clob

问题 I have a table in Oracle Database as follows, create table test_clob( id1 number, clob_col clob); If i try to insert a varchar2 variable with size more than 4000 into the CLOB column, it inserts without any problem. insert into test_clob values (1,rpad('a',32760,'a')); commit; If i try to update the CLOB column as follows, it works perfectly fine. update test_clob set clob_col = rpad('b',32760,'b') where id1 = 1; commit; However, if i try to run the update statement as follows, it is failing

问题 I recently upgraded an application to run using JAVA 7 and JBoss 7.1.1 This application was originally developed on JAVA 5 and Jboss 4.2.2. This application uses hibernate 3 for persistence.

I am using ojdbc14.jar (backend database Oracle 10.2.0.3) These are things that I have verified in jboss 7.1.1 configuration: Creation of the correct module for Oracle.

问题 I have a requirement to use the built in REPLACE function on a CLOB variable as part of a larger PL/SQL process. I'm using Oracle 11g R2 and the function works OK, in that it does the replace as required, but as the procedure runs (there are around 2.5 millions records to process), it slows down badly - as in: first 20,000 records: ~12 minutes second 20,000 records: ~24 minutes third 20,000 records: ~37 minutes fourth 20,000 records: ~52 minutes etc...
