I am using DMS to migrate date from MySQL to Redshift. I need to add new task,but it does not run because endpoint connection test fails, but I use already working endpoint. Although task with this endpoint is running without error, test is failing with this strange error
Test Endpoint failed: Application-Status: 1020912, Application-Message: Failed in prepare imp for Redshift Base general error.
Restarting DMS instance fixed the issue.

So, while validating the pipeline created in azure data factory.
I am facing this issue while running azure databricks linked service.
Error details:
Run result unavailable: job failed with error message Library installation failed for library due to user error for jar: "dbfs:/mnt/mopireport/TeamsAnalyticsCore-v9.jar" . Error messages: Library installation attempted on the driver node of cluster 0805-090147-ulpmkivi and failed. Please refer to the following error message to fix the library or contact Databricks support. Error Code: DRIVER_LIBRARY_INSTALLATION_FAILURE. Error Message: java.lang.Throwable: shaded.databricks.org.apache.hadoop.fs.azure.AzureException: com.microsoft.azure.storage.StorageException: This request is not authorized to perform this operation using this resource type.
Background:
This library is mounted to dbfs url (verified the mount is success)
Databricks is pointing to right cluster (verified)
I have permissions to edit and publish data pipeline in ADF.
Alternate tried:
I tried using adfss instead of wasbs for mounting, but wasbs is the right one. As it does and adfss gives error.
Directly goto cluster -> libraries -> install new -> select "DBFS/ADLS" as library source and type as JAR and try upload. this upload also fails with same message as above.
I am trying to connect to AWS Managed Cassandra using Perl. It's not working due to a vague error Error 0: Internal Server Error.
Using the DBD::Cassandra Library, I can connect to self hosted Cassandra clusters, but not AWS Cassandra. I think I have the AWS Root CA correct because it verifies with openssl s_client -connect cassandra.us-east-1.amazonaws.com:9142
DBI->connect("dbi:Cassandra:host=cassandra.us-east-1.amazonaws.com;port=9142;tls=1;keyspace=keyspace",
"**username**", "**password**");
The error response from the connection is
Unable to connect to any Cassandra server.
Last error: On cassandra.us-east-1.amazonaws.com:
Error 0: Internal Server Error
I can also connect using the cqlsh client and verified that the connection details are correct.
Any hints or a working example would be very helpful.
The issue appears to be setting the keyspace. Doing this either on the connection or subsequently with use keyspace results in a Error 0: Internal Server Error response from the server.
Also note that AWS Managed Cassandra only supports consistency local_quorum. The following will result in a valid connection:
DBI->connect("dbi:Cassandra:host=cassandra.us-east-1.amazonaws.com;
port=9142;tls=1;consistency=local_quorum",
"**username**", "**password**");
Since there are issues setting the keyspace, tables must be referenced using keyspace.tablename in queries.
Deleting a service key fails with internal server error.
The following command produces the error:
cf dsk -f storage storage-keys
Deleting key storage-keys for service instance storage as user...
FAILED
Server error, status code: 502, error code: 10001, message: Service broker failed to delete service binding for instance storage: Service broker error: Internal Server Error
The error seems to be specific to this service key. It is a service key of a S3 storage service. I tried for several days with always the same error result. Withing the same time span deleting othe service keys (of Maria DB services) worked as expected.
This is a Swisscom specific problem that we have experienced as well. The only way to resolve the error was to send a direct support request via this form:
https://developer.swisscom.com/support
They will then proceed to manually delete the binding and ideally fix the related server error.
This is regarding WSO2 API Manager Worker cluster configuration with external Postgres db. I have used 2 databases i.e wso2_carbon for registry and user management and the wso2_am, for storing APIs. Respective xmls have been configured. The postgres scripts have been run to create the database tables. My log console when wso2server.sh is run, shows enabled clustering and the members of the domain. However on the https://: when I try to create to create APIs, it throws and error in the design phase itself.
ERROR - add:jag org.wso2.carbon.apimgt.api.APIManagementException: Error while checking whether context exists

As per the error message, the driver class name you have given is org.postgres.Driver which is not correct. It should be org.postgresql.Driver. Double check master-datasource.xml config.
Hi I am trying to connect Oracle 10g(Source/Target) from ssis
using connection string as
Data Source=Qrgo;User ID=sy;password=sa;Provider=MSDAORA.1;
Qrgo is Servicename
getting error
Test connection failed because of an error in initializing provider. ORA-12520: TNS:listener could not find available handler for requested type of server
Please advise how to resolve this. Thanks
I have tried
1.tnsping
it is successful
2.Attempt a connection to the instance
Once you have proven that the tnsnames is talking to the listener properly, the next step is to attempt a full connection to the instance. To do this we.ll use sqlplus:
sqlplus [username]/[password]#
it is successful
but ,while trying to configure from ssis it is throughing an error
Error: ORA-12520
Text: TNS:listener could not find available handler for requested type of server
Cause: None of the known and available service handlers for requested type of server (dedicated or shared) are appropriate for the client connection.
Action: Run "lsnrctl services" to ensure that the instance(s) have
registered with the listener and that the appropriate handlers are accepting connections.
