I am trying to open file I made from example code in a web console
code:
https://h2database.com/html/mvstore.html#example_code
running web console https://h2database.com/html/tutorial.html#tutorial_starting_h2_console
error in the web console:
Database "/correct/path/to/file" not found, either pre-create it or allow remote database creation (not recommended in secure environments) [90149-212] 90149/90149 (Help)

The file does exist and I can read it via Java code, but not with web console.

getting below error while starting the database:-
startup
ORA-01078: failure in processing system parameters
ORA-01565: error in identifying file '+DATA/mis/PARAMETERFILE/spfile.276.967375255'
ORA-17503: ksfdopn:10 Failed to open file +DATA/mis/PARAMETERFILE/spfile.276.967375255
ORA-04031: unable to allocate 56 bytes of shared memory ("shared pool","unknown object","KKSSP^24","kglseshtSegs")
Your database cannot find the SPFILE (newer init.ora) within ASM with the actual system parameters or has no permissions to access it.
Either your Grid Infrastructure stack or the dbs/spfile.ora is pointing to the wrong file.
To find out what the grid infrastructure stack is using, run "srvctl" which should display the parameterfile name the database should be using
srvctl config database -d <dbname>
...
Spfile: +DATA/<dbname>/PARAMETERFILE/spfile.269.1066152225
...
Then check (as the grid user), if the file indeed is not visible (by using asmcmd):
asmcmd
ASMCMD> ls +DATA/<dbname>/PARAMETERFILE/
spfile.269.1066152225
If the name is different, then you got the issue... (and you have to point to the correct file).
If the name is correct, then it could be wrong permissions on the oracle executable(s) (check My Oracle Support):
RAC Database Can't Start: ORA-01565, ORA-17503: ksfdopn:10 Failed to open file +DATA/BPBL/spfileBPBL.ora (Doc ID 2316088.1)
Configuration
My Spring Boot/Liquibase specifications & configuration is as per this question.
Issue
Everything goes well in my local environment with embedded Tomcat. When i migrate the war file to IBM WebSphere 8.5.5.15, i see this warning:

I have checked and the jar file is not there at the location that it is looking for it.
Question
It's only a warning, everything else is working as expected, should i be concerned about this warning?
I have created a simple HTML page to control the movement of a simulated Gazebo Turtlebot using roslaunch rosbridge_server rosbridge_websocket.launch following this tutorial.
However, in the Web Console of the HTML page (F12) it shows the error "Firefox cant establish a connection to the server at ws://localhost:9090/." I am using the default rosbridge for the websocket(9090). In the Terminal I am also receiving the errors:
[-] failing WebSocket opening handshake ('WebSocket connection denied: origin 'null' not allowed')
[-] dropping connection to peer tcp4:127.0.0.1:41290 with abort=False: WebSocket connection denied: origin 'null' not allowed.
Does anyone have any suggestions on how I can fix this?
Given that you have followed the ROS tutorial and have created an HTML file as shown in Ros Bridge tutorial then you have to run:
runcore
rosrun rospy_tutorials add_two_ints_server
roslaunch rosbridge_server rosbridge_websocket.launch
Now that you have these up and running, you need to serve the html/javascript file (e.g. simple.html) and start the services etc. For example, you can serve the simple.html by using a SimpleHTTPServer, see below an example (e.g. simplehttpserver_test.py):
#!/usr/bin/env python
import SimpleHTTPServer
import SocketServer
class MyRequestHandler(SimpleHTTPServer.SimpleHTTPRequestHandler):
def do_GET(self):
if self.path == '/':
self.path = '/simple.html'
return SimpleHTTPServer.SimpleHTTPRequestHandler.do_GET(self)
Handler = MyRequestHandler
server = SocketServer.TCPServer(('127.0.0.1', 9089), Handler)
server.serve_forever()
Once you run the simplehttpserver_test.py you can open the browser on 127.0.0.1:9089 and you should be able to have it working.
Note that SimpleHTTPServer serves files from the current directory and below, directly mapping the directory structure to HTTP requests, which means that the simple.html should be in the same (or below) directory as the simplehttpserver_test.py. Last, the port for the simplehttpserver_test.py should differ from the one used for the Rosbridge WebSocket server (e.g. default is 9090).
My Oracle Reports server 10g wasn't working properly while interacting through Oracle Forms 10g with following error:
REP-52266: The in-process Reports Server rep_user failed to start.oracle.reports.RWException: IDL:oracle/reports/RWException:1.0
Then I got to know about below solution from stack-overflow
Search the file rwnetwork.conf
Change the lines
From
<multicast channel="228.5.6.7" port="14021" timeout="1000" retry="5"/>
<!--namingService name="Cos" host="127.0.0.1" port="14021"/-->
To
<!--multicast channel="228.5.6.7" port="14021" timeout="1000" retry="5"/-->
<namingService name="Cos" host="127.0.0.1" port="14021"/>
Start thenamingservice : namingservice 14021
After trying all three steps successfully now I am in trouble with following error:
REP-52266: The in-process Reports Server rep_user failed to start.oracle.reports.RWException:
IDL:oracle/reports/RWException:1.0
I have found the solution for
REP-52266: The in-process Reports Server rep_user failed to
start.oracle.reports.RWException: IDL:oracle/reports/RWException:1.0
simply restart you Server and make sure your OC4J is not start yet
(if you have your OC4J on startup then first stop that then restart
your server)
now before you open any thing go to
C:\DevSuiteHome_1\reports\server\
Now delete the file placed here "your_server_name.DAT" File
After this now start your services of OC4J and run the Report
Hope it will work for you too
Thanks!

I have a Ruby script (non-Rails) that connects to a SQL Server database. When run from the command line, it runs fine. When executed via an http request, it generates an error, specifically when opening the DB connection. Something about the combination of the http/SQL methods is failing.
I'm running the script on a machine with: Windows 7 Ultimate (64-bit), Ruby 1.9.3p125, Apache 2.2.11. The database is SQL Server 10.0.4000, hosted on a separate (corporate, internal) server.
The script looks something like this:
#!/Ruby193/bin/ruby
require 'win32ole'
...
$qadb = nil
begin
$qadb = SqlServer.new('192.168.100.249', 'qauser', 'password')
$qadb.open('qadb')
rescue
logRegression("Rescued: Unable to access QADB: #{$!}")
end
The SqlServer class is based on David Mullet's code, found at http://rubyonwindows.blogspot.com/2007/03/ruby-ado-and-sqlserver.html (not copied here for brevity).
From the command line, the DB opens fine and I get an expected result from the script. When I call the script via my internal server (http://qatools/getTask.rb) I get the following error in my log file:
Rescued: Unable to access QADB: failed to create WIN32OLE object from `ADODB.Connection'
HRESULT error code:0x8007007e
The specified module could not be found.
I've considered that I might be missing a DLL. Other research led me to ntwdblib.dll -- I tried downloading a copy and placing it in various folders. I've also considered that I might be facing an Apache configuration issue and/or a security/permissions issue but I haven't found any solutions for those that seem to fit my specific problem.
Any ideas?
