Blocked:DDR
Posted in 2000
Was wondering if anyone could help me with this problem.
We are running IDS 7.31.UC4 on HP-UX 11.0.
ER is defined to replicate between 4 servers, 1 server is a Primary and the other 3 are Targets (Read only).
One of our target servers has locked all user threads because it is Blocked:DDR.
No querries can be performed on this instance.
I tried bouncing the engine but when the server came back online it went back to the same state, has anyone experienced this before?
Thanks,
Andrew Ford
