How to Create Virtual Tape Library for RHEL 5.4

Hi,
We are planning to use a tape library (well, as our team proposed) so we are trying to create a Virtual Tape Library as a proof of concept on this project. Can you help us create virtual tape libraries using raw devices.
We will be using Virtual Box as our virtualization environment which will run RHEL 5.4. Will this be possible?
Thanks and hope you can give us some ideas.

I tried the exact same setup and it is possible. What you will need is mhvtl and Oracle OSB to get a Oracle Media Management Library (MML).
Please see Integration of RMAN with virtual tape library
The link above should provide the setup info you will need. There were some initial problems, but according to follow up posts later versions of the products seem to have fixed the issues with tape handling.

How to create a new library for my wife's iPod

Hi all,
I've been trying to get the right answer to this for a long time, but I seem to be continually coming up against very complicated solutions that are too intricate for me to actually try. I hope someone will have the knowledge (and the patience with me!) to help.
My wife received an iPod as a gift from the Mayor of San Francisco. It came pre-loaded with a bunch of songs about "The City by the Bay." It's a Nano, so it doesn't have iOS 5, the iCloud, etc.
So I have two questions.
(1) I have my own iPod, iTunes account, and my own laptop. My wife only has a work laptop so she can't load iTunes onto it (which would make this very simple).
(2) I would like to be able to create a situation in which:
(a) She can create her own library on my computer. Her library would include a lot of music from my library (but not all). In other words, I want to move some music from my library to her library, both of which are on my laptop.
(b) She can sync her iPod on my computer.
(c) She can load all the San Francisco music into "her" library.
Is there a simple way to do this? I don't want to do the "separate playlists" variation because that's not how I want to run my own library. I want that to remain as crisp and clean as possible.
In short, probably creating a new User account on my MacBook Pro, is there a way that I can "give" her a few dozens of my LPs, but then have pretty separate syncing experiences? As I say, I've read a million different treatments of this, and they all seem more complicated than I'm ready to do.
Thank you!!!!

Or could I just plug her iPod into my computer and "manually manage music"? What if it's somehow already set to "automatically sync"? She would lose the music that's already on her iPod, wouldn't she?

How do I duplicate the exact playlists from my iphone 4th gen to my new ipod 4th gen 64gb? So far I've created a new library for it, duplicated all the apps, books

I'v been using an iphone 4 (16gb) for a year now, and have just got an ipod touch 4gen, 64gb. I created a new library for this, and most of what I have managed to transfer everything onto the ipod touch. However, although all my music has transferred, the playlists have not. Do I have to transfer them manually? That is, creating every playlist again, which would be a nuisance since I have 48 playlists and almost 250 pieces. All the music have been bought from itunes.
What I plan to use the ipod for is mainly for books, magazines and itunes U podcasts. Most other apps and music will be the same on both iphone and ipod. Both are under my same apple id. Please help, 'cos I've been searching for an answer on the internet and can't really find one. Everything else has transferred expect the playlists.

- Go to settings>Store and sign out and sign into your account.
- Apps are locked to the account that purchased them.
- To update apps you have to sign into the account that purchased the apps. If you have apps that need updating purchased from more than one account you have to update them one at a time until the remaining apps were purchased from one account.

Integration of RMAN with virtual tape library

OS: Oracle Linux 5.5 UEK (Virtualbox)
Oracle: 11gR2 11.2.0.1 Enterprise + ASM (Virtualbox)
Hello,
I would like to test something about RMAN and writing directly to tape. For this I installed mhvtl, a virtual tape library. The installation was pretty easy. http://sites.google.com/site/linuxvtl2/
RMAN does not recognize any tape in the system.
ORA-19554: error allocating device, device type: SBT_TAPE, device name:
ORA-27211: Failed to load Media Management Library
What I found out is that in order to make backups to a media manager, RMAN must communicate with a media management library, which is a 3rd party library that is not supplied by Oracle. So I guess unless there is a Oracle MML library available for mtx I' out of luck here.
Any ideas? Thanks!
rpm -ivh mhvtl-0.18-13.x86_64.rpm
rpm -ivh mhvtl-0.18-13.src.rpm
cd /usr/src/redhat/SOURCES/
tar zxvf ../SOURCES/mhvtl-2011-01-11.tgz
cd mhvtl-0.18/kernel
make
make install
/etc/init.d/mhvtl start
yum install mtx
The tape library and using it for backup from system seems to work fine:
# mtx status
Storage Changer /dev/changer:4 Drives, 43 Slots ( 4 Import/Export )
Data Transfer Element 0:Full (Storage Element 1 Loaded):VolumeTag = E03001L4
etc.
# mtx load 1
Drive 0 Full (Storage Element 1 loaded)
# tar cf /dev/ntape ./
# tar tvf /dev/ntape

Thanks for the tip!
I installed Oracle Secure Backup Express and spend all afternoon with this strange product, mainly to troubleshoot the installation and setup. I'm not really sure everything works - it's quite a piece of software, as usual.
I ran into a couple of issues that were not mentioned in the installation documentation:
- install sg3_utils
- use obtool to register the server as mediaserver

RMAN was not happy with it:

Document ID 396046.1 solution outlines to correct the hostname or mediaserver name. However, this was not the problem. I finally figured that /etc/obproxyd is a symlink to a .wrapper script which points to the actual proxy application. The fix was:
#chmod +s /usr/local/oracle/backup/.etc.linux86_64obproxyd
After this the error changed:

Strange, backup to tape with 'mtx' and 'tar' works, so the problem might be OSB.

I finally got it running. I deleted the current library and drive configuration and used the webtool to configure the other library at /dev/sg17. it was also necessary to use the webtool to load a volume into the drive. Unfortunately I did not note down the steps in details. Maybe next time.

OSB with a (non-supported) virtual tape library

For testing and learning purposes, I have installed OSB 10.3 and the virtual tape management system mhvtl (http://mhvtl-linux-virtual-tape-library-community-forums.966029.n3.nabble.com/MHVTL-Linux-Virtual-Tape-Library-Getting-Started-td1663811.html). It seems to work quite well apart from one serious shortcoming. If a virtual tape which is already labeled and used as part of a media family is unmounted from the drive, a subsequent re-mount leads to a relabel of the volume whereupon all pieces and any reference to the volume are lost. If the virtual tape is left in the drive, there is no issue - new backups are appended to the end of the volume as one would expect.
Somewhat perversely, when I mount a used tape, OSB correctly identifies it. As soon as I start writing to it though, the volume is re-labeled.
I can overcome the issue by using obtar -z to advance the tape to the end of the volume.

At this point, any new backup starts writing to the virtual tape at the current position, and existing files on the volume are preserved - no re-label is carried out.
I'd like to debug OSB but when I try to set up debugging on the volume, I get:
$ obtool labelvol obtaropt J drive VDAT72

If anyone has some clues, I would be grateful.

I created a 2nd library for my husbands music and now I can't find my original library. I did hold down the shift key to open itunes but is still comes up with the new library. What am I doing wrong? I tried several times with no luck. Thank you.

I just got an Ipod Classic recently and downloaded Itunes. Got my music on my Ipod. My husband just got an Ipod Touch. I followed the directions on how to create a 2nd library and was able to load his music onto his Ipod. My problem is now I can not find my original library. I did what the directions said about holding down the shift key while opening Itunes and it still goes to the 2nd library that I created. How do i get my original library to come up? I tried several times with the same results. Please let me know what I need to do to be able to get into either library. Thank You.

Does the original library file still exist on the computer? Hopefully when creating the new library it was done in a seperate folder as I do not believe iTunes allows for two library files in the same location.

Creating a shared library for JNI in windows

I went through the JNi tutorial online and it worked just fine on a Linux computer. Now I'm trying to make do the same tutorial on windows. When I get to the step 4. Create a Shared Library, I'm stuck. I don't know how to create this shared library on windows. It gives an example using Visual C++ but I don't have that. Any tips or advice out there what I should do? Any help would be greatly appreciated.

//mac.java
class mac
    public native void getMac();
    private native String getLine(String prompt);
    static {
     System.loadLibrary("myMac");//This is myMac.DLL
     /*if generated by borland
     System.loadLibrary("mymac");//This is mymac.dll
     public static void main(String[] args)
    mac mc=new mac();
    String input = mc.getLine("Enter Some Thing ");
    System.out.println("You Entered " + input);
    System.out.println(mc.getMac());
prompt> javac mac.java
prompt> javah -jni mac
Borland compiler
/*mymac.c*/
#include <jni.h>
#include "mac.h"
#include <stdio.h>
JNIEXPORT void JNICALL
Java_mac_getMac(JNIEnv *env, jobject obj)
    printf("I am in getmac dir in mymac.dll (Borland) \n");
    return;
JNIEXPORT jstring JNICALL
Java_mac_getLine(JNIEnv *env, jobject obj, jstring enter)
    char buf[128];
    const char *str = (*env)->GetStringUTFChars(env, enter, 0);
    printf("%s", str);
    (*env)->ReleaseStringUTFChars(env, enter, str);
    scanf("%s", buf);
    return (*env)->NewStringUTF(env, buf);
To generate DLL
create bcc32.cfg file in %BORLAND_INSTALL%/BCC5/bin Folder
In the bcc32.cfg file add following code
-I"%BORLAND_INSTALL%\BCC55\include;%JAVA_HOME%\include;%JAVA_HOME%\include\win32"
-L"%BORLAND_INSTALL%\BCC55\lib;%BORLAND_INSTALL%\BCC55\Lib\PSDK;"
i.e the path for borland compiler and java.
now goto prompt and say
prompt>bcc32 -tWM -tWD mymac.c
This will create mymac.lib File
Now say
prompt>implib -c mymac.lib mymac.dll
That's it!!
there you are with dll
Now you can run the mac.class file by using java
VC++
Click File->New->Win32Dynamic-Link Library
Give name and Select
A simple DLL project
You will have
myMac.CPP file
// myMac.cpp : Defines the entry point for the DLL application.
#include "stdafx.h"
#include "mac.h"
#include "jni.h" //can copy or give full path
#include <math.h>
BOOL APIENTRY DllMain( HANDLE hModule,
                       DWORD ul_reason_for_call,
                       LPVOID lpReserved
    return TRUE;
JNIEXPORT void JNICALL
Java_mac_getMac(JNIEnv *env, jobject obj)
    printf("You are in getMac (VC++) DLL\n");
JNIEXPORT jstring JNICALL
Java_mac_getLine(JNIEnv *env, jobject obj, jstring enter)
    char buf[128];
    const char *str = env->GetStringUTFChars(enter, 0);
    printf("\n%s", str);
    env->ReleaseStringUTFChars(enter, str);
    scanf("%s", buf);

How to create a Transaction code for a Report Painter Report

Hi All,
Can any one let me know the procedure as to how to create a t-code for a user defined PCA report. I have created a PCA report (copied the existing report (8a26-001) and named it as zpca and assigned the same in a new Report Group ZPCA (the group is created by copying 8a26 group) and assigned it under the library 8a2. We have added few fields required by the user to the Z report.
Now i need to create a transaction code for that zpca report. can anyone suggest how to go about it.
Useful answers will be appropirately rewarded.

How to create different log files for each of web applications deployed in OC4J

Hi All,
I am using OC4J(from Oracle) v1.0.2.2 and Windows2000. Now I want to know
1. how to create different log files for each of my deployed web applications ?
2. what are the advantages in running multiple instances of oc4j and in what case we should run
multiple instances of OC4J ?
3. how to run OC4J as Windows2000 Service rather than Windows2000 Application ?
Thanks and Regards,
Kumar.

Hi Avi,
First of all I have given a first reading to log4j and I think there will some more easy way of logging debugging messages than log4j (If you could provide me a detailed explanation of a servlet,jsp,java bean that uses log4j and how to use log4j then it will be very helpful for me). The other easy ways (if I am not using log4j) to my problem i.e creating different log files for each of web applications deployed in oc4j are
I have created multiple instances of OC4J that are configured to run on different ports and so on each instance I have deployed a single web application . And I started the 2 oc4j instances by transferring thier error/log messages to a file. And the other way is ..
I have download from jakarta site a package called servhelper . This servhelper is a thread that is started in a startup servlet and stopped in the destroy method of that startup servlet. So this thread will automatically capture all the system.out.println's and will print those to a file. I believe that this thread program is synchronized. So in this method I need not run multiple instances of OC4J instead each deployed web application on single instance of oc4j uses the same thread program (ofcourse a copy of thread program is put in each of the deployed web applications directories) to log messages on to different log files.
Can you comment on my above 2 approached to logging debugging messages and a compartive explanation to LOG4J and how to use LOG4J using a simple servlet, simple jsp is appreciated ...
Thanks and Regards,
Ravi.

How to create the Access sequence for the Vendor+material+plant combination

Hi all
Please let me know How to create the Access sequence for the Vendormaterialplant combination..
Whats the use? What its effect in purhcase and taxe..
brief me please

Hi,
you are asked to maintain the access sequence for the tax condition for which you are putting 7.5%.
goto OBQ1 or img..financial accounting new...global settings.... taxes on sales and purchases ......basic settings.....
find the tax condition type. see in it which access sequence is attached.
if there is none then use JTAX used for taxes in India.
or you can create the similar one for your.
to create the same goto OBQ2.
new entry or copy JTAX.
and assign the access sequence to condition type.
this will resolve your problem if you just need to assign the access sequence.
