Method Detail

addPinnedGraph

PgxFuture<java.lang.Void> addPinnedGraph(GraphConfig cfg)

Add a pinned graph (will not be unloaded by engine) to be shared between sessions

Parameters:

cfg -

demotePinnedGraph

PgxFuture<java.lang.Void> demotePinnedGraph(GraphConfig cfg)

Demote pinned graph.

Parameters:

cfg - the cfg

getExtendedVersion

PgxFuture<oracle.pgx.common.VersionInfo> getExtendedVersion()

Gets an extended version.

Returns:

VersionInfo object

getPgxConfig

PgxFuture<java.util.Map<PgxConfig.Field,java.lang.Object>> getPgxConfig()

Gets the pgx config.

Returns:

current PGX server configuration as JSON string

getPgxConfigObject

default PgxFuture<PgxConfig> getPgxConfigObject()

Gets the pgx config as PgxConfig object

Returns:

current PGX server configuration

getServerState

PgxFuture<org.codehaus.jackson.JsonNode> getServerState()

Gets the server state.

Returns:

server inspection information

Since:

2.7.0

getVersion

PgxFuture<java.lang.String> getVersion()

isRunning

PgxFuture<java.lang.Boolean> isRunning()

Check if the engine is currently up

Returns:

true if engine is currently running, false otherwise

killSession

PgxFuture<java.lang.Void> killSession(java.lang.String sessionId)

Kill session.

Parameters:

sessionId - the session to be killed

resizePool

PgxFuture<java.lang.Void> resizePool(PoolType poolType,
                                     int parallelism)

resize a pool to use a different degree of parallelism

Parameters:

poolType - which pool to resize

parallelism - the target parallelism

shutdown

PgxFuture<java.lang.Boolean> shutdown(long timeout,
                                      java.util.concurrent.TimeUnit unit)

gracefully shuts down the engine and cleans up resources. All currently enqueued tasks will be worked off prior shut down, new incoming requests get rejected. This call blocks until shut down is complete or timed out.

Returns:

true if gracefully shut down. false if timed out before shut down.

shutdownNow

PgxFuture<java.lang.Void> shutdownNow()

forces the engine to stop and clean up resources. Currently running tasks are interrupted. New incoming requests get rejected.

Throws an exception when current tasks didn't finish after a short grace period.

shutdownNowIfRunning

PgxFuture<java.lang.Void> shutdownNowIfRunning()
