pb after a virtual procedure

[maurice Libes]

 hello
we have made a wrong operation which had for consequences that we can not see anymore  the procedures for a given service

we have created a "virtual procedure" which code is probably wrong
and now we can not see  anymore the "normal" procedure of the same service

the error message is :

Can't instantiate abstract class istvp with abstract methods execute
Status response: OK
Resource: waGetlist
Method: GET
Path /istsos/services/htmnet/procedures/operations/getlist

thanks if you can give us a solution which allows to see again the procedures

Hi Maurice,

Please take a look at the apache error log (/var/log/apache2/error.log), there you should be able to see what's wrong with your virtual procedure.

Just open a terminal and launch this command:

tail -f /var/log/apache2/error.log

Then on another terminal window restart apache:

sudo service apache2 restart

You should be able to see the python error.

Otherwise you can remove the misconfigured virtual procedure by hand. First make a backup of the postgresql database and the /services folder.

Then connect to your postgresql db (via psql or pgadmin or else) and delete the virtual procedure from the "SCHEMA.procedures" table and

delete the files virtual procedure folder (/INSTALLATION_PATH/istsos/services/sos/virtual/PROCEDURE_NAME).

Best regards

Milan

thanks to your answer Milan

here is the error log, when I click on the "procedures" menu of the service which has the virtual procedure

maybe it tells something to you ?

I will try to remove the misconfigured virtual procedure by hand as you suggest

thanks

ok thanks I have deleted the virtual procedure from the "SCHEMA.procedures" table

and that solved the problem

istsos=# delete from htmnet.procedures where name_prc='Virtual_PortCros' ;
DELETE 1

It remains to be seen what caused the error when we created a virtual procedure

thanks

Maurice
