Parameters
DBEnvironmentName is the name of a Wrapper DBEnvironment.
Must be the name of an empty
DBEnvironment previously created to wrap
around the log files.
MaintenanceWord is the maintenance word. Must be the
maintenance word of the DBEnvironment.
Wrapper Mode is the mode. Log is the default and only
mode presently allowed.
LogFileName1 physical name of a log file that is to be
wrapped.
Convert to Wrapper converts the empty DBEnvironment to a
DBEnvironment wrapper DBEnvironment or gives you the
opportunity to exit this command without
wrapping a DBEnvironment around the
orphaned log file(s).
Description
* This command wraps a DBEnvironment around log files orphaned after
a hard crash of a DBEnvironment.
* The DBEnvironment can be empty or it can have tables on which
updates have been performed.
* No updates can be made to the DBEnvironment after it has been
converted to a wrapper DBEnvironment with this command. Any
updates must be performed before this command is issued.
* The log files around which the DBEnvironment is to be wrapped must
be valid and must be marked as usable log files before this
command is used. Refer to the section of this manual that
describes wrapper DBEnvironment use.
* The log files entered should constitute a correct log file
sequence list with no sequence numbers missing. If the
DBEnvironment that crashed has dual log files, then log file names
can be taken from either of the dual log files, as long as they
constitute a proper sequence. The proper list of log files must
be determined before using the WRAPDBE command.
* The DBEnvironment to be wrapped around the orphaned log files must
be created before the WRAPDBE command is used. The DBEnvironment
is created with the START DBE NEW statement. Refer to the
"Setting up a Wrapper DBEnvironment" section of the "Backup and
Recovery" chapter of this manual.
* WRAPDBE prompts for the names of files around which the WrapperDBE
is to be wrapped. WRAPDBE does not accept more than one file name
on a single line.
* Any log files associated with the wrapper DBEnvironment before it
is converted are removed. Only the wrapped log files are
associated with the DBEnvironment after the WRAPDBE command is
executed.
For more information, refer to the "Backup and Recovery" chapter.
Authorization
You must be the superuser (HP-UX) or system administrator (MPE/iX) or
DBECreator of the original inaccessible DBEnvironment to use this
command.
