frequently without greatly affecting processor utilization. The interval you
choose should be based on your own situation, and the size of your
address books.
Regardless of what the refresh interval is set to, if there have been no
changes to the system distribution directory since the last time the address
book cache was refreshed, a refresh is not performed. The refresh interval
specifies how often the POP server checks to see if the cache is still
current; if it is not current, it is refreshed.
If you plan to use only the Client Access MAPI-based clients, consider setting
the Allow standard connection (ALWSTDCNN)parameter of CHGPOPA to *NO
in order to save resources. This parameter defaults to *YES, which specifies the
normal socket interface used by standard clients.
Removing POP Mail Users from the System
If you sign on to the client, the best way to remove users is to:
1. Sign on
2. Remove the user from the system distribution directory (this prevents any more
mail from being delivered)
3. Connect a mail client as the user to be removed and receive any mail left in the
mailbox
4. Delete the user’s profile from the AS/400 system
Setting the Number of SNA Servers
The number of servers (NBRSVR) parameter of the CHGPOPAcommand
determines how many POP server jobs to start when the POP server is started. The
number of SNA servers is not affected by this parameter.
The number of SNA servers is determined by prestart job configuration, and set on
the Change Prestart Job Entry (CHGPJE) command. Youcan accept the defaults
on this command, or change the number of SNA servers. Tochange the number of
SNA servers, use these parameter values:
vFor the qualified subsystem name (SBSD), specify QSYSWRK.
vFor the program name (PGM), specify library QTCP and program name
QTMMSRVR.
Use these parameters to set the number of SNA servers:
vINLJOBS — the initial number of prestart jobs to start for the subsystem
vTHRESHOLD — the minimum number of prestart jobs that must be available
before additional prestart jobs are started
vADLJOBS — the additional number of prestart jobs to start when the number of
prestart jobs drops below the value of the THRESHOLD parameter
vMAXJOBS — the maximum number of prestart jobs that can be active at the
same time for this prestart entry.
Stop and restart the POP servers for any changes to take effect.
