You can perform maintenance on a database, like reindexing,
without stopping AS4 Microservice.
About this task
This task disconnects the data grid of an installation of AS4 Microservice
from the database. Both the data grid and database store the same
configuration information for AS4 Microservice. When the database
is disconnected from the data grid, AS4 Microservice can save configuration
information to the data grid but that information is not written to
the database.
Enter all commands from the install_dir\Members\bin directory of the installation
of AS4 Microservice>.
Procedure
- Enter the following command to see if the container member
is running on the node where you are performing maintenance on the

If the container member is not running, enter one of the following
commands to start the member:
- (Linux® and Windows)
execute member start container
- (Windows only)

from the database:
execute maint_mode enable <domainName>

- Enter the following command to reconnect the data grid
to the database:
execute maint_mode disable <domainName>
Use the
domainName parameter to specify the domain that includes two or more data
grids.
The operation of AS4 Microservice with both the data grid and the database resumes. If any information
was changed in the data grid while the database was being maintained,
the changes are written to the database within 1 minute after the
database is reconnected.
