Network speed for spatial oracle-Arcsde databases

Hi all
I am working in a oracle -ArcSDE production database environment. The data size is huge and more than 100 users are connected to the database. Wht should be the Reccomended Network speed for the database?
Thanks in Advance
Albin

Albin,
Obviously the faster the network, the quicker you will move data from the database to the client. However, in most cases (at least with a 1Gb network) I find that the neither the database or the network are usually the bottleneck with ArcMap, but instead the client-side "SDE"/rendering process. This is especially true when returning large numbers of geometries. The 10.x engine just chokes on anything more than a few thousand objects, and unfortunately the render model they use causes a full refresh on any movement / zoom, repeating the painful process over and over.
In a nutshell, it is simply a poorly designed architecture for today's loads. Our custom Java WebStart GIS client runs circles around it. Hopefully the new project they are working on will improve performance, especially when using native SDO_GEOMETRY data - but I haven't really had time to pound on it yet to verify that one way or another.

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?
We are not licensed for the Oracle Advanced Security Option and I have been tasked to use Oracle Network Data Encryption in order to encryption network traffic between Oracle instances that reside on remote servers. From what I have read and my prior understanding this is not possible without ASO. Can someone confirm or disprove my research, thanks.

Hi, Srini Chavali-Oracle
As for http://www.oracle.com/technetwork/database/options/advanced-security/advanced-security-ds-12c-1898873.pdf?ssSourceSiteId… ASO is mentioned as TDE and Redacting Sensitive Data to Display. Network encryption is excluded.
As for Network Encryption - Oracle FAQ (of course this is not Oracle official) "Since June 2013, Net Encryption is now licensed with Oracle Enterprise Edition and doesn't require Oracle Advanced Security Option." Could you clarify this? Thanks.

Enable hyperthreading for virtualized Oracle 11gR2 database (OEL57 64-bit)?

We are virtualizing our Oracle 11gR2 databases (running on OEL57 64-bit) on Vmware 5.1. I've read information at various locations that hyperthreading is not recommended for Oracle 11g database. One example is here, however, I seen many more:
http://bryangrenn.blogspot.com/2011/08/hyperthreading.html
My issue is that Vmware themselves recommends enabling hyperthreading for virtualized Oracle databases in their Oracle Databases on VMware Best Practices Guide.
Does anyone have any practical experience with this issue that can be shared? What are the advantages and disadvantages of enabling hyperthreading for our virtualized Oracle 11gR2 on OEL57 64-bit virtual machines
Thanks, Fred

If you read the comments on that blog you will see that the results are highly dependent on the type of CPU.
The effects can also be dependent on the nature of the workload: you may have CPUs that are fine with an OLTP workload, but don't scale as you might hope with a DW workload.

Minimum network speed for Fieldpoint

Which is officially the minimum network speed (in Kbit/s) required to communicate with a Fieldpoint? They can operate at 100 and 10 Mbit but that's an ideal maximum, i need to know the minimum recommended for proper working.
I need an estimate of required speed for reading/writing channels (i guess this depends on number and rate of channels), and for programming a RT fieldpoint with LabVIEW.
Thanks

Hi,
You can find all the useful informations about Update Rate of a FieldPoint Ethernet Network Controller at this link:
http://digital.ni.com/public.nsf/allkb/24FB518E1D24674686256DD7000C1EFA?OpenDocument
Regarding the minimum possible speed network to comunicate to FP, it's depends on timeout parameter you set in the target: obviously a low-speed network could generate some comunication problems.

JDBC API ( JSR 169 ) Implementation for accessing oracle lite database

We are developing an application using IBM J9 (CDC and Foundation Profile) on Pocket PC 2003 environment with SWT as the front end development. We are using Oracle Lite 9i as the Client database.
We have sucessfully installed Oracle Lite and was able to create tables in the database.. however we could not find the JDBC API (java.sql and javax.sql packages which is JSR 169 JDBC 2.0/3.0) inorder to load the JDBC driver(OLITE40.jar) and access the oracle Lite Database on Pocket PC.
IBM J9 Micro Environement does not have this support.
I am wondering if Oracle provides this implementation.
If not is there a get around.
the client database is crucial to the application and i would really appreciate an answer to our problem.

Opening OEM for two Oracle 11gR2 Databases in the same web browser automatically log out.

Hi to everyone,
I have an issue regarding Oracle Enterprise Manager in 11gR2. I have two database (SWPROD, PDPROD) in a single server. When I open the OEM URL for SWPROD it is successfully logged on but when I open the OEM URL for PDPROD and successfully logged on the other tab for SWPROD will automatically logged out. And when I switch to the other tab for PDPROD it is also automatically logged out. Both OEM URL is open in a single web browser like Mozilla Firefox. What would be the reason why both OEM URL will be logged out when I open them at the same time?
Thank you for your incoming response.

Well it seems the only way to clear these out of EM was to shut BOTH RAC nodes down and power them up one at a time. Now the updates aren't shown as required and my compliance score is where it should be.
Is this a bug ? Seems pretty stupid to have to shut down both RAC nodes to fix this. Powering a single RAC node off and back on did not clear this.
Unless i'm missing something??

Factors for increase in memory occupied by Oracle 11g database

I wanted to know all the possible factors which can account for the increase in the memory required for an Oracle 11g database. Let’s take an example,
1) Say if the memory allocated for an Oracle 11g instance is 8GB which is 50% of the memory of 16GB allocated to the machine on which Oracle 11g is installed.
2) The max sessions are 300.
With this example in mind, I had the following queries:
1) Is the memory taken by 100 sessions or 300 sessions going to be within the limit of 8GB allocated to the Oracle?
2) Say if the max sessions is increased to 400, would the memory taken the 100 extra sessions would be within 8GB or would that be extra?
I hope my query is clear.
Please revert with the reply to my query.
Regards

Memory is allocated for the session only when that session is created by the listener, and the memory used by that session will fluctuate depending on the workload it's doing.
300 or 400 it won't pre-allocate all the memory for the fixed maximum number of sessions, it's dynamic. What oracle does is allocated all the memory you gave it in the PGA and the SGA and will do it's best to work with it for the current workload, it won't suddenly eat more memory without you telling it's okay to.
The only scenario I could see this happening is if you have a lot of sessions and a small PGA. In that case, oracle does go ahead and eat more memory than you gave it because it can't make due with the current PGA. So it eats more memory so sessions can be created and maintened. See PGA over- allocation.
To quote the good ol' docs:
Over allocating PGA memory can happen if the value ofPGA_AGGREGATE_TARGET is too small. When this happens, the Oracle Database cannot honor the value ofPGA_AGGREGATE_TARGET and extra PGA memory needs to be allocated.

Oracle 9i Database -- Performance window in Grid Control not data available

Hi
I have Grid Control 10.2.0.4 on Red Hat and i monitoring some Oracle 9i Instances. When i go to any of these instances to the Performance section, at begininig , ever, not data available in all the graphics.
When i select manual refresh the graphic begin to build information. But if i close the explorer and reopen , all graphics not have any information.
Is the situation normal for all Oracle 9i databases?
The explanation is that Oracle 9i not have AWR ?
Thanks

You have too few RAM on your machine, even you could successfully create an instance, it's going to slow as hell.
When you run DBCA to create database, instead of actually creating the database you could choose to dump the SQL scripts and files used for database creation to a directory. This way will give you a chance to modify pfile and reduce the SGA parameter. I believe the default SGA of instance created by DBCA is already beyond your RAM limit.

Migrate Oracle 9i Database to Oracle 10g Solaris Platform

Hi DBAs,
Thank you very much all of you, you helped me in RMAN Duplicate Database, There was a problem in my backupset and now it has been resolved.
I have now following task.
I want to migrate Oracle 9i Database to Oracle 10g ASM, both are on Solaris platform. Please provide me step by step solution. I have very big Database about 250G Database.

In the "Complete checklist for manual upgrades to 10gR2" is written:
PREREQUISITES
=============
+ Install Oracle 10g Release 2 in a new Oracle Home.
+ Install the latest available patchset from Metalink.
+ Install the latest available Critical Patch Update.
... so "Install the latest available Critical Patch Update" step is that for the Oracle 10g database Oracle Home or Oracle 9i database Oracle Home ? I think that is for the 10g database/ Oracle Home ...
after applying the CPU pacht there is some "Post Installation Instructions":
3.3.5 Post Installation Instructions which demande a connection to the database:
3. For each database instance running out of the ORACLE_HOME being patched, connect to the database using SQL*Plus as SYSDBA and run catcpu.sql as follows:
cd %ORACLE_HOME%\CPU\CPUJan2007
sqlplus /nolog SQL> CONNECT / AS SYSDBA
SQL> STARTUP
SQL> @catcpu.sql
SQL> QUIT
My question is ... If I want to upgrade a 9i database to 10g and I apply this CPU before the upgrade is done (to 10g Oracle Home), how could I connect to an instance which is not present to run this script ? ... is this step mandatory or is optional ?
Thanks,
P.

Error in Oracle Lite Database connection

Hi,
I have installed the Oracle Application server 10.1.3.1.0 on my laptop (basic installation).
I tried to define a database connection in the JDeveloper connection navigator to the Oracle lite database. When I test the connection I got an error:
"Internal Error:Invalid Connect String".
I have defined in the connection tab of the Edit database connection in the following way:
Driver class: oracle.lite.poljdbc.POLJDBCDriver
Library: OLite
Classpath: C:\product\10.1.3.1\OracleAS_1\bpel\lib\olite40.jar
URL: jdbc:polite4@localhost:100:orabpel
Could anyone tell me which user and password I should define for the oracle lite database which is delivered with Oracle Application server 10.1.3.1.0?

Hi,
Did you start the SOA suite on your workstation?
If so, can you reach the BPEL Console
if so, check via Enterprise Manager the connect string in the OC4J instance of BPEL (oc4j_soa -> administartion -> JDBC > conenctions, or data-sources.xml)
Copy the connect string into your OLite config if it works
