
                     Use the Oracle setup program on the database CD (runInstaller on Unix) to start the OracleInstaller. Follow the program instructions and the DB installation instructions to install the Oracle Client software on BW.
Testing connection setup from BW to Q
                     After you install the client software on BW, try to set up a connection from BW to the server on Q. You may need to adjust the tnsnames.ora or sqlnet.ora files for this, to introduce the Oracle systems (to which contact should be made) to BW. You can test the connection by executing the command "tnsping QDB" on BW to check whether the client has established contact to the QDB database on the Q system.
Creating a separate U user in Q
                     We recommend that you create a separate U user in Q for connection to BW. This means that authorization and administration questions can be solved centrally.
Displaying data sources in Q for the U user
                     To provide U data for users other than U, you can create views on other user tables as user U:
                     CREATE OR REPLACE VIEW viewname AS
                       SELECT * FROM QDB.tablename
                     You may have to grant SELECT privileges to user U in the QDB schema:
                        GRANT select ON QDB.tablename TO U
                     Of course, you can also restrict or reformat data in the view arrangement (for example, change from internal date format into the SAP date format). JOIN operations using several tables are also available.
                     !!! Synonyms do not yet work!!!
                     Synonyms that you can create as described below are another option for providing a complete table for the user U:
                       CREATE SYNONYM synoname FOR QDB.tablename
                     !!! Synonyms do not (yet) work!!!
                     After you have displayed the require data for user U, you can simply use
                       SELECT * FROM <view or table>
                     on the Q system to check which data is returned.
                     You can now open a link to Q as user U in the BW system with SQLPLUS and check, using the same SELECT, whether this data is also seen in the Oracle client. If this is not the case, there is probably a connection problem.
Creating a connection from BW to Q in BW
Including data sources of user U user in Q in BW.
Solution
Supported BW, Basis and BW 3.0B database versions, Basis 6.20 Support Package 2 (or higher)
      Oracle 8.1 (or higher, see below)
Possible problems
- Synonyms do not (yet) work!
Up to now, only tables and views have been used as data sources for the DB Connect from the R3 Basis. As soon as synonyms are also used in the Basis, you will be able to convert created views (or even replicated tables) to synonyms as a workaround.
With Basis 6.40 at the earliest, therefore as of BW 3.5, you will also be able to use synonyms. Until then, the following will help:
CREATE VIEW <view_on_synonym> AS SELECT * FROM <synonym>
- The source DB must have at least the release version of the BW DB.
Oracle only ensures the support of client-server links if the version of the client is not higher than that of the server. So if BW has Oracle version 8.1 and, as in the case of Dbconnect, is run as a client against the server of the source database, the source database must have at least release Oracle 8.1 or higher.
Of course, you have the option to install the Oracle client software of a lower version and then use this for the DB connect. This is also the procedure used to work with a DB connect on external databases of other vendors.
Furthermore, the implementation of the DBconnect function in BW uses SAP Basis functions. Specifications of Oracle 8.1 database catalogs are used here. The source database must therefore have at least Version 8.1.
- Oracle Client Software Version
If you want to connect from an Oracle BW DB to an Oracle source DB, for the DB connect you naturally use the client software that you already installed on each application server.
If you want to connect from a non-Oracle BW DB to an Oracle source DB, check item 3 of note 521230 to see which Oracle client software version is released with your BW R3 kernel and use this version.
- Date and time fields in Oracle and their conversion into SAP-compatible column formats
Example with a DATE field:
Since a SAP table does not have a DATE field (date values are NUMC(8) and time specifications are NUMC(6)), we will use the Oracle DBA_TABLES system table as an example.
    SQL> desc dba_tables;
The Oracle DBA_TABLES system table has a LAST_ANALYZED field. This is a DATE type field and is recognized as a date field of 7 characters by DBA_CONNECT. However, the import does not work because the DATE is a 7-byte conglomerate of "...century, year, month, date, hour, minute and second." (extract from the Oracle documentation).
To make this DATE field legible for DB connect, you must use the TO_CHAR function in a VIEW. This should display the following examples:
SQL> select LAST_ANALYZED from dba_tables
      where table_name like 'RS%' and rownum < 10 ;
The formatting used here is the default used implicitly by SQLPLUS.
SQL> select to_char(LAST_ANALYZED,'YYYYMMDD') as dat from dba_tables where table_name like 'RS%' and rownum < 10 ;
The result now has the SAP compatible format YYYYMMDD and should be loaded correctly by the DB connect as a date.
SQL> select to_char(LAST_ANALYZED,'HH24MISS') as tim from dba_tables where table_name like 'RS%' and rownum < 10 ;
The result now has the SAP compatible format HHMMSS and should be loaded correctly by the DB connect as a time.
You can use the following example for more detailed experiments:
SQL> select to_char(
       TO_DATE('03-FEB-2001 04:05:06','DD-MON-YYYY HH24:MI:SS'),
       'YY-MM-DD HH24-MI-SS') as datim from dual;
with the result:
DATIM
01-02-03 04-05-06
When you create a VIEW and use the TO_CHAR function (or other functions), you should easily be able to avoid problems with the interpretation of date/time specifications (and other reformatting).
Details about the functions and the formats are contained in the Oracle documentation.
- Special characters
A words that contain special characters can only be imported correctly if the code pages in BW and in the source system are identical. If the code pages are not the same, DB Connect can be used if the characters to be imported appear under the first 127 characters of the character set.
The use of multibyte code pages in the source system for saving data using character sets with more than 256 characters (Kanji, Katakana, Hiragana, Korean, Chinese, Tagalog, Khmer, Arabic, Cherokee, and so on) can cause the characters to become corrupt.
For questions concerning the code pages, also refer to the FAQ note 606359 and question/answer 19 that appears there.

How to choose a right server for Oracle Database!

Hi all,
Is there any formular that allows me to find the appropriate server configuration for Oracle database 11g?
Please help!
Thank you all.
Dan.
Edited by: Dan on 01:45 06-01-2013

Simply put ... no.
Determining the correct server is a dance between hardware vendors (one point of input to be treated with general distrust), internal expertise and experience working with similar systems, and most importantly understanding the behaviour of what you are building.
Here are some sample questions to start the ball rolling.
1. What operating system expertise does your organization have?
2. What operating system expertise is readily available in the community from which you hire applicants?
3. What type of application?
4. What are up-time expectations?
5. Requirements for high availability?
6. Requirements for time to perform a full recovery?
7. Requirements for security?
8. Storage footprint (dictates internal storage versus SAN, NAS, or ZFS)
9. Anticipated growth (3-7 years)
Everyone wants to sell you CPU clock-ticks, more RAM, more IOPS, etc. But the first thing you need to understand is the capabilities you require that are generic: Required of any solution. Only when you have a clear understanding of these factors are you ready to discuss whether the solution is a pizza box or an ODA ... an Exadata or an IBM System Z.
Far too often I find people purchasing RAM they don't need with CPU speeds that exceed the ability of their network infrastructure to move the data so pay special attention when you are ready to make your purchase to engineered systems like the ODA.

Oracle database (10.2.0.4) and HTTP server / HTML DB conflict

Hi there,
I installed a fresh 10.2.0.1 (patched with 10.2.0.4) oracle database on Oracle Entreprise linux 5.7, and HTTP server + HTML DB products from the companion CD. Both are located in different home directory:
ODB: $ORACLE_BASE/product/10.2.0/db_1
APEX: $ORACLE_BASE/product/10.2.0/apex
I just discovered that logs files ($APEX/opmn/logs/) have filled up my entire disk this week end. After some googling / digging, I've read that there is a conflict between the ONS services that run for both products on the same port. Opening the configuration files of both products:
+$ODB/opnm/conf/ons.config+
+$APEX/opnm/conf/opnm.xml+ (btw, ons.conf is empty)
I indeed saw that they both use port 6113 as local port and 6200 as remote port. The workaround I've found in variuos places is to either change the port number, or unsuscribe ONS for the database listener (and sometimes both).
Question 1: what is the best solution ? what are the consequences for the database listener in case of unsuscribtion ?
I also saw that opnm.xml in APEX configuration file is making use of the $ORACLE_HOME environment variable, which I define in my /etc/profile as $ORACLE_BASE/product/10.2.0/db_1. So I guess the opnm of APEX is looking at the wrong place... Yet if I change ORACLE_HOME in my /etc/profile, I won't be able to run dbstart upon stgartup, as it is run using ORACLE_HOME in a init.d script...
Question 2: Can someone clarify things up about the exact relationship between oracle database and HTTP server ? How should I deal with ORACLE_HOME environment variable, which one use it and when... ?
Note that I'm completely new to Oracle (and hence APEX).
Thanks in advance!

There should be no conflicts - except for configuration ones.
Oracle is multi home capable. Thus multiple Oracle s/w products installed into different homes and these products running side by side.
The conflict is system resources - like a TCP port. That port cannot be shared by multiple processes. So you need to make sure that each s/w component that needs a TCP listener end-point, has a unique port number allocated for it to use.
As mentioned, the Oracle Apache server is an Oracle client with respect to Oracle client-server architecture. It simply needs a client OCI driver to connect to the Oracle database instance. So whether you run Oracle Apache on the same server as the database instance, or on another server all together - this makes no difference. The Oracle Apache s/w will be using its home for running. It has no need for anything from the database instance's home directory. Thus there are no conflicts - as long as you correctly keep them separated and not set the wrong home for the wrong component or include the wrong path (to another home's executables).
OK, so to summarize a bit:
- I should just be carefull when running startup script which will launch all services upon startup, i.e. changing the value of ORACLE_HOME before running each product startup script (dbstart => ORACLE_HOME = (..)/10.2.0/db_1, opmnctl => ORACLE_HOME = (..)/apex). I'm still quite worried because ORACLE_HOME is heavily used in opmn.xml but anyways.
- That's basically it: when each product's services are running, they do not use ORACLE_HOME (and such) anymore, hence no conflict from this point of view.
Also do not attempt to use IPC connectivity between the mod_plsql Apache module and the database instance. Does not make sense ito performance. Shared server should be considered and localhost TCP connectivity can be used.Well as I don't really know IPC yet, so hopefully I won't get into troubles. Just to be clear about that, i've this in my listener.ora:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /opt/oracle/app/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = apex.nwk)(PORT = 1521))
Does that mean that ICP will be used somehow ?
Thanks again from your help.

What I usually do in situations like this is that I connect to the database using a sql client and the same connection information as I specified to OIM and see if the attribute is present.
Perhaps you got the wrong db name? Or schema name?
Everything looks good so most probably there simply is some little typo somewhere.
Hope this helps

Using Coherence and Oracle Database as the CacheStore

We are working on implementing a solution using Coherence and Oracle Database as the CacheStore. We initially implemented the Cache as a distributed-scheme which in turn uses the backing-map-scheme. We are trying to introduce transaction management and I used a scheme-ref in a transactional-scheme to point to an already existing distributed-scheme. However when I bring up the server, my custom coherence-cache-config.xml file is not recognized and Coherence comes up with the default setting. Given below is the snippet of my configuration file.
1)     I would like to understand why the below configuration doesn’t work and am I doing it the right way? If not, what is the correct way of doing it?
2)     There are a multiple transaction management options given in the documentation. Which are the ones that will work with a distributed-scheme and read-write-backing-map-scheme?
3)     If transactional-schemes cannot work with distributed-scheme, what is the best way to have a distributed cache with a oracle database as a cache store?

Hi,
If you look at the documentation for transactional-scheme here: http://docs.oracle.com/cd/E24290_01/coh.371/e22837/appendix_cacheconfig.htm#BHCIABHA
you will see that it says The transactional-scheme element defines a transactional cache, which is a specialized distributed cache. That means that a transactional-scheme is already a distributed-scheme.
You will see from the same documentation above that there is no way in a transactional-scheme to configure things like cache-stores or listeners or even the backing-map-scheme as these are not supported on a transactional-scheme - so you cannot use a cache store.
Personally I would not use transactional-scheme unless you have some really big reason to do so - the restrictions far outweigh any perceived advantage of having a transaction. There are better ways to build applications so they do not require transactions, that is what we have been doing for years with Coherence so far, and there is no real reason to change that.

Performance Issues on Oracle Database Lite 10.3.0.3

Hello,
we have a big problem with one of our customers. He uses Oracle Database Lite in the standalone version. There are about 600 clients running a project with about 20 Publication Items. The customer works in the logistics field, so the Main time where nearly all clients want to sync and get their tours is from 02 AM to 05 AM, so that is the time with the most traffic.
Everything went well before last week. Suddenly the compose cycle needs (at least between that hours) about ten times longer than before. Normally we had about 40 - 80 seconds, now we have about 300 - 500 average with max values from over 1200 seconds.
Therefore we have a lot of conflicts and Disconnects on the clients. It is sometimes that bad, that nearly no client can sync successfully.
We checked our Selects in the publication Items, all are very fast and look good in the explain plan, so that shouldnt be the problem.
The installation is nearly in the Default state as oracle does when you install Oracle Lite. Are there any standard settings we can change? Does anyone had the same problem already?
The Machine is a Windows Server 2003 with an Intel Xeon CPU E7-4820 and 4 GB of RAM.
Of course our customer gets a lot of trouble because of that and we have to improve and fix that as fast as we can.
Any recommendation or opinions are very welcome.
If I have to give more Info about somewhat please feel free to ask, I will give it as fast as possible.
Thanks in advance
Holger

Hey,
many thanks for your proposals. The MGP runs every minute like the default settings are, because our application is a time sensitive. The data have to be very fast on the clients in the nights and thex are only a few minutes before available. I think the parameters are important in environemnts where the mgps runs only after a few minutes?
Let me summarize the situation since my las post:
We have days (nights) where everything goes quite well. Mainly that is thrusday and friday. But on the other hand, there are days where everything really is a mess.
The mgp caycles increase and when you look to mobile manager you see 70 clients syncing very very slowly (about 300 - 600 seconds) for just a little bit of data. Then we get the disonnects and the messages in the err.log.
What do you think, is this somehow network related, or ist this a logical problem in the Mobile Server itself?
Like postes earlier, there are 500 clients syncing against a standalone mobile server.
We just couldnt figure out, why the mgp times somehow and sometimes increase that much, that there are these problems.
First we thought, that they sync newly over wireless (GPRS or Edge) and that syncing is that slowly, that everything goes down, but arent sure. Is this possible because of the architecture of the Mobile Server? That a very slow network can slow down the mgps and that does timeouts and all the other stuff?
How many clients can a Standalone Mobile Server normally serve at same time without performance problems. What do you thin about the hardware I wrote? Is it powerful enough?
