• sqlplus / as sysdba don't work anymore after upgrade to 11R2

  Hello
  
  I just upgrade my 2 cluster nodes to 11R2 under window 2003 10.2.0.4.
  
  My group and my startup of the database without problem.
  
  The only problem, I'm not able to open a sqlplus with / as sysdba.
  
  If I connect with a listener (aka in the tnsname) I can access my database.
  
  In local mode, it is not possible (it's like I can't use my sqlplus in local mode).
  
  I have this message
  
  ERROR:
  ORA-12557: TNS:protocol adapter not loadable
  
  in my sqlnet.ora file, I always have the option AUTHENTICATION_SERVICES = (NTS)
  and my sqlplus associated new directory (11 GR 2). If I do a tnsping, I see that the new directory useless.
  
  I think I'm really into the problem and I do not see the solution, I need someone to another vision
  
  
  What can be my problem?
  
  Thank you

  After upgrade, you have now (at least temporarily) 2 ORACLE_HOMEs. ORA-12557 occurs when the version of the executable file and default ORACLE_HOME are not the same, that is, call you sqlplus 10g 11g ORACLE_HOME or vice versa.
  Make sure you only use sqlplus 11g and 11g ORACLE_HOME (YES ==> products installed ==> environment, moving % ORACLE_HOME % upward).

• sqlplus / as sysdba

  I am faced with the following question:

  On a database of eBS 11.1 data, I see that all known "sqlplus / as sysdba ' does not work, he responds with: become insufficient

  I have the password and as far as I can see, so the SYS password gets validated positively, but then he says I have to use the SYSDBA role to login as SYS, and that's the problem.

  So, I'm looking for a solution for this problem. Maybe if I can connect as SYS, but WITHOUT the SYSDBA role, which can solve the problem as well.

  What happened to cause this (because it must have worked in a first time), there was a database upgrade, which may have been the cause of this problem.

  The eBS environment is a Vision 12.1.3

  It is not a production, or a copy of a production database (to be clear about this)

  It seems that I found the solution:

  Very funny this TWO_TASK / ORACLE_SID. :-)

  CurrentY I can connect to sqlplus / as sysdba - I'm going to restore the virtual machine and try again if this is really the solution. :-)

  Hi guys,.
  Is it possible to put a password when you connect to sqlplus using sysdba?

  Hello

  Yes, the host is Windows Server 2003.
  I created a new service for the new SID. Followed all the steps to make the change

  How did you create the Oracle database Service? Have you used ORADIM to remove and create the new Instance?

  http://download.Oracle.com/docs/CD/B19306_01/win.102/b14304/create.htm#i1006533

  If you have created the new OracleServicePRTLservice, check who is started correctly.

  Then try a connection as follows from a DOS window:

  set ORACLE_SID=PRTL
  sqlplus / nolog
  connect / as sysdba
  

  Hope this helps.

• Question about the connection using the "sqlplus / as sysdba.

  Good afternoon
  
  The command:
  

  sqlplus / as sysdba

  worked very well for the Oracle server. When I go to a client, it does not work even if I specify the correct instance. On the client, I can able to connect using one of these two commands:
  

  sqlplus.exe sys/abc123@"orahost.john.local:1521/dbca.john.local" as sysdba
  
  or 
  
  sqlplus.exe sys/abc123@dbca as sysdba
  
  but not
  
  sqlplus / as sysdba
  
  or 
  
  sqlplus /@dbca as sysdba

  The question is: is the form "/ as sysdba" limited to used on the Oracle server and not available for customers?
  
  Thank you for your help,

• difference between sqlplus /nolog and sqlplus "/ as sysdba".

  HI ppl,
  
  Please help me with this... This is an emergency of lill
  
  On the oracle 10g platform, what is the difference between sqlplus /nolog and sqlplus "/ as sysdba".
  
  concerning

  Zombie says:
  Thnx for the people of responses,

  but not giving sqlplus/nolog... Disable writing to the Oder, the session is opened in mode nologing IE?

  concerning

  Laughing out loud

  Do not assume that everywhere where NOLOG is mentioned it means no. LOGGINg:-D. By sqlplus / nolog, you did nothing but had just the sql command prompt without really connecting as any user. You will still need to connect, by some users to start your work. This has NOTHING to do with do it again / cancel and anything else.

  The other command will actually to connect as user Sys with Sysdba role.

  That said, I STRONGLY suggest you to read this book for sure.

• How iCloud works for documents?

  So, I was working on a Word document between two different iMacs.  To keep the documents in sync, I have it stored the iCloud drive.  May 17, died the main iMac that I used to work.  Now I'm trying to restore the iMac that died, but I expected the document in phase.  When I went to my other iMac to continue working the iCloud drive shows the word document to have an update date of May 11.  Basically, I lost six days of work.

  I had assumed that iCloud drive could be used a shared drive between computers - like Dropbox or 1prediction.  But this isn't the case or something unusual broke my sync files to the cloud.

  So how does iCloud?  It is not synchronize whenever a file is updated, but uses another system?  I just want to understand how it works if it does not happen.

  Otherwise I could use Pages that seems to work as I expect to work the synchronization whenever there is a change, but in this case the word is the right tool, not Pages.

  Thank you.

• How cache works on an iPhone?

  Thus, if only a topic has an application that he has legally downloaded on the apple App Store in memory cache, video/audio from youtube videos. And it "covers" any song you want.

  1.) does take space on the memory embedded phones (iPhone 16 gb)

  2.) after about 500 songs cached will there be performance implications? Because that I do not know if the cache is an accessible memory write is in and of its own which would get clogged after a lot of files are cached.

  3.) why can't I just check the size of the apps file to see if it uses the said files system memory "cached".

  BASICALLY, I FOUND an ALTERNATIVE to ITUBE, where songs are "cached" actually stored? Do not want to waste space that I have only a 16 gb iPhone

  1 - Yes

  2 - Yes

  3. I think because that's not how iOS works.

  Is your phone jailbroken?

  How do you think your phone to store the songs without taking up space?
