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.

ASM TNS Alias details are as follows. You should add the ASM Instance TNS entry to the tnsnames.ora as follows.

ASM =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.63.34 )(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = +ASM)
)
)

If your problem is not related with the ASM Instance and TRANLOGOPTIONS ASMUSER don’t solve your problem, then check the following case.

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.

https://ittutorial.org/oracle-rman-recovery-manager-restore-recover-tutorials-5-restore-tablespace-archivelog-and-datafile/

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

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.
