Plugging an Unplugged Pluggable Database issue 3

Multitenant Unplug/Plug Best Practices (文档 ID 1935365.1)

1.source 从0419 升级到1019 ，但是datapatch 没有回退0419，导致plug pdb 在target 1019后，数据库无法正常open.

2. 操作步骤如下：（检查cdb 和plug pdb 兼容性，发现一旦不兼容，plug pdb 只能以受限制模式打开，无法使用，解决办法无。怀疑是步骤3 的bug）

source
create pluggable database PIVRSDEV using 'C:\app\oracle\DEV.xml' NOCOPY TEMPFILE REUSE;
alter pluggable database PIVRSDEV open read write instances =all;

sqlplus sys/oracle123@localhost:15301/pivrsdev AS SYSDBA

exec dbms_pdb.describe (‘PDB1_Unplug.xml’, ‘PIVRSDEV’);
 
  --localtion is D:\appOra12c\Administrator\product\12.1.0\dbhome_1\database

step 2:

target

set serveroutput on
 
 begin
  if dbms_pdb.check_plug_compatibility('C:\app\software\PDB1_Unplug.xml','PIVRSDEV') then
    dbms_output.put_line('no violations found');
  else
    dbms_output.put_line('violations found');
  end if;
end;

create table pdb_plug_back as select * from  pdb_plug_in_violations;
delete from  pdb_plug_in_violations;

set linesize 999
set pagesize 999
SELECT name,type, message, action
  FROM pdb_plug_in_violations

report below error .

Applies to:

Oracle Database - Enterprise Edition - Version 12.1.0.1 and later
Information in this document applies to any platform.

Goal

To provide the Multitenant Unplug/Plug Best Practices

Solution

When plugging into a new container a PDB may have violations due to Database version (12.1.0.1 vs 12.1.0.2)

• SQL patch mismatches
• Database parameter mismatches such as character sets or block size

The dbms_pdb.describe and dbms_pdb.check_plug_compatibility APIs can
be used to determine if a given PDB can be plugged in successfully to a
target container.  Here are the steps to invoke dbms_pdb.describe and
dbms_pdb.check_plug_compatibility to investigate this further:

Preparation:

1) Create PDB description XML file for PDB(PDB1) in question:
    exec dbms_pdb.describe (‘PDB1_Unplug.xml’, ‘PDB1’);
2) In the target container environment, check plug compatibility  
begin
  if dbms_pdb.check_plug_compatibility('PDB1_Unplug.xml', ‘PDB1') then
    dbms_output.put_line(‘no violations found');
  else
    dbms_output.put_line(‘violations found');
  end if;
end;
Plugin compatibility issues, if any, will be reported in
pdb_plug_in_violations view

Scenarios:

Scenario 1 – No plug in violations

SQL> BEGIN
  2    IF dbms_pdb.check_plug_compatibility('/tmp/PDBORCL.xml') THEN
  3       dbms_output.put_line('no violations found');
  4    ELSE
  5       dbms_output.put_line('violations found');
  6    END IF;
  7  END;
  8  /
no violations found

PL/SQL procedure successfully completed.

SQL> SELECT type, message, action
  2    FROM pdb_plug_in_violations
  3    WHERE name = 'PDBORCL';

no rows selected

Scenario 2 – SQL patch present in target container but not in source container

SQL> BEGIN
  2    IF dbms_pdb.check_plug_compatibility('/tmp/PDBORCL.xml') THEN
  3       dbms_output.put_line('no violations found');
  4    ELSE
  5       dbms_output.put_line('violations found');
  6    END IF;
  7  END;
  8  /
violations found

SQL> SELECT type, message, action
  2    FROM pdb_plug_in_violations
  3    WHERE name = 'PDBORCL';

TYPE      MESSAGE
--------- --------------------------------------------------------------------------------
ACTION
--------------------------------------------------------------------------------
ERROR      PSU bundle patch 1 (PSU Patch 12345): Installed in the CDB but not in the PDB.

Call datapatch to install in the PDB or the CDB

Scenario 3 – SQL patch present in source container but not in target container

SQL> BEGIN
  2    IF dbms_pdb.check_plug_compatibility('/tmp/PDBORCL.xml') THEN
  3       dbms_output.put_line('no violations found');
  4    ELSE
  5       dbms_output.put_line('violations found');
  6    END IF;
  7  END;
  8  /
violations found

SQL> SELECT type, message, action
  2    FROM pdb_plug_in_violations
  3    WHERE name = 'PDBORCL';

TYPE      MESSAGE
--------- --------------------------------------------------------------------------------
ACTION
--------------------------------------------------------------------------------
ERROR      PSU bundle patch 1 (PSU Patch 12345): Installed in the PDB but not in the CDB.
Call datapatch to install in the PDB or the CDB

Scenario Summary and Actions

Scenario	Recommended Action
1: SQL Patches in both source and target container	None needed – safe to plug in (see Document 1633071.1)
2: SQL Patches in target container only	Run datapatch in target after plug in
3: SQL Patches in source container only	Option 1: Rollback the patch(es) on the source PDB before unplugging % datapatch -rollback < patch id > –force [–bundle_series] -pdbs <pdb1,pdb2,...,pdbn> Option 2: Install the patch(es) on the target installation then run datapatch in target after plug in Note: Option 2 will apply the new patches in the CDB and all PDBs in the target.
