4.2.6 Advanced Access Configuration

You can customize the following fields inside the pgx_realm block in the pgx.conf file to customize login behavior.

Table 4-2 Advanced Access Configuration Options

Field Name	Explanation	Default
token_expiration_seconds	After how many seconds the generated bearer token will expire.	3600 (1 hour)
connect_timeout_milliseconds	After how many milliseconds an connection attempt to the specified JDBC URL will time out, resulting in the login attempt being rejected.	10000
max_pool_size	Maximum number of JDBC connections allowed per user. If the number is reached, attempts to read from the database will fail for the current user.	64
max_num_users	Maximum number of active, signed in users to allow. If this number is reached, the graph server will reject login attempts.	512
max_num_token_refresh	Maximum amount of times a token can be automatically refreshed before requiring a login again.	24

To configure the refresh time on the client side before token expiration, use the following API to login:

int refreshTimeBeforeTokenExpiry = 900; // in seconds, default is 1800 (30 minutes)
ServerInstance instance = GraphServer.getInstance("https://localhost:7007", "<database user>", "<database password>",
    refreshTimeBeforeTokenExpiry);

Note:

The preceding options work only if the realm implementation is configured to be oracle.pg.identity.DatabaseRealm.
