RAC DB startup issue after Hugepages changed

-
Faced an issue after changing the DB memory parameters as suggested by DBA.
The DB is a RAC DB and after the Parameters were changed, Only 1 Node came UP and Node2 failed to start with the below error:

             "ORA-27106: system pages not available to allocate memory
              Additional information: 6048
              Additional information: 1"

Unable to fix it and requested DBA to look into it.


Issue: As part of Parameter changes, we changed the "USE_LARGE_PAGES" setting to "ONLY"

Solution: USE_LARGE_PAGES was be set to "ONLY".After reverting back "USE_LARGE_PAGES" parameter value to "TRUE" DB came up.

In my earlier post (OCI -Part1 ), we have gone through OCI basic details, let's dive deep more into it. Before that, we need to u nderstand the following concepts and terminology to help you get started with Oracle Cloud Infrastructure.  Note: OCI is re-branding of Bare Metal Cloud Service (BMCS) BARE METAL HOST Oracle Cloud Infrastructure provides you control of the physical host (“bare metal”) machine. Bare metal compute instances run directly on bare metal servers without a hypervisor. When you provision a bare metal compute instance, you maintain sole control of the physical CPU, memory, and network interface card (NIC). You can configure and utilize the full capabilities of each physical machine as if it were hardware running in your own data center. You do not share the physical machine with any other tenants. REGIONS AND AVAILABILITY DOMAINS  Oracle Cloud Infrastructure is physically hosted in regions and availability domains. A region is a localized geographic area, an...

Sometimes users start working and then forget which EnterpriseOne environment they are logged into. Can you tell which environment you are logged into? Luckily, there is a new UDC that allows you to change your EnterpriseOne environment color. You can now set up environments to be color-coded for when you need a clear visual distinction as to which environment you are logged into. This enables you to quickly identify the non-production environments by color. The new UDC is 98/CO and is available in EnterpriseOne Tools Release 9.2.4 with Applications Release 9.1 and 9.2. The image below shows the default EnterpriseOne environment color. However, you can easily change the color to reflect different environments. For example, DV could be red, PY could be green, and PD could be yellow, as shown below. To do so, just add a new row in the User Defined Codes section, enter the EnterpriseOne environment name and the HEX value of the color you want the environment to be, and ...
