The Save and Send Library with FTP tool is designed to simplify
sending one or more libraries to another i5 System. Your objects
should be placed in unique libraries. The SAVSNDL command saves your
library to a save file and the save file is transmitted using FTP.
On the remote system, use RSTSNDL (part of the SAVSNDL tool) to
restore the library.
A separate command SBMSAVSNDL should be used to submit the SAVSNDL
command to batch (see the later discussion).
FTP requires the proper TCP/IP connections and configuration.
SAVSNDL differs from the system SAVRSTLIB command in that TCP/IP is
used. SAVRSTLIB uses APPN.
The SAVSNDL function is a simple front end to the TAA FTP2 command.
It is designed for transferring a library.
When using SAVSNDL, you must identify the remote system, a user
profile on that system, and the password for the profile.
A typical command on the source system would be:
SAVSNDL LIB(ABC) RMTSYS(xxx) RMTUSER(uuu) RMTPWD(ppp)
By default, a save file by the name of ABC would be created in the
TAAWORK library on the other system. TAAWORK is shipped with the TAA
Productivity Tools product and is used for temporary objects. If the
save file already exists, it is cleared first.
A user on the remote system can then enter the RSTSNDL command (part
of the SAVSNDL tool) to restore the library. A typical command would
be:
RSTSNDL LIB(ABC)
By default, it would restore from the ABC save file in TAAWORK. If
the ABC library already exists, you must specify DLTLIB(*YES).
RSTSNDL is designed to work with save files created by SAVSNDL. It
can be used with any save file, but the data within the save file
must have been saved by a SAVLIB command.
RSTSNDL does not have all the parameters of the RSTLIB command. If
you need the additional function, use the RSTLIB command.
SAVSNDL uses the TAA Tool FTP2.
SBMSAVSNDL Command
------------------
The command SBMSAVSNDL is intended for use when you want to submit
the SAVSNDL command.
SBMJOB can be used to submit the SAVSNDL command, but the value of
the RMTPWD parameter is left in the job log of the user that did
SBMJOB. To avoid leaving the password in the clear, you should use
SBMSAVSNDL.
All the parameters of SAVSNDL exist on the SBMSAVSNDL command plus
the JOB, JOBD, and JOBQ parameters. The additional parameters all
have default values.
The password value does not appear in the job log of the current user
if SAVSNDL is used interactively or SBMSAVSNDL is used. If SAVSNDL
is submitted to batch by either SBMJOB or SBMSAVSNDL, the password
value does not appear in the job log of the submitted job.
Typical use of SAVSNDL and RSTSNDL
----------------------------------
The need to transfer objects between systems is a fairly typical
requirement. In many cases, the objects to be transferred may be
part of a large library, but only a few need to be replaced on any
one transfer.
This can be accomplished by having work libraries on the source and
target system such as TMPTFR. You would perform the following steps
on the source system:
CLRLIB LIB(TMPTFR)
MOVOBJ ... TOLIB(TMPTFR)
SAVSNDL LIB(TMPTFR) ...
On the target system, you would enter:
RSTSNDL LIB(TMPTFR) DLTLIB(YES)
You would then enter the commands to move or copy the objects from
TMPTFR to the large library.
Error handling
--------------
SAVSNDL invokes the TAA FTP2 command.
FTP2 provides for a log of the FTP operations. If the SAVSNDL
command is run interactively, the log may be displayed using:
DSPPFM QTEMP/FTPOUT
If the SAVSNDL command is run in batch, a spooled file of the log is
created.
Why is a save file used
-----------------------
FTP only sends files. Therefore, other object types such as programs
or data areas cannot be sent directly. By saving a library to a save
file, there are essentially no restrictions.
If FTP is used to send a file, the unique i5/OS attributes will be
lost. This includes such attributes as the text of the file or
members and the source type. These problems are avoided by saving a
library to a save file.
Note that the text description of the save file is lost, but not the
attributes of the objects within the save file.
Using a CL program
------------------
A CL program may be used to include one of the SAVSNDL commands. The
disadvantage of this approach is that you must include your password
in the source.
If you are going to call the program in an interactive session, you
could use the selective prompting function such as:
SBMSAVSNDL ??LIB(x) ?*RMTSYS(y) ?*RMTUSER(z) +
??RMTPWD()
MONMSG MSGID(CPF6801) EXEC(DO) /* User cancelled */
/* Your code for cancel */
ENDDO /* User cancelled */
When the CL program is run, the SBMSAVSNDL command prompt would
appear with the values as specified and you must enter a password.
The other parameters on the command (eg TGTRLS) would not appear.
The selective prompting functions are as follows:
??LIB(x) The prompt appears with the library name, but can be
changed.
?*RMTSYS(y) The prompt appears with the remote system name and
cannot be changed.
?*RMTUSER(z) The prompt appears with the remote user name and
cannot be changed.
?*RMTPWD() The prompt appears and must be entered.
If you want to run a SAVSNDL command without prompting for the
password, you could hard code the password.
An alternative is the RTVMSKPWD tool which will allow you to return a
masked password. This is more secure than hard coding a password in
the source, but not as good as a validation list.
SAVSNDL escape messages you can monitor for
-------------------------------------------
None. Escape messages from based on functions will be re-sent.
SAVSNDL Command parameters *CMD
--------------------------
LIB Up to 300 libraries to save and send to the remote
system. Each library is saved to an internal save
file and then FTPed to the remote system.
RMTSYS The remote system to send to. Either a name or an
IP address must be entered. The proper TCP/IP
connections and configuration must exist.
RMTUSER The name of the user on the remote system that will
be used for the job to be run on the remote system.
RMTPWD The password of the user on the remote system.
If SAVSNDL is entered interactively, the password is
not displayed and will not appear in the joblog.
If SBMJOB is used for SAVSNDL, the password as keyed
will appear will appear in the command prompt and in
the current job log. It will not be in the batch
job log.
See the SBMSAVSNDL command which removes the
password from current job log.
RMTLIB The remote library to place the save file in. The
default is TAAWORK which is the work library
provided by the TAA Productivity Tools product. If
the save file does not exist, it will be created.
If the save file exists, it is cleared before
writing to it.
If the target library does not exist, the save file
will be written to the users current library
(assuming the initial directory is *CURLIB).
SAVF The save file name to be used. The default is *LIB
meaning the same name as the library. If more than
one library is specified for the LIB parameter,
SAVF(*LIB) must be used.
TGTRLS The target release to save the library for. The
default is *CURRENT.
Use the prompter to see the other values which have
the same definition as the TGTRLS parameter on
SAVLIB.
RSTSNDL Command parameters *CMD
--------------------------
RSTLIB The library to be restored. The name may differ
from the library that exists in the save file.
SAVF The qualified name of the save file to restore from.
The default is to use the library name defined by
the LIB parameter as the save file name in the
TAAWORK library.
DLTLIB A *YES/*NO parameter for whether to delete the
library if it exists. The default is *NO meaning
the library does not exist. An error will occur if
the library does exist.
*YES may be specified to delete the library before
restoring from the save file. You must have all
rights to the library to be able to delete it.
SAVFLIB The library name within the save file. The default
is *ANY meaning that whatever library is found in
the save file will be used.
*LIB may be specified to mean the library name in
the save file must match that used in the LIB
parameter.
A specific name may be entered meaning the name must
match the library found in the save file.
DLTSAVF A *YES/*NO parameter for whether the save file
should be deleted after the restore is complete.
*YES is the default to delete the save file. The
save file is retained if errors occur on the
restore.
*NO may be specified to retain the save file.
SBMSAVSNDL Command parameters *CMD
-----------------------------
LIB The library to save and send to the remote system.
The library is saved to an internal save file and
then FTPed to the remote system.
RMTSYS The remote system to send to. Either a name or an
IP address must be entered. The proper TCP/IP
connections and configuration must exist.
RMTUSER The name of the user on the remote system that will
be used for the job to be run on the remote system.
RMTPWD The password of the user on the remote system.
The purpose of SBMFTP2 is to prevent the password
from existing in the current job log.
Because the FTP2 command is submitted by SBMFTP2,
the password will not exist in the job log for the
batch job either.
RMTLIB The remote library to place the save file in. The
default is TAAWORK which is the work library
provided by the TAA Productivity Tools product. If
the save file does not exist, it will be created.
If the save file exists, it is cleared before
writing to it.
If the target library does not exist, the save file
will be written to the users current library
(assuming the initial directory is *CURLIB).
SAVF The save file name to be used. The default is *LIB
meaning the same name as the library.
TGTRLS The target release to save the library for. The
default is *CURRENT.
Use the prompter to see the other values which have
the same definition as the TGTRLS parameter on
SAVLIB.
JOB The job name assigned to the batch job. The default
is SAVSNDL. *JOB may be entered to mean the name of
the job description used.
JOBD The qualified name of the job description. The
default is *USRPRF meaning the job description
assigned to the current user profile.
If a specific job description is entered, a library
qualifier may be entered or the special values *LIBL
or *CURLIB.
JOBQ The qualified name of the job queue to be used. The
default is *JOBD meaning the job queue defined for
the job description specified for the JOBD
parameter.
