Method Detail

setShouldUseLocatorForLOBWrite

public void setShouldUseLocatorForLOBWrite(boolean usesLocatorForLOBWrite)

Set if the locator is required for the LOB write. The default is true. For Oracle thin driver, the locator is recommended for large size ( >4k for Oracle8, >5.9K for Oracle9) BLOB/CLOB value write.

shouldUseLocatorForLOBWrite

public boolean shouldUseLocatorForLOBWrite()

Return if the locator is required for the LOB write. The default is true. For Oracle thin driver, the locator is recommended for large size ( >4k for Oracle8, >5.9K for Oracle9) BLOB/CLOB value write.

getLobValueLimits

public int getLobValueLimits()

Return the BLOB/CLOB value limits on thin driver. The default value is 0. If usesLocatorForLOBWrite is true, locator will be used in case the lob's size is larger than lobValueLimit.

setLobValueLimits

public void setLobValueLimits(int lobValueLimits)

Set the BLOB/CLOB value limits on thin driver. The default value is 0. If usesLocatorForLOBWrite is true, locator will be used in case the lob's size is larger than lobValueLimit.
