ClearPath OS 2200 Series Release 13.2 Software Planning and ...

Open Programming Environment (OPE)
OPE Level 4R1H or Higher
Migration and Compatibility Considerations
The UCARD parameter is no longer required, but it is included for backward
compatibility. If there is a UCARD entry, that OS 2200 user-id/password is used for the
background run that supports the OPE communications and chronological tasks (CRON
RUN). Otherwise, the user-id of the user initiating the OPE boot is used for the
background run. The user-id/password can contain characters from the set (A through Z,
0 through 9, /, and *). This user-id must have real-time capabilities.
The UCARD changes also affect user commands demand(1) and submit(1). With
demand and submit, the user-id of the current run is used when a UCARD is not present.
Submitl and demandl no longer require that the user-id/password be present in the
submit and demand files as long as the first line in the file starts with @run. Consult the
OPE online man pages for more details.
Mail Considerations
Considerations for setting up Mail and Domain Name Resolver in OPE are as follows:
Mail Setup
The mail system is a port of UnixWare mail. Setting up mail involves the following steps:
1. Before upgrading to OPE level 4R1H or higher, run
/usr/lib/mail/surrcmd/smtpsched
This processes any messages queued in the SMTP mail queue /var/spool/smtpq.
In UnixWare mail, the mail queue is /var/spool/mailq and the
/usr/lib/mail/surrcmd/smtpsched program no longer exists.
2. After replacing the /etc/passwd, /etc/shadow, and /etc/group files with your saved
copies, modify them so there is a mail user-id and the home directory for smtp is
/var/spool/mailq and not /var/spool/smtpq. Make the following changes:
• /etc/passwd:
Replace the lines for uucp, nuucp, and smtp as follows:
uucp:x:5:5:0000-uucp(0000):/usr/lib/uucp:
nuucp:x:10:10:0000-uucp(0000):/usr/spool/uucppublic:/usr/lib/uucp/uucico
smtp:x:55:6:SMTP Processes:/var/spool/mailq:/usr/bin/sh
Add the following line for the mail uid immediately after the line for the uucp uid:
mail:x:6:6:Mail Processes:/etc/mail:
