I tried to test the connection on h2 console and got this error:-
The error with code 50000 is thrown when something unexpected occurs, for example an internal stack overflow. For details about the problem, see the cause of the exception in the stack trace.[General error: "java.lang.IllegalStateException: Unable to read the page at position 6322192528771 [1.4.200/6]" [50000-200] HY000/50000 (Help)][1]
Your database file is corrupted. If you need data from it, you can try to use the recovery tool. If you don't need it, you can simply delete test1.mv.db in the home directory of your user account.
When you use persistent embedded databases in H2 you should be careful with them, Thread.interrupt() may corrupt the database file, for example, unless you're using the async: filesystem. Corruption is also possible when you open the database file from a recent version of H2 with older one. The default MVStore engine also has some own problems.

I am not able to run any query to change to CDB or PDB in SQL plus it shows the above error.
For instance I tried running the query
Alter pluggable database open
and got this error.
ERROR at line 1:
ORA-65090: operation only allowed in a container database
The correct command to change Container is
ALTER SESSION SET CONTAINER = containername;
If you are getting error then you must not be a privileged user

I solved it. Though the solution is not a preferable one but it worked for me as of now. I used Database configuration assistant and deleted the pdb in which I getting connected to when logging using sqlplus. I would appreciate some proper solution to this.
Years ago I wrote an app to capture data into H2 datafiles for easy transport and archival purposes. The application was written with H2 1.4.192.
Recently, I have been revisiting some load code relative to that application and I have found that there are some substantial gains to be had in some things I am doing in H2 1.4.200.
I would like to be able to load the data that I had previously saved to the other databases. But I had some tables that used a now invalid precision scale specification. Here is an example:
CREATE CACHED TABLE PUBLIC.MY_TABLE(MY_COLUMN DATETIME(23,3) SELECTIVITY 5)
H2 databases created with 1.4.192 that contain tables like this will not load on 1.4.200,
they will get the following error:
Scale($"23") must not be bigger than precision({1}); SQL statement:
CREATE CACHED TABLE PUBLIC.MY_TABLE(MY_COLUMN DATETIME(23,3) SELECTIVITY 5) [90051-200] 90051/90051 (Help)
My question is how can I go about correcting the invalid table schema? My application utilizes a connection to an H2 database and then loads the data it contains into another database. Ideally I'd like to have my application be able to detect this situation and repair it automatically so the app can simply utilize the older data files. But in H2 1.4.200 I get the error right up front upon connection.
Is there a secret/special mode that will allow me to connect 1.4.200 to the database to repair its schema? I hope???
Outside of that it seems like my only option is have a separate classloader for different versions of H2 and have remedial operations happen in a classloader and the load operations happen in another classloader. Either that or start another instance of the JVM to do remedial operations.
I wanted to check for options before I did a bunch of work.
This problem is similar to this reported issue, but there was no specifics in how he performed his resolution.
This data type is not valid and was never supported by H2, but old H2, due to bug, somehow accepted it.
You need to export your database to a script with 1.4.192 Beta using
SCRIPT TO 'source.sql'
You need to use the original database file, because if you opened file from 1.4.192 Beta with 1.4.200, it may be corrupted by it, such automatic upgrade is not supported.
You need to replace DATETIME(23,3) with TIMESTAMP(3) or whatever you need using a some text editor. If exported SQL is too large for regular text editors, you can use a stream editor, such as sed:
sed 's/DATETIME(23,3)/TIMESTAMP(3)/g' source.sql > fixed.sql
Now you can create a new database with 1.4.200 and import the edited script into it:
RUNSCRIPT FROM 'fixed.sql'
I am trying to create a DB Link between 2 Autonomous databases (Serverless) in OCI
List of steps i followed
I created the necessary credentials for the user using dbms_cloud.create_credential
Now, i try to upload the Wallet file (which i have stored in Object storage) using "dbms_cloud.get_object". It produces the following error
ORA-20000: ORA-29283: invalid file operation: nonexistent file or path [29434]
ORA-06512: at "C##CLOUD$SERVICE.DBMS_CLOUD", line 983
ORA-06512: at "C##CLOUD$SERVICE.DBMS_CLOUD", line 2622
ORA-06512: at line 2
If i use the wrong credential or if i change the uri, the error that the system produces are different. I believe oracle is able to get to the object, yet it produces this error.
Any ideas?
DBMS_CLOUD.GET_OBJECT supports ability to read data from an object store file and return the contents as a BLOB, or save the contents to a file in the given directory object in your Autonomous Database.
https://docs.oracle.com/en/cloud/paas/autonomous-database/adbsa/dbms-cloud-subprograms.html#GUID-3DB888C9-18C7-4A26-8DA8-EDFB260E2B14
It seems that you are trying to download a Wallet file to directory object for creating a database link. Autonomous Database automatically provisions a database file system to store files. Although the exact SQL syntax is not posted, but the error indicates that the syntax is correct. The error appears like the database file system is not accessible, and it is an internal error for the service.
You could workaround the issue by restarting the Autonomous Database. As this is an old question, the issue could be automatically addressed by now with automatic maintenance of Autonomous Database.
Out of curiosity, what region are you experiencing this in? Free tier or paid?
Ultimately, there is nothing wrong with your syntax used or a wrong usage. Unfortunately the issue you're experiencing is likely an internal error/bug, and can be fixed by OCI ops. I highly recommend submitting a service request.
If you have not submitted one in the past, you can read up on how to here - https://docs.cloud.oracle.com/en-us/iaas/Content/GSG/Tasks/contactingsupport.htm#3Openasupportservicerequest
Few days ago while i tried perform database copy from remote server to local server i got some warnings and one of them was like this
"Error occured executing DDL for TABLE:MASTER_DATA".
And then i clicked yes, but the result of database copy was unexpected, there were only few tables has been copied.
When i tried to see DDL from SQL section/tab on one of table, i got this kind of information
-- Unable to render TABLE DDL for object COMPANY_DB_PROD.MASTER_DATA with DBMS_METADATA attempting internal generator.
I also got this message and i believe this message showed up because there's something wrong with DDL on my database so tables won't be created.
ORA-00942: table or view does not exist
I've never encountered this problem before and i always perform database copy every day since two years ago.
For the record before this problem occurred, i have removed old .arch files manually not by RMAN and i never using any RMAN commands. I also have removed old .xml log files, because these two type of files have made my remote server storage full.
How to trace and fix this kind of problem? Is there any corruption on my Oracle?
Thanks in advance.
The problem was caused by datafile has reached its max size though. I have resolved the problem by following the answer of this discussion ORA-01652: unable to extend temp segment by 128 in tablespace SYSTEM: How to extend?
Anyway, thank you everyone for the help.
Context
I have been debugging an Oracle Weblogic Server 10.3.0.0 JDBC Connection which is logging the error code:
BEA-001112
After some searching around I found a bit of an explanation here:
http://docs.oracle.com/cd/E21764_01/core.1111/e10106/dbac.htm#BHCFFAJF
Although it does depend on the actual exception being thrown, I believe this means:
there was an error when testing a new connection in the JDBC Connection Pool before handing it off to be used by the application.
Question
Does anyone know of a list of Weblogic Error Codes that has a general description for the specific Error Code?
In Oracle portfolio WebLogic is a part of Oracle Fusion Middleware (OFMW). Thus the error code (or message) list is a part of OFMW documentation.
As the links a quite difficult to find for uninitiated here's direct links to a few different releases.
WebLogic 10.3.3
WebLogic 10.3.6
WebLogic 12.1.3
They are not much descriptive, but hopefully can give you at least an introduction. You can also index them by subsystem. Clicking on a message (or message range) will bring up the details.
Cause: The specified data source connection pool has been configured with one or
more attributes to test the pool connections. One of those test attempts failed. The
associated error is printed.
Action: Check the associated error to see what the problem is and correct it.
Normally, this indicates that a connection was lost to the database (the database is
down). This needs to be corrected by the database administrator.
