Customers reflect broadband authentication server, logs, certification is not a single detail and some broadband users are dropped
- processing
1. Check disk space usage
df -h
I found a disk using 100%
2. The analysis found unusually large database log, log-related clean-up
--10G
/u01/app/oracle/diag/tnslsnr/RADIUS1/listener/alert
--400M
/u01/app/oracle/diag/tnslsnr/RADIUS1/listener/trace
--6G
/u01/app/oracle/diag/rdbms/radius/radius/trace
--3G
/u01/app/oracle/diag/rdbms/radius/radius/alert
3. Check the database space usage
select dbf.tablespace_name,
dbf.totalspace
dbf.totalblocks ,
dfs.freespace,
dfs.freeblocks,
round((dfs.freespace / dbf.totalspace) * 100,2)||'%',
from (select t.tablespace_name,
sum(t.bytes) / 1024 / 1024 totalspace,
sum(t.blocks) totalblocks
from dba_data_files t
group by t.tablespace_name) dbf,
(select tt.tablespace_name,
sum(tt.bytes) / 1024 / 1024 freespace,
sum(tt.blocks) freeblocks
from dba_free_space tt
group by tt.tablespace_name) dfs
where trim(dbf.tablespace_name) = trim(dfs.tablespace_name);
users add table space is full.
alter tablespace users add datafile '/home/oradata/radius/radius/users02.dbf' size 4096m autoextend on ;
4. The above processing is completed, authentication log broadband view, details of a single broadband authentication has normally
5. writing shell scripts periodically clear the log
#!/bin/bash
find /u01/app/oracle/diag/tnslsnr/RADIUS1/listener/alert -name 'log_*.xml' -type f -exec rm -f {} \;
cat /dev/null>/u01/app/oracle/diag/tnslsnr/RADIUS1/listener/trace/listener.log
find /u01/app/oracle/diag/rdbms/radius/radius/alert -name 'log_*.xml' -type f -exec rm -f {} \;
cat /dev/null>/u01/app/oracle/diag/rdbms/radius/radius/trace/alert_radius.log
6. Add Scheduled Task
