How to recover the old mysql database?
Hi. I did un upgrade of my Leopard to Snow (not Server). I've made a "Carbon Copy" and erase all my HD to restart everything, as the old Lopard was allready "fat", malfunction, etc..
I've forgot of MySQL! I'm re-installing but I'll have to export all databases I got online back to my machine (the oposite way). This is not really good because my local versions got users for testing only, less size for testing purposes... anyway, will be good take back my databases!
I boot from the copy but Apache didn't start up, don't know why, this will be a hard job (couldn't be easy uhn, export all by phpmysql).
I think the easy way is found the archives (the files that containing the databases) and copy back to newer installation...
Any ideas?
Hi
When you boot from cloned backup, does mysql work in terminal?
So open terminal, type mysql
If yes then you can do a mysql dump to file then install on new setup.
http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html
http://www.devarticles.com/c/a/MySQL/Backing-Up-Your-MySQL-Databases-With-MySQLD ump/
This way you should not need apache running to move the sql files across.

How to recover the database when some of the archive log file get deleted.
I am facing a problem with Oracle database, which is related to archivelogs.
Our development database is running in archivelog mode, but we don't have backups scheduled and have no recovery catalog.
When the database was in running condition, disk got full, so some archivelogs were deleted manually.
After this they restarted the DB, and now DB is not coming up. Errors are as follows:

Edited by: hem_Kec on Sep 7, 2008 9:07 AMHi,
Archive log files are the copies of redolog files.As redo log files are circularly overwritten,oracle generates archive log file of the corresponding redo logfiles being overwritten.So if you have a backup that dates back to 10 am in the morning and if your database creashed at 3 pm,you cannot use the redo log files alone as they have incomplete information.To completely recover the database upto 3 pm,you need archive log files generated between 10 am to 3 pm. In your case since you are missing one archive log file,you cannot perform complete recovery and hence would suffer data loss. -

How to recover the deleted reports from crystal reports XIR2
Hi,
There have been few crystal reports have been deleted from crystal environment and i would like to know how to recover them. please advice the best possible ways to recover them. CMS repositoty in SQL server database
thanks in advance
Regards,
KrishnaHope, your question is this "How to recover the deleted Crystal reports in XI R2".
Answer for this question is...
Yes, it is possible if you have backup of your CMS and FRS.
Copy the CMS database from the backup to your database server and point the CMS ODBC system DSN to it.
Copy the backed up file store to a Temp directory.
Change the path of input and output file repository servers in the CMC, for each server, to the Temp file store directory.
You will now be able to find the reports. Copy those reports to the BO server's local disk, or create a BIAR file using the Import Wizard.
Point the ODBC system DSN back to the original database and also change the paths on input file repository and output file repository servers back to their original locations.
Publish the reports to Enterprise from the BusinessObjects server's local hard disk. -
Due to reinstallation of mac 2nd partition is nt showing how to recover the partition and data
Due to reinstallation of mac 2nd partition is nt showing how to recover the partition and data
If you have no backup your only option is to perform incomplete recovery (point-in-time recovery) to the time just before the drop, export the table and then restore the database (for example, from a cold backup taken just before the incomplete recovery,) and import the table. This obviously requires a full backup
taken before the drop which you don't seem to have, so the answer is "regrettably no."
If you have a backup;
Take backup of ur current db, apply previous day backup, do point in time recovery to get table back,export table, shutdown and apply latest backup, import table back

Help downgrade a php script generated by FB back to the old Mysql way
hey all
i am a Flex developer who has written server side stuff with php scripts that were auto-generated by Flash Builder. These scripts use the Mysqli extention, which is not avilable on my shared hosting server. These scripts implement simple CRUD functions to a MySql database. Anyone who has used the data wizard will recognize these scripts.
Just before i pay more bucks and move to a VPS server in order to enable Mysqli, is there anyone out there who can help me translate this script BACK to the old mysql way?
much appriciated, Saar

How to recover the itunes music from other computer
i am using windows 7 64bit (computer B) with itunes. suddenly i lost the music from the itunes. i have another computer windows 7 32 bit (computer A) with itunes. how to recover the music from computer A to computer B
thanks
jimmyMain thing is why would you be losing your music in iTunes. If it happened during an update and that's why you need to refer to the article to restore your old library.
However, if you want to move iTunes from old computer to new computer:

When one of contolfile is corrupt then how to recover the controlfile?
when one of contolfile is corrupt then how to recover the controlfile?
Let us say we have 3 control files and they are named as "cont01.ctl,cont02.ctl & cont02.ctl" and they are stored in three different mount points (/u01,/u02 & /u03)
first controlfile -> /u01/oradata/prod/cont01.ctl
second controlfile -> /u02/oradata/prod/cont02.ctl
third controlfile -> /u03/oradata/prod/cont03.ctl
1. According to the ALERT log file or any other source let us say the third controlfile got corrupted...
Now , what you can do is you have to shutdown the database and remove cont03.ctl and copy it form cont01.ctl or cont02.ctl :
$ cd /u03/oradata/prod
$ rm -rf cont03.ctl
$ cd /u01/oradata/prod
$ cp -r cont01.ctl /u03/oradata/prod/cont03.ctl
Now, you can go ahead and start the database. The database will start without any issue and it wil be ready for any operations on it..
2. Suppose all the files of the database got corrupted ... First of all you need to have backup of the database... the steps that are needed of this scenario are :
--> shutdown the database with abort option
--> Assuming its RMAN backup .. you have to first start the database in nomount state and you have to restore the contolfile from the last backup been taken and start the database in mount state and then perform the database recovery and open the database with resetlogs option(since you dont have current controlfile becoz you have restored it from a backup) :
Assuming its catalog:
$ rman target / catalog usr/pawd@tns
RMAN> STARTUP NOMOUNT;
RMAN> restore controfile (from autobackup) ; -- in case you have auto backup then use the autobackup option
RMAN> alter database mount ;
RMAN> recover database;
RMAN> alter database open resetlogs ;
After the database gets opened , immediately you have to take the backup..
Hope its clear...Cheers! -
Hi there,
I was using MacPro with older snow leopard just now i install OS X LION,before install i backup all deta to time machines about 70GB,now when i connect i dont know how can backup the old deta to OS X LION,but it just backup the recent deta to time machine,pls guide me how i can backup my old deta to my computer??
Will be much appreciated !!
Thanks.>Step 1. Backup existing data using time machine.
Time Machine is nice, but you have very little in terms of ability to verify that your data is all backed up. I find Time Machine is better for the occasional recovery of previously written data at specific times. A good backup solution that survives an erase and install (there is no clean install in Mac OS X), is a clone, and preferably TWO clones. See my FAQ*:
http://www.macmaps.com/backup.html
Time Machine can work as good as a clone, and in fact I once had to rely on it because my hard drive died. Thankfully it did recover everything. But I had my clone just in case it didn't work. Now I feel more comfortable since clones allow you to boot themselves, and thus prove all the important system information got saved, and not just the user data.
Clones are also easier to import with the migration assistant. -
How to delete the old code in the EXIT_SAPLRSAP_001
Hi All,
In R3 system, I wrote an exit for 2LIS_11_VAHDR by using T-code CMOD in the function exit EXIT_SAPLRSAP_001 and the code does not meet my requirement today i want to delete the code and i will write the fresh one. now my problem is i am not able to delete the code can any body suggest me how to delete the old code.
and can we create new project and can we assign to the Enhancement RSAP0001.
Can anybody suggest me in this
Thanks in advance......
NarendraHi Narendra,
You can put the code in comments, if you don't want to use the old code..You can delete also..But be sure that code belongs to you only..
SE38>zxrsau01>change-->find out your data source
Comment(Or can delete) the code starting from WHEN '2LIS_11_VAHDR'. to the end of the code that you have written..
If you really want to delete the assignment of RSAP0001 to your old project>goto CMOD>your project name>change>delete assigment
Then create a new project and assign the enhancement RSAP0001 to your new project and write the code in Include 'ZXRSAU01'..
Hope it helps
Thanks
