  • Field Details

    • SCHEMA_NAME

      static final String SCHEMA_NAME
      The name of the DB schema to use for the repository. If omitted the default schema name of the repository's DB adapter is used as the schema name.

      4.13

    • PREPEND_SCHEMA_NAME

      static final String PREPEND_SCHEMA_NAME
      Whether to qualify table names with the schema name.

    • CREATE_SCHEMA_IF_NEEDED

      static final String CREATE_SCHEMA_IF_NEEDED
      Whether to create the schema with the specified name at startup time, if it does not exist.
      Since:
      4.13
      See Also:

    • CONNECTION_KEEPALIVE_PERIOD

      static final String CONNECTION_KEEPALIVE_PERIOD
      Period at which to execute an SQL statement to keep DB connection alive, in minutes.
      See Also:

    • BATCH_STATEMENT_SIZE

      static final String BATCH_STATEMENT_SIZE
      Maximum number of pending parameter sets per JDBC batch statement. If absent, the legacy org.eclipse.emf.cdo.server.db.LIST_BATCH_SIZE property is used as the default.
      Since:
      4.15
      See Also:

    • OBJECT_TYPE_BATCH_SIZE

      static final String OBJECT_TYPE_BATCH_SIZE
      Maximum number of ObjectType rows considered by one prequery and ObjectType insert batch.

      If omitted, BATCH_STATEMENT_SIZE and its legacy fallback behavior determine the size.

      Since:
      4.15
      See Also:

    • OBJECT_TYPE_DUPLICATE_POLICY

      static final String OBJECT_TYPE_DUPLICATE_POLICY
      ObjectType duplicate handling mode: SAFE or FAIL. SAFE is the default and preserves duplicate detection and replay. FAIL skips those safeguards and requires all committed IDs to be fresh. FAIL is suitable only when the operator guarantees that commits cannot introduce already-persistent IDs; use SAFE for merge, import, backup, clone, and other external-permanent-ID scenarios.
      Since:
      4.15
      See Also:

    • BATCH_COMMIT_SIZE

      static final String BATCH_COMMIT_SIZE

    • CONNECTION_RETRY_SECONDS

      static final String CONNECTION_RETRY_SECONDS
      Number of seconds to wait before additional attempts to connect to the DB after initial connection failure.

    • ZIP_PACKAGE_BYTES

      static final String ZIP_PACKAGE_BYTES
      Whether to store packages as zipped byte arrays in the database.

      When set to true, packages are stored as zipped byte arrays. This saves database space, but makes it harder to inspect the stored packages outside of CDO.

      When set to false (the default), packages are stored as plain XML/XMI.

      The default value is determined by the "org.eclipse.emf.cdo.server.internal.db.MetaDataManager.ZIP_PACKAGE_BYTES" system property, which defaults to true.

      Note: This property only affects newly stored packages. Existing packages are not converted.

      4.14
      See Also:

    • DISABLE_SQL_QUERY_HANDLER

      static final String DISABLE_SQL_QUERY_HANDLER
      Whether to disable the SQL query handler.

      When set to true, the SQL query handler is disabled. This means that clients cannot execute arbitrary SQL queries against the database.

      When set to false (the default), the SQL query handler is enabled.

      The default value is determined by the "org.eclipse.emf.cdo.server.db.DEFAULT_DISABLE_SQL_QUERY_HANDLER" system property, which defaults to false.
