Oracle 11g 11.2.0.1 setting HuagePage causes TRC to increase

Recently, it was found that the size of the sid_ora_xxxx.trc file in the diag/.../trac/directory is 11 mb and the number of similar files is large. As a result, 8 GB hard disk space is occupied.

Another colleague said that his DG had no such problem. They all had the same system and version. The only difference was that he used the file path and I used the single aggregation + ASM.

May I ask whether the maximum available mode of DG in 11.2.0.1 can be recovered in time, and the read-only mode is enabled.
Then I found that *. trc under trac is large. On average, 1 trc has 11 M. It's all about DUMP. Why is this caused? But no other DG will
I did not find the posdb_ora_30275.trc string in ALTER. LOG.

However, it may take one week to complete the recent setup. This problem has not been solved in the last few days. Recently, we have set up HUGEPAGE and SGA_LOCK, and added the system VM settings.

Assume that only HUGEPAGE may be large, so it is canceled.
