Requests deployment architecture Oracle Timesten Geo-redundent

Hello

We have 6 sites and each site to connect with the line of lease.

There are 5 different physical Remote Site, we want to deploy the database to the active / standby timesten on 5 sites
We want to create READ ONLY CACHE LOCAL GROUP for each 5 Sites which is unique site automatic updating (2 node RAC) Central database
Data changes always happen on the Central Site.

Oracle timesten active / standby is LAN on each site, but each site is connected via WAN to the Local Central site where the Oracle RAC database
and configure the Cache to connect each site for Auto refresh read only Cache and a Local Group on each site.

OVERVIEW OF THE ARCHITECTURE

Remote Site location-1 == > (read cache only Local Group) Oracle TT c/o < < = auto-refresh <-|
||
Location of Site remote-2 == > (read cache only Local Group) Oracle TT c/o < < = auto-refresh <-| (CENTRAL LOCATION)
||
Remote Site location-3 == > (read cache only Local Group) Oracle TT c/o < < = auto-refresh <-| (Database RAC 2 knots)
||
Remote Site location-4 == > (read cache only Local Group) Oracle TT c/o < < = auto-refresh <-|
||
Remote Site location-5 == > (read cache only Local Group) Oracle TT c/o < < = auto-refresh <-|

We pass below Oracle technical document.
http://www.Oracle.com/technetwork/database/performance/WP-IMDB-cache-130299.PDF
Please check the Figure 7 == > differentials Autorefresh of Read - Only Cache of local groups

Please suggest your advice and your suggestion for above deployment architecture

There are many things that you must understand and keep in mind when implementing a complex system, and it is oexception n. You should start by studying documentation TimesTen. In particular you should familiarize yourself with the information in the Cache User Guide and the Guide of the replication. These contain a lot of very important information regarding the installation/deployment and operation c/o pairs and groups of cache, configuration cache link for CARS etc. You should also read through the troubleshooting guide to familiarize yourself with what things to look if things do not seem to work as expected.

If you are not already familiar with TimesTen, I would also highly recommend that you take the time to read the rest of the documentation. TimesTen is not Oracle Db and it is very compatible with Oracle in many areas, there are also many significant differences you need to consider when developing applications, management of the etc system, if you are able to take a training course OR on Timesten then I would recommend but if not then read the documentation is a good second best.

It is "not recommended" operating systems specifically, but 64-bit Linux is definitely a good choice. You might consider Oracle Enterprise Linux instead of Redhat; It has some advantages.

In each site, the two nodes in the pair of active / standby TimesTen should be on the same local network. I would recommend GigaBit ethernet as a minimum.

Although it is possible to write your own scripts much easier (and much more robust) handful of deployment, monitoring, failover and recovery of pairs a/s there a lot, if you deploy Oracle Clusterware on each site for automated management of the pairs a/s. It is our strong recommendation and is also recommended.

From a point of view TimesTen, system clock synchronization is necessary within each site (i.e., the clocks on both nodes in a system have? Pair of S must be closely aligned). However, it may be desirable to have all nodes in all sites have their clocks in line for other reasons.

You must ensure that the bandwidth and latency of the WAN connections is sufficient for the amount of traffic to refresh you. There is no simple way to estimate/calculate this. you will need to determine empirically.

These are probably the most important things. As you progress, you can of course ask questions in this forum and use Oracle.

Hitgon
My response was only assuming that Oracle on a single primary site. Architecture that I'm saying is:

Location1-Remote Application<----Read only-------timesten1="" |=""><------TimesTen>

Guest place.2-Remote Application<----Read only-------timesten2="" |=""><------TimesTen>

Location3-Remote Application<----Read only-------timesten3="" |=""><------TimesTen replication--------|=""><-----TimesTen a/s="" pair=""><--- autorefresh=""><----- |="" oracle="">
(2 machines)
Remote Application Location4<----Read only-------timesten4="" |=""><------TimesTen>

Location5-Remote Application<----Read only-------timesten5="" |=""><------TimesTen>

It's far the best architecture for performance, resilience, etc..

If the volume/rate of change of data that need to be updated for caches is very low then you might consider this architecture but it will impose a load more on the Oracle DB.

Location1-Remote Application<----Read only-------timesten1="" |=""><---------------Auto refresh------timesten="" cache="" connect="">

What types of services offers group TimesTen pre-sales, is he coordinated it please?

Thank you, good luck.
Hi 965670,

Consultants pre-sales Oracle work with sales team, so I think you should include sales person in this project. I know because I worked for Oracle. :), but in any case you can contact directly with the technical adviser.

On further analysis, it is really depends on consultant's qualification and knowledge. When I worked for Oracle CIS, I did this kind of expertise (analysis of applications and architecture, POC and etc..). I think there are many people who can do in US. Please contact the local office of the Oracle and ask them.

Limitation of Oracle Timesten database

Hello

We want to deploy the Timesten11.2 Oracle on RHEL 64-bit platform.

The total physical RAM size in server is 32 GB.

There are 40 million lines of single Subscriber table (45 columns) in the Oracle database
We want to configure the CACHE of READ-ONLY-LOCAL in Oracle Timesten for this table to the Subscriber.

What should be the size of Oracle Timesten support the above configuration database.

Hi hitgon,

You can use the utility ttSize (http://docs.oracle.com/cd/E21901_01/doc/timesten.1122/e21643/util.htm#CHDEHFIE) for the prediction of the size.

Example: ttSize - tbl tableName-lines 40000000 your_DSN

In addition, you can use ttComputeTabSizes function and tableGroesse clause to get the actual table size

Command> call ttComputeTabSizes('emp');
Command> tablesize emp;

Sizes of GENA.EMP:

  INLINE_ALLOC_BYTES:   0
  NUM_USED_ROWS:        0

Architecture Oracle query

Hi all
I was reading about architecture oracle docs and
I was confused that if oracle database receives a Sql statement, then he gets first in what part of the LMS? Area DBBC or SQL shared (in the Shared pool).
Thanks in advance

If you want to understand the process, you need to actually READ this doc of Concepts - not just look at the pictures.

1. even the output of select statements gets written in Database Buffer and Redo Log Buffer, respectively.

NO! -Read this doc and learn the purpose of the buffer cache and the redo logs. Why a select statement would cause data is written in the REDO logs if there was no change to the data?

2 and when a DDL / DML statements is executed, first exit-East block written to redo log buffer and then he gets to the data buffer.

NO! -Read this doc and learn the purpose of the buffer cache and the redo logs. If the data did not change why it would be written to the REDO log?

http://docs.Oracle.com/CD/E11882_01/server.112/e40540/physical.htm#sthref1447

Structure of the online Redo Log

Online redo logs contain records of roll forward. A redo record is composed of a group of agents of change, which describes a change to a data block. For example, an update to a salary in the employees table generates a redo record that describes the changes on the block of the data segment of the table, the data of the undo segment block and the table transactions undo segments.

Do you think ANY reference to a select in there?

Read the section above.

Architecture Oracle book
Hi DBAs,
Oracle version: 10 g
OS: Windows / Linux

Please suggest me book Architecture Oracle and concepts.
I want to understand oracle architecture and basic concepts of each theme.
I have basic/initial understanding of concepts and architecture, but I want to make my clear understanding with knowledge.

Thank you
You've already got great suggestions in the first answer, of Centinul.

What you're looking for?

If you have not already during the studies of the OCA, be sure to read Concepts guide/book of end-to-end a couple of times.

As you get more comfortable, refer to the guide of the Admin, reference manuals, etc. in the section "Support the Documentaion" for more details. Concepts guide of course includes links to relevant and specific topics in other books in the library of documents.

In addition, it can help learning (and remembering) If you have a lab nearby, database server so that you can practice stuff alongside read on this subject.

Edit:
Response was for last message to the op above.

Deployment of Oracle 11g RAC Release 2 with IBM midsize V7000

Oracle Grid these days use ASM starts for vote and register files storage. So no need for a cooked cluster file system that must be mounted by all nodes. No need either directly with a gross storage logical unit number.

ASM uses the LUN of the matrix of storage/SAN directly (as devices of rough blocks).

Generally however, there are several I/O paths to that LUN on the SAN - in which case there is more than 1 device level o/s for this LUN. Multipath driver s/w addresses this and creates a logical (and redundant) device that sits at the top of several devices of i/o path to the level of the o/s.

You configure ASM to use devices of paths multiples (as devices of rough blocks) - and applying exterrnal, normal or high redundancy necessary when creating starts on these logical multipath devices.

The grid s/w and RAC database instances can then use ASM starts as cluster storage.

This makes storage much easier layer management - and also provide a number of useful features too.

This is also the approach recommended by Oracle Corp. for RAC - use ASM under the layer of management of storage between storage LUNS in the table and one side and CARS on the other.

The OAM Console in a deployment architecture high availability

Hello
I'm looking to implement a HA for OAM environment and read the various docs that the OAM console is deployed on the AdminServer. However, when I read the Oracle documentation on Oracle Fusion Middleware high availability Guide for Oracle Identity and Access Management
It gives the URL in the console of the OAM as the link to test the server managed, which means that OAMConsole is accessible on the ManagedServer. Is there anywhere I can find a definitive answer on how OAMConsole is deployed and in the what server / cluster?
Ideally, I'd like the OAMConsole app deployed to the cluster (instead of the AdminServer) in order to achieve for her AP.
Thank you

oamconsole is deployed on the AdminServer, and there may be only one admin server active per domain.

The link that you are referring is on setting up a cluster OAM. Oracle encourages a cluster OAM of 2 instances that are deployed on 2 physical servers. The server administrator is recommended to set up an alias to separate host that they refer as a VIP that is linked to a separate IP as the OAM instance on the same host address. A clone of the Admin instance is then placed on the second physical server corresponding to the second instance OAM. In the case of the first instance OAM and the server administrator is not available, a reconfiguration of network must be made to move the VIP to the second instance. Once this is done, the server administrator can be started on the second server.

This gives you a little HA/DR.

11.1.0.7.0 customer database is supported for Oracle 10 g 2, databases Oracle 11 GR 1 material and 11.2.0.2.0 for Oracle 11 GR 2 (required only for Oracle databases and supports only the 32-bit version).
Any comment is appreciated.
Best,

It depends on P6 web or client P6...

In any case one thing you should know is customer P6 technology old enough to connect to Oracle database are supported only by the 32-bit Oracle client. This means in the db server, is not of importance by using 32-bit or 64-bit, but in the side (PC) client that must be 32-bit installed Oracle client to connect to Oracle database.

But if you want to use only P6 on the web, it should not be a problem.

I hope this will help

Hello

You can install the database using a response file. Depending on the setup of your Java application, you can create a sort of meta-Installer creates a response file for the database and a response/parameter file for your application setup program and then run both in a single step.

Independent error after processes deployed in Oracle BPM company
Hi all.

After you deploy my standalone Oracle BPM business process. Almost everything is ok. But my global activity: Global auto generated the error below:

\#default-1.0GlobalAutomatic' (BP-method GlobalAutomatic). Details: the method "CIL_globalAutomatic" of class "oracle. CadastroContratos.Default_1_0.Instance' cannot be run successfully. Caused by: creating a different engine instance not supported

Someone knows how to fix this?
Hello

If you get the error "creating instances of different engine not supported", you might want to double check the logic of your Global Auto when you create the instance. If you have a typing error in the first parameter of the method of Instance.create (), I guess you can get this error.

1. right mouse click on the process in the project browser that you want to create the instance from your logic-> properties-> note the process id in the only area to read.
2 use this chain process id in the first parameter and prefix character ' \ '.
```
Instance.create (processId : "\SomeProcessName", arguments : args, argumentsSetName : "BeginIn")
```
If you create an instance in the same process, where the overall auto, rather use the logic:
```
Instance.create (arguments : args, argumentsSetName : "BeginIn")
```
Hope this helps,
Dan
