Method Detail

setShouldUseLocatorForLOBWrite

public void setShouldUseLocatorForLOBWrite(boolean usesLocatorForLOBWrite)

PUBLIC: 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.

Overrides:

setShouldUseLocatorForLOBWrite in class Oracle8Platform

shouldUseLocatorForLOBWrite

public boolean shouldUseLocatorForLOBWrite()

PUBLIC: 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.

Overrides:

shouldUseLocatorForLOBWrite in class Oracle8Platform

getLobValueLimits

public int getLobValueLimits()

PUBLIC: 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.

Overrides:

getLobValueLimits in class Oracle8Platform

setLobValueLimits

public void setLobValueLimits(int lobValueLimits)

PUBLIC: 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.

Overrides:

setLobValueLimits in class Oracle8Platform
