.SH SYNOPSIS
|
||
|
.sp
|
||
|
\fBmongooplog\fP is a simple tool that polls operations from
|
||
|
the \fIreplication\fP \fIoplog\fP of a remote server, and applies
|
||
|
them to the local server. This capability supports certain classes of
|
||
|
real\-time migrations that require that the source server remain online
|
||
|
and in operation throughout the migration process.
|
||
|
.sp
|
||
|
Typically this command will take the following form:
|
||
|
.INDENT 0.0
|
||
|
.INDENT 3.5
|
||
|
.sp

This command copies oplog entries from the \fBmongod\fP instance
|
||
|
running on the host \fBmongodb0.example.net\fP and duplicates
|
||
|
operations to the host \fBmongodb1.example.net\fP\&. If you do not need
|
||
|
to keep the \fI\-\-from\fP host running during
|
||
|
the migration, consider using \fBmongodump\fP and
|
||
|
\fBmongorestore\fP or another \fBbackup\fP operation, which may be better suited to
|
||
|
your operation.

\fBmongooplog\fP will not be able to copy oplog entries.

Changed in version 3.0.0: \fBmongooplog\fP removed the \fB\-\-dbpath\fP as well as related
|
||
|
\fB\-\-directoryperdb\fP and \fB\-\-journal\fP options. You must use
|
||
|
\fBmongooplog\fP while connected to a \fBmongod\fP instance.

\fI\-\-sslCAFile\fP, it will not attempt to validate

server certificates. This results in vulnerability to expired

\fBmongod\fP and \fBmongos\fP certificates as well as to foreign

processes posing as valid \fBmongod\fP or \fBmongos\fP

Unless you specify the \fI\-\-host\fP option,
|
||
|
\fBmongooplog\fP will apply the operations collected with this
|
||
|
option to the oplog of the \fBmongod\fP instance running on the
|
||
|
localhost interface connected to port \fB27017\fP\&.

.B \-\-oplogns <namespace>
|
||
|
Specify a namespace in the \fI\-\-from\fP host
|
||
|
where the oplog resides. The default value is \fBlocal.oplog.rs\fP, which
|
||
|
is the where \fIreplica set\fP members store their operation log.
|
||
|
However, if you\(aqve copied \fIoplog\fP entries into another
|
||
|
database or collection or are pulling oplog entries from a
|
||
|
\fBmaster\-slave\fP deployment, use \fI\%\-\-oplogns\fP to
|
||
|
apply oplog entries stored in another location. Namespaces take the
|
||
|
form of \fB[database].[collection]\fP\&.

Consider the following prototype \fBmongooplog\fP command:
|
||
|
.INDENT 0.0
|
||
|
.INDENT 3.5
|
||
|
.sp
|
||
|
.nf
|

.ft C
|
||
|
mongooplog \-\-from mongodb0.example.net \-\-host mongodb1.example.net

.ft P
|
||
|
.fi
|
||
|
.UNINDENT
|
||
|
.UNINDENT
|
||
|
.sp
|
||
|
Here, entries from the \fIoplog\fP of the \fBmongod\fP running
|
||
|
on port \fB27017\fP\&. This only pull entries from the last 24 hours.
|
||
|
.sp
|
||
|
Use the \fI\-\-seconds\fP argument to capture
|
||
|
a greater or smaller amount of time. Consider the following example:
|
||
|
.INDENT 0.0
|
||
|
.INDENT 3.5
|
||
|
.sp
|
||
|
.nf
|

mongooplog \-\-from mongodb0.example.net \-\-seconds 172800

In this operation, \fBmongooplog\fP captures 2 full days of
|
||
|
operations. To migrate 12 hours of \fIoplog\fP entries, use the
|
||
|
following form:

.INDENT 0.0
|

|
.INDENT 3.5
|
