TITLE    : Howto increase the timeout of rembak
OS LEVEL : AIX 4.1.x and 4.2.x

----------------------------------------------------------------------------

In AIX 4.1.x and 4.2.x you cannot select a timeout value for rembak
when setting up a remote print queue. This means that the default
value of 90 seconds is used.

For the following problem detailed below, increasing the rembak timeout
from 90 seconds to 45 minutes stopped the printing problems :-


The remote printer stopping printing.
The AIX queue is in the "DOWN" state when viewed with lpstat.
An error messages appears on the console simular to the examples below :-

Message from queueing system:                                                   
rembak: (FATAL ERROR): 0781-244 File acknowledgement sent, but not received.    
rembak: errno = 4: A system call received an interrupt.

Message from queueing system:                                                   
/usr/lib/lpd/rembak -S printserver1 -P queue1 -N /usr/lib/lpd/bsdshort /var/spo
ol/qdaemon/t1BoAia <EOT>  

When the queue is enabled the print job that failed starts from the beginning
again.

To increase the rembak timeout :-

1, Stop all the users printing, ensure that no print job is printing or
   queued to be printed, check using lpstat
2, Stop the qdaemon subsystem using stopsrc -s qdaemon.
   You can check that qdaemon has stopped using lssrc -s qdaemon.
3, Edit the qdaemon configuration file by vi /etc/qconfig

   A typical rembak print queue looks like :-

textq:
        device = @nps
        up = TRUE
        host = nps
        s_statfilter = /usr/lib/lpd/attshort
        l_statfilter = /usr/lib/lpd/attlong
        rq = pr5
@nps:
        backend = /usr/lib/lpd/rembak

Amend the line that calls remback as a backend so that it looks like :-

        backend = /usr/lib/lpd/rembak -T X 

Where X is the number of minutes that you require the new timeout value to
be. 0 is the default value of 90 seconds and 32767 is the maximum number
allowed (22 days !).

4, Start the qdaemon subsystem using startsrc -s qdaemon.
