Capture is unable to read from the online redo logs. Once the the redo log is archived onto disk, then capture is able to read the messages.
Show capture detail shows capture in "waiting" state.
Event_log shows the following:
Notice Capture: Good record was read from <system specific information> [module oct]
Notice Capture: End record skip at seqno <system specific information> [module oct]
If Oracle's setting of filesystemio_options is set to SETALL or directio, instead of ASYNCH, then Shareplex will experience this issue.
To bypass this issue, you can set the capture parameter of SP_OCT_OLOG_DIRECT. By default, this parameter is set to 0, change it to 1 then restart the capture process:
sp_ctrl>stop capture
sp_ctrl>set param SP_OCT_OLOG_DIRECT 1
sp_ctrl>start capture
