Problem description: When building DG, I asked rman to recover from orcl to orclstd database, dup replicated for a long time, and finally an error was reported: ORA-17627: ORA-12577: Message 12577 not found; product=RDBMS; facility=ORA found online The document, it was found that the disk was full, so I solved it.

1.rman target sys/410526@orcl auxiliary sys/410526@orclstd
duplicate target database for standby from active database nofilenamecheck;

The screenshot is not found, but the error is: ORA-17627: ORA-12577: Message 12577 not found; product=RDBMS;

2.orclstd:[root@orclstd dev]# df -h Check that the disk space usage rate of orclstd is as high as 98%.I don’t know what the reason is, please investigate

Filesystem Size Used Avail Use% Mounted on

/dev/sda2 35G 33G 865M 98% /

/dev/sda1 99M 22M 73M 23% /boot

tmpfs 995M 0 995M 0% /dev/shm

3.[root@orclstd /]# du -h --max-depth=1 Check the current disk file usage and found that /u01 has 25G

 4.Follow the path to find and find that there is a monitoring log occupying 2.6G

/u01/app/ Oracle /product/11.2.0/dbhome_1/network/trace/listener.log

5.Delete the monitoring log,

[root@orclstd trace]# rm listener.log

6.Continue to check whether there are other relatively large files, and found that a large number of log.xml files are generated in the alert log

[root@orclstd trace]# cd..

[root@orclstd listener]# ls

alert cdump incident incpkg lck metadata metadata_dgif metadata_pv stage sweep trace

[root@orclstd listener]# cd alert/

[root@orclstd alert]# ls

7.Check the total size, there are about 16 G, which takes up my disk space.I don’t know the reason for the time being, so I delete the.xml first.

[root@orclstd alert]# du -sh

16G.

 8.Delete the log.xml file

[root@orclstd alert]# rm *.xml

rm: remove regular file `log_1000.xml'? ^C

[root@orclstd alert]# rm -f *.xml

8.Check the disk space again, there is a feeling of being released instantly, user% dropped to 44%

df -h

[root@orclstd alert]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/sda2 35G 15G 19G 44% /

/dev/sda1 99M 22M 73M 23% /boot

tmpfs 995M 0 995M 0% /dev/shm

 9.The files from the library have been imported in rman before, so now the orclstd standby library can be started to mount state, now the standby library orclstd is changed to nomount state, and now there is no problem with re-importing rman.

10.I don't know how to generate such a large monitoring file, and the log that may be recorded.I remember that when I started lsnrctl yesterday, I couldn't connect to, and the monitoring process was killed several times in the middle.I don't know if this is the reason.A large number of logs are recorded
