2. Analyze the table using srdc_db_analyze_table.sql (for non partitioned tables) or srdc_db_analyze_partition.sql (for partitioned tables). Upload the spool output.
2. 使用 srdc_db_analyze_table.sql (用于非分区表)或 srdc_db_analyze_partition.sql (用于分区表)分析表

3. If the error is reproducible: 如果错误是可重现的
Set the follwing traces: 设置以下跟踪
SQL> conn / as sysdba SQL> ALTER SESSION SET EVENTS ‘1555 trace name errorstack level 12‘; SQL> ALTER SESSION SET EVENTS ‘10442 trace name context forever, level 10‘; SQL> ALTER SESSION set MAX_DUMP_FILE_SIZE= unlimited ; SQL> ALTER SESSION set TIMED_STATISTICS = true; SQL> ALTER SESSION set TRACEFILE_IDENTIFIER = "ORA-1555"; ... Reproduce the error --重现错误 SQL> ALTER SESSION SET EVENTS ‘1555 trace name errorstack off‘; SQL> ALTER SESSION SET EVENTS ‘10442 TRACE NAME CONTEXT OFF’;
Then upload the resulting trace file from the directory specified by user_dump_dest or the diagnostic_dest parameter .
4. If the error is not reproducible: 如果错误无法重现
Set the follwing traces:
SQL> CONN / AS SYSDBA SQL> ALTER SYSTEM SET EVENTS ‘1555 trace name errorstack level 12‘; SQL> ALTER SYSTEM SET EVENTS ‘10442 trace name context forever, level 10‘; SQL> ALTER SYSTEM set MAX_DUMP_FILE_SIZE= unlimited ; SQL> ALTER SYSTEM set TIMED_STATISTICS = true; Wait until the error (ORA-1555) occurs again . --等待直到再次出现错误(ORA-1555) Note: When the ALTER SYSTEM SET EVENTS command is used , only new sessions will be impacted by the events set by this command. --注意:使用ALTER SYSTEM SET EVENTS命令时,此命令设置的事件只会影响新的会话 SQL> ALTER SYSTEM SET EVENTS ‘1555 trace name errorstack off‘;
Then upload the resulting trace file from the directory specified by user_dump_dest or the diagnostic_dest parameter .
5. 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.
