2.2.1.8 Disable a Service
Exascale system components are implemented using a series of software services.
Typically, the Exascale cluster automatically contains the required Exascale storage services. However, as an Exascale administrator, you may occasionally need to disable a software service instance.
To disable an Exascale storage service, use the ESCLI chservice
command with the --disable
option.
A disabled service instance is stopped and prevented from automatically restarting on the associated server. To enable a disabled service instance, you must start it manually.

To disable an Exascale storage service on an Exadata storage server, the command syntax is:
@> chservice --attributes name=service_cell --disable
To identify the service instance you want to disable on an Exadata storage server, specify the
name
attribute using the format:name=service_cell
.In the attribute value:
-
service: Specifies the service that you want to act on, which is one of the following:
-
egs
: Specifies the Exascale cluster service, also known as Exascale global service (EGS). -
ers
: Specifies the Exascale control service, also known as Exascale RESTful service (ERS). -
syseds
: Specifies the system vault manager service. -
usreds
: Specifies the user vault manager service. -
bsm
: Specifies the block store manager service. -
bsw
: Specifies the block store worker service.
-
-
cell: Specifies the name of the storage server (
cell
) that hosts the service.The cell must be identified by its name. Use the
lscell
command to find all cell names.

-
To disable an Exascale storage service on an Exadata compute server, the command syntax is:
@> chservice --attributes name=service_compute --disable
To identify the service instance you want to disable on an Exadata compute server, specify the
name
attribute using the format:name=service_compute
.In the attribute value:
-
service: Specifies the service that you want to act on, which is one of the following:
-
egs
: Specifies the Exascale cluster service, also known as Exascale global service (EGS). -
bsw
: Specifies the block store worker service.
-
-
compute: Specifies the name of the compute server (
dbserver
) that hosts the service.Depending on the required service location, specify either the name of a specific compute node virtual machine (VM) or the Exadata compute node host domain (KVM host or Dom0).
-
You can also add the --force
option to forcibly disable the service,
even if the server hosting the service is unavailable.
