topics: LOB Column States Locking a Row Containing a LOB Opening and Closing LOBs LOB Locator and LOB Value LOB Locators and BFILE Locators Accessing LOBs LOB Rules and Restrictions LOB Column States loadjava command not found The techniques you use when accessing a cell in a LOB column differ depending on the state of the given cell. A cell in a LOB Column can be in one of the following states: NULL The table cell is created, but the cell holds no locator or value. Empty A LOB instance with a locator exists in the cell, but it has no value. The length loadjava utility of the LOB is zero. Populated A LOB instance with a locator and a value exists in the cell. Locking a Row Containing a LOB You can lock a row containing a LOB to prevent other database users from writing to the LOB during a transaction. To lock a row containing a LOB, specify the FOR UPDATE clause when you select the row. While the row is locked, other users cannot lock or update the LOB, until you end your transaction. Opening and Closing LOBs The LOB APIs include operations that enable you to explicitly open and close a LOB instance. You can open and close a persistent LOB instance of any type: BLOB, CLOB, NCLOB, or BFILE. You open a LOB to achieve one or both of the following results: Open the LOB in read-only mode. This ensures that the LOB (both the LOB locator and LOB value) cannot be changed in your session until you explicitly close the LOB. For example, you can open the LOB to ensure that the LOB is not changed by some other part of your program while you are using the LOB in a critical operation. After you perform the operation, y

I have not experienced this problem before and do not see any similar postings. There appears to be an internal error, but I'm hoping it's my mistake.

External Procedures Index Colophon Using loadjavaThe loadjava utility is an operating system command-line utility that uploads Java files into the database. The first time you run loadjava in a schema, it creates a number of elements for its own use: CREATE$JAVA$LOB$TABLEA table created in each schema, containing Java code elements. Each new class you load using loadjava will generate one row in this table. JAVA$CLASS$MD5$TABLEA hash table , also referred to as the digest table, used to track the loading of Java elements into a given schema. LOADLOBSA package that is installed in each schema, used to load Java code elements as large objects (LOBs) into the database. Using LOADLOBS, loadjava moves Java files into a BLOB column in the database table CREATE$JAVA$LOB$TABLE. It also checks the JAVA$CLASS$MD5$TABLE.MD5 hash value to see if the loaded classes have been loaded previously and whether they have been changed (thereby minimizing the need to
