Field Detail

numPreload

public static Long numPreload

(int) The number of values to preload in this slave

numBytes

public static Long numBytes

(int) The number of bytes per blob value. NOTE: With the current driver-independent implmentation, values > 4000 are not handled correctly by Oracle's thin driver. Specifically, Oracle loses the Blob value, and a resulting getBlob yields a Blob of length 0. This is a known Oracle bug, and the only way around it is to use Oracle-specific classes (e.g. see Util.generateAndInsertBlob()).

jdbcDriver

public static Long jdbcDriver

(String) The JDBC driver class name.

jdbcUrl

public static Long jdbcUrl

(String) The JDBC URL.

rdbUser

public static Long rdbUser

(String) The RDB user.

rdbPassword

public static Long rdbPassword

(String) The RDB password.

poolMinLimit

public static Long poolMinLimit

(int) The pool minimum limit.

driverLogging

public static Long driverLogging

(boolean) Optional detailed JDBC Driver logging.

tableName

public static Long tableName

(String) The name of the RDB table that holds the data.

keyColumnType

public static Long keyColumnType

(String) The type of the key column in tableName.

valueColumnType

public static Long valueColumnType

(String) The type of the value column in tableName.

sleepMs

public static Long sleepMs

(int) The sleep time, in milliseconds: if 0, DBCacheLoader.load calls Util.getBlob to get data; if not 0, DBCacheLoader.load sleeps instead.
