ERROR OGG-00868 Error code 1291, error message: ORA-01291: missing logfile

Question

OGG Version 12.1.2.1.0 OGGCORE_12.1.2.1.
DB : 11.2.0.4.3
I am getting below error.
2014-12-31 09:53:09  ERROR   OGG-00868  Error code 1291, error message: ORA-01291: missing logfile
  (Missing Log File <unknown>. Read Position SCN: 2585.802983323 (11103293443483)).
Our solution uses ADG and OGG
We have source and target where ADG was setup . We later broke ADG setup and made Oracle DB's in source and target into standalone.
As part of our solution during our deployment window ,we would break ADG i.e we would make both the source and target as independent DB’s with PRIMARY Read /Write mode.
-Take Guaranteed restore point on Source DB so that we can flash back at later stage(so of now we have not executed flash back command)
-Once ADG config is disabled we will start the OGG extract which is already configured before =We are at this stage where we are hit with errors and extract is not starting .

Answer 1

Hi ,
The error shows it is waiting for the Logfile. The Integrated extract mainly needs of the availability of two things.
1. Archivelogs.
2. Trail Files.
Both should be retained to the needed / required level.
Please execute the below query and check the status of the Extract / Capture process.
The below query displays the information of each capture process in a database.,
COLUMN CAPTURE_NAME HEADING 'Capture|Name' FORMAT A7
COLUMN PROCESS_NAME HEADING 'Capture|Process|Number' FORMAT A7
COLUMN SID HEADING 'Session|ID' FORMAT 9999
COLUMN SERIAL# HEADING 'Session|Serial|Number' FORMAT 9999
COLUMN STATE HEADING 'State' FORMAT A20
COLUMN TOTAL_MESSAGES_CAPTURED HEADING 'Redo|Entries|Evaluated|In Detail' FORMAT 9999999
COLUMN TOTAL_MESSAGES_ENQUEUED HEADING 'Total|LCRs|Enqueued' FORMAT 9999999999
SELECT c.CAPTURE_NAME,
       SUBSTR(s.PROGRAM,INSTR(s.PROGRAM,'(')+1,4) PROCESS_NAME,
       c.SID,
       c.SERIAL#,
       c.STATE,
       c.TOTAL_MESSAGES_CAPTURED,
       c.TOTAL_MESSAGES_ENQUEUED
  FROM V$STREAMS_CAPTURE c, V$SESSION s
  WHERE c.SID = s.SID AND
        c.SERIAL# = s.SERIAL#;
Also run this query to check, if the capture is waiting for which logfile.,
COLUMN CONSUMER_NAME HEADING 'Capture|Process|Name' FORMAT A15
COLUMN SOURCE_DATABASE HEADING 'Source|Database' FORMAT A10
COLUMN SEQUENCE# HEADING 'Sequence|Number' FORMAT 99999
COLUMN NAME HEADING 'Required|Archived Redo Log|File Name' FORMAT A40
SELECT r.CONSUMER_NAME,
       r.SOURCE_DATABASE,
       r.SEQUENCE#,
       r.NAME
  FROM DBA_REGISTERED_ARCHIVED_LOG r, DBA_CAPTURE c
  WHERE r.CONSUMER_NAME =  c.CAPTURE_NAME AND
        r.NEXT_SCN      >= c.REQUIRED_CHECKPOINT_SCN;
The above query clearly shows for which logfile the Extract / Capture process is waiting. Check if that logfile is available in your system.
