name of the directory where the Metrocluster caeva environment file is located.

DT_APPLICATION_STARTUP_POLICY This parameter defines the preferred policy to start the

 

application with respect to the state of the data in the local

 

volumes. It must be set to one of the following two policies:

 

Availability_Preferred: The user chooses this policy

 

if he prefers application availability. Metrocluster software

 

allows the application to start if the data is consistent even

 

if the data is not current.

 

Data_Currency_Preferred: The user chooses this policy

 

if he prefers the application to start on consistent and current

 

data. Metrocluster software allows the application to operate

 

only on current data. This policy only focuses on the state

 

of the local data (with respect to the application) being

 

consistent and current.

 

A package can be forced to start on a node by creating the

 

FORCEFLAG in the package directory.

WAIT_TIME

(0 or greater than 0 [in minutes])

 

This parameter defines the timeout, in minutes, to wait for

 

completion of the data merging or copying for the DR group

 

before startup of the package on destination volume.

 

If WAIT_TIME is greater than zero, and if the state of DR

 

group is “merging in progress” or “copying in progress”,

 

Metrocluster software waits until WAIT_TIME value for the

 

merging or copying is complete. If WAIT_TIME expires and

 

merging or copying is still in progress, the package fails to

 

start with an error.

 

If WAIT_TIME is 0 (default value), and if the state of DR

 

group is “merging in progress” or “copying in progress”

 

state, Metrocluster software will not wait and will return an

 

exit 1 code to Serviceguard package manager. The package

 

fails to start with an error.

DR_GROUP_NAME

The name of the DR group used by this package. The DR

 

group name is defined when the DR group is created.

DC1_STORAGE_WORLD_WIDE_NAME The world wide name of the EVA storage system that resides in Data Center 1. This storage system name is defined when

 

the storage is initialized.

DC1_SMIS_LIST

A list of the management servers that reside in Data Center

 

1. Multiple names can be defined by using commas as

 

separators.

 

If a connection to the first management server fails, attempts

 

are made to connect to the subsequent management servers

 

in their order of specification.

DC1_HOST_LIST

A list of the clustered nodes that reside in Data Center 1.

 

Multiple names can be defined by using commas as

 

separators.

DC2_STORAGE_WORLD_WIDE_NAME The world wide name of the EVA storage system that resides in Data Center 2. This storage system name is defined when

 

the storage is initialized.

DC2_SMIS_LIST

A list of the management servers that reside in Data Center

 

2. Multiple names can be defined by using commas as

 

separators.
