Alter system set events '10298 trace name context forever, level 32'

You do not need to restart the database to execute this command, but it becomes invalid after the next database restart. You need to manually execute it again.

If you want to automatically execute this command after the database is restarted, run the following command:

Today in the virtual machine environment experiment, when changing the RAC environment to flashback on, reported a ORA-27054 error, the error code is as follows:

Errors in file/u01/app/oracle/admin/racdb/udump/racdb2_ora_25551.trc:
ORA-38701: Flashback database log 2 seq 1 thread 2: "/u01/flashback/RACDB/flashback/o1_mf _ % u _. flb"
ORA-27054: NFS file system where the file is created or resides is not mounted with correct options

From the error description, we can see that the flashback directory is implemented through the nfs file system. When the system mounts nfs, the incorrect parameter option is used, resulting in an oracle error. Check online information and solve the problem through document 359515.1.

* NFS mount option "forcedirectio" is required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428)
** AIX is only supported with NAS on AIX 5.3 TL04 and higher with Oracle 10.2.0.1 and later (NetApp)
* ** NAS devices are only supported with HPUX 11.23 or higher ONLY

# These mount options are for Linux kernels 2.6 and above for older kernels please check Note 279393.1

Due to Unpublished bug 5856342, it is necessary to use the following init. ora parameter when using NAS
With all versions of RAC on Linux (x86 & X86-64 platforms) until 10.2.0.4. This bug is fixed and pinned in 10.2.0.4 patchset.
