Stop AWS RDS instance using the CLI

-
The easiest method to start/stop AWS RDS instance based on schedule is by using AWS CLI inside a bash/bat script.

Download and configure the AWS CLI.

Install AWS CLI – https://docs.aws.amazon.com/cli/latest/userguide/install-windows.html
Configure AWS CLI for the VPC – https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html

CLI Commands.

Use “rds stop-db-instance” and “rds start-db-instance” commands in a simple bat file as below,
 set userprofile=C:\Users\07766  
 aws rds stop-db-instance --db-instance-identifier qa-rds-ban
 aws rds stop-db-instance --db-instance-identifier dev-rds-ban
 aws rds stop-db-instance --db-instance-identifier uat-rds-ban
It is required to set the userprofile of the user who configured the AWS CLI in the bat script
set userprofile=C:\Users\<username>
If you have not configured the AWS CLI using the security parameters, it is required to add below configuration to the script,
        aws configure set AWS_ACCESS_KEY_ID <access_key>
        aws configure set AWS_SECRET_ACCESS_KEY <secret_key>
        aws configure set default.region <region>
Once the bat file is ready simple windows task scheduler would do the trick.

Limitations

This is just a simple script to start/stop rds instance on a particular time. There is no verification mechanism included in the script, which can be added by using the rds describe-db-instances command.
e.g - aws rds describe-db-instances --db-instance-identifier qa-rds-mob-ban --no-verify-ssl | findstr "DBInstanceStatus"

ORA-16433: The database or pluggable database must be opened in read/write

-

ORA-16433 is an error returned when a database cannot be opened. This can be a result of multiple conditions including, The inconsistency of the database Physical corruption Loss of dependent files or access issues etc.. More often than not the solution is to recover from available backups, but there can be situations where backups are not available, specially on UAT or Test setups. Although not the ideal scenario, in this type of situation you might want to open the databases even with inconsistency.  In Comes --> _ALLOW_RESETLOGS_CORRUPTION First, if you are in a position to use _ALLOW_RESETLOGS_CORRUPTION=TRUE, that means it has to be a critical moment, and when you come across more ora- errors while you are trying to reopen the databsae, that can be annoying. Note - _ALLOW_RESETLOGS_CORRUPTION=TRUE must only be used after Oracle support confirmation as a last resort. Also make sure to take cold backup before proceeding. Basic steps to be followed to resolve ORA 16433 after

Oracle Multitenant - Create new service for PDB using DBMS_SERVICE

-
Image
When an Oracle PDB is created it starts up a default service with the PDB name. For direct connections to    PDB this service can be used. But there are situations where new service name is required in PDB level, common example is after a PDB restoration/clone, in order to enable application connections without changes in connection string. Setting service_names parameter in PDB level is not possible hence it is not an option in multitenant setup.

Wait for unread message on broadcast channel - Blocking Sessions

What is Wait for unread message on broadcast channel wait event? Wait for unread message on broadcast channel is a wait event where source destination communication is involved and the database is waiting for a reply from remote party. Mostly this wait is seen related to data pump export (expdp) or import (impdp) operations. Although categorized in idle wait class "Wait for unread message on broadcast channel" can become the blocking session for some other sessions. Common causes for stuck sessions waiting on this wait event includes, Broken databases links, where remote database is not responding. Abnormally killed remote processes causing the sessions to wait. When a session is waiting on "Wait for unread message on broadcast channel" it can become a blocking session for dependent sessions. Most probably these sessions will be waiting on "library cache pin" or related concurrency wait events. The blocking_session column of (g)v$session view
