Improvements to imp and exp utilities

Hello all:
Does 10g release 2 address the issue surrounding the inability for exp and/or imp to handle blob datatypes? We have a database the uses a couple of blob columns and each time (using Oracle 9i) I exp my tables and try to imp them, the blob columns are not created.

workaround is to create the table with the blob column first and then run the import with ignore=y.
to generate the blob table script use
imp file=<filename> indexfile=c:\temp\create_table.sql tables=<blob table>

Imp and Exp Command

Hi,
Pls explain me the concept of Imp/Exp command and the parameters assocoiated with it?If u can tell me online practicals for Import/Export command?
Regards
sudhir

At 8:03, you "wanna learn" about tablespaces and datafiles.
At 8:11 you want the concept of Imp/Exp explained to you.
At 8:10 you "wanna learn" the concept of Roll Back Segmenst [sic]
And at 8:12 you "wanna learn" all about SQL*Loader
Not bad for nine minutes of complete thoughtlessness, I suppose.
If you "wanna learn" all about Oracle, download the software, install it, start playing with it, and come back with some serious questions that show a modicum of thought, effort, persistence and care. Paying some attention to the usual rules of grammar and spelling might be an idea, too.
You'll find installations documented at http://www.dizwell.com/prod/node/695#installation, and then you can work your way through some concepts at http://www.dizwell.com/prod/node/263 and then you can start doing some basic fiddling at http://www.dizwell.com/prod/node/695#basics and once you've worked your way through that lot, you should be in a position to make sensible use of the stuff over at http://tahiti.oracle.com.
And after you've had a good read of the official Concepts book there, then you can come back here to ask specific questions and reasonably expect to get meaningful replies.

Imp and exp on diff version

hi
i have found problem in exp and imp in diff version of oracle
i have take exp in (Oracle8i Enterprise Edition Release 8.1.6.0.0) with no error
but when i imp this dmp on oracle personal edition
(8.1.5.0.0)
then it will gives error
is it possible to takes import data from higher to lower version.
thanks in advance.

Oracle does not allow to import data from higher version to lower version directly but you can do it if you take catexp.sql file from your older version and run that file in the Oracle Server where you have your higher version.
that file is found :
<ORACLE_HOME>/rdbms/admin
after you make the import you have to restablish your higher Oracle Server running catexp.sql beloged to that Oracle Server.

Hi everyone
I need you to test If the work I will do is right or not .
in general:-
I want to take full export from database 10g
and I want to import it in oracle database 7.3.2
in details:-
I will execute catexp7 on database 10g and after that I will take full export
and import the exported file on database 7.3.2.
If it is not right please could you correct me.
bye.

Running OMBPlus and EXP/IMP in mixed version environment

OWB Mixed Environment Guru's
Current environment:
OWB Client: 10.1.0.2.0 on Windows XP Professional
OWB Server side: 10.1.0.2.0 on UNIX (AIX 5.2)
Repository: Oracle 9.2.0.4 on UNIX (AIX 5.2)
UNIX Listener: 9.2.0.4 on UNIX (AIX 5.2)
Runtime Repository: Oracle 9.2.0.4 on UNIX (AIX 5.2)
I call this a mixed environment since my OWB stuff is 10g and my database stuff is 9.2.
Issues:
1- I can't get the command line exp.sh script to connect to the repository and returns the famous 'ORA-12154, TNS:listener does not currently know of service requested in connect descriptor'. It looks like the 'owbsetenv.sh' script is changing the value of $ORACLE_HOME to point to the 10g areas. Could that be then causing the system to look for a 10g LISTENER which doesn't exist since all my databases are 9.2.0.4???
2- I have the same issue trying to run OMBPlus.sh.
I am ultimately trying to set up a promotion process using the UNIX command line programs (exp/imp and OMBPlus) to get objects from the TEST environment into the PRODUCTION environment which is a separate repository and target schema on a different machine.
Any advice on how to successfully operate in this 'mixed' environment is most welcomed.
Many thanks!
Gary

Well it looks like I did it again!
Total brain fart.
The problem turned out that I wasn't specifying the entire SERVICE_NAME for the repository database. I had been leaving off the domain information. Must be a habit from not having to use it in the TNSNAMES.ORA files.
I was able to compelte my test export and connect to OMBPLUS and will now try my test import.
Sorry to clutter the forum but if it helps anyone else with the same affliction I seem to have frequently, I guess that's a small reward.
Until next time.
Gary

Export and Import Utilities

guys,
Does the import and export utilities come with the client install or do you have to install oracle database to be able to use import and export utilities.
Thanks

If you are using Windows the path to bin should something like below, it will be different depending upon the OS and directory structure you chose during Client installation.
In the DOS prompt(if in windows) go to the below directory and type exp help=y
C:\oracle\10.2.0\bin;
or see the path environment variable(MyComputer-->Advanced --> Environement Variables) is set to the above directory. If not set this variable.
In unix or linux you can export the above path variable or go to the $ORACLE_HOME/bin directory.
Eg:
C:\oracle\10.2.0\BIN>dir imp*
Volume in drive C is Local Disk
Volume Serial Number is 103F-E6B3
Directory of C:\oracle\10.2.0\BIN
08/29/2005 06:26p 212,992 imp.exe
08/29/2005 06:31p 114,688 impdp.exe
2 File(s) 327,680 bytes
0 Dir(s) 20,294,348,800 bytes free
C:\oracle\10.2.0\BIN>dir exp*
Volume in drive C is Local Disk
Volume Serial Number is 103F-E6B3
Directory of C:\oracle\10.2.0\BIN
08/29/2005 06:26p 471,040 exp.exe
08/29/2005 06:31p 114,688 expdp.exe

You can let Export prompt you for parameters by entering the EXP
command followed by your username/password:
Example: EXP SCOTT/TIGER
Or, you can control how Export runs by entering the EXP command followed

Expdb and impdb utilities

Hello,
I'm in an ORACLE 10g database, and trying to use the expdb and impdb utilities, but it keeps saying the command is not found. exp and imp work fine. My host system is LINUX. Does something else need to be set?
Rae

I believe that Oracle versions 10g and later provide both the orginal pair exp/imp, as well as the performance-enhancing *dp (DataPump) duo of expdp/impdp. The DataPump pair do not use the same syntax as the original export/import. As I recall, the dp enhancements are fairly ingenious, if you have time to read up on the dp tech notes.

Important!! Improve the life and performance of the battery.

Reduce the operating temperature and increase battery life
The battery in your notebook PC is designed to provide the necessary amount of energy for the processor while maintaining HP high safety standards. As a result, the battery may not charge or may stop providing power to the notebook when the battery temperature exceeds the specified, design safety level.
If the battery life appears shorter than normal, the battery stops charging before it is 99%-100% full and the battery appears warmer than usual, the battery has most likely reached its designed "no charge" safety state. The battery will no longer charge until the temperature condition is corrected.
Try one of the following methods to correct the battery temperature:
When charging the battery, do not use applications that require large amounts of system resources such as graphic or memory intensive applications, heavy and extended hard drive usage.
Turn off your notebook and remove the battery to allow it to return to a safe operating temperature.
Make sure the notebook PC is operating on a hard surface. Using the Notebook PC on a bed or sofa may block the vents causing the notebook PC to heat up and shut down.
By taking these steps, the battery will return to its normal operating temperature range and continue to charge and discharge as designed.
Calibrating the battery while PC not in use
Recalibrating the battery requires a cycle of a complete charge and a complete discharge. To recalibrate the battery while using the PC is not is use complete the following steps.
The recalibration may take 1-5 hours depending on the age of the battery and the configuration of the notebook PC you own. The PC should not be used while you perform the following steps. Completing all the following steps will also calibrate the battery so that the power meter readings are accurate.
Shut down the notebook PC
Connect the AC Adapter to the notebook PC and to an electrical socket.
Charge the Notebook PC until the Battery Charge light is Green. This indicates the battery is completely charged.
Press and release the Power Button to start the computer.
Press the F8 key several times when the HP Logo displays.
When the Windows Advanced Startup Menu displays, select the Startup in Safe Mode option.
Remove the AC power adapter from the notebook PC.
Allow the battery to discharge completely until the notebook PC turns off.
The battery is now calibrated and the battery level reading on the power meter is now accurate.
If you are not using the notebook regularly then please unplug the AC adapter and shut down the notebook. By following these practices will improve the life and performance of the battery. Here is a quick list of Do's and Don'ts for the care of your Li-On batteries:
Do's
When you receive a new Notebook or Tablet PC, leave the battery to fully charge overnight.
Condition a new battery by using it until it is fully discharged, and then re-charge it fully. Doing this once a month will help to accurately calibrate your battery.
Always ensure the battery is recharged as soon as possible after it becomes fully discharged. A battery will be permanently damaged if left for an extended length of time in a fully discharged state.
Remember that a Lithium-Ion battery will slowly deteriorate; a new battery will always perform better than one that is 6-months old.
Remember that the battery half-life is rated for a certain total number of charge/discharge cycles (see your User Manual or Quick Start Guide for the rating). For example, a battery that is rated for 3 hours and 500 charge/discharge cycles, will still be considered as within specification, even if it only lasts for 1 hour 45 minutes after 500 charge/discharge cycles.
Heat is the worst enemy of a battery. Allow plenty of air to circulate around the Notebook/Tablet PC, so that the battery is kept as cool as possible when charging and also when in use. If provided, use the integrated 'legs' under the Notebook to raise the notebook and improve air circulation.
Remove the battery if storing for several months (the battery should be at approximately 50% charge or higher).
If you use a NoteBus or if charging your Notebooks or Tablet PCs in a confined space, allow for adequate ventilation in order to keep the batteries as cool as possible.
Don'ts
Do Not - Expose the battery to excessive heat or cold (i.e. outside the range of 10-35 degrees Centigrade ambient).
Do Not - Store the battery in a fully charged state (store batteries with about 50% charge).
Do Not - Allow a nearly flat battery to be unused for more than a month or so. The battery will slowly discharge until it becomes fully discharged and this will permanently damage the battery cells.
Do Not - Charge your Notebook/Tablet PC inside a carry case - the battery may overheat.
Do Not - Charge your Notebook/Tablet PC when stacked on top of each other - the battery may overheat.
Remember: Your battery is slowly degrading all the time, even if it is not used. Keeping your battery as cool as possible will slow down this degradation considerably.

I have a WD Passport HD attached to my Mac. When it was last connected it went into sleep mode and ran out of battery. Now I cannot find my HD in Finder and Disk Utilities is telling me it cannot repair the HD. Any ideas on how to recover my data?

I have a WD Passport HD attached to my Mac. When it was last connected it went into sleep mode and ran out of battery. Now I cannot find my HD in Finder and Disk Utilities is telling me it cannot repair the HD. I can see the HD but the volume part is greyed out. Any ideas on how to recover my data?

There are other methodologies of scanning a HD
which involve data extraction, but loss of metadata is often the result if the directory is corrupt.
Metadata is the info on what the data IS.
Like having all your papers thrown in the air, its all there, but just a giant mess.
This is why you always always must have several external HD redundancies of your data. One isnt enough, neither is two really.
see here, and dont let that happen again>

Was that your only copy of your priceless data? Just that one external HD?

How to improve client handover and roaming between AP's

Improving client Handover and roaming between APs
There are a few standards and methodologies available to use to improve handover of clients between APs. Most are focused on VOIP technologies, but it must always be remembered that we cannot control the client Handover (especially with legacy clients) we can only encourage them. Some Standards and methods work well for some environments and some do not - test the recommendations extensively before implementing in a live Production environment. It must also be noted that all settings take effect immediately once applied, however from a client perspective it might need to re-associate for the changes to take effect client side.
As with everything else in IT, if a perfect method/solution existed there would only be one - try them all and keep the best.
The Standards and Definitions
802.11k
IEEE 802.11k allows a device to quickly identify nearby APs that are available for roaming. When the signal strength of the current AP weakens and the device needs to roam to a new AP, it will already know the best candidate AP with which to connect to.
802.11r
IEEE 802.11r specifies fast Basic Service Set (BSS) transitions between access points by redefining the security key negotiation protocol, allowing both the negotiation and requests for wireless resources to occur in parallel.
When a device roams from one AP to another on the same network, 802.11r streamlines the authentication process. BSS allows a devices to associate with APs more quickly. Coupled with 802.11k's ability to quickly identify the target AP, BSS's faster association method may enhance application performance.
Handoff Assist
The AP monitors the RSSI for every associated client. If the RSSI for a specific client falls below "low-rssi-threshold" and continues to fall for the "rssi-falloff-wait-time", then the AP will send a de-auth to the client.
The de-auth is meant to kick the client away from the current AP and get it to re-authenticate to a nearby AP. This will have the effect of helping a client handover between 2 APs.
BUT (Big But), if the client gets de-authed and takes a while to re-authenticate (if it even does re-authenticate automatically after a de-auth), then this will have the effect of destroying communication instead of helping it -- mostly found with legacy clients.
Remove Lower Transmit Rates
Removing lower transmit rates is a way to promote better roaming, BUT not all clients respond well, or even respond to it.
The practice is that the basic rates are a subset of the transmit rates. If you only want to allow speeds 9 and up, you would select only the transmit rates of 9 and up, and the basic rates of 9 and 11. If a legacy client expects the rates of 1 and 2 it will not connect.
Local Probe Threshold
Local probe Threshold prevents a client from connecting to an AP with a too low a signal - helps more with initial connection than roaming.
The local probe threshold parameter is not supposed to force clients to roam as soon as they pass near an access point with a good signal, but rather to NOT hold on to an access point with a weak signal (avoiding sticky clients).
PMK Caching
Defined by 802.11i and is a technique available for authentication between a single AP and a station. If a station has authenticated to an AP, roams away from that AP, and comes back, it does not need to perform a full authentication exchange. Only the 802.11i 4-way handshake is performed to establish transient encryption keys.
Opportunistic Key Caching (OKC)
Is a similar technique to PMK, but not defined by 802.11i, for authentication between multiple APs in a network where those APs are under common administrative control. An Aruba deployment with multiple APs under the control of a single controller is one such example. Using OKC, a station roaming to any AP in the network will not have to complete a full authentication exchange, but will instead just perform the 4-way handshake to establish transient encryption keys
Implementation and Configuration
802.11k
802.11k is configured in your VAP profile. Tick the option to “Advertise 802.11k”. There after set the Handover Trigger Feature Settings.
Tick the “Enable Handover Trigger feature” and then set RSSI threshold by specifying the -dBm level at what the hand over trigger should be sent to the client
802.11r
802.11r is configured under SSID of your VAP profile. Tick the option to “Advertise 802.11r”
HandofF Assist
Station Handoff Assist is enabled in RF Optimization under the RF Management section of AP configuration.
Tick the “Station Handoff Assist” option to enable it, next set the Low RSSI Threshold – the threshold determines above what level no deauth gets sent
Lower Transmit Rates
Transmit rates can be adjusted in the Advanced tab of SSID under your VAP profile.
Remember that the basic rates are a subset of the transmit rates. If you only want to allow speeds 9 and up, you would select only the transmit rates of 9 and up, and the basic rates of 9 and 11
Local Probe threshold
Local Probe threshold can be adjusted in the advanced tab of SSID under your VAP profile.
Depending on the density of your APs consider values between 20 and 40 -- 40 being aggressive in an AP dense area.
Deny Broadcast Probes
Denying Broadcast Probes can cause problems with Roaming especially if the SSID is hidden – leave option disabled.

Hi, thank you for the helpful guidance. I have a basic question, if the device roam from one AP to another AP with the same SSID. Is there a need of re-authentication given a) the network uses EAP based authentication; b) the network uses MAC address authentication. If there is no need of EAP re-authentication, how the 802.11 keys are moved to the new AP. Thank you very much if you could help me clarify my thought.

What happened to the Get/Set Date and Time utilities from RT 7.1?

I'd like to use the Get/Set Date and Time utilities that were available in 7.1, but disappeared after that. I see that the 7.1 utilites call a dll that does not appear to be installed with LabVIEW RT 8 and later. What do I need to do to use the utilites from 7.1 that do not appear in later versions?

In Labview 8.2 and later there are two directories for vi.lib. settime.dll is located in National instruments\Labview 8.2\Targets\NI\RT\ vi.lib
This is the dll you want to use in order to call it use the same Vi as in 7.1 (RT set date and time.vi) and link it to the correct dll.

Why exactly is a JSF IMP and a API, what is the difference?

Why exactly is a JSF IMP and a API, what is the difference?
I understand that JavaServer Faces technology is a framework for building user interfaces for web applications with a set of APIs for UI components and a custom tag library for expressing a JavaServer Faces interface within a JSP page.
But, why is there a jsf-impl.jar and a jsf-api.jar?
A clarification would be appreciated.
Thanks,

CowKing: Thank you.
In a discussion, when a developer refers to RI, they mean the jsf-api.jar only?
I don't need the jsf-impl.jar in my compile class path nor in my SJSAS 8.2 domain library directory either?
Thanks,
