Migrating Database

Please refer to Database Prerequisites before proceeding with the migration details.

Introduction

As HSQL is not suitable for production usage, OpsHub Integration Manager needs to be migrated to one of three databases supported by OpsHub Integration Manager. There is a utility provided with OpsHub Integration Manager installation and packaged in OpsHub Integration Manager's <Installation Directory>\OpsHub_Resources\DatabaseMigrator directory [Migrator directory].

Steps to migrate from HSQL to other supported databases

• Keep driver for database for which migration needs to be done in: OpsHub Integration Manager's <Installation Directory>\OpsHubServer\lib directory.

  • For MySQL connector driver jar 5.1.8 is not supported, hence the latest connector driver jar should be used from http://dev.mysql.com/downloads/connector/j/5.1.html

• Change destinationconnection.properties and sourceconnection.properties in Migrator directory:

  • sourceconnection.properties: Change CONNECTION_HSQL_FILE_PATH property and replace <installation path> with installation path

  • destinationconnection.properties: Provide all properties value as guided in file.

    * Take back up of database

Refer to Database Backup section on Taking Application Backup page for details.

Migrating on Windows

Run migrator.bat in Migrator directory

Migrating on Linux

Run migrator.sh in Migrator directory If file execution fails with ^M bad interpreter error, use following steps:

• Execute command in terminal dos2unix migrator.sh

• Now execute the sh file in terminal migrator

Steps to perform after successful migration

Following are the steps to be performed after successful database migration:

• Go to OpsHub Integration Manager's <Installation Directory>\OpsHubServer\webapps\OpsHubWS\META-INF directory

• Delete war-tracker file

• Go to OpsHub Integration Manager's <Installation Directory>\OpsHubServer\webapps\OpsHubWS directory

• Select all the files and add to archive with name OpsHubWS.zip

• Rename OpsHubWS.zip to OpsHubWS.war

• Go to OpsHub Integration Manager's <Installation Directory>\OpsHubServer\webapps and replace newly created OpsHubWS.war with the existing one

• Delete OpsHub Integration Manager's <Installation Directory>\OpsHubServer\webapps\OpsHubWS directory and start the service.
