SRDC - ORA-1552: Checklist of Evidence to Supply (Doc ID 1681333.1)

Action Plan

1. Execute srdc_db_undo_config.sql  as sysdba and provide the spool output  以sysdba身份执行脚本

--srdc_db_undo_config.sql

REM srdc_db_undo_config.sql 
REM collect Undo parameters,segment and transaction details for troubleshooting high Undo space usage issues
define SRDCNAME='DB_Undo_Space'
set pagesize 200 verify off sqlprompt "" term off entmap off echo off
set markup html on spool on
COLUMN SRDCSPOOLNAME NOPRINT NEW_VALUE SRDCSPOOLNAME
select 'SRDC_'||upper('&&SRDCNAME')||'_'||upper(instance_name)||'_'|| to_char(sysdate,'YYYYMMDD_HH24MISS') SRDCSPOOLNAME from v$instance;
spool &&SRDCSPOOLNAME..htm
select 'Diagnostic-Name : ' "Diagnostic-Name ", '&&SRDCNAME' "Report Info" from dual
union all
select 'Time : ' , to_char(systimestamp, 'YYYY-MM-DD HH24MISS TZHTZM' ) from dual
union all
select 'Machine : ' , host_name from v$instance
union all
select 'Version : ',version from v$instance

select 'DBName : ',name from v$database

set echo on

from x$ksppi a, x$ksppcv b, x$ksppsv c

2. If the error is reproducible:   如果错误是可重现的

SQL> conn user/pass
SQL> ALTER SESSION SET EVENTS '1552 trace name errorstack level 3';
SQL> ALTER SESSION set MAX_DUMP_FILE_SIZE= unlimited ;
SQL> ALTER SESSION set TIMED_STATISTICS = true;
SQL> ALTER SESSION set TRACEFILE_IDENTIFIER = "ORA-1552";
SQL> Reproduce the error  --重现错误

SQL> ALTER SESSION SET EVENTS '1552 trace name errorstack off';

Then upload resulting tracing in the directory specified by user_dump_dest  or the diagnostic_dest parameter .

然后将结果跟踪上传到user_dump_dest或diagnostic_dest参数指定的目录中

3. If the error is not reproducible:  如果错误无法重现

SQL> CONN / AS SYSDBA
SQL> ALTER SYSTEM SET EVENTS '1552 trace name errorstack level 3';
SQL> ALTER SYSTEM set MAX_DUMP_FILE_SIZE= unlimited ;
SQL> ALTER SYSTEM set TIMED_STATISTICS = true;

Wait until the error (ORA-1552) occurs again .  --等待直到再次出现错误（ORA-1552）

Note When the ALTER SYSTEM SET EVENTS command is used only new sessions see the events set by this command.
--注意当仅使用ALTER SYSTEM SET EVENTS命令时，新的会话将看到此命令设置的事件

SQL> ALTER SYSTEM SET EVENTS '1552 trace name errorstack off';

Then upload resulting tracing in the directory specified by user_dump_dest  or the diagnostic_dest parameter .

然后将结果跟踪上传到user_dump_dest或diagnostic_dest参数指定的目录中

4. Attach all of the above evidence to the Service Request at SR creation time. The evidence can all be placed into a single ZIP or similar compressed archive or can be attached as separate files.

4. 在创建SR时，将以上所有证据附加到服务请求中。证据可以全部放入单个ZIP或类似的压缩档案中，也可以作为单独的文件附加
