Re: SAVLIB/RSTLIB and external stored procedures

I've done that test. I've found that all SQL procedures are "restored"
(i.e. added to SYSPROCS) to the library being restored to, but any external
procedures are only restored if the object pointed to by the EXTERNAL
clause is in the library being restored to. I didn't test a scenario where
the EXTERNAL clause doesn't specify a library (which should then use *LIBL)
as we always specify the library qualifier there.

I am now in the process of moving all my external procedures into the
LIVEPGM library and adding the LIVEPGM library to the data connections used
by the website. We are still undecided about the SQL stored procedures
because they are database objects and belong in the database, but the
system actually creates programs for SQL procedures which then causes a
difference of opinions every time it is mentioned.

Thanks to everyone for their help.

-Paul.

I believe that IBM alters the internals on what is actually saved to media
(tape, save files, etc) to get the information from the system catalogs
also for things like stored procedures, etc. And the restore also handles
this.
Now some people are reporting interesting results. Like perhaps it's not
working as they believe it should.

I'm not questioning whether how they believe is good, bad or indifferent.
I'm just explaining my belief as to how save/restore handles this.

If I had more time I might try creating a small library with a stored
procedure in it.

Remember, the adepts would use the internals of save files to undelete
rows in tables. So there should be some way of seeing this stuff.

Does SAVLIB/RSTLIB save and restore other dependent objects that exist in
another library than the one you are saving/restoring? The only thing
CREATE PROCEDURE LIVEFIL/... stores in LIVEFIL is a record in an SQL
CATALOG. The stored procedure is in LIVEPGM. I tend to store my database
objects all together whether they are program objects or file objects or
something else. External stored procedures are a different animal though.
Those are a weird hybrid. May want to include LIVEPGM in your
SAVLIB/RSTLIB.

We're just starting with using stored procedures and are getting worried
that we'd have to maintain a list of stored procedures that need to be
manually re-created in a Disaster Recovery situation. Surely SAVLIB/RSTLIB
should be able to handle this by itself?.

Hi,

Does SAVLIB save external stored procedures? And does RSTLIB restore
them
to a different library?

I have a procedure created with:



CREATE PROCEDURE LIVEFIL/GETNEWCLAIMNUMBER(OUT REFERENCE INTEGER )

LANGUAGE RPGLE NOT DETERMINISTIC NO SQL EXTERNAL NAME

LIVEPGM/TR1406 PARAMETER STYLE GENERAL

Every night I save library LIVEFIL out to a tape. Much later in the
night
I
also restore LIVEFIL from that tape into library CLAIMFIL (after
completely
removing the older CLAIMFIL). Every morning the above procedure does
not
exist in CLAIMFIL. LIVEFIL and CLAIMFIL are not "schema", just plain
libraries.

With backup procedures of other DBMSs (e.g. MariaDB) all procedure and
table definitions are saved with the data backups, and on restore to a
new
database anything missing is recreated automatically.
