    Table 'XXXXX' already exists

    Marek Neumann Novice

      Hi all,

      I encoutered a CMP problem when I wanted to let JBoss (3.2.0RC1) to create my table in oracle. With one table, JBoss always states that it "already exists". However, the table is 100% not in the database. What is strange here, if I rename the <table-name> in jbosscmp-jdbc.xml the table is created then. All other tables are created correctly. What is wrong here? Anything with the cache or a bug?

          JBoss fires select count(*) from to see if the table exists or not. Double check by logging in using the user id and password that jboss uses.

            JBoss actually uses DatabaseMetaData.getTables() to determine is the table exists. With Oracle this can return misleading information if the user can access a table with the same name in another schema.

            You can verify this by logging in as your user and do
            select table_name from all_tables.

            If you intend to use that table you can fully qualify the name; if you don't, you might want to lock down the database a bit.

              You actaully replied to another email of mine, where tables of the same name exists in 2 different schemas, and jboss won't create/deploy into the other schema because it is seen in the MetaData.

              I applolgise, my Oracle dba skills are not well developed. I understand what is happeneing, I just don't know how to fix it.

              What can I do in Oracle to prevent this from happening? Meaning, if a fix is to change the grants, what would I change and how? I have no problem dropping the user and re-creating him.

                My problem turned out to be in the User creation script. The grants were the issue. Before I was granting all priviledges to the users. I'm an ignorant Oracle dba. Much thanks to jboynes insight. Here is my script I finally used to create the user(s) with:

                set echo on;
                drop tablespace devl including contents;
                create tablespace devl datafile 'devl.dbf' size 100M reuse;
                DROP USER devl CASCADE;
                create user devl identified by devl default tablespace devl;
                GRANT RESOURCE TO Devl;
                grant CREATE SESSION to Devl;
