ILL2: SLNP server cannot be started

• Article Type: General
• Product: Aleph
• Product Version: 18.01

Description:
I have activated ILL2 (switch ILL-MODE in alephe/tab/tab100 set to 2).
But when I now try to start the SLNP server via util w/3/7/5, nothing happens.
I don't even get an error message.

Resolution:
When starting the SLNP server manually, the following error message is displayed:

dlib xxx40
ap
csh -f slnp_server 5441 &


--> error message "Directory stack not that deep."

The explanation for this error message is as follows:

The script for starting the SLNP server uses the "cat" command to determine the ILL-MODE:

cat $alephe_tab/tab100 | grep ILL-MODE= | cut -c10-20"

If now e.g. the old entry "ILL-MODE=1" in alephe_tab/tab100 has only been commented out but still exists in the table, in addition to an active entry "ILL-MODE=2", the "cat" command produces an unusable result:

-alephe_tab/tab100

!ILL-MODE=1 << old entry is commented out but still exists
ILL-MODE=2

--> "cat $alephe_tab/tab100 | grep ILL-MODE= | cut -c10-20" produces the following result:

=1
2

As a result, the SLNP start script runs into the error described above.

After removing the line "!ILL-MODE=1" from alephe/tab/tab100, the SLNP server could successfully started via util w/3/7/5.
