Figure 1-45 REXEC server properties

Selecting a command processor

You can use the REXEC server command processing selection exit program

(QIBM_QTMX_SVR_SELECT) to select which command processor the REXEC server uses

to run the submitted command. (If you do not use an exit program, the REXEC server uses

the Control Language (QCAPCMD) processor.) The allowed command processors are:

򐂰 Control Language (QCAPCMD)

򐂰 Qshell interpreter

򐂰 Spawned path (a shell script or program object)

Tracing the REXEC server

The REXEC server can be traced by creating a data area. Note that running the REXEC

server with trace running may cause a significant performance impact.

To trace the REXEC server:

1. Create the data area using the following command:

CRTDTAARA DTAARA(QUSRSYS/QTMXRXCDBG) TYPE(*LGL) LEN(1)

2. Perform the REXEC operation that you want to trace.

3. Delete the data area using the following command:

DLTDTAARA DTAARA(QUSRSYS/QTMXRXCDBG)

The output from the trace will be placed in the default outq as specified by system value

QPRTDEV. The spooled file will be named QPSRVTRC.

Additional information related to configuring and using the REXEC server is available in the

Information Center.

1.4.24 SMTP

Simple Mail Transfer Protocol (SMTP) e-mail is the protocol that allows iSeries 400 to send

and receive e-mail. The SMTP protocol is essentially end-to-end delivery of mail from one

mail server to another. There is a direct connection between an SMTP sender (the client) and

the destination SMTP receiver (the server).

The SMTP client keeps the mail at the sender until it transmits and copies it successfully to

the SMTP receiver (server).

Chapter 1. Network 53

SMTP on iSeries 400 supports the distribution of notes, messages, and ASCII text

documents. SMTP can support formats other than plain text by using the Multipurpose

Internet Mail Extensions (MIME) protocol. The MIME protocol is the data format of the

message that SMTP sends.

A full discussion of SMTP integration into any network is beyond the scope of this redbook.

For information relating to SMTP configuration on your iSeries environment, please refer to

the Information Center.

To enable a basic configuration, select Properties from the context menu of the SNTP server.

The properties tabs are displayed as shown in Figure 1-46.

Figure 1-46 SMTP server properties

Most values throughout the tabs are automatically populated when you configure TCP/IP on

your iSeries system.

General tab settings

Mail Router: Enter the name of your organization’s mail router. The mail router name is the

system name where SMTP routes the mail if the e-mail is not local iSeries system.

If you are using the SNDDST command to send e-mail and the RCVDST command to receive

e-mail, and you are using SNADS addressing instead of internet addressing, select the

Automatically add remote users to system distribution directory check box.
