Copying Tapes for Distribution
When you run the job stream, replies for the tape devices will still be required at the
console. If an error occurs, SLTCOPY will write the cause of the error to the spoolfile, and the
job will abort. The following is an example job stream called COPYJOB used for copying tape
to tape:
!JOB COPYJOB, MANAGER.SYS,INSTALL
!COMMENT On the next two lines, 3 is the option (tape to tape)
!COMMENT and 2 is the number of tapes
!SLTCOPY
3
2

!EOJ
Overriding Defaults
Two options for SLTCOPY are provided to allow additional control over the utility. The
options are INFO=NOWAITIO and INFO=WAITIO. You only need to use these options if you
want to override the SLTCOPY defaults.
To override the defaults, you should be very familiar with MPE/iX I/O operations.
WAITIO causes SLTCOPY to wait to send the next buffer until it receives an acknowledgment
from the system that the last buffer has been written to tape. NOWAITIO tells SLTCOPY not
to wait for the acknowledgment before sending the next buffer. This option is useful (and is
the default) when creating multiple output tapes. It allows SLTCOPY to create multiple
tapes virtually simultaneously.
To override the defaults listed in Table E-1., you invoke SLTCOPY as follows.
If making one copy and wanting to use the NOWAITIO option, invoke SLTCOPY as follows:
:RUN SLTCOPY;INFO=“NOWAITIO”
You then respond 1 when SLTCOPY requests the number of copies.
If making multiple copies all at once and wanting to use the WAITIO option, invoke
SLTCOPY as follows:
:RUN SLTCOPY;INFO=“WAITIO”
You then specify the number of copies you want to make when SLTCOPY requests the
number of copies.
NOTE Remote file access is not permitted for output tapes if the NOWAITIO option is
in effect.
