Real Application Cluster Acronyms
GCS |
Global Cache Services | in memory database containing current locks and awaiting locks, also known as PCM |
GES |
Global Enqueue Services | coordinates the requests of all global enqueues uses the GCS, also known as non-PCM |
GRD |
Global Resource Directory | all resources available to the cluster (formed and managed by GCS and GES), see GRDfor more details |
GRM |
Global Resource Manager | helps to coordinate and communicate the locks requests between Oracle processes |
GSD |
Global Services Daemon | runs on each node with one GSD process per node. The GSD coordinates with the cluster manager to receive requests from clients such as the DBCA, EM, and the SRVCTL utility to execute administrative job tasks such as instance startup or shutdown. The GSD is not an Oracle instance background process and is therefore not started with the Oracle instance |
PCM (IDLM) |
Parallel Cache Management | formly know as (integrated) Distributed Lock Manager, its another name for GCS |
Resource |
n/a | it is a identifiable entity it basically has a name or a reference, it can be a area in memory, a disk file or an abstract entity |
Resource (Global) |
n/a | a resource that can be accessed by all the nodes within the cluster examples would be the following
Data Buffer Cache Block Transaction Enqueue Database Data Structures |
LVB |
Lock Value Block | contains a small amount of data regarding the lock |
TRFC |
Traffic Controller | controls the DLM traffic between instances (messaging tickets) |
August 2017 Update to E-Business Suite Technology Codelevel Checker (ETCC)
The E-Business Suite Technology Codelevel Checker (ETCC) tool helps you identify application or database tier overlay patches that need to be applied to your Oracle E-Business Suite Release 12.2 system. ETCC maps missing overlay patches to the default corresponding Database Patch Set Update (PSU) patches, and displays them in a patch recommendation summary.
What’s New
ETCC has been updated to include bug fixes and patching combinations for the following recommended versions of the following updates:
- July 2017 Database 12.1.0.2 PSU and Proactive Bundle Patch
- July 2017 Database 11.2.0.4 PSU and Engineered Systems Patch
Obtaining ETCC
We recommend always using the latest version of ETCC, as new bugfixes will not be checked by older versions of the utility. The latest version of the ETCC tool can be downloaded via Patch 17537119 from My Oracle Support.

Can Oracle Label Security be Used with EBS 12.2?
Yes, Oracle Label Security (OLS) can be used with EBS 12.2. It can also be used for earlier EBS releases such as EBS 12.1 and 12.0.
Oracle Label Security is an optional database-level technology for developing customized security schemes. It is possible to use this technology to customize EBS 12.2.
There is no documentation for using this technology with EBS 12.2. The principles described in the following note for EBS 11i are generally-applicable to customizing later EBS releases such as EBS 12.1 and 12.2:
- Enabling Oracle Label Security for Oracle E-Business Suite (Note 234599.1)
What are the support implications of using OLS with EBS?
This is a technology used for customizing EBS. The standard support implications for customizations apply to customizations created with OLS:
