Oracle error ORA-00353: log partition uption due to GoldenGate extract process problem

A customer told me today that the logs of the slave database of a core database are increasing rapidly. Through checking, alert logs continuously report errors, as shown below:

The code is as follows: Copy code

You can view the following trace information:

The code is as follows: Copy code

I Googled it and found that nothing was actually done... From the time when alert log first reported an error, I suspect it has something to do with the recently deployed goldengate.
Later I searched the keyword ORA-00353 log into uption ogg extract and found that someone on the mos Forum encountered a similar problem, the Post mentioned the use of the following parameters:

The code is as follows: Copy code
TranLogOptions DBLOGREADER
TranLogOptions BUFSIZE 4096000
TranLogOptions DBLOGREADERBUFSIZE 4096000

The environment of this brother is oracle 11.2.0.3 rac, and the ogg version is 11.2.0.1.5;
Finally, it is said that the buffersize and DBLOGREADERBUFSIZE parameters are adjusted to solve this problem. It seems that the solution has not been mentioned yet, but it has not yet appeared.

Considering that this is the Oracle 11.2.0.4 environment, although it is the ASM environment, archiving logs are stored on the local file system.
Check the goldengate extract parameter again:

The code is as follows: Copy code

.....

Because it extracts active uplouard and only extracts archivelog, it is not necessary to add the TranlogOptions DBLOGREADER parameter.
I suspect it is related to this parameter. After blocking this parameter, no error is reported. It seems that this is an unknown bug of GoldengGate!
