Why to Upgrade or Migrate to Higher Versions of SQL server 2008 R2

SQLServerF1

Why upgrade or migrate to higher versions of SQL server 2008 R2 or SQL Server 2012 or 2014?
SQL server 2008 R2 or higher versions provides an enterprise data platform with great benefits which include, Minimizing business disruptions by increasing availability and scalability while significantly lowering IT costs. Gaining deeper business insight through richer end-user analytics and reporting tools that result in a faster return on investment. Accelerating the development time of line-of-business applications by up to 40 percent with Visual Studio and Microsoft .NET integration, including 50 to 70 percent code reduction for most scenarios. Reducing data management complexity and ease of manageability.

There are many new latest features available with each newer version of SQL Server which include some cool features like Multi-Server management, Resource Governor, Master Data Services, CDC, etc in SQL Server 2008 R2, AlwaysON Availability Groups, Enhanced Fail-Over clustering, Extended Events, from SQL Server 2012 onwards, In-Memory OLTP in SQL Server 2014 onwards. Also there has been huge improvement related to Business intelligence which include Dataware house support, SQL Server Reporting Service, SQL Server Analysis Services and Integration Services, PowerPivot and Self-Service BI, etc.

The upgrade or migration to higher versions of SQL Server has been made easier with new setup or installation interface which provides lot of options like repair, add cluster instance, add node to add additional nodes to SQL Server failover clustering instance, etc. Also, from SQL Server 2008 R2 onwards, Service Packs or Cumulative Updates can be uninstalled too. The logging also has been improved which provides more details regarding failure of in place upgrades or failure of service packs or Cumulative updates. Also, slip-streaming feature allows DBAs to merge the base RTM SQL Server media with Service Packs and apply to avoid any known issues and to keep the installation to complete smoothly as long as all the pre-requisites are fulfilled.

With each newer version release of SQL Server, support for older versions become outdated and new service packs or Cumulative updates will not be released for older versions. When there is any major problems, it may turn difficult to get support from Microsoft for older versions of SQL Server. Running with older versions of SQL Server instances poses great risk and threat to security or availability of the data during crisis, so it is always advisable to run with latest versions of SQL Servers which are consistent.

This is applicable on below versions of SQL Server

SQL Server 2008 R2
SQL Server 2012
SQL Server 2014

Oracle Database Errors or Warnings from Error ORA-01181 to ORA-01190

SQLServerF1

 

ORA-01181: file string created before last known RESETLOGS, cannot recreate
Cause: Attempted to use ALTER DATABASE CREATE DATAFILE to recreate a datafile that existed before the last known RESETLOGS.
Action: Find a backup of the file, and recover it. Do incomplete recovery to time before file was originally created.
ORA-01182: cannot create database file string – file is in use or recovery
Cause: Attempted to use ALTER DATABASE CREATE DATAFILE to recreate a datafile that is online in an open instance or is being recovered.
Action: Close database in all instances and end all recovery sessions
ORA-01183: cannot mount database in SHARED mode
Cause: Some other instance has the database mounted exclusive.
Action: Shutdown other instance then mount shared.

ORA-01184: logfile group string already exists
Cause: An ALTER DATABASE ADD LOGFILE command specified a log number for the new log which is already in use.
Action: Specify a different logfile number, or let the database choose an unused value.
ORA-01185: logfile group number string is invalid
Cause: An ALTER DATABASE ADD LOGFILE command specified a log number for the new log which is too large.
Action: Specify a correct logfile number.
ORA-01186: file string failed verification tests
Cause: The data file did not pass the checks to insure it is part of the database. See the accompanying error messages for the reason the verification failed.
Action: Make the correct file available to the database. Then, either open the database, or execute ALTER SYSTEM CHECK DATAFILES.

ORA-01187: cannot read from file string because it failed verification tests
Cause: The data file did not pass the checks to insure it is part of the database. Reads are not allowed until it is verified.
Action: Make the correct file available to the database. Then, either open the database, or execute ALTER SYSTEM CHECK DATAFILES.
ORA-01188: The block size specified string does not match header block size string
Cause: The block size specified in the BLOCKSIZE clause of the CREATE CONTROLFILE statement does not equate to the block size recorded in the log file header.
Action: Specify the correct block size.
ORA-01189: file is from a different RESETLOGS than previous files
Cause: In a CREATE CONTROLFILE command either this file or all previous files were backups from before the last RESETLOGS. This may also occur if this is a file that is offline and has been offline since before the last RESETLOGS.
Action: If the file was taken offline normal before the last RESETLOGS, and is still offline, omit it from the CREATE CONTROLFILE command. Rename and online the file after the database is open. Otherwise find the version of the mentioned file consistent with the rest of the datafiles and resubmit the command.
ORA-01190: control file or data file string is from before the last RESETLOGS
Cause: Attempting to use a data file when the log reset information in the file does not match the control file. Either the data file or the control file is a backup that was made before the most recent ALTER DATABASE OPEN RESETLOGS.
Action: Restore file from a more recent backup.

Oracle Database Errors or Warnings from Error ORA-01171 to ORA-01180

SQLServerF1

 

ORA-01171: datafile string going offline due to error advancing checkpoint
Cause: The checkpoint in the file header could not be advanced. See accompanying errors for the reason. The datafile will be taken offline the same as for a write error of a data block.
Action: See accompanying errors for details. Restore access to the file, do media recovery, and bring it back online.
ORA-01172: recovery of thread string stuck at block string of file string
Cause: Crash recovery or instance recovery could not apply a change to a block because it was not the next change. This can happen if the block was corrupted and then repaired during recovery.
Action: Do a RECOVER DATAFILE for the file containing the block. If this does not resolve the problem then restore the file from a backup and recover it.
ORA-01173: data dictionary indicates missing data file from system tablespace
Cause: Either the database has been recovered to a point in time in the future of the control file or a datafile from the system tablespace was omitted from the create control file command previously issued.
Action: For the former problem you need to recover the database from a more recent control file. For the latter problem, simply recreate the control file checking to be sure that you include all the datafiles in the system tablespace.

ORA-01174: DB_FILES is string buts needs to be string to be compatible
Cause: The maximum number of database files supported by this instance is not the same as for the other instances. All instances must be able to open all the files any instance can open.
Action: Change the value of the DB_FILES parameter to be compatible
ORA-01175: data dictionary has more than the string files allowed by the instance
Cause: The data dictionary is found to have more files than that which can be supported by this instance.
Action: Shutdown the instance and restart with a larger number of db_files
ORA-01176: data dictionary has more than the string files allowed by the controlfie
Cause: After a CREATE CONTROLFILE, the data dictionary was found to have more datafiles than that supported by the control file.
Action: Recreate the control file with a larger MAXDATAFILES.

ORA-01177: data file does not match dictionary – probably old incarnation
Cause: When comparing the control file with the data dictionary after a CREATE CONTROLFILE or OPEN RESETLOGS, it was noted that this datafile was inconsistent with the dictionary. Most likely the file is a backup of a file that was dropped from the database, and the same file number was reused for a new file. It may also be that an incomplete recovery stopped at a time when this file number was used for another datafile.
Action: Do a CREATE CONTROLFILE with the correct file or none at all.
ORA-01178: file string created before last CREATE CONTROLFILE, cannot recreate
Cause: Attempted to use ALTER DATABASE CREATE DATAFILE to recreate a datafile that existed at the last CREATE CONTROLFILE command. The information needed to recreate the file was lost with the control file that existed when the file was added to the database.
Action: Find a backup of the file, and recover it. Do incomplete recovery to time before file was originally created.
ORA-01179: file string does not exist
Cause: During datafile recovery, a file was listed which was not part for the database.
Action: Recheck the datafile name. Remember to use double quotes at the SQLDBA command line and remember that the file name is translated in the environment of the SQLDBA.
ORA-01180: can not create datafile 1
Cause: Attempting to create datafile 1 using ALTER DATABASE CREATE DATAFILE.
Action: Recover file from a backup or recreate database.

Oracle Database Errors or Warnings from Error ORA-01161 to ORA-01170

SQLServerF1

 

ORA-01161: database name string in file header does not match given name of string
Cause: The database name given at the command line does not match the database name found in the file header.
Action: Chance are good that the database name specified at the command line is incorrect. Resolve the descepency, and resubmit the command. If you are attempting to change the database name, be sure to use the SET DATABASE option.
ORA-01162: block size string in file header does not match configured block sizes
Cause: CREATE CONTROLFILE discovered that the block size for this file is incompatible with any of the configured cache blocksizes in the INIT.ORA file.
Action: Configure the appropriate cache for this block size using one of the various (db_2k_cache_size, db_4k_cache_size, db_8k_cache_size, db_16k_cache_size, db_32K_cache_size) parameters.
ORA-01163: SIZE clause indicates string (blocks), but should match header string
Cause: The size specified in bytes in the SIZE clause of the CREATE CONTROLFILE statement does not equate to the number of blocks recorded in the header.
Action: Specify the correct filename and size ( in bytes ).

ORA-01164: MAXLOGFILES may not exceed string
Cause: MAXLOGFILES specified on the command line too large.
Action: Resubmit the command with a smaller MAXLOGFILES
ORA-01165: MAXDATAFILES may not exceed string
Cause: MAXDATAFILES specified on the command line too large.
Action: Resubmit the command with a smaller MAXDATAFILES
ORA-01166: file number string is larger than string (string)
Cause: File mentioned in CREATE CONTROLFILE has a file number which is larger than that specified for MAXDATAFILES or MAXLOGFILES.
Action: Increase the maximum specified on the command line.

ORA-01167: two files are the same file/group number or the same file
Cause: There is an overlap of file numbers in the files specified on the command line or the same file is specified twice. If they are not the exact same file then one is likely to be a backup of the other. If they are two members of the same log they must be specified together in a group file spec. This message will also appear if the same control file appears more than once in the control_files parameter in the init.ora file. If this happens, check for additional error messages.
Action: Confirm that the file mentioned is not a repeat of a file already mentioned in the command. If they are different files then omit the earlier backup. If they are members of the same log, insure they are in the same group file specification. If this message appears because of a duplicate control file, check the control_files parameter in the init.ora file and see if a file is specified more than once. If all files names appear to be unique, check to make sure that the actual control files themselves are unique. For example, in UNIX check for a symbolic or a hard link to another control file in the list.
ORA-01168: physical block size string does not match size string of other members
Cause: The file is located on a device with a different physical block size than the other members in the group
Action: Use a physical device with matching block size.
ORA-01169: DATAFILE number 1 not found. Must be present
Cause: Datafile number 1 was not specified in a CREATE CONTROLFILE command.
Action: Locate datafile number 1 and resubmit the CREATE CONTROLFILE command.
ORA-01170: file not found ‘string’
Cause: ALL datafiles and, if NORESETLOGS, ALL logfiles MUST be accessible by the process for CREATE CONTROLFILE.
Action: The file specified probably contains a typing error. Double check command and the existance of all files and then resubmit.

Oracle Database Errors or Warnings from Error ORA-01151 to ORA-01160

SQLServerF1

 

ORA-01151: use media recovery to recover block, restore backup if needed
Cause: Error 1172 occurred.
Action: This is additional information for error 1172.
ORA-01152: file string was not restored from a sufficiently old backup
Cause: An incomplete recovery session was started, but an insufficient number of logs were applied to make the database consistent. This file is still in the future of the last log applied. The most likely cause of this error is forgetting to restore the file from a backup before doing incomplete recovery.
Action: Either apply more logs until the database is consistent or restore the database file from an older backup and repeat recovery.
ORA-01153: an incompatible media recovery is active
Cause: Attempted to start an incompatible media recovery or open resetlogs during media recovery or RMAN backup . Media recovery sessions are incompatible if they attempt to recover the same data file. Incomplete media recovery or open resetlogs is incompatible with any media recovery. Backup or restore by RMAN is incompatible with open resetlogs
Action: Complete or cancel the other media recovery session or RMAN backup

ORA-01154: database busy. Open, close, mount, and dismount not allowed now
Cause: Some operation is in progress that expects the opened/mounted state of this instance to remain the same.
Action: Wait for the operation to complete then retry. If attempting to do a shutdown, SHUTDOWN ABORT will work. If this is a shutdown of a standby database that is operating in NO DATA LOSS mode, you must shutdown the primary database first.
ORA-01155: the database is being opened, closed, mounted or dismounted
Cause: The requested operation needs the instance to be in a particular state but the state is being changed.
Action: Wait for the open, close, mount, or dismount to complete then retry the operation. If necessary, a SHUTDOWN ABORT will always work.
ORA-01156: recovery or flashback in progress may need access to files
Cause: Either media recovery, instance recovery, or flashback was in progress. The recovery or flashback in progress may need the files to which this operation is being applied.
Action: Wait for recovery or flashback to complete.

ORA-01157: cannot identify/lock data file string – see DBWR trace file
Cause: The background process was either unable to find one of the data files or failed to lock it because the file was already in use. The database will prohibit access to this file but other files will be unaffected. However the first instance to open the database will need to access all online data files. Accompanying error from the operating system describes why the file could not be identified.
Action: Have operating system make file available to database. Then either open the database or do ALTER SYSTEM CHECK DATAFILES.
ORA-01158: database string already mounted
Cause: Another instance has a database by this name mounted.
Action: Find which instance is still running. Perhaps you have not lost the control files after all.
ORA-01159: file is not from same database as previous files – wrong database id
Cause: Not all of the files specified in CREATE CONTROLFILE are from the same database. The database ID of this file does not match that from the first file specified.
Action: Please double check the list of files provided to the CREATE
ORA-01160: file is not a string
Cause: The named file in the DATAFILE or LOGFILE section of the CREATE CONTROLFILE command does not appear to be as stated.
Action: Please double check the mentioned file.

Oracle Database Errors or Warnings from Error ORA-01141 to ORA-01150

SQLServerF1

 

ORA-01141: error renaming data file string – new file ‘string’ not found
Cause: An attempt to change a data file’s name in the control file failed because no file was found with the new name.
Action: Make sure that the data file has been properly renamed by the operating system and retry.
ORA-01142: cannot end online backup – none of the files are in backup
Cause: None of the files were found to be in online backup when attempting to end an online backup.
Action: None. Online backup does not need to be ended for this tablespace.
ORA-01143: cannot disable media recovery – file string needs media recovery
Cause: An attempt to disable media recovery found a file that needs media recovery, thus media recovery cannot be disabled.
Action: Recover the offending file or drop the tablespace it belongs to and retry this command.

ORA-01144: File size (string blocks) exceeds maximum of string blocks
Cause: Specified file size is larger than maximum allowable size value.
Action: Specify a smaller size.
ORA-01145: offline immediate disallowed unless media recovery enabled
Cause: ALTER TABLESPACE … OFFLINE IMMEDIATE or ALTER DATABASE DATAFILE … OFFLINE is only allowed if database is in ARCHIVELOG mode.
Action: Take tablespace offline normally or shutdown abort. Reconsider your backup strategy. You could do this if you were archiving your logs.
ORA-01146: cannot start online backup – file string is already in backup
Cause: When starting an online backup it was noticed that an online backup was already started for one of the data files.
Action: End the first backup before beginning another.

ORA-01147: SYSTEM tablespace file string is offline
Cause: A file belonging to the SYSTEM tablespace has been marked offline by the DBA. The database cannot be started until all SYSTEM tablespace files are online and openable.
Action: Bring the file online.
ORA-01148: cannot refresh file size for datafile string
Cause: An operating system or device error occurred when retrieving the file’s size. The device on which the file resides may have been offline.
Action: Restore access to the device.
ORA-01149: cannot shutdown – file string has online backup set
Cause: An attempt to shutdown normally found that an online backup is still in progress.
Action: End the backup of the offending tablespace and retry this command.
ORA-01150: cannot prevent writes – file string has online backup set
Cause: An attempt to make a tablespace read only or offline normal found that an online backup is still in progress. It will be necessary to write the file header to end the backup, but that would not be allowed if this command succeeded.
Action: End the backup of the offending tablespace and retry this command.

ORA-01136: specified size of file string (string blocks) is less than original size of string blocks
Cause: A file size was specified in the AS clause of ALTER DATABASE CREATE DATAFILE, and the size was smaller the the size needed
Action: Create the file with a larger size.

ORA-01137: data file string is still in the middle of going offline
Cause: It was not possible to get the lock for a file that is offline when attempting to bring it online. The most likely cause is that the lock is still held by the instance that is took it offline.
Action: Wait a bit and try to online the file again.
ORA-01138: database must either be open in this instance or not at all
Cause: The requested operation can not be done when the database is mounted but not open in this instance, and another instance has the database open.
Action: Execute the operation in an open instance, open the datbase in this instance, or close the database in the other instances.

ORA-01139: RESETLOGS option only valid after an incomplete database recovery
Cause: The RESETLOGS option was given in ALTER DATABASE OPEN, but there has been no incomplete recovery session.
Action: Retry the ALTER DATABASE OPEN without specifying RESETLOGS
ORA-01140: cannot end online backup – all files are offline or readonly
Cause: All the files were found to be offline or readonly when attempting to end an online backup.
Action: None. Online backup does not need to be ended for this tablespace.
