Cesar Acuna commented on SEQUOIA-975: ------------------------------------- Hi everybody, Right now I am facing the same problem. There is a solution for this already? Sequences are correctly incremented in all DB servers but the transaction is aborted because of the problem described above. Thanks a lot Cesar > Insert statements fail after 'call Nextval' in PostgreSQL cluster > ----------------------------------------------------------------- > > Key: SEQUOIA-975 > URL: https://forge.continuent.org/jira/browse/SEQUOIA-975 > Project: Sequoia > Type: Bug > Components: Core > Versions: Sequoia 2.10.9 > Environment: Windows, Hibernate, PostgreSQL and Spring > Reporter: Love Singhal > > > I am currently facing this issue and is a blocker for me. > I have a Spring and Hibernate based Java server which is connected to > PostgreSQL database. I want to add database clustering to it using sequoia. > The server uses sequences to generate various Ids. One sequence > 'hibernate_sequence' is automatically used by the Hibernate framework. > I installed a sequoia cluster of two databases with two controllers. To > enable synchronization of sequences, I changed the sql query 'select nextval' > to '{call nextval.. }' as mentioned in the documents. For hibernate, I > defined the new SQL dialect which changes the nextVal query string. > However, I am finding that the database statements that do an insert > statement along with the 'call nextval' statement in the same transaction > fail consistently. The error returned in the logs and to the server is: > > uncategorized SQLException for SQL [insert into category (name, > > description, prefix, server_path, category_id) values (?, ?, ?, ?, ?)]; SQL > > state [null]; error code [0]; Batch failed for request 0: insert into > > category (name, description, prefix, server_path, category_id) values (?, > > ?, ?, ?, ?) > > (org.continuent.sequoia.common.exceptions.driver.DriverSQLException: > > Message of cause: write request 562949953421404 failed: > Backend ras - BackendWorkerThread for backend 'localhost2' with RAIDb level:1 > failed (ERROR: current transaction is aborted, commands ignored until end of > transaction block) > The ras is the name of the virtual database. > All kinds of insert requests (not necessarily, in the category table) are > failing when they are called along with the call nextval statement.

I tried to locate > the cause of the problem in the logs but could not find anything that > specifies the cause (even after setting up everything to DEBUG log level). I > cant do a '{call nextval}' in a separate transaction as these calls are > automatically made by hibernate. > When I revert back the '{call nextval' statement to 'select nextval', things > work fine until some primary key gets duplicated (sequences in the two > databases become unequal). Also, the update calls along with '{call nextval' > seem to succeed. > I am now stuck with this issue and could not proceed any further with > clustering.
