System Testing

You can perform the following steps to determine whether Natural Advanced Facilities functions correctly.

Start of instruction set To print a test report

In the appropriate logical printer, set the Disposition to K for testing.

Log on to the Natural system library SYSPOOL and execute the programs NTEST and SPPTEST. These programs contain WRITE (1) statements.

Or:
Create test reports with Function 42 described in the Natural Advanced Facilities documentation.

Start of instruction set To proceed if a test report cannot be printed

Check that the CICS printer status is IN SERVICE.
Use the CICS message switching transaction CMSG to route a message to the specified printer:
```
CMSG 'message',ROUTE=term-id,SEND
```
where term-id is the terminal identification of the CICS printer as specified in the TCT.
If Natural Security is installed, check whether logon error records (of the NATSPOOL spool server NATP) have been written to the Natural Security system file. The maintenance system for these error records can be invoked by entering ERROR in the command line of Natural Security.
Check that the standard Natural LOGON object has not been replaced. The NATSPOOL spool server NATP must be able to execute the SVPCIC01 module in the SYSPRINT library.

Also check whether the LOGON user exit causes the LOGON of the spool server to SYSPRINT to terminate.
Check that the catalog dates of the objects in SYSPRINT and SYSPOOL are identical to one another.
Check that the parameters for the spool server match the Natural Advanced Facilities environment. To do so, invoke MENU in the SYSPOOL library and check the CICS Options defined with Function 30.5 (see the Natural Advanced Facilities documentation).
Check that neither the external security (EXTSEC operand of CICS PCT) nor the security levels (TRANSEC operand of CICS PCT) are defined for the spool server NATP. This ensures that NATP can be initiated without security violations.
Check the TCT and VTAM definitions (see Step 10: Define Natural Advanced Facilities for Natural Security, Step 13: Define Natural Advanced Facilities for VTAM/SNA and Step 14: Define Natural Advanced Facilities for VTAM/non-SNA in the section Installing Natural Advanced Facilities under CICS).
Allocate a screen device instead of a printer device to the Destination/Form pairing of the first logical printer, execute NTEST in the SYSPOOL library, and check for error messages on the screen.

On certain devices, the CICS abend ATNI may occur.

Since the Natural Security logon processing checks whether the device is a printer, this test is only possible if Natural Security is not installed.
Start the transaction CEDF for your terminal device and check whether the command EXEC CICS START (to start the spool server) is executed.
Start the transaction CEDF for your printer device (CEDF terminal ID of printer) and check which commands are executed.
Check the Natural Advanced Facilities messages on the system operator console and/or in the log file (the destination of messages is defined with Function 30.5 (see the Natural Advanced Facilities documentation).

Console messages sent by the spool server start with:
```
NAF SP-SERV:
```
Console messages sent by the terminal task start with:
```
NAF-
```
Obtain a NATSPOOL trace and check which Natural Advanced Facilities modules are called, which Adabas commands are executed, and which return codes are encountered.

NATSPOOL Trace using SYSRDC

Start of instruction set To obtain an online NATSPOOL trace by using the Natural SYSRDC utility

Start a Natural session with the following dynamic parameters:
```
RDCSIZE=100, TRACE=(NATAM08), ITRACE=ON
```
Log on to the SYSRDC library.
Execute the following command to select the internal trace type:
```
RDCSET N
```
Execute the following command to start the trace:
```
RDCSTART
```
Execute a program which creates a report, for example, NTEST in the SYSPOOL library.
Log on to the SYSRDC library.
Execute the following command to display the trace entries:
```
RDCDISP
```
You will now see when a NATSPOOL module begins (marked as BEG) and ends (marked as END) as well as its return code in decimal representation.

After the execution of an Adabas call (marked as ADA), you will see the command code, the first byte of the command ID and the return code in decimal representation.

For detailed information on the SYSRDC utility, see the Utilities documentation.
