database - error accessing oracleDB with python -


i used docker run virtual oracle db server on localmachine(host).

it works when use in on shell(bash).

however want make access python interface.

cx_oracle(python interface oracle) installed,

but not accessed on python code(jupyter notebook). code simple below

import cx_oracle con = cx_oracle.connect("system/oracle@localhost:8080")

error code:

databaseerror                             traceback (most recent call last) <ipython-input-8-681e47c38e7c> in <module>() ----> 1 con = cx_oracle.connect("system/oracle@localhost:8080")  databaseerror: ora-12537:

i'm not sure can use cx_oracle.connect port that. can check data source name ( dsn ).

first, try connecting without :8080. if doesn't work, try below.

go python interactive mode command line. python -i

import cx_oracle

dsn = cx_oracle.makedsn( 'localhost', '8080' )

if don't find that, check out burleson. site helpful ora issues.

http://www.dba-oracle.com/t_ora_12537_tns_error.htm

and of course, assume have doc:

http://cx-oracle.readthedocs.io/en/latest/module.html?highlight=connect

also, assuming following guide, might want link it's url in comments or in original post.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
