RMAN backup to write on tape and disk in the same time

Hi all,
I want to take backup using RMAN and to have the backup file in a tape and a disk, i know i can allocate channel for tape, or disk. My question is can i use the both disk and tape in an rman backup one time. I mean i want to have rman writing backup file in a local disk and a tape in the same time to have redoundant backup at a tape and local disk.
If some scripts is there, it will be welcome.
Thanks

No.

Can I use the time capsule as backup and hard disk at the same time?

Hi.
I want to buy a time capsule.
I wondered, if I can use the time capsule as backup (over time machine) and as a hard disk at the same time?
If I buy the 2TB time capsule, I wanted to use 1TB for the backup and 1TB for hard disk.
Is this possible?
Best wishes

It is not recommended.. the problem being anything stored on the TC only is not backed up and cannot be backed up by the TC itself or Time Machine. So what are you going to do about back.. the TC can and do die suddenly.. and the cost of recovery can be huge.
See Q3 here for the semi-right way to do it if you must.
http://pondini.org/TM/Time_Capsule.html
You can plug a USB drive into the TC and use that for files.. but note, its speed is poor.. fine for wireless as wireless is even slower but you will really notice it if you expect the drive to be as fast as the internal.. it will be a fraction of the internal drive speed. 1/2 write and 1/3 read aprox.

Backup to file system and sbt_tape at the same time?

hello!
is it possible to do a rman backup to disk and sbt_tape at the same time (just one backup, not two)? the reason is, that i want to copy the rman backup files from the local file system via robocopy to another server (in a different building), so that i can use them for fast restores in the case of a crash.
if not, what is the recommended strategy in this case? backups should be available on tape AND the file system of a different machine.
environment: oracle 10g, windows server 2008, commvault for backup on tape
thanks for your advice.
best regards,
christian

If you manually copy backupsets out of the FRA to another location, but still accessible as "local disks", you can use the CATALOG command in RMAN to "catalog" the copies.
Thus, if you opy or move files from the FRA to /mybackups/MYDB, you would use
"CATALOG START WITH /mybackups/MYDB" or individually "CATALOG BACKUPPIECE /mybackups/MYDB/backuppiece_1" etc
Once you have moved or removed the backupsets out of the FRA, you must use
"CROSSCHECK BACKUP"
and
"DELETE EXPIRED BACKUP"
to update the RMAN repository. Else, Oracle will continue to "account" for disks pace consumed by the BackupPieces in V$FLASH_RECOVERY_AREA_USAGE and will soon "run out of space".
You would do the same for ArchiveLogs (CROSSCHECK ARCHIVELOG ALL; DELETE EXPIRED ARCHIVELOG ALL) if your ArchiveLogs go to the FRA as USE_DB_RECOVERY_FILE_DEST

Before I answer your questions, let me first just say thank you so much for your amazing patience and helpfulness. Whether or not we get to the bottom of this, I am very, very grateful to you.
We will get to the bottom of it, and you're quite welcome. Don't feel you ought to know all this stuff -- none of us were born with it!
By the way, in answer to your original question, yes, you can use the Time Capsule while backups are running. There's no conflict at all.
1) Estimated size of full backup: 205.94 GB
2) My LaCie has available: 11.04 GB of 359.95 GB
That's part of the problem right there; 360 GB is a bit small to back up 206 GB. Ordinarily, a Time Machine drive should be 2-3 times the size of the data it's backing-up, so Time Machine can keep a reasonable "depth" of old backups for you.
It looks like Time Machine is trying to do a fairly large backup, and there just isn't enough room for it.
But something doesn't quite add up. Time Machine should have deleted all but your most recent backup, trying to make room for the new one. But that would mean there should only be a bit less than 206 GB on the disk, not 360.
A clue may be lurking in your logs. Use the widget in #1 of Time Machine - Troubleshooting to display the backup messages from your logs. Locate the backup in question, then copy and post all the messages here.

Bulk load users into Directory and Messaging at the same time

Can I bulk load users into Directory and Messaging at the same
time?
<P>
Yes, but you are not really loading users into the Messaging
Server. The Directory Server contains all kinds of information about
users, including information about their email. So if you want to
load user information into the Directory Server, including the users'
messaging infromation, you must install the Directory server first.
Configure the directory server. Then install the Messaging Server.
Then you can load users into both by loading an LDIF file with the
user information.

Hi,
You can check the documentation: Multiple Copies of RMAN Backups ;-)
When backing up datafiles, archived redo log files, server parameter files and control files into backup pieces, RMAN can duplex the backup set, producing up to four identical copies of each backup piece in the backup set on different backup destinations with one BACKUP command. (Note that duplexing is not supported for backup operations that produce image copies.)
There are three ways to specify duplexing of backup sets when using the BACKUP command:
Specify a default level of duplexing with CONFIGURE... BACKUP COPIESAll backup commands that back up data into backup sets will be affected if you use this option, unless you specify different duplexing options for a command using SET BACKUP COPIES or provide a COPIES option for the BACKUP command.
Use SET BACKUP COPIES in a RUN block All commands in the RUN block will be affected, overriding any CONFIGURE... BACKUPCOPIES setting, except those where you provide a COPIES option as part of the BACKUP command.
Provide a COPIES option to the BACKUP command For this specific BACKUP command, files will be duplexed to produce the number of copies you specify.

Can we use both INSERT and UPDATE at the same time in JDBC Receiver

Hi All,
I would like to know is it possible to use both INSERT and UPDATE at the same time in one interface because I have a requirement in which I have to perform both the task.
user send the file which contains both new and old record and I need to save those in MS SQL database.
If the record exist then use UPDATE otherwise use INSERT.
I looked on sdn but didn't find any blog which perform both the things at the same time.
Interface Requirement
FILE -
> PI -
> JDBC(INSERT & UPDATE)
I am thinking to use JDBC Lookup but not sure if it good to use for bulk record.
Can somebody please suggest me something or send me the link of any blog or anything to solve this problem.
Thanks,

Hi ,
          If I have understood properly the scenario properly,you are not performing insert and update together. As you posted
"If the record exist then use UPDATE otherwise use INSERT."
Thus you are performing either an insert or an update which depends on outcome of a search if the records already exist in database or not. Obviously to search the tables you need " select * from ... where ...." query. If your query returns some results you proceed with update since this means there are some old records already in database. If your query returns no rows you proceed with "insert into tablename....." since there are no old records present in database.
Now perhaps the best method to do the searching, taking a decision to insert or update, and finally insert or update operation is to be done by a stored procedure in MS SQL database. A stored procedure is a subroutine available to applications accessing a relational database system. Here the application is PI server.   If you need further help on how to write and call stored procedure in MS SQL you can look into these links
http://www.daniweb.com/web-development/databases/ms-sql/threads/146829
http://www.sqlteam.com/article/stored-procedures-parameters-inserts-and-updates
[ This part you can ignore, Since its not sure that you will face this situation
    Still you might face some problems while your scenario runs. Lets consider this scenario, after the stored procedure searches the database it found no rows. Thus you proceed with an insert operation. If your database table is being accessed by multiple applications (or users) other than yours then it is very well possible that after the search operation completed with a null result, an insert/update operation has been performed by some other application with the same primary key. Now when you are trying to insert another row with same primary key you get an error message like "duplicate entry not possible for same primary key value". Thus you need to be careful in this respect. MS SQL has a feature called "exclusive locks ". Look into these links for more details on the subject

    There must be other methods to avoid this problem. But the point is you need to be sure that all access to database for insert/update operations are isolated.

IMac can't running any two fire wire hard disks at the same time . which

iMac can’t running any two fire wire hard disks at the same time . which two hard disks have extra power from power socket . If i just insert one of them .No problem . If connect two Hds at the same time. Leopard cant find it and the Hds seem no problem. the machine must be restarted and then use one . No problem . I have formated the HD many times .even if which format is Fat 32 or Mac issue persists .Boot from installation CD used the disk utility . Issue stills . If i used one fire wire HD that get power from power socket and used one fire wire device . Leopard was no problem during this time .

Reading and recording at the same time with AudioUnit

Hi,
I am trying to read and record at the same time on the iPhone with AudioUnit. For the reading part I made an AUGraph which works fine, constructed like that:
NewAUGraph(&_graph);
_outputUnitComponentDescription.componentType = kAudioUnitType_Output;
_outputUnitComponentDescription.componentSubType = kAudioUnitSubType_RemoteIO;
_outputUnitComponentDescription.componentManufacturer = kAudioUnitManufacturer_Apple;
_outputUnitComponentDescription.componentFlags = 0;
_outputUnitComponentDescription.componentFlagsMask = 0;
AUGraphAddNode(_graph, &_outputUnitComponentDescription, &_outputNode);
_mixerUnitComponentDescription.componentType = kAudioUnitType_Mixer;
_mixerUnitComponentDescription.componentSubType = kAudioUnitSubType_MultiChannelMixer;
_mixerUnitComponentDescription.componentManufacturer = kAudioUnitManufacturer_Apple;
_mixerUnitComponentDescription.componentFlags = 0;
_mixerUnitComponentDescription.componentFlagsMask = 0;
AUGraphAddNode(_graph, &_mixerUnitComponentDescription, &_mixerNode);
AUGraphConnectNodeInput(_graph, _mixerNode, 0, _outputNode, 0);
AUGraphOpen(_graph);
AUGraphNodeInfo(_graph, _outputNode, NULL, &_outputUnit);
AUGraphNodeInfo(_graph, _mixerNode, NULL, &_mixerUnit);
_generatorUnitComponentDescription.componentType = kAudioUnitType_MusicDevice;
_generatorUnitComponentDescription.componentSubType = kAudioUnitSubType_RemoteIO;
_generatorUnitComponentDescription.componentManufacturer = kAudioUnitManufacturer_Apple;
_generatorUnitComponentDescription.componentFlags = 0;
_generatorUnitComponentDescription.componentFlagsMask = 0;
for(int i=0; i< [_urlList count]; i++)
SoundBuffer* soundBufferTemp = [_bufferSoundList objectAtIndex:i];
AURenderCallbackStruct renderCallbackStruct;
renderCallbackStruct.inputProc = MyFileRenderCallback;
renderCallbackStruct.inputProcRefCon = soundBufferTemp;
AudioStreamBasicDescription* inputAsbd = [soundBufferTemp getASBD];
err = AudioUnitSetProperty(_mixerUnit,
kAudioUnitProperty_StreamFormat,
kAudioUnitScope_Input,
i,
inputAsbd,
sizeof(AudioStreamBasicDescription));
UInt32 zero = 0;
err = AudioUnitSetProperty(_mixerUnit,
kAudioOutputUnitProperty_EnableIO,
kAudioUnitScope_Input,
kInputBus,
&zero,
sizeof(zero));
err = AUGraphSetNodeInputCallback(_graph,
_mixerNode,
i,
&renderCallbackStruct);
This works well, for the recording AudioUnit I did the following:
OSStatus err;
AudioComponentDescription audioComponentDescription;
AudioComponent audioComponent;
audioComponentDescription.componentType = kAudioUnitType_Output;
audioComponentDescription.componentSubType = kAudioUnitSubType_RemoteIO;
audioComponentDescription.componentManufacturer = kAudioUnitManufacturer_Apple;
audioComponentDescription.componentFlags = 0;
audioComponentDescription.componentFlagsMask = 0;
audioComponent = AudioComponentFindNext(NULL, &audioComponentDescription);
err = AudioComponentInstanceNew(audioComponent, &_audioUnit);
UInt32 size;
size = sizeof(AudioStreamBasicDescription);
err = AudioUnitGetProperty(_audioUnit,
kAudioUnitProperty_StreamFormat,
kAudioUnitScope_Input,
1,
&_soundFileDataFormat,
&size);
_soundFileDataFormat.mSampleRate = 44100.00;
AudioUnitSetProperty(_audioUnit,
kAudioUnitProperty_StreamFormat,
kAudioUnitScope_Input,
kInputBus,
&_soundFileDataFormat,
size);
AudioUnitSetProperty(_audioUnit,
kAudioUnitProperty_StreamFormat,
kAudioUnitScope_Output,
kOutputBus,
&_soundFileDataFormat,
size);
AURenderCallbackStruct renderCallbackStruct;
renderCallbackStruct.inputProc = MyRecorderCallback;
renderCallbackStruct.inputProcRefCon = self;
UInt32 one = 1;
UInt32 zero = 0;
err = AudioUnitSetProperty(_audioUnit,
kAudioOutputUnitProperty_EnableIO,
kAudioUnitScope_Input,
kInputBus,
&one,
sizeof(one));
err = AudioUnitSetProperty(_audioUnit,
kAudioOutputUnitProperty_EnableIO,
kAudioUnitScope_Output,
kOutputBus,
&zero,
sizeof(zero));
err = AudioUnitSetProperty (_audioUnit,
kAudioOutputUnitProperty_SetInputCallback,
kAudioUnitScope_Global,
0,
&renderCallbackStruct,
sizeof(AURenderCallbackStruct));
err = AudioUnitInitialize(_audioUnit);
Then in I setup a file to write in:
- (void) openFile
OSStatus err;
err = ExtAudioFileCreateWithURL((CFURLRef) _soundFileUrl,
kAudioFileCAFType,
&_soundFileDataFormat,
NULL,
kAudioFileFlags_EraseFile,
&_extAudioFileRef);
err = ExtAudioFileSetProperty(_extAudioFileRef,
kExtAudioFileProperty_ClientDataFormat,
sizeof(AudioStreamBasicDescription),
&_soundFileDataFormat);
err = ExtAudioFileWriteAsync(_extAudioFileRef,
0,
NULL);
All this things works well (I check by printing err in the log which I removed here for clarity).
And then in the callback for recording I do the following:
static OSStatus MyRecorderCallback(void *inRefCon,
AudioUnitRenderActionFlags* inActionFlags,
const AudioTimeStamp* inTimeStamp,
UInt32 inBusNumber,
UInt32 inNumFrames,
AudioBufferList* ioData)
OSStatus err= noErr;
AudioUnitRecorder* auRec = (AudioUnitRecorder*) inRefCon;
[auRec allocateAudioBufferList:1 size:inNumFrames*4];
err = AudioUnitRender(auRec.audioUnit,
inActionFlags,
inTimeStamp,
inBusNumber,
inNumFrames,
auRec.audioBufferList);
err = ExtAudioFileWriteAsync(auRec.extAudioFileRef,
inNumFrames,
auRec.audioBufferList);
return err;
(Then I close the file after recording at the same time I close the AudioUnit)
Now the strange thing is that all this works perfectly well in the simulator: I can record and play at the same time but on the device, the callback for recording is not ran (I check by trying to print something in the log in the callback function.) which men no writing in the file and an empty file in the end.
Any one has any idea of what could be causing this?
Thanks
Alexandre

Just in case some one might need it, I solved my problem:
I simply needed to initialize the AudioSession before playing/recording. I did so with the following code:
OSStatus err;
AudioSessionInitialize(NULL, NULL, MyInterruptionListener, self);
UInt32 sessionCategory = kAudioSessionCategory_PlayAndRecord;
err = AudioSessionSetProperty (kAudioSessionProperty_AudioCategory,
sizeof (sessionCategory),
&sessionCategory);
AudioSessionSetActive(TRUE);

Can we use Badi BBP_SOURCING_BADI and BBP_DETERMINE_LOGSYS at the same time

Hi everyone,
We need you help. We are working in SRM 7 and ECC 6 EhP 4. We have a doubt. Can we use badis BBP_SOURCING_BADI and BBP_DETERMINE_LOGSYS at the same time in a classic scenario?
We want to create the contract in ECC, and then we want to return the SC in SoCo in order to create the PO with the SC and the contract.
We activate both, but the SC is not returned in SoCo.
Thanks,
Ivá

Hi Ivan
You can use both badi to change srm standard behavior.
but one shopping cart item and it can have only one follow on document either Contract or Purchase order.
i presumed that you want to use same sc for two purposes to create both SC and PO but it is not possible.
for example
shopping cart item has follow on document created as a contract But you need to create a another shopping cart to create a Purchase order w.r.t that contract .
Once follow on documents are created sourcing flag will be removed .- rule
BBP_SOURCING_BADI - you can write your custom logic and make way to cockpit .
BBP_DETERMINE_LOGSYS - Determine your logical system.

I've tried my apple ID password and that doesn't work either . I don't recall seting a password for an encrypted disk either :/ if it was for an encrypted disk, would it be in keychain anywhere? if so how can i find it?

Datasocket help, want to use the same(one .ocx only) in VB and HTML at the same time

I want to create one ActiveX control that can be use in VB and HTML. My control will consist 1 CommandButton, 1 TextBox and 1 Label.
My Objective is to have real time data passing between the same control which will be used at VB and HTML at the same time.
For example, from HTML if I click a button, the text at textbox at HTML will be pass to the label at VB at the same time. And vice versa where when button at VB is click, the text at textbox at VB will be pass to the label at HTML.
Help me.

Hello Sam R.,
The ActiveX will be written in VB6 with Measurement Studio6. It's some sort of tutorial lesson for me to test the capability of DataSocket.
I want to create 1 control which will act as reader and writer. I am using Windows XP with IIS as web server and testing using 1 open VB6 Form with the control and 1 HTML file with the control using Data Socket Server with dstp://localhost/something. I dont know whether I need to have the script or not, what ever can do. tell me if it is the way to do. If it can be program directly in the control is better.
Basically, yes. the command button inside the control should updates both label and textbox.
If you can say that 1 datasocket control is enough, I will follow your advice because you are the expert.
I try before by using the example in DSReader and DSWriter but I cannot do the 'real time' updating when I click either button in VB6 or HTML page. It can only updated when I click again the commandbutton and

IP over Firewire and ethernet at the same time?

Is it possible to use both IP over Firewire and ethernet at the same time?
I want to use my TB hard drive attached to one Mac via Firewire 800 to backup another Mac also attached to the same drive via Firewire 800. I can only mount the drive on one machine at a time so I need to share it out to the other Mac. It works great if I set it up to do strait IP over Firewire, with static IPs, but that means I can't connect to the internet because my ethernet connection on both machines becomes the secondary connection method. Similarly, if ethernet is primary then I can't connect via Firewire. Is there a way to set it up so the Macs will know which method to use depending on the IP address?
I am using 10.5.1 on both machines.
G5, 1.8 GHz, 15.GB RAM
MBP, 2.4 GHz, 4GB RAM
Thanks!

Certainly.
In the network control panel I set Built-in FireWire to the top of the service order list, followed by Built-in Ethernet.
Next, I set Built-in FireWire to Configure Manually with the address 192.168.1.xxx and the Subnet Mask to 255.255.255.xxx, making sure the Subnet Mask is set the same on both machines and that the IP address is different on both machines and different from the Built-in Ethernet addresses.
I applied the settings, turned on Sharing on both machines, then mounted whatever shared drives I needed by connecting to the other machine using the FireWire IP address.
Now I am able to share drives using FireWire 800 - which works great when used with Time Machine - and still use my normal ethernet to surf, etc..

Use one external harddrive on both pc and mac at the same time

i bought an iomega external harddrive today
can i use it on both mac and pc at the same times?
for ex:
when i plug in both computer
i could able to read and write on the hdd on both computer
since i format it into 4 partitions (2 journal and 2 doc)
so i wish i can use them separately in 2 computers

Hi Jerry_L and welocme to Discussions,
using such USB or Firewire connected external harddrives with two computers at the same time is usually not recommended by the manufacturer.
Doing so might lead to data-loss and the like.
Check with the manual of that harddisk to verify.
Using it with one computer at a time with your partitioning should be doable.
