I'm trying to set up Geoportal 1.2.4, running on Apache Tomcat 8.5.6, Postgres 9.0.6_1, JDK 6, and jdbc(postgresql-9.1-901.jdbc4.jar). I cannot log into the Geoportal, When I log in using admin details (),I
get this error
"A database communication error has occurred"
Checking the Apache logfiles, I see there's a severe error
I have tried a range of different entries in the config for the jdbc, but it always comes back to that error.
That is just my latest attempt. I have seen conflicting posts all over the net about exactly what the url should look like.
I checked the rest of the config files carefully, and the editing within them was minimal and probably has no play on the error.
If anyone could point out my mistake it would be appreciated.

For this project, I am using a prisma / Postgres database. I have made no changes to my code, and I have pulled a coworkers working version of the code to no avail. I am unable to do anything with the database, I cannot migrate, I cannot run mutations, and I cannot even open the psql console, as every command is met with
P1001: Can't reach database server at localhost:5432
Please make sure your database server is running at localhost:5432
I am not sure what I could have possibly done, I don't know enough about ports or even the contents of app.json well enough to have messed anything up. Now, no mutations can go through.
Interestingly enough, this all happened after I ran npx primsa migrate deploy on the deployed database which is on a EC2 VM from AWS. Since then, the native app associated with the database refuses to work, though it is worth nothing that the webapp connects to the deployed database just fine. This being said, nothing works locally, as the database / Port / Server don't exist anymore according to my machine, which makes no sense. I have no idea how to try to re-spin it, or why every single query / mutation from my Native App now ONLy returns Response not successful: Received status code 400 despite it having the same exact syntax it did when it worked, as well as the WebApp having the same syntax and server (ExpressJS). Does anyone have any ideas what could be causing this?
The error code 400 refers to a bad request coming from the client: too large request, malformed syntax, invalid request message framing, etc.
First step: make sure that your database server is indeed running. Try connecting to it with other SQL Clients or Libraries. Sometimes Prisma is just being difficult.
Second thing: are you hosting the database on the local server? I can assume you are because of the localhost. Make sure no other programs are using this port or maybe waiting for it.
Sorry if this doesn't help. Good luck!
We have been running a service using NestJS and TypeORM on fully managed CloudRun without issues for several months. Yesterday PM we started getting Improper path /cloudsql/{SQL_CONNECTION_NAME} to connect to Postgres Cloud SQL instance "{SQL_CONNECTION_NAME}" errors in our logs.
We didn't make any server/SQL changes around this timestamp. Currently there is no impact to the service so we are not sure if this is a serious issue.
This error is not from our code, and our third party modules shouldn't know if we use Cloud SQL, so I have no idea where this errors come from.
My assumption is Cloud SQL Proxy or any SQL client used in Cloud Run is making this error. We use --add-cloudsql-instances flag when deploying with "gcloud run deploy" CLI command.
Link to the issue here
This log was recently added in the Cloud Run data path to provide more context for debugging CloudSQL connectivity issues. However, the original logic was overly aggressive, emitting this message even for properly working CloudSQL connections. Your application is working correctly and should not receive this warning.
Thank you for reporting this issue. The fix is ready and should roll out soon. You should not see this message anymore after the fix is out.
I am using ORACLE database in a windows environment and running a JSP/servlet web application in tomcat. After I do some operations with the application it gives me the following error.
ORA-12518, TNS: listener could not hand off client connection
can any one help me to identify the reason for this problem and propose me a solution?
The solution to this question is to increase the number of processes :
1. Open command prompt
2. sqlplus / as sysdba; //login sysdba user
3. startup force;
4. show parameter processes; // This shows 150(some default) processes allocated, then increase the count to 800
5. alter system set processes=800 scope=spfile;
As Tried and tested.
In my case I found that it is because I haven't closed the database connections properly in my application. Too many connections are open and Oracle can not make more connections. This is a resource limitation. Later when I check with oracle forum I could see some reasons that have mentioned there about this problem. Some of them are.
In most cases this happens due to a network problem.
Your server is probably running out of memory and need to swap memory to disk.One cause can be an Oracle process consuming too much memory.
if it is the second one, please verify large_pool_size or check dispatcher were enough for all connection.
You can refer bellow link for further details.

I ran across the same problem, in my case it was a new install of the Oracle client on a new desktop that was giving the error, other clients were working so I knew it wouldn't be a fix to the database configuration. tnsping worked properly but sqlplus failed with the ora-12518 listener error.
I had the tnsnames.ora entry with a SID instead of a service_name, then once I fixed that, still the same error and found I had the wrong service_name as well. Once I fixed that, the error went away.
If from one day to another the issue shows for no apparent reasons, add these following lines at the bottom of the listner.ora file. If your oracle_home environment variable is set like this:
(ORACLE_HOME = C:\oracle11\app\oracle\product\11.2.0\server)
The lines to add are:
ADR_BASE_LISTENER = C:\oracle11\app\oracle\
DIRECT_HANDOFF_TTC_LISTENER=OFF
I had the same problem when executing queries in my application. I'm using Oracle client with Ruby on Rails.
The problem started when I accidentally started several connections with the DB and didn't close them.
When I fixed this, everything started to work fine again.
Hope this helps another one with the same problem.
I experienced the same error after upgrading to Windows 10. I solved it by starting services for Oracle which are stopped.
Start all the services as shown in the following image:
I had the same issue. After restarting all Oracle services it worked again.
same problem encountered for me.
And from oracle server listener log, can see more information.
and I found that the SERVICE_NAME is not match the tnsnames.ora configured Service name. so I changed the application's data source configuration from SID value to Service_NAME value and it fixed.

I had the same issue in real time application and the issue gone by itself next day. upon checking, it was found that server ran out of memory due to additional processes running.
So in my case, the reason was server run out of memory
first of all
check the listener log
check the show parameter processes vs select count(*) from v$processes;
increase the process, it may require SGA increase

I'm trying to get a Play (2.1) app with ReactiveMongo (0.9) working on the app's test server. However, when our application is run on my dev box, is able to store image metadata just fine, even pointing to the mongo 2.2 install on the mongo test server. Even ran it with "play stage", then run directly with java 1.6.0. However, run the same way, also with Java 1.6.0 on the test server, the app continuously logs this error:
r.c.a.MongoDBSystem - The entire node set is unreachable, is there a network problem?
r.c.a.MongoDBSystem - The entire node set is unreachable, is there a network problem?
r.c.a.MongoDBSystem - The entire node set is unreachable, is there a network problem?
And not just during initialization... it repeats indefinitely. I've seen this error mentioned elsewhere, but I don't think those solutions apply to this. From the app's test server, I'm able to telnet to port 27017 on the mongo test server successfully. I see both my local install and the test server install of the app log that it's using the same mongodb url.
So based on what I said, I believe I can eliminate:
Blocked port
Mongo server down
Pointing to wrong mongo server
Mongo version mismatch
Java version mismatch
I'm going through the reactivemongo source but it seems the error is spewed when the MongoChannels are not set as authenticating or ready state (usable). I'm planning to try remote-debugging to see where it's going wrong, but I'm running out of time on this, so I'm hoping for a troubleshooting tip or two if I can get any.
Thanks!
Alright, figured it out. We're running Casbah/Salat on the same app, for now. There's a mongodb.uri in the config file that gets read in by both. However, ReactiveMongo seems to only work if the database name is included, which according to the mongodb "connection string uri" spec:
http://docs.mongodb.org/manual/reference/connection-string/
... you only need to include the database if you have credentials you need to authenticate with. In our case, we don't have credentials, so Casbah wasn't including the database. I added it in anyway... casbah ignored it safely, and reactivemongo worked. I neglected to do the same in the test config file, so even though it was showing the correct host, it wasn't about to work correctly.
I see how the host url + db name in one string replaces the two fields "mongodb.servers" and "mongodb.db", but it can be confusing if not conforming to mongo's similar spec.
After upgrade our IBM System i (aka i5/OS or AS/400) from V5R4 to V7R1, one of our applications that connect to DB2 using ODBC fails with the following error:
Error Code: 69899
SQLSTATE: S1000
[IBM] [System i Access ODBC Driver] [DB2 for i5/OS] PWS0005
Error occurred in the database host server code.
The symptoms are:
In a While / Wend loop a CURSOR is declared, then opens, do fetch(s) and close.
If at any iteration the cursor does not retrieve any rows, in the following iteration the error occurs after declaring the cursor (with a different SQL query) when you try to open it.
First we updated the ODBC driver to the latest version available, but the problem persists.
Because we needed an urgent solution, I solved the problem by making a pre-select to determine if the cursor will return rows, otherwise skip that iteration, this solves the problem for now but does not seem a very elegant solution.
Any idea how to get more information about the error that occurs on the host?
Thank you very much in advance.
Generally speaking, if an error occurs in the server side code, you should call IBM support and report it. They'll ask if you're on the latest cume and probably the latest database group PTFs.
The server runs the ODBC connexion in a job called QZDASOINIT. Since there are probably many connexions to the system, there are probably many QZDASOINIT jobs. To find yours, go to a terminal session and WRKOBJLCK MYPROFILE *USRPRF. You'll be presented with a list of jobs running with your user profile. At least one of them will be the QZDASOINIT job you're looking for. Use option 5 to look at the job, then option 10 to see the job log. Press F10 to see the detailed messages and F18 to go to the bottom (most recent) entries.
If the error was so severe that the server job terminated abnormally, there won't be a lock on your user profile. Instead, go to the spooled job log by using WRKSPLF.
IBM have been logging some SQL internal errors since V5R4. select * from qrecovery.qsq901s; to see any SQLCODE -901 errors.
Make sure that you have installed the latest fix pack for the latest version of System I Access
I've had this error before and it was caused by a syntax error in the connection string. It was a setting that was insignificant in older versions of the OS and more significant in newer versions, but did not cause the connection itself to fail so it was hard to track down.
For example: Port Number:8471 had a spelling mistake and was Porte Number:8471 hard to spot but once found, it fixed the problem for me. Basically everything past this part of the connection got ignored.
Wanted to add another solution to this problem. The SQL Packages that exist on your system get corrupted after/and or during upgrades. You MUST delete these packages after an upgrade. This will get rid of the old packages and will allow the system to recreate the packages at the new OS version level. When deleting SQL packages some connections/jobs may have locks on those packages so you might have to shut host services down. Use the DLTSQLPKG command to do the delete. In v7r2 and higher there are some additional steps to do as IBM changed somethings when it comes to packages you can find the info here http://www-01.ibm.com/support/docview.wss?uid=nas8N1015556
Or tell your ODBC/JDBC/.Net Data adapter/provider to not use packages. This is probably less desirable as there are performance benefits to packages.
