But if I install the darabase even dbca on node secondary, all installed and executed successfully.

A someone has encountered this problem and solved?
Thanks in advance!
Hello
you are using IBM AIX PowerHA for your database (active/passive) configuration. then you just install the binaries 'once' on one of the nodes. then coordinate with your operating system administrator to configure the fail the test scenarios.
for your question. before you start the database, make sure that there are no "orphaned" oracle process using the UNIX grep command:
$ ps - ef | grep ora
Kill the oracle of the hanging of the process to release the lock on the database file handle:
$ kill-9
I hope this helps. Kind regards

Well, your trace file indicates that the above description is innaccurate: you did NOT create an undo tablespace undotbs2, you have created a undotbs2 permanent tablespace.
You may be able to repair this situation, like this:
startup nomount
ALTER system set undo_management = manual scope = spfile;
immediate stop
startup
create undo tablespace undo3 datafile ' / whatever/you.like ' size XXg;
ALTER system set undo_tablespace is undo3 scope = spfile;.
ALTER system set undo_management = auto scope is spfile;.
immediate stop

Cannot start Bootcamp, after you have added the partition using disk utility

recently I install the el capitan + windows 7 (using bootcamp), everything works fine after I add the third partition. (I anticipate the third partition will be use for dropbox, for mac and windows can sync-ing a dropbox for each folder).
After I've done the third partition and restart the system, I want OPTION and found no windows.

Windows Media Player cannot burn the files. If the burner is busy, wait until the current task is complete. If necessary, check that the burner is connected properly and that you have installed the latest device driver. ???
I just burn a CD with no problem at all. Using the same type of CD, brand new, I tried to burn another CD and got this error message:
Windows Media Player cannot burn the files. If the burner is busy, wait until the current task is complete. If necessary, check that the burner is connected properly and that you have installed the latest device driver.
I close all programs running, restarted my computer, changed on the devices tab, the speed of burning... everything I know to do and all the things I've read in these forums, no luck... still get the exact same message. No idea why my CD-writer has decided to stop working for me?

ORA-27037 standby after you have moved the primary files
I'm under Oracle 11.2 with a physical Data Guard configuration primary and standby on Solaris 10. Asked me to move all the files belonging to the primary to a new mount point. This includes the datafiles, tempfiles, ORLs, litigants and the controlfile. On the main file system files were located on /u07 and are now on /u03. Pending files are on /u07.
Here's what I did:
Cancel managed recovery and stop in standby mode.
Judgment of the primary.
A file system has copied on the primary /u07 to /u03.
Control_files primary init.ora file parameter to point to the new location on /u03 and change log_archive_dest_state_2 = DEFER
Renamed the primary spfile with a ".bak" then primary would begin by init.ora file.
Elementary school:
startup mount;
Run A SQL script to rename the data files, tempfiles, ORLs and SRls to the new location on /u03.
ALTER database open;
Create spfile from pfile;
stop immediately;
start-up; (so primary is now started with a spfile)
Standby:
Change these two lines in the init.ora file:
*.db_file_name_convert='/U03/oradata/mydb/','/U07/oradata/mydb /'
*.log_file_name_convert='/u03/oradata/MYDB/log','/u07/oradata/MYDB/log_ '
Note: When Eve was created first, someone created the ORLs with a different name of the primary. For example, major newspapers are named log1a, log2a and log3a. The day before, they are named log_1a, log_2a and log_3a.
Renamed the spfile Eve with a ".bak" then Eve would begin by init.ora file.
bootable media;
At this point, I have seen these errors in the standby alert log:
Errors in the /oracle/diag/rdbms/mydb_stby/MYDB/trace/MYDB_lgwr_27569.trc file:
ORA-00313: open failed for the members of Group 3, Journal of thread 1
ORA-00312: wire 3 1 online journal: ' / u07/oradata/MYDB/log3a.dbf'
ORA-27037: unable to get file status
SVR4 error: 2: no such file or directory
Additional information: 3
ARC3: Started archiving
ARC0: FROM PROCESS ARCH COMPLETE
Here are my questions: why is the database ensures looking for online newspapers as they are named in the primary? (Without the underline in the name)
Should I have set STANDBY_FILE_MANAGEMENT = MANUAL on the primary and standby and renamed implementing the ORLs in the standby?
What I ended up doing was closing the day before and rename the ORLs on the filesystem depending on how they are named on the primary. Then, the day before, I did:
startup mount;
change retrieve in database managed automatic standby database using the current log file disconnect from the session;
Then, on the primary, I did: alter system set log_archive_dest_state_2 = ENABLE;
Everything looks OK, which means, newspapers are shipped from the primary to the standby and applied on the day before.
I wonder, what would I have done differently to avoid first encountered this error? Also, is my valid Eve at this point? I see no problem in the primary alert log or journal alerts in mode standby.
Mimi Miami wrote:
Thank you, CKPT. Now, I understand my misunderstanding with the log_file_name_convert parameter. The parameter is used to convert file locations of the ORLs on standby, not the name of the file of the BDL himself, correct? Knowing this, would it not imperative that the file is named game? In other words, I can't have an ENT named log1a on the primary with his match on the eve log_1a appointed, right?
Yes, setting gives way where to redirect the log files, but what happens if the mentioned directory does not exist on the database pending?
As on previous day $ls ltr - / u07/oradata/MYDB/log_
When there is no available pending directory as you have not mentioned in LOG_FIILE_NAME_CONVERT then it cannot translate the strings either.
File names, you can have anything but basically LOG_FIILE_NAME_CONVERT is here to rename the log files if there are in different places.

SRM does not start after you have moved the database
We're under 4.1 SRM and moved its sql database to a new server sql (new server sql a different host name). We moved successfully to the virtual center & Manager Update bases sql data, but after moving srm4.1 database, the srm service does not start...
so far, I uninstalled SRM (DO NOT remove the SRM database)... After uninstalling SRM, I rebooted the server. Then I have re-directed the SRM installation and started going through the installation of MRS... After pointing the SRM installed on the server vcenter, port 80, and pointing to an existing sql database, etc., I get a thumbnail of certificate message and a prompt on the creation of a new certificate, which i say 'yes' to... Installation continued on and arrived at the end when it says "create certificate"... then does not say "cannot install the certificate...". Database error has occurred. "At this point, the installation failed
Any ideas on how to remove the old certificate or work around this error?
Thank you
I think the error message is misleading in this case and the problem is not related to the certificate.
I still think that it is permission DB / configuration number.

After you install SP3, PC does not restart in normal mode, only in safe mode, without giving a clear indication of what is the problem or how to fix it - other than say to check settings in the Panel (not very useful).
PC is a Compaq Presario desktop with AMD processor, model #: SR1720AN product #: EL540AA-ABG
I reinstalled the operating system recovery disks, which reformats HD and installed XP with SP2.
I then installed the SP3 from a flashdrive (361 MB files). Everything went without hiccups, but final restarts, he won't get to normal mode, safe mode only.
I did it twice.
Any ideas? Thank you.
Here are the specifications of your desktop Compaq Presario SR1720AN. According to the specification, this model comes with a processor AMD and Windows XP Home Edition SP2 installed at the factory. According to your description, it seems that the HP recovery discs may have been poorly photographed for an AMD-based computer. Please see this Microsoft article and this HP document about your problem.
To solve your problem, please reinstall Windows XP SP2 by booting from your HP recovery disks. After Windows XP SP2 is complete restored and that your computer is operational, download the "Windows XP SP3 with AMD CPU upgrade utility." Run this utility, and then restart your computer. Then download the "Windows XP Service Pack 3 Package of Network Installation" for it professionals. You can also try to use the SP3 Installer on your USB. Install the update to Windows XP SP3 and then restart when you are prompted to.
This solve your problem?

As a work around, I am able to scroll through the list and make your choice with the keys on my keyboard. Not really ideal if!
Any suggestions?
No, if it works in another account we need not the test Mode without failure.
Make sure InDesign is closed, then:
See replace your preferences for the paths to the TWO hidden folders where the prefs are located and rename or delete them in the original user account. A copy of these two entire folders, not only the content from the account that works and stick to the appropriate locations in the account which is not.

If you guys tell me to check and make sure that the CD burner is connected; been there, done that.
If you guys tell me to uninstall the device, then reinstall; He does that
If you guys tell me to try new disks; summer it does this as well.
I lowered the burn speed ect.I did everything possible. I can burn a disc once or a little then next I get this error.
I still have to burn the disc from system restore and I fear for fear of getting this error. I think I have the external writer since bad things is a good idea to test things before putting.

Windows 8 cannot connect to the external hard drive after you have added the drive case.
Original title: I have my hard drive from my previous PC attached to my new PC with windows 8. My old PC had XP. How to access the external hard drive?
I had problems with my XP operating system and could not transfer all the files to my new PC. I spoke with Dell who I believe created the problem with software support. I was told to get out the hard drive, buy a hard drive enclosure and get my files from there. I can't find the hard drive.
Hello
Thank you for the update.
Given that the problem occurs when the hard drive is connected to a different USB port or another computer, it is probably related to the connection of the hard disk.
Method 1: check if the problem occurs in another computer after removing the hard disk enclosure.
Method 2:
Step 1: Check if the hard drive is detected in Windows Explorer.
To do this, follow these steps:
a. connect the hard disk of the computer.
b. press the Windows key + E to open Windows Explorer.
c. check if the hard drive is present here.
Step 2: Check if the hard drive is detected in disk management.
To do this, follow these steps:
a. on the desktop, press the Windows key + X , and then select disk management.
b. check if the hard drive is listed there.
Contact the manufacturer of the hard drive and hard drive enclosure for assistance.
