用途
此文件是一個對 12c Grid Infrastructure 的新功能：管理資料庫的 FAQ 文件。
問題和答案
什麼是管理資料庫？
管理資料庫是一個由 12c 叢集軟體管理的單例項資料庫。因為此資料庫為單例項資料庫，所以它只在叢集的一個節點執行。也正是因為這個資料庫是被叢集管理的，所以如果資料庫執行節點 down 掉，資料庫也會被自動切換到另外的節點。
管理資料庫是用來幹什麼的？
在 12c，管理資料庫是一個用來集中存放 Cluster Health Monitor 資料（又稱：CHM/OS，ora.crf）以及其他的資料的資料庫。
管理資料庫的資料檔案放在哪裡？
在12.1版本，管理資料庫預設和 OCR、Voting disk 使用一樣的共享儲存。在12.2，在安裝時可以指定使用單獨的diskgroup。
在安裝升級的時候，如果不配置管理資料庫會有什麼樣的問題？
管理資料庫在 12.1是非強制的，如果在使用 OUI 安裝升級的時候未選擇該選項，所有的依賴於管理資料庫的功能都會被禁用（比如 CHM/OS 等等）。
在 12.1.0.2 中，管理資料庫變為強制安裝(除了 Exadata環境)。
有哪些和管理資料庫相關的資源？
從“crsctl stat res –t”的輸出結果來看，以下是和管理資料庫有關的資源：
ora.mgmtdb
1 ONLINE ONLINE racnode1f Open,STABLE
ora.MGMTLSNR
1 ONLINE ONLINE racnode1f 169.254.118.96 10.3.0.70,STABLE
在 OS 層面，可以看到資料庫“-MGMTDB”和監聽器“MGMTLSNR”：
ps -ef| grep pmon_-MGMTDB
grid 3500 1 0 Jun04 ? 00:06:18 mdb_pmon_-MGMTDB
ps -ef| grep MGMTLSNR
grid 3308 1 0 Jun04 ? 00:00:55 /ocw/c101/bin/tnslsnr MGMTLSNR -no_crs_notify -inherit
如果管理資料庫停掉，怎樣手工啟動？
管理資料庫被叢集管理而且應該一直執行。如果資料庫因為一些原因停掉，下面的 srvctl 命令可以用來啟動資料庫：
Usage: srvctl start mgmtdb [-startoption <start_option>] [-node <node_name>]
Usage: srvctl start mgmtlsnr [-node <node_name>]
怎樣“cd”到管理資料庫的子目錄去檢視跟蹤檔案？
通常來講，一般沒有必要去檢視管理資料庫的跟蹤檔案。如果需要檢視則必須在資料庫名前加上“./”以避免以下的錯誤，因為資料庫資料庫名前面有個“-”：
cd -MGMTDB
-bash: cd: -M: invalid option
cd: usage: cd [-L|-P] [dir]
cd
./
-MGMTDB ==>> this will work as "./" is specified
more -MGMTDB_m000_9912.trc
more: unknown option "-M"
usage: more [-dflpcsu] [+linenum | +/pattern] name1 name2 ...
more
./
-MGMTDB_m000_9912.trc

Oracle Database 12c Enterprise Edition Release 12.1.0.1.0 - 64bit Production
With the Partitioning, Automatic Storage Management, Advanced Analytics and Management Database options
有沒有必要去手動備份或優化資料庫？
目前沒有必要。
在Oracle Restart環境下，GIMR會被預設建立嗎？
不。在Oracle Restart環境下GIMR預設不會被建立。
需要分配多少磁碟空間給資料庫？
OCR 和管理資料庫在外部冗餘的情況下：
至少 5.2GB 的空間的 OCR 用來儲存資料庫（4.5GB+300MB Voting files+400MB OCR），如果節點數超過 4，則每個多出的節點多分配 500MB 的空間。 如：一個六節點的叢集應該使用 6.2GB 空間。

適用於:
Oracle Database - Enterprise Edition - 版本 12.2.0.1 和更高版本
本文件所含資訊適用於所有平臺
目標
本文概括了建立 12.2 GIMR (GridInfrastructure Management Repository) Database (MGMTDB) 的步驟。
解決方案
1. 發出 DBCA 命令來建立 MGMTDB 的 container。
以 grid 使用者，
$ <GI_HOME>/bin/dbca -silent -createDatabase -createAsContainerDatabase true -templateName MGMTSeed_Database.dbc
-sid -MGMTDB
-gdbName _mgmtdb
-storageType ASM
-diskGroupName
<DG target>
-datafileJarLocation <GI_HOME>/assistants/dbca/templates
-characterset AL32UTF8
-autoGeneratePasswords
-skipUserTemplateCheck
注意，根據需要修改<DG target> （比如 +DATA, +REDO, ...）
2. 建立 pluggable GIMR 庫。
以 grid 使用者，
$ <GI_HOME>/bin/mgmtca -local
注意，為了避免使用上述的手工步驟，您可以利用自動化工具 ： mdbutil.pl ，請參閱 Note: 2065175.1
舉例如下：
(oracle)$ ./mdbutil.pl --addmdb --target=+DATAC1
2017-04-04 14:47:48: I Starting To Configure MGMTDB at +DATAC1...
2017-04-04 14:47:57: I Container database creation in progress...
2017-04-04 14:55:20: I Plugable database creation in progress...
2017-04-04 14:57:03: I Executing "/tmp/mdbutil.pl --addchm" on xxxadm01 as root to configure CHM.

適用於:
Oracle Database - Enterprise Edition - 版本 12.1.0.1 到 12.2.0.1 [發行版 12.1 到 12.2]
本文件所含資訊適用於所有平臺
目標
本文目的給出轉移 12c 的 GIMR（Grid Infrastructure Management Repository）到其它共享儲存的概要步驟。
對於12.2 請參考 note 2065175.1 - MDBUtil: GI Management Repository configuration tool 來建立GIMR或者移動資料檔案到不同的磁碟組上。這篇文件的內容同樣適用於在12.2 上刪除已經存在的mgmtdb和建立新的mgmtdb
這個過程執行時GIMR 管理資料庫中原有的資料無法保留。請通過 grid 使用者，在任何節點執行下面命令，以手動方式備份“管理資料庫”：
$ <GI_HOME>/bin/oclumon dumpnodeview -allnodes -v > <backup-file>
解決方案
1. 停止並禁用 ora.crf 資源
需要使用 root 使用者，在每一個節點執行命令：
# <GI_HOME>/bin/crsctl stop res ora.crf -init
# <GI_HOME>/bin/crsctl modify res ora.crf -attr ENABLED=0 -init
不要停止 ora.mgmtlsnr 資源 ora.mgmtdb，否則第二步會遇到下面錯誤：
Oracle Grid Management database is running on node "". Run dbca on node "" to delete the database.
2. 執行 DBCA 命令刪除管理資料庫
使用 grid 使用者執行下面命令，來確定 MGMTDB 執行的節點：
$ <GI_HOME>/bin/srvctl status mgmtdb
在MGMTDB執行的節點上，執行以下命令：
$
<GI_HOME>/bin/dbca -silent -deleteDatabase -sourceDB -MGMTDB

注意：
如果管理MGMTDB庫沒有執行，DBCA 會遇到下面錯誤：
Oracle Grid Management database is running on node "". Run dbca on node "" to delete the database.
解決該問題的辦法是通過下面方式手動刪除：
- 在檔案系統層面，刪除管理資料庫的相關檔案。並刪除 oratab 的相關條目
- 使用 srvctl 刪除 mgmtdb 資源：srvctl remove mgmtdb
3. 重建管理資料庫（MGMTDB）
3A. 針對 12.1.0.1 版本
在任一節點使用 grid 使用者執行 DBCA 命令：
$
<GI_HOME>/bin/dbca -silent -createDatabase -templateName MGMTSeed_Database.dbc -sid -MGMTDB -gdbName _mgmtdb -storageType ASM -diskGroupName <+NEW_DG> -datafileJarLocation <GI_HOME>/assistants/dbca/templates -characterset AL32UTF8 -autoGeneratePasswords -oui_internal

注意：無論是新建立還是修改磁碟組的過程，我們都建議把磁碟組的引數 compatible.asm 和 compatible.rdbms 設定成 12.1。
以上例子是建立了管理資料庫到一個新的磁碟組，如果是使用共享的 NFS/CFS， 請參考以下例子：
<GI_HOME>/bin/dbca -silent -createDatabase -templateName MGMTSeed_Database.dbc -sid -MGMTDB -gdbName _mgmtdb -storageType FS -datafileDestination <NFS_Location> -datafileJarLocation <GI_HOME>/assistants/dbca/templates -characterset AL32UTF8 -autoGeneratePasswords -oui_internal
3B. 針對 12.1.0.2 版本
a. 在任一節點使用 grid 使用者執行 DBCA 命令，並指定好期望使用的磁碟組名：
$ <GI_HOME>/bin/dbca -silent -createDatabase -sid -MGMTDB -createAsContainerDatabase true -templateName MGMTSeed_Database.dbc -gdbName _mgmtdb -storageType ASM -diskGroupName <+NEW_DG> -datafileJarLocation $GI_HOME/assistants/dbca/templates -characterset AL32UTF8 -autoGeneratePasswords -skipUserTemplateCheck

Ex: CREATE DISKGROUP … ATTRIBUTE 'compatible.rdbms' = '12.1', 'compatible.asm' = '12.1';
管理資料庫可以通過下面命令，從 NFS/CFS 遷移到 ASM 磁碟組：
$ <GI_HOME>/bin/dbca -silent -createDatabase -sid -MGMTDB -createAsContainerDatabase true -templateName MGMTSeed_Database.dbc -gdbName _mgmtdb -storageType FS -datafileDestination <NFS_Location> -datafileJarLocation $GI_HOME/assistants/dbca/templates -characterset AL32UTF8 -autoGeneratePasswords -skipUserTemplateCheck
b. 使用 DBCA 再建立一個 PDB：
使用 grid 使用者執行下面 DBCA 命令：
注意：命令中的 CLUSTER_NAME 中不可以有中橫線(“-“)，需要使用下劃線替代(“_”)。
$ <GI_HOME>/bin/dbca -silent -createPluggableDatabase -sourceDB -MGMTDB -pdbName <CLUSTER_NAME> -createPDBFrom RMANBACKUP -PDBBackUpfile <GI_HOME>/assistants/dbca/templates/mgmtseed_pdb.dfb -PDBMetadataFile <GI_HOME>/assistants/dbca/templates/mgmtseed_pdb.xml -createAsClone true

4. 確保管理資料庫建立成功
使用grid 使用者，檢查管理資料庫執行在哪個節點：
$ <GI_HOME>/bin/srvctl status MGMTDB
Database is enabled
Instance -MGMTDB is running on node <NODE_NAME>
On <NODE_NAME>:
$ <GI_HOME>/bin/mgmtca
5. 啟用並啟動 ora.crf 資源
使用root 使用者在每一個節點執行：
# <GI_HOME>/bin/crsctl modify res ora.crf -attr ENABLED=1 -init
# <GI_HOME>/bin/crsctl start res ora.crf -init

CAUSE
Issue was investigated in:
Bug 23563549 - -MGMTDB SYSMGMTDATA IS FILLING UP WHICH CAUSES GRID1 DISK TO REACH 100%.
Bug 24331121 - OCR_VOTE DISK GROUP IS 99% FULL, HIGH UNDO USED BY MGMTDB
The cause is due to autoextend for the tablespace being set to on.
SOLUTION
Solution 1:
Recreate GIMR which will drop the existing database and set autoextend back to off.
note 1589394.1 - How to Move/Recreate GI Management Repository to Different Shared Storage (Diskgroup, CFS or NFS etc)
Or
Solution 2:
Manually perform the following steps to shrink:
1. Stop and disable ora.crf resource.
On each node, as root user:
# <GI_HOME>/bin/crsctl stop res ora.crf -init
# <GI_HOME>/bin/crsctl modify res ora.crf -attr ENABLED=0 -init
2. Identify huge objects from dba_segments and truncate them:
Connect to MGMTDB:
export ORACLE_HOME=<GRID_HOME>
export ORACLE_SID=-MGMTDB
$ORACLE_HOME/bin/sqlplus / as sysdba
SQL> select pdb_name from dba_pdbs where pdb_name!='PDB$SEED';
PDB_NAME
--------------------------------------------------------------------------------------------------------------------------------
CEHAOVMSP1CLU68 ====>>>> this is your PDB name, use it in next command
SQL> alter session set container=CEHAOVMSP1CLU68;
Session altered.
SQL> col obj format a50
SQL> select owner||'.'||SEGMENT_NAME obj, BYTES from dba_segments where owner='CHM' order by 2 asc
Likely you are going to see the following as the biggest table:
CHM.CHMOS_PROCESS_INT_TBL
CHM.CHMOS_DEVICE_INT_TBL
Truncate the table, i.e.:
SQL> truncate table CHM.CHMOS_PROCESS_INT_TBL;
SQL> truncate table CHM.CHMOS_DEVICE_INT_TBL;
..
3. Shrink the tablespace:
https://docs.oracle.com/database/121/ADMIN/schema.htm#ADMIN11600
4. Enable and start ora.crf resource.
On each node, as root user:
# <GI_HOME>/bin/crsctl modify res ora.crf -attr ENABLED=1 -init
# <GI_HOME>/bin/crsctl start res ora.crf -init

DETAILS
Grid Infrastructure Management Repository (GIMR) database MGMTDB
The Grid Infrastructure Management Repository enables such features as Cluster Health Monitor, Oracle Database QoS Management, and Rapid Home Provisioning, and provides a historical metric repository that simplifies viewing of past performance and diagnosis of issues.
During the installation of Oracle Grid Infrastructure 12.1.0.1 you've had the option to install the Grid Infrastructure Management Repository (GIMR) database MGMTDB. Starting with Oracle Grid Infrastructure 12.1.0.2 the GIMR database has become mandatory and is automatically installed.
MDBUtil: GI Management Repository configuration tool
If you need to create or re-create the Grid Infrastructure Management Repository (GIMR) database MGMTDB after the installation, specific knowledge and many manual steps are required. (see Note 1589394.1 for details). You also may desire to move the MGMTDB database files to a different disk group from your Clusterware files. MDBUtil has been created to provide this functionality in one simple command.
Note:
This script is provided for educational purposes only.
It is NOT supported by Oracle World Wide Technical Support.
The script has been tested and appears to work as intended.
You should always run new scripts on a test instance initially.
