2087.0. "Segmentation fault (core dumped)" by C6BON::BLAT (cluster) Mon May 26 1997 12:13

        Hello,
        I have 2 systems DECsafe running UNIX V3.2G and ASE130.
        ASE has been successfully installed and configured,
        2 Disk services have been added , but I cannot add the
        start and stop script because when ASE wants to delete a
        service to recreate it during the add script option,
        the delete service fails,
        and if I try to delete a service with the menu , I have a
        segmentation fault.
	(the localhost is OK )

        Thanks in advance for any help./Patrick

                Service Configuration

    a)  Add a new service
    m)  Modify a service
    d)  Delete a service
    s)  Display the status of a service

    x)  Exit to Managing ASE Services    ?)  Help

Enter your choice [x]: d

        Deleting a Service

Select the service you want to delete:

    1)  louxor on naples
    2)  alexas on naples

    x)  Exit to Service Configuration    ?)  Help

A segmentation fault is a software bug.  I looked at the README file
for the ASE 1.3 patches and I didn't see any patch that matched this
set of circumstances.  I think it is time for you to contact the
software support organization.

You will find that it is much much easier to give ASE only a 
'dummy' script whose job is to call your real start and stop scripts. This lets you do a 
lot of the debugging without involving ASE and also gives you a nice break point to 
escape from the pickle that you have gotten into.

I always have my real start/stop script do a check for a file called "DoNothing" which, 
if found, will indicate that the real script should simply exit. With "DoNothing" in 
place I can check out all the 'pure' ASE issues. THen I can put the service 'online' and 
then remove DoNothing and then directly call my start/stop script for debugging them 
without involving ASE at all. Once I'm confident in both the ASE setup and the scripts 
then I can go ahead and do full testing.

good luck.
