How can two microservices share access to a single database?

To enable shared access of two microservices to a single database, it is necessary to:

1. Configure the database to support concurrent connections from multiple clients.
2. In each microservice, set up the database connection using appropriate drivers and connection parameters.
3. Ensure proper management of transactions and data isolation to avoid conflicts and maintain integrity.
4. Use connection pooling if necessary to optimize database operations.

For example, both microservices can use the same database connection URL, and the database will handle requests in parallel. It is also important to consider security issues and access rights segregation.
