Hi All,

I tried to run a delete query in SPUFI.

Code:
DELETE                               
FROM     HIST_QUANTITY         
WHERE    TERMINAL_ID = 'SPRLOD' 


the above query was suppose to delete 1574180 rows from the table.

but I am getting a -904 error with the following reason.
Code:
SQLCODE = -904, ERROR:  UNSUCCESSFUL EXECUTION CAUSED BY AN         
UNAVAILABLE RESOURCE. REASON 00C90096, TYPE OF RESOURCE 00000302, AND
RESOURCE NAME TCPUD1PK.PK000070.X'00004E8A'


need help on how to increase the page locks. or is there any optimization needed for the query to be executed so, that the table doesn't throw -904.

Thanks in Advance

The table did not 'throw' anything. Nothing gets thrown on the mainframe. Your query abended.

You can use the below to lock the entire table prior to the delete. You need to be sure no one else needs the table
LOCK TABLE HIST_QUANTITY IN EXCLUSIVE MODE

Such things are always discussed with DBAs.
Please do that
