OGG-01668 PROCESS ABENDING

I have checked related sequence of Archivelog, it exists in the database. If it doesn’t exist, then restore the related archivelogs from backup.

If you don’t know how to restore archivelog from Backup, then read the following article.

Restore Tablespace, Archivelog and Datafile via RMAN | Oracle RMAN ( Recovery Manager ) Restore Recover Tutorials -5

 

 

 

 

Alter Extract Process

If Related archivelog exists and Goldengate still gives same error, then reset Goldengate like following.

 

GGSCI (MehmetSalih) 15> ALTER EXTRACT EXT01, BEGIN 2019-03-19:16:54:00

Start Goldengate Process

Goldengate is reset and I have changed extract process to one minute ago from current time.

Now I have started extract process again like following.

Goldengate has been syncronized like above.

 

 

If your problem has not solved even if Archivelog exists in the ASM diskgroup, then add the following TRANLOGOPTIONS option into Parameter file to find Archivelog in the Oracle ASM Diskgroup.

You should create goldengate user in the ASM Instance to be connected.

 

This is the second case for this error.

TRANLOGOPTIONS ASMUSER goldengate@ASM, ASMPASSWORD goldengate123

 

When I add the following parameter into Parameter file, my problem has been solved.
