This document describes how to set up and install Natural 6.3 on an OpenVMS platform. The following topics are covered:
The following topics are covered below:
See also Supported Operating Systems in the Release Notes.
The memory space required by Natural largely depends on the number of users.
The memory space per user is determined by the settings in the
parameter file NATPARM, especially by the values of profile
parameters such as USIZE and SSIZE.
In addition to the user-specific memory, memory is required for the buffer pool, which is shared among all users.
The space required on disk will be checked by the PCSI utility during the installation.
Approximately 350 MB of hard-disk space is required for Natural, another 18 MB for Natural Security, and another 7 MB for Natural Development Server.
The following product is required for installing Natural for OpenVMS:
Sagbase (GBA) Version 1.3 .
Natural 6.3 requires:
EntireX Broker Stub Version 8 to access a remote EntireX Broker (necessary if RPC is used).
Natural 6.3 includes interfaces to:
Adabas Version 6 (necessary if Natural Security, Natural Command Processor or Natural Development Server is used).
The Natural distribution kit on the installation medium contains the installation files for OpenVMS. An example of the directory hierarchy on the installation medium is shown in the section Directory Structure of the Installation Medium.
Please note that the license key file is not contained on this installation medium. It is delivered separately in your product package. If this is not the case, it can be obtained from Software AG.
This section contains important information on the necessary activities before installing Natural on an OpenVMS platform.
The following topics are covered below:
Please note the following before you start the Natural installation:
Software AG recommends some common steps for the installation of Software AG products on OpenVMS. See Installing and Setting Up Software AG Products on OpenVMS for a detailed description.
Before you start the installation, back up your current product version.
During the installation, you need a valid license key file.
Ensure that prerequisite software is installed.
The following UAF (User Authorization File) and SYSGEN parameters should have at least the following values for each Natural user:
| Parameter | Function | Minimum Value | Utility |
|---|---|---|---|
FILLM |
File limit | 100 | UAF |
TQCNT |
Timer queue elements | 10 | UAF |
ENQLM |
Lock queue entry limit | 1000 | UAF |
BYTLM |
Byte limit | 30000 | UAF |
MAXBUF
|
Maximum size of buffered I/O transfer | 4096 | SYSGEN |
JTQUOTA |
Job table quota | 2048 | UAF |
PGFLQUO |
Page file quota | 50000 | UAF |
PROCSECTCNT |
Process section count | 70 | SYSGEN |
To install the recommended Natural images, the following system resources are required:
| Images for | GBLPAGES | GBLSECTIONS |
|---|---|---|
| Natural Nucleus | 10000 | 50 |
| Natural Buffer Pool | 8000 | 1 |
To install the Natural images and to create the Natural buffer pool,
the following system privileges are required: CMKRNL,
SYSNAM, SYSPRV, PRMGBL,
SYSGBL, BYPASS.
The process privilege TMPMBX is required before Natural
can be used.
In a cluster environment, you must install Natural on each node on which it is to be used.
Depending on the Sagbase installation, the initial Natural installation within a cluster will choose either the common or the specific root directory. Each node must first be prepared by installing Sagbase. The installation procedure checks for an existing Natural installation in the cluster.
Subsequent installations consist of the following steps:
Checking whether or not system parameters have correct values.
Modifying NATBPENV_<nodename>.COM according to the parameters specified.
Modifying the startup component database if
STARTUP_NAT<v>.COM was
found in SYS$STARTUP.
Executing the command procedure STARTUP_NAT<v>.COM.
Note:
<v> in the above file name stands
for the first digit of the Natural version number.
You can use more than one Natural version on your system. Image names contain the current version number, and the command procedure LOGIN.COM is downward compatible.
When LOGIN.COM is called, the parameter
P1 should be set to the value of the full version number
of the used Natural version. For example, @SAG$ROOT:[NATURAL]LOGIN
6340.
If another version is to be used in the job environment of a specific
user, the UAF parameter JTQUOTA must be set to 2048.
If you have already installed Natural system-wide by executing
STARTUP_NAT<v>.COM, the
value of the parameter P1 was set to the value of the
installed Natural version.
You can now activate another version of Natural in a job environment by
executing
STARTUP_NAT<v>.COM with
the parameter P1 set to a different value of an existing
Natural version.
Natural will be installed in the SAG$ROOT:[NATURAL.V<version>] directory.
The Natural logicals are to be found in a version-specific name table called Natural_C$V<version>_LOGICAL_NAMES.
The installation procedure PSCI automatically performs the following steps when used to install Natural:
Checks whether the prerequisite version of the operating system is running.
Temporarily sets the privileges (BYPASS,
CMKRNL, SYSNAM).
Checks whether Sagbase (GBA) is installed.
Sets the owner of the SAG$ROOT directory to all installed product directories and files.
Checks whether system parameters have correct values.
Registers the product Sagbase to PCSI, if required.
Calculates and verifies the disk space needed for installation on both the work-directory device and the installation device.
Invokes the Natural suite installation.
Creates Natural directories, if necessary.
Moves all files and images to the appropriate directories.
Sets protections for files and directories.
The Natural product installation in the Natural product suite asks whether you want to copy STARTUP_NAT<v>.COM into the SAG$ROOT:[NATURAL] directory or the SYS$STARTUP directory.
Note:
If you want Natural to be loaded and activated automatically at
every booting, specify the option that the
STARTUP_NAT<v>.COM shall
be moved to SYS$STARTUP during the PCSI installation. An
entry in the system startup database will then automatically be generated. When
rebooting,
STARTUP_NAT<v>.COM will
then be invoked with the most current Natural version number as parameters
P1 and P2 will be set to
"BP". For more information, see
Changing a Process
Environment with
STARTUP_NAT<v>.COM.
The Natural product installation in the Natural product suite asks whether you want to modify the system startup database (only if the directory SYS$STARTUP was selected to contain STARTUP_NAT<v>.COM).
Creates the patch level file in the version subdirectory of the Natural directory (V<version>).
Note:
Patch level files are for internal use and should not be modified
or deleted. They are used for other installations.
Inserts the node-specific buffer pool section into the local configuration file.
Asks for the location of the buffer pool section file.
Creates the buffer pool start procedure NATBPENV_<nodename>.COM.
Note:
For more information, see Activating the Natural Buffer
Pool.
Executes STARTUP_NAT<v>.COM for the new Natural version.
Verifies the Natural installation.
The Natural suite installation invokes the installation of other products in the suite such as Natural Security or Natural Development Server.
Before you start installing Natural using the PCSI procedure, perform the necessary steps as described in Installing and Setting Up Software AG Products on OpenVMS.
You started the installation using the command procedure SETUP.COM located on the installation medium to install Natural in the OpenVMS environment.
SETUP.COM copies the Natural PSC file from the installation medium to the SAG$ROOT:[SAGKITS] directory and starts the Natural suite installation of the Polycenter Software Installation utility (PCSI). The suite installation automatically invokes the single product PCSI installations for Natural, Natural Security and Natural Development Server. During the installation procedure, a number of general information messages are displayed. Read all messages carefully and follow any advice they may provide.
If you have interrupted the SETUP.COM procedure after it has copied the product kits from the installation medium to the SAG$ROOT:[SAGKITS] directory, you can also start the Natural suite installation by entering the following:
product install NAT_6340_SUITE /destin=sag$root:[000000] /OPTIONS=NOVALIDATE
After the Natural suite is started, you will be informed:
The following product has been selected: SAG I64VMS NAT_6340_SUITE V6.34-PL0 Platform (product suite) Do you want to continue? [YES]
Enter "YES" to continue the installation.
Configuration phase starting ... You will be asked to choose options, if any, for each selected product and for any products that may be installed to satisfy software dependency requirements. SAG I64VMS NAT_6340_SUITE V6.34-PL0: NAT-suite for OpenVMS/Itanium Do you want the defaults for all options? [YES]
Enter "NO" if you want to set the options for single product installations.
Do you want to install NAT<version>? [YES]
Enter "YES" to continue with the Natural PCSI installation.
When you are asked whether you want to use the defaults for all options, enter "NO". You can then modify the following options (the recommended actions are given below):
Enter "YES".
Press RETURN to accept the default: the startup file is moved to the SYS$STARTUP directory and an entry is made in the startup database. Software AG recommends running the STARTUP_NAT<v>.COM procedure during system startup.
If you enter "NO", the startup file will be moved to the directory SAG$ROOT:[NATURAL].
Only shown when you used the default value for the previous question.
Press RETURN to generate entries in the system startup database in order to execute the procedure automatically during system startup.
An entry of the following form will be generated:
| Phase | Mode | File |
|---|---|---|
| LPBETA | DIRECT | STARTUP_NAT<v>.COM |
If you want to run the startup file during the installation, enter "YES".
If you enter "NO", you have to start the startup file manually after the product suite installation.
If you want to run the Natural buffer pool after the installation, enter "YES". The prerequisite for this is that you have also entered "YES" for the option Run STARTUP_NAT<v>.COM after successful installation?.
Not shown when Natural is installed with the suite installation.
If you enter "YES", the procedure now installs Natural to the destination directory.
If you enter "NO", you can review and change your options.
If you are installing Natural with the Natural suite installation, you are asked whether you want to install other products included in the suite. After the PCSI installation of the products in the suite is finished, the post-installation steps described in the above options are performed. Answer the questions (such as the location of the buffer pool) asked by the post-installation procedures. You will be informed whether the post-installation steps were successful.
After the successful installation of the suite, you are informed about the installed products, for example:
The following products have been installed:
SAG I64VMS NAT_6340 V6.34-PL0 Layered Product
A message appears during the installation process, informing you that the product "SAG I64VMS NAT_<version> V<v.rs>-PL<p> Layered Product" has been selected, and asks whether you want to continue.
When you answer "YES", the installation procedure checks whether the product Sagbase (product code GBA) has already been installed and registered with the PCSI utility. If Sagbase has been installed but not yet registered, you will be asked to do so. Register by following the instructions on the screen. If the Sagbase software has not been found on your system the installation aborts. In this case, follow the steps in Installing Sagbase on OpenVMS.
Information on the product license key is shown. Check whether the license key file is available on SYS$LOGIN of the installing user. Without a proper license key file, the installation will abort.
The procedure inserts the node-specific buffer pool section into the local configuration file.
The information about the global section file for the Natural buffer pool file is displayed. You have the choice to place the section file into the NATETC directory or to another location.
If you answered Run
STARTUP_NAT<v>.COM after successful
installation with "YES", the procedure
continues by executing
STARTUP_NAT<v>.COM with
parameters P1 (version number) and
P2 ("BP") to define the
logical names required by Natural. The Natural images will not be installed.
See the section Changing a Process Environment
with STARTUP_NAT<v>.COM
below.
The following topics are covered below:
To verify the product entry in the PCSI database enter:
PRODUCT SHOW PRODUCT NAT_<version>
After the Natural suite installation (PCSI), the following post-installation steps for Natural have to be performed.
Go to the following directory:
SET DEF SAG$ROOT:[NATURAL.V<version>.INSTALL]
In this directory, execute the following procedure:
@SAGINST_NAT.COM
The Installation Procedure screen appears. It offers the following functions:
1 - Load Natural modules 2 - Check logfile of inpl procedure 3 - Specify Adabas DBID for SYSNCP 4 - Create SYSNCP file
To complete the installation, first execute function 1, then execute function 2. If you want to use the Natural command processor, execute functions 3 and 4.
Your installation is now complete.
To set the Natural symbols, run the LOGIN.COM command procedure:
SET DEF SAG$ROOT:[NATURAL] @LOGIN.COM <version>
for example, @LOGIN.COM 6340.
To invoke Natural, enter "NAT63".
During the Natural installation with PCSI as described above, the command procedure STARTUP_NAT<v>.COM was executed for the environment, if you answered Run STARTUP_NAT<v>.COM after successful installation? with "YES". However, if you want to change a user-specific environment, you can use STARTUP_NAT<v>.COM again, but you specify different parameters. These parameters are:
| Parameter | Description |
|---|---|
| <p1> | Natural version. |
| <p2> | "BP" if you want to activate the Natural buffer pool, or "NOBP" if you do not want to activate it. |
| <p3> | "INST" if you want to install the Natural images, or nothing if you do not want to install them. |
Note:
If you want to install the Natural images, you must have the
privileges SETPRV, CMKRNL, SYSNAM or
SYSPRV.
Enter the following command to start STARTUP_NAT<v>.COM:
@STARTUP_NAT<v> <p1> <p2> <p3>
For example:
@STARTUP_NAT6 6340 BP INST
To activate the Natural buffer pool, you execute the command procedure
STARTUP_NAT<v>.COM with
parameter P2 set to "BP" as
in the following example:
@STARTUP_NAT<v>.COM <version> BP
