升级psu引发的新bugORACLE ORA-07445

原创 Oracle 作者:pingdanorcale 时间:2020-04-27 09:03:42 0 删除 编辑

最近客户在打10.2.0.5.19 PSU补丁,运行@catbundle.sql psuapply,报ORA-07445:exception encountered: core dump[joet_create_root_thread_group()+140] [SIGSEGV] [Address not mapped to object] [0x000000008][] []错误。导致升级无法进行下去。

   查看相关文档,只显示如下信息:


  没有其他方案,只能备份数据库,来尝试上边的方案,但是在逻辑备份时同样遇到上边的错误。无奈只能使用rman进行备份。

 根据1940340.1这个文档上的说可能是在应用PSU是导致的oracle buf。

  按照步骤如下:

 Create pfile=’/home/oracle/pfie.ora’ fromspfile ;\

SQL> alter system set java_jit_enabled =FALSE; ---10g 不需要

  SQL> alter system set"_system_trig_enabled"=FALSE;---

  SQL> alter system setJOB_QUEUE_PROCESSES=0;


SQL> startup restrict

 

SQL> @catbundle.sql psu apply –跑完还原参数
 

SQL> alter system set"_system_trig_enabled"=TRUE;

SQL> alter system setJOB_QUEUE_PROCESSES=10;

重启数据库。

以上方案直供参考。

参考1940340.1文档

SYMPTOMS

ORA-07445: exception encountered: core dump [joet_create_root_thread_group()+145] is seen at startup.

The issue happens in CDC environments and the following statement is seen in the alert log:

----- Current SQL Statement for this session (sql_id=f03bykh6st1m5) -----
BEGIN
      /* NOP UNLESS A TABLE OBJECT */
      IF dictionary_obj_type = 'TABLE'
      THEN
        sys.dbms_cdc_ipublish.change_table_trigger(dictionary_obj_owner,dictionary_obj_name,sysevent);
      END IF;
      END;
----- PL/SQL Stack -----
----- PL/SQL Call Stack -----
  object      line  object
  handle    number  name
0xa7dd71c0        12  package body SYS.DBMS_CDC_IPUBLISH

 

The error can also be seen from MMON_SLAVE with an action of : JAVAVM JIT slave action without any SQL statement referenced.

The call stack is:

joet_create_root_th <- read_group <- joet_aux_thread_mai
        <- seoa_note_stack_out <- side <- joet_thread_main <- sjontlo_initialize <- joe_enter_vm
         <- ioei_execute <- ioesub_EXECUTE <- seoa_note_stack_out <- side <- ioe_execute
          <- side <- jox_ioe_execute <- joxgrovel_jitsomeme <- thods <- joxgroveldrv
           <- thods <- joxjitexe <- joxrdp_ <- joxrdp <- kebm_slave_main
            <- ksvrdp <- opirip <- opidrv <- sou2o <- opimai_real
             <- ssthrdmain <- main <- libc_start_main <- start

joet_create_root_thread_group <- joet_aux_thread_main
        <- seoa_note_stack_outside <- joet_thread_main <- sjontlo_initialize <- joe_enter_vm
       

CHANGES

Apply Patch 19791427 : COMBO OF OJVM COMPONENT 11.2.0.3.1 DB PSU + DB PSU 11.2.0.3.12 (OCT2014)    

OR

Patch 19282015: ORACLE JAVAVM COMPONENT 11.2.0.3.1 DATABASE PSU (OCT2014) +
Patch 19121548: DATABASE PATCH SET UPDATE 11.2.0.3.12 (INCLUDES CPUOCT2014)

OR ONLY 

Patch 19282015 "ORACLE JAVAVM COMPONENT 11.2.0.3.1 DATABASE PSU (OCT2014)

CAUSE

 The cause is a problem within the Patch and it is investigated by Development in active bugs:

BUG 19904315  - RECEIVE ORA-07445[JOET_CREATE_ROOT_THREAD_GROUP()] AFTER APPLYING PATCH 19791427

Bug 19838078  - ORA-7445 [JOET_CREATE_ROOT_THREAD_GROUP()+136] ON SMON CACHE RECOVERY

SOLUTION

 To workaround this issue perform the next steps:

 

1/ Apply patch 19791427 or Patch 19282015 till the end of Installation steps and 3.3.1.

2/ Before running Postinstallation step (3.3.2), set the following init parameters so that JIT and job process do not start.

If spfile is used:

SQL> alter system set java_jit_enabled = FALSE;
SQL> alter system set "_system_trig_enabled"=FALSE;
SQL> alter system set JOB_QUEUE_PROCESSES=0;

3/ Startup instance in restricted mode and run postinstallation step.

SQL> startup restrict

4/ Run Postinstallation steps (3.3.2)

5/ Reset modified init parameters
SQL> alter system set java_jit_enabled = true;
SQL> alter system set "_system_trig_enabled"=TRUE;
SQL> alter system set JOB_QUEUE_PROCESSES=10;
        -- or original JOB_QUEUE_PROCESSES value

5/ Restart instance as normal
