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)
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:
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
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).
