how to run multiple scp commands from single scripts.
In a directory oracle redo files accumulate. i would like to copy those redo logs to my standby server. For same i am using scp to copy the files. where i am monitoring that as it is sending the files sequentially most of bandwidth unused. I am thinking to do multiple scp session to copy the files. how can i achieve it. I am listing the files to one file and i am splitting that file in to multiple files each file will contains 10 entries.
i.e. if file contains 100 entries then it will split that file to 10 files. and Each spitted file will have the entries like below.
how can i achieve to run 10 scp session parallely and use that 10 sub-files created as input for transferring the files to my standby server with successfully and using proper utilizing the bandwidth available.
Am working on AIX machine.
Kindly Help me on this.
Thanks Dears, Waiting for all your suggestion.
Thanks in advance...

But above command doesn't works, it simply runs the second command, ignoring the 1st one.

scp
SCP(1) BSD General Commands Manual SCP(1)NAME
scp -- secure copy (remote file copy program)
SYNOPSIS
scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-S program] [[user@]host1:]file1 ...
[[user@]host2:]file2
DESCRIPTION
scp copies files between hosts on a network. It uses ssh(1) for data transfer, and uses the same authentication and provides the same secu-
rity as ssh(1). Unlike rcp(1), scp will ask for passwords or passphrases if they are needed for authentication.
File names may contain a user and host specification to indicate that the file is to be copied to/from that host. Local file names can be
made explicit using absolute or relative pathnames to avoid scp treating file names containing ':' as host specifiers. Copies between two
remote hosts are also permitted.
When copying a source file to a target file which already exists, scp will replace the contents of the target file (keeping the inode).
If the target file does not yet exist, an empty file with the target file name is created, then filled with the source file contents. No
attempt is made at "near-atomic" transfer using temporary files.
The options are as follows:
-1 Forces scp to use protocol 1.
-2 Forces scp to use protocol 2.
-3 Copies between two remote hosts are transferred through the local host. Without this option the data is copied directly between the
two remote hosts. Note that this option disables the progress meter.
-4 Forces scp to use IPv4 addresses only.
-6 Forces scp to use IPv6 addresses only.
-B Selects batch mode (prevents asking for passwords or passphrases).
-C Compression enable. Passes the -C flag to ssh(1) to enable compression.
-c cipher
Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1).
-F ssh_config
Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1).
-i identity_file
Selects the file from which the identity (private key) for public key authentication is read. This option is directly passed to
ssh(1).
-l limit
Limits the used bandwidth, specified in Kbit/s.
-o ssh_option
Can be used to pass options to ssh in the format used in ssh_config(5). This is useful for specifying options for which there is no
separate scp command-line flag. For full details of the options listed below, and their possible values, see ssh_config(5).

-P port
Specifies the port to connect to on the remote host. Note that this option is written with a capital 'P', because -p is already
reserved for preserving the times and modes of the file in rcp(1).
-p Preserves modification times, access times, and modes from the original file.
-q Quiet mode: disables the progress meter as well as warning and diagnostic messages from ssh(1).
-r Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal.
-S program
Name of program to use for the encrypted connection. The program must understand ssh(1) options.
-v Verbose mode. Causes scp and ssh(1) to print debugging messages about their progress. This is helpful in debugging connection,
authentication, and configuration problems.
EXIT STATUS
The scp utility exits 0 on success, and >0 if an error occurs.
