ERROR OGG-00446 Oracle GoldenGate Capture for Oracle, XXXX.prm: No valid log files for current redo sequence X, thread X, error retrieving redo file name for sequence X, archived = 0, use_alternate = 0Not able to establish initial position for begin time

While starting goldengate extract process, extract PROCESS ABENDING with below error message. It was due to filesytem mismatch, goldengate extract process was unable to extract data from file. I have created archive log destination in ASM storage. To overcome below error message we need to use TRANLOGOPTIONS and DBLOGREADER in extract parameter file.

ERROR   OGG-00446  Oracle GoldenGate Capture for Oracle, ex1.prm:  No valid log files for current redo sequence 8, thread 1, error retrieving redo file name for sequence 8, archived = 0, use_alternate = 0Not able to establish initial position for begin time 2018-12-18 00:44:48.000000.

sample extract parameter file after modification:-
EXTRACT ex1
USERID gguser PASSWORD gguser

DISCARDFILE /home/oracle/gghome/dirrpt/ex1.dsc, APPEND, MEGABYTES 50
EXTTRAIL /home/oracle/gghome/dirdat/ex

TRANLOGOPTIONS DBLOGREADER, DBLOGREADERBUFSIZE 4194304

TRANLOGOPTIONS BUFSIZE 10000000

TABLE us01.*;

PARAMETER	DESCRIPTION
TRANLOGOPTIONS	Specific directives while mining transactions
DBLOGREADER	New ASM API to extract data
BUFSIZE	Max bytes of memory allocated to read redo data – Increases Capture Speed
DBLOGREADERBUFSIZE	Increases Maximum read size for ASM

 after added parameters TRANLOGOPTIONS and DBLOGREADER in extract parameter file, the issue resolved.
