OGG-01031 Pump Abending

A fairly common occurance in the Golden Gate world. The pump abends as the target destination becomes full.
In this scenario, simply clearing space on the drive will not restart the pump.
The pump complains as below

2013-05-14 10:41:42 INFO OGG-00993 Oracle GoldenGate Capture for Oracle, p1ppppd1.prm: EXTRACT P1PPPPD1 started. 2013-05-14 10:41:47 INFO OGG-01226 Oracle GoldenGate Capture for Oracle, p1ppppd1.prm: Socket buffer size set to 27985 (flush size 27985). 2013-05-14 10:41:58 ERROR OGG-01031 Oracle GoldenGate Capture for Oracle, p1ppppd1.prm: There is a problem in network communication, a remote file problem, encryption keys for target and source do not match (if using ENCRYPT) or an unknown error. (Reply received is Unable to open file "/u01/oraogg/dirdat/rp/rp000014" (error 13, Permission denied)). 2013-05-14 10:41:58 ERROR OGG-01668 Oracle GoldenGate Capture for Oracle, p1ppppd1.prm: PROCESS ABENDING.

We tell the pump to Rollover onto a new trace file.

alter extract P1PPPPD1 etrollover
2013-05-14 10:57:19 INFO OGG-01520 Oracle GoldenGate Command Interpreter for Oracle: Rollover performed. For each affected output trail of Version 10 or higher format, after starting the source extract, issue ALTER EXTSEQNO for that trail's reader (either pump EXTRACT or REPLICAT) to move the reader's scan to the new trail file; it will not happen automatically.

Run info pumpname to get the new trail file name.

At the target end, the replicat should have parsed all the data received until the drive became full and data stopped coming through.
To let the target know to switch to the new file, use below command.

alter replicat R1PPPPD2 ,EXTSEQNO 15 , EXTRBA 0 --- replicat was reading the seqno 14. moved to 15.
