Migration Commands

Command Syntax

This syntax developed by considering four types of profiles. Please find the details in Profiles. Where default profiles are blank. Need not to mention in Maven build.

# mvn clean install -P[[[diff]database,]context,]command
# mvn clean install -P[[[dat,]mys,]dev,]log

mvn clean install -Pmys,dev,log      # mysql , development
mvn clean install -Pora,pro,log      # oracle, production
mvn clean install -Pdev,log          # h2    , development
mvn clean install -Plog              # h2    , development

Generate Change Log

# exclude data mvn clean install -Pmys,dev,log # mysql , development mvn clean install -Pora,pro,log # oracle, production mvn clean install -Pdev,log # h2 , development mvn clean install -Plog # h2 , development

Synchronize Change Log

mvn clean install -Pmys,dev,syn                        # mysql , development
mvn clean install -Pora,pro,syn                        # oracle, production

mvn clean install -Psyn                                # h2    , development

Migrate/Update Database

mvn clean install -Pmys,dev,upd                        # mysql , development
mvn clean install -Pora,pro,upd                        # oracle, production

Profiles

Four types of profiles are considerate for Maven build. Please find those profiles details are as respectively as below:

1. Diff (dat, default)
2. Database (der, h2d, hsq, mys, ora, pos, default)
3. Context (dev, qac, uat, pro, default)
4. Command (log, dif, syn, upd, cle, rol, del)

Where default profiles are blank. Need not to mention in Maven build.
