Suddenly my Windows XP failed to boot with this error message on a blank screen:
missing or corrupt <windows root>\system32\hal.dllI took out the hard drive, put it in a USB enclosure and attached it to another PC. Then I ran CHKDSK and it fixed some file system errors. But I did find that hal.dll was intact, so hal.dll was not missing or corrupt . It turned out that the file that was really missing was C:\boot.ini . It is a hidden file, so you have to use attrib boot.ini to see it. The file is missing if attrib boot.ini returns nothing (run in the root folder C:\). In my case I reconstructed the boot.ini file:

If you are using PL/SQL Developer, you can check this by right clicking on the queue name and make sure that "Enqueue Enabled" and "Dequeue Enabled" are checked. Deployment descriptors are correctly set up. The database user used for the JDBC connection pool has the proper privileges to enqueue and dequeue. Usually this means that the database user is assigned the AQ_USER_ROLE . The ultimate test is to run some PL/SQL code in the oc4j...
