SOFTWARE NOTES:
o Online Backups
--------------
The use of the -o (overlap factor) is not supported in this
release; you must restore the incremental backups exactly the
same way as you did when you backed them up or you will have
problems. For example,
proshut demo -C online /dev/rst8
proshut demo -C online /dev/rst8 incremental -o 2
After restoring the full backup, if you skip any of the
incrementals, you receive an error message indicating that
the tapes are out of sequence and the restore fails.
Workaround: Make sure all backups are restored in exact order.
o Fast Track (convft)
-------------------
If you use the convft utility to convert your database to a
Fast Track database, you must set the PROEXE environment
variable first:
PROEXE=/usr/dlc/_progres;export PROEXE
convft database-name
o Fast Track (500 file limit)
---------------------------
Unlike earlier versions, Fast Track Version 6.2F and
above enables you to choose from more than 500 files when
creating QBF's, reports or forms. Now there is no limit to the
number of files you can select. However, because of internal
changes to the Fast Track code, you must recompile any QBF's
or menus generated with earlier versions of Fast Track to run
them under Version 6.2F or above.
o REMOTE GATEWAYS
---------------
In PROGRESS Version 6.2F and above, you can remotely access an
Oracle or RMS database. To do this, you must install a Version
6.2F (or later) core PROGRESS product (for example, PADS,
4GL&RDBMS, Query Report, or Runtime) on the machine where you
are running your PROGRESS application and on the machine
hosting your non-PROGRESS database.
o REMOTE ORACLE GATEWAY
---------------------
While using the remote ORACLE gateway, if you press
CTRL-C during a transaction, you are disconnected from
the remote ORACLE server.
o PROBUILD
--------
o When running PROBUILD, the $PROLOAD/eucapp/euc.pl file must
have at least read and write permissions (rw-rw-rw-), otherwise
you will get the error:
** Cannot find or open euc.pl errno 13
To avoid this error, change the permissions on the euc.pl
file as follows:
chmod 666 $PROLOAD/eucapp/euc.pl
where $PROLOAD is an environment variable set to where
you have the dlcload directory installed - /usr/dlcload
by default.
o You can now use PROBUILD to build an executable with a remote
gateway configurable element. For example, if you need to
access a remote Oracle database, just select your networking
protocols and REMOTE ORACLE GATEWAY at the CONFIGURABLE
ELEMENTS screen.
o If you generate a load script using probuild you get the following
warnings:
ld default.ld 9 warning: absolute symbol err_fp% being redefined
ld default.ld 10 warning: absolute symbol err_val% being redefined
ld default.ld 11 warning: absolute symbol errno being redefined
ld default.ld 12 warning: absolute symbol minbrk% being redefined
ld default.ld 13 warning: absolute symbol curbrk% being redefined
ld default.ld 14 warning: absolute symbol addr_unfl% being redefined
These can be ignored. Olivetti states that this a library
alignment problem.
o Connecting Databases
--------------------
You must use the -Nv 12 startup option to connect a 6.2G
or above client to a Version 5 or 6.2A-6.2G PROGRESS server.
o Multi-Volume Databases - prostrct add
-------------------------------------
If you define a variable-length extent and then use the
"prostrct add" command to add another variable length
extent, the command does not work correctly. It should
convert the previous variable-length to a fixed-length
extent, but it does not.
To workaround this problem, do not use the "prostrct add"
command. Instead, create a new structure file (.st).
Define all of the extents you want to use, including any
new extents. Create a new void multi-volume database and
use the "procopy" command (or the "probkup" and "prorest"
commands) to copy the old database to the new one.
o Prorest Utility
---------------
Restoring an incremental backup out of sequence will
cause you to lose data. For example, if you restore
incremental 2, then restore incremental 1, you will lose
the data restored from incremental 2. You receive a
message telling you that the tapes are out of sequence,
but you are not warned about the data loss.
o ORACLE and Rdb Gateways
-----------------------
From PROGRESS Version 6.2G on, ORACLE and Rdb gateways
only use one index-cursor per buffer. (Prior to Version
6.2G, there was one index cursor for each different WHERE
clause.) This change enables the Next option in the
RESULTS Query Module to work with these gateways.
As a result, you cannot use code similar to the
following:
FOR EACH cust WHERE name BEGINS "a":
FOR EACH cust WHERE cust-num > 1: ...
END.
END.
This type of code produces a "No nested FOR EACH" error
message.
Instead, define a buffer for each inner FOR EACH loop.
For example, you can use code similar to the following:
DEFINE BUFFER cust-buf FOR cust.
FOR EACH cust WHERE name BEGINS "a":
FOR EACH cust-buf WHERE cust-num > 1: ...
END.
END.
o RESULTS with ORACLE and Rdb Gateways
------------------------------------
To run RESULTS for Version 6 with an ORACLE or Rdb
gateway, the gateway must be Version 6.2G or later.
o RMS GATEWAY
-----------
There is an intermittent problem in which you may
receive the error:
RMS FIND ERROR, Completion Status Code 0x0185A4 (1542)
One example in which you can receive this error is:
FOR EACH customer: DISPLAY customer. END.
However, if you do:
FOR EACH state: DISPLAY state. END.
you will not receive this error.
