I have moved 5G permspace under user A for his stored procedures. After he finished the task, he dropped his procedures and I tried to move out this 5G permspace back to other database. Move space succeeded, but I noticed that Teradata administrator still shows that there is about 40 bytes maxperm under this user. has any body encounered that before? Besides, we are using V2R5. At the time this user was running his procedures, one node of our teradata database down and then the whole system down. Our maitenance guys said 'There was a problem with node 1-5 accessing VPROCS due to a DR in the PDE portion of the database. The DR is fixed in the latest patches for 5.1.2.' Could anybody explain that too..
