How To Shutdown(stop)/Startup(start) CRS, OHAS, ASM, RDBMS Services on a RAC Cluster or OCI DBCS System

How  To Shutdown(stop)/Startup(start) CRS, OHAS, ASM, RDBMS  Services on a RAC Cluster or OCI DBCS System

I have used below steps to restarting services on GRID in DBCS.

1) Connect to node #1, then please check if the CRS/OHAS & services are enabled to autostart as follow (repeat this step on each node):

# $GRID_ORACLE_HOME/bin/crsctl config crs


2) If not, then you can enable it as follow (repeat this step on each node):

# $GRID_ORACLE_HOME/bin/crsctl enable crs

3) Shutdown the services on each node as follow:

# $GRID_ORACLE_HOME/bin/crsctl stop crs


4) Verify the services were/are down (repeat this step on each node):

# $GRID_ORACLE_HOME/bin/crsctl status resource -t


5) Then start the services on node #1 as follow (only on first node):

# $GRID_ORACLE_HOME/bin/crsctl start crs


6) Wait 1 minute, then validate the services started & diskgroups were mounted (only on first node):

# $GRID_ORACLE_HOME/bin/crsctl status resource -t


7) Then start the services on node #2 as follow:

# $GRID_ORACLE_HOME/bin/crsctl start crs

8) Wait 1 minute, then validate the services started & diskgroups were mounted on node #2:

# $GRID_ORACLE_HOME/bin/crsctl status resource -t


9) If there are more nodes in the RAC, then repeat the same steps (7-8).

 

10) Then check the status of the clusterware globally as follows:

# crsctl check cluster -all

Sample output:

[root@asmnode1 ~]# crsctl check cluster -all

WebLogic migration to OCI using WDT tool

WebLogic migration to OCI using WDT tool Oracle WebLogic Deploy Tool (WDT) is an open-source project designed to simplify and streamline the management of Oracle WebLogic Server domains. With WDT, you can export configuration and application files from one WebLogic Server domain and import them into another, making it a highly effective tool for tasks like migrating on-premises WebLogic configurations to Oracle Cloud. This blog outlines a detailed step-by-step process for using WDT to migrate WebLogic resources and configurations. Supported WLS versions Why Use WDT for Migration? When moving Oracle WebLogic resources from an on-premises environment to Oracle Cloud (or another WebLogic Server), WDT provides an efficient and reliable approach to: Discover and export domain configurations and application binaries. Create reusable models and archives for deployment in a target domain. Key Pre-Requisites Source System: An Oracle WebLogic Server with pre-configured resources such as: Applica...

How to Validate TDE Wallet Password in Oracle Database

How to Validate TDE Wallet Password in Oracle Database Validating the Transparent Data Encryption (TDE) wallet password is crucial, especially when ensuring that the password is correct without using the OPEN or CLOSE commands in the database. This blog post explains a straightforward method to validate the TDE password using the mkstore utility. Steps to Validate TDE Wallet Password Follow these steps to validate the TDE wallet password: Step 1: Copy the Keystore/Wallet File Navigate to your existing TDE wallet directory. Copy only the ewallet.p12 file to a new directory. If a cwallet.sso file exists, do not copy it . The absence of cwallet.sso ensures that the wallet does not use auto-login, forcing the utility to prompt for the password. Step 2: Validate Using mkstore Use the mkstore utility to check the contents of the wallet file. The mkstore utility will prompt you for the TDE wallet password, allowing you to validate its correctness. Command Syntax To display the conten...

Rename a PDB in Oracle Database Multitenant Architecture in TDE and Non TDE Environment

Rename a PDB in Oracle Database Multitenant Architecture I am sharing a step-by-step guide to help you rename a PDB. This approach uses SQL commands. Without TDE or encryption Wallet Initial Check Check the Current Database Name and Open Mode: SQL > SELECT NAME, OPEN_MODE FROM V$DATABASE; NAME OPEN_MODE --------- -------------------- BEECDB READ WRITE List Current PDBs: SQL > SHOW PDBS; CON_ID CON_NAME OPEN MODE RESTRICTED ---------- ------------------------------ ---------- ---------- 2 PDB$SEED READ ONLY NO 3 FUAT READ WRITE NO We need to RENAME FUAT to BEE  Steps to Rename the PDB Step 1: Export ORACLE_SID Set the Oracle SID to the Container Database (CDB): export ORACLE_SID=BEECDB Step 2: Verify Target PDB Name Availability If the target PDB name is different from the current PDB name, ensure no service exists with the target PDB name. Run SQL to Check Exi...
