Field Detail

numPreload

public static java.lang.Long numPreload

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

numBytes

public static java.lang.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 java.lang.Long jdbcDriver

(String) The JDBC driver class name.

jdbcUrl

public static java.lang.Long jdbcUrl

(String) The JDBC URL.

rdbUser

public static java.lang.Long rdbUser

(String) The RDB user.

rdbPassword

public static java.lang.Long rdbPassword

(String) The RDB password.

poolMinLimit

public static java.lang.Long poolMinLimit

(int) The pool minimum limit.

driverLogging

public static java.lang.Long driverLogging

(boolean) Optional detailed JDBC Driver logging.

tableName

public static java.lang.Long tableName

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

keyColumnType

public static java.lang.Long keyColumnType

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

valueColumnType

public static java.lang.Long valueColumnType

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

sleepMs

public static java.lang.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.
