• --classpath
  • H2® ships from a single Java binary file, for example h2-2.3.232.jar.
  • The option specifies the path to the H2® Java binary file, by default the current directory is used: ./h2-2.3.232.jar.
• --url
  • Specifies the location of the H2® database. The JS7 - Database using H2® is located with JOC Cockpit from the <jetty-base>/resources/joc/h2 directory. The name of the database is joc.
  • The URL is prefixed with jdbc:h2: followed by the relative or absolute path to the database. If the prefix is omitted, it will be added by the script.
  • Examples:
    • jdbc:h2:/var/sos-berlin.com/js7/joc/resources/joc/h2/joc
    • /var/sos-berlin.com/js7/joc/resources/joc/h2/joc
• --driver
  • Specifies the class name of the H2® JDBC Driver, default: org.h2.Driver.
• --user
  • Specifies the account for the H2® database, default: joc.
• --password
  • Specifies the password used for the account specified with the --user option for the H2® database, default: no password.
  • Password input from the command line is considered insecure. Consider use of the -p switch offering a secure option for interactive keyboard input.
• --file
  • When used with the export command, specifies the path to the .zip archive file that holds the full database backupexport.
  • When used with the import command, specifies the path to the .sql script file used for import. This offers to restore the database from a previous full export.
  • When used with the shell command, specifies the path to the .sql script file that holds SQL statements that should be executed.
• --file-versions
  • When used with the export command, specifies the number of versions for which backup files will be stored
• --sql
  • When used with the shell command specifies the SQL statement that should be executed.
  • Consider to apply quotes as with --sql="SELECT COUNT(*) FROMM JOC_VARIABLES;". SQL statements should be terminated by semicolon.
• --web-port
  • When used with the console command specifies the port used by the H2® Console, default: 8082.

The following examples illustrate typical use cases.

Invoking

...

H2 Console

# invoking the H2 Console for default port 8082
./operate-h2.sh console

# invoking the H2 Console for the port specified using the Java binary from the current directory
./operate-h2.sh console --web-port=8081 --classpath=./h2-2.3.232.jar

Invoking

...

H2 Shell

# invoking the H2 Shell using the Java binary from the current directory
./operate-h2.sh shell --url="/var/sos-berlin.com/js7/joc/resources/joc/h2/joc" --classpath=./h2-2.3.232.jar

...

# export database to .zip archive file that holds the script.sql file
./operate-h2.sh export --url="/var/sos-berlin.com/js7/joc/resources/joc/h2/joc" --user=joc --file=/tmp/database-export.zip

# export database to .zip archive file with up to 3 versions
./operate-h2.sh export --url="/var/sos-berlin.com/js7/joc/resources/joc/h2/joc" --user=joc --file=/tmp/database-export.zip --file-versions=3

# export database from a docker container to a volume
docker exec -ti js7-saas-2-7-2 /bin/bash \
    /opt/sos-berlin.com/js7/script/operate-h2.sh export \
    --classpath=/var/sos-berlin.com/js7/joc/lib/ext/joc/h2-2.3.232.jar \
    --url="/var/sos-berlin.com/js7/joc/resources/joc/h2/joc;AUTO_SERVER=TRUE" \
    --user=joc  \
    --file=/var/sos-berlin.com/js7/joc/resources/joc/database-export.zip \
    --file-versions=3
