Non clustered confluence database is being updated by another confluence instance

[페이레터 POQ]

We've installed two confluence at one windows web server as a service, (use 8090, 8092 port)

one MSSQL DB server with two category .

Each confluence started without problem.

but sometimes one confluence occured fatal error during live service :

Non Clustered Confluence: Database is being updated by another Confluence instance. Please see http://confluence.atlassian.com/x/mwiyCg for more details.

We restart service when this error occured, but it happens again.

Hi,

The error is related to not having a data center license for your Confluence and you're trying to cluster with the two instances. 

You'll have to get a data center license to run two Confluences.

Thank you for your answer Edwin.

We bought two server license for confluence because we run wiki at private network.

two confluence works well usually, but one broke down sometimes.

Do both Confluence servers use the same DB?

[페이레터 POQ]

no, same DB server, seperated catalog (different DB)

Usually, that error can be one of the following options:

- Two instances connected to the same database schema.
- The database logs are full and are holding the connection.

I'd check the database connection in the confluence.cfg.xml just to ensure that each instance is connected to a specific schema.

same server, seperated db, but schema is same , 'dbo' . is it can occurs problem?

<property name="hibernate.connection.url">jdbc:sqlserver://10.10.10.10:7302;databaseName=CONFLUENCE_IMPAY_DB</property>

<property name="hibernate.connection.url">jdbc:sqlserver://10.10.10.10:7302;databaseName=CONFLUENCE_DB</property>

That looks fine, they should be completely separated.

You'll want to check the database logs as Guilherme mentioned.

thank you for your interest, Nic. 

how can I check database log ?

[Nic Brough -Adaptavist-]

Go to the database server and find the logs for the database system.
