HDR and ER Running Together

Set up is as follows: IDS 9.4 on AIX 5.3 ----------> ER over LAN -----------> IDS 10 on Solaris 2.8 | |------> IDS 11 on Solaris 2.10 V Sync HDR over WAN | V IDS 9.4 on AIX 5.3 Note ER is Primary to Secondary (one way). With this setup I am seeing lines in the error log of the HDR/ER Primary as follows: ER can not send replicated transactions due to HDR hang ER resume transmission of ER/HDR replicated transactions Also a few days ago the HDR secondary lost contact with the primary and couldn't automatically re-establish (brief network glitch). I stopped and restarted the secondary and this HDR re-established, but while HDR was not running (and until the logs had shipped and applied up to date) ER was frozen. I am trying to understand why ER keeps stopping (albeit briefly) and will not run while HDR is not connected. My suspicion is that it is related to the fact I have HDR in Synchronous mode but would like this confirmed. Also, if this is the case, is it possible to switch between Synchronous and Asynchronous modes without restarting instances ? Many Thanks in anticipation Keith

I would suspect synchronous mode is the culprit also, but no proof. You would have to bounce both HDR instances to change the mode to asynch with zero timeout.
