RDBMS and listener log (xml) from SQL*Plus with V$DIAG_ALERT_EXt view [ADR - Automatic Diagnostic Re

With the V$DIAG_ALERT_EXT it is possible to read the logs of all the databases and listeners from the ADR location Great for monitoring. Now only one connection to a database is needed to see all the database alert files and listener logs registered inside the ADR structure.Yes Multiple databases.

There is NO GV$DIAG_ALERT_EXT.

ADR is node, database depended and not global. Still we can use a shared ADR on a shared file system on Oracle CLusterware RAC and then is everthing from one place.

The parameter DIAGNOSTIC_DEST represents the root for the Automatic Diagnostic Repository (ADR), which includes the alertfile states. If this parameter is not set and the ORACLE_BASE is than it will use this information for the DIAGNOSTIC_DEST. If ORACLE_BASE is not set then the ADR root is in log Oracle release 11.2 has introduced new v$ diagnostic (diag) views.

XML markup V$DIAG_ALERT_EXT

The V$DIAG_ALERT_EXT read the log.xml file from de ADR location. Here are sample queries using XML markup with V$DIAG_ALERT_EXT info from ( Marco Gralike ) view sourceprint?01 set pagesize 120
set linesize 200
set long 99999
column ADR_HOME format a40
column "mylog.xml" format a180

select
xmlelement(noentityescaping "msg",
xmlattributes( alt.originating_timestamp as "time",
alt.organization_id as "org_id",
alt.component_id as "comp_id",
alt.message_id as "msg_id",
alt.message_type as "type",
alt.message_group as "group",
alt.message_level as "level",
alt.host_id as "host_id",
alt.host_address as "host_addr",
alt.process_id as "pid_id",
alt.version as "version"
),
xmlelement("txt", message_text)
) as "mylog.xml"
from
v$diag_alert_ext alt order by alt.component_id, alt.inst_id, alt.originating_timestamp

Most of the "normal errors", if such thing exists, are level 16. Data mining through the V$DIAG_ALERT_EXT table is now possible. Good thing is that there are errors for the component "tnslsnr", which means that it is now possible to catch Oracle*Net errors, too. Maybe in release 12C Oracle has made this complet functional, now it is a hidden not described structure.
Summary:
V$DIAG_ALERT_EXT (X$DBGALERTEXT) is done by External table referencing log*.xml files. Effectively indexed by alert date, so date-based queries are “efficient and performant.” (MOS Doc ID 961682.1) Has inst_id column, but not RAC-aware. As of 11.2, V$DIAG_ALERT_EXT Includes alerts from all ADR homes (ASM, listeners, clients, etc.) SQLPLUS statements view sourceprint?1 select ORIGINATING_TIMESTAMP, MESSAGE_TEXT
from V$DIAG_ALERT_EXT
WHERE ORIGINATING_TIMESTAMP > systimestamp - INTERVAL ‘15‘ minute
and trim(COMPONENT_ID)=‘rdbms‘
and inst_id=1
order by originating_timestamp;
