[GitHub] [shardingsphere] MercuryTan opened a new issue, #22398: shardingjdbc5.1.1 +zk does not support custom time？
MercuryTan opened a new issue, #22398:
URL: https://github.com/apache/shardingsphere/issues/22398
**question：**
zk is connected，but when I starting the project, an exception occurred
org.apache.zookeeper.KeeperException$OperationTimeoutException: KeeperErrorCode = OperationTimeout
**When I debugged, I found：**
The zk timeout has been configured
But when actually initializing,only used “server-lists” and “namespace”。Other parameters are default values
So, how to solve this problem?

@zhaojinchao95 thank u, but adjustment sessionTimeoutMilliseconds do not take effect.
When setting the parameter “**server-list**” from
```
spring.shardingsphere.mode.repository.props.server-lists=ip:2181
```
**to**
```
spring.shardingsphere.mode.repository.props.server-lists=zkServer:2181
```
and **hosts file** settings mapping
```
ip zkServer
```
Project started successfully.

You can see `ZookeeperRepository.init(final ClusterPersistRepositoryConfiguration config)`. Maybe you need to Adjust `sessionTimeoutMilliseconds` time.

You can adjustment `sessionTimeoutMilliseconds` to 6000. And try it again.

@zhaojinchao95 in `ZookeeperRepository.init(final ClusterPersistRepositoryConfiguration config)`，did use custom time，no error reported at this time. when executing the method `ZookeeperRegistryCenter.init()`，an exception occurred
**It works when my config file is the following section：**
```
spring.shardingsphere.mode.type=Cluster
spring.shardingsphere.mode.repository.type=ZooKeeper
spring.shardingsphere.mode.repository.props.namespace= xxx
spring.shardingsphere.mode.repository.props.server-lists= xxxx
spring.shardingsphere.mode.repository.props.sessionTimeoutMilliseconds=1000
spring.shardingsphere.mode.repository.props.maxRetries=5
spring.shardingsphere.mode.repository.props.retryIntervalMilliseconds=50000
spring.shardingsphere.mode.repository.props.timeToLiveSeconds=6000
spring.shardingsphere.mode.repository.props.operationTimeoutMilliseconds=60000
spring.shardingsphere.rules.readwrite-splitting.data-sources.readwrite_ds.type=Static
spring.shardingsphere.rules.readwrite-splitting.data-sources.readwrite_ds.props.write-data-source-name=write1
spring.shardingsphere.rules.readwrite-splitting.data-sources.readwrite_ds.props.read-data-source-names=read1,read2
```
But **when I want to achieve dynamic read-write separation**, the previous exception is thrown when using the following configuration file：
RegException: org.apache.zookeeper.KeeperException$OperationTimeoutException: KeeperErrorCode = OperationTimeout
```
spring.shardingsphere.mode.type=Cluster
spring.shardingsphere.mode.repository.type=ZooKeeper
spring.shardingsphere.mode.repository.props.namespace= xxx
spring.shardingsphere.mode.repository.props.server-lists= xxx
spring.shardingsphere.mode.repository.props.sessionTimeoutMilliseconds=1000
spring.shardingsphere.mode.repository.props.maxRetries=5
spring.shardingsphere.mode.repository.props.retryIntervalMilliseconds=50000
spring.shardingsphere.mode.repository.props.timeToLiveSeconds=6000
spring.shardingsphere.mode.repository.props.operationTimeoutMilliseconds=60000
spring.shardingsphere.rules.readwrite-splitting.data-sources.readwrite_ds.type=Dynamic
spring.shardingsphere.rules.readwrite-splitting.data-sources.readwrite_ds.props.auto-aware-data-source-name=dbsource_discovery
spring.shardingsphere.rules.readwrite-splitting.data-sources.readwrite_ds.props.allow-write-data-source-query=false
spring.shardingsphere.rules.database-discovery.data-sources.dbsource_discovery.data-source-names=write1,read1,read2
spring.shardingsphere.rules.database-discovery.data-sources.dbsource_discovery.discovery-heartbeat-name=replication_delay_heartbeat
spring.shardingsphere.rules.database-discovery.data-sources.dbsource_discovery.discovery-type-name=replication_delay
spring.shardingsphere.rules.database-discovery.discovery-heartbeats.replication_delay_heartbeat.props.keep-alive-cron='0/5 * * * * ?'
spring.shardingsphere.rules.database-discovery.discovery-types.replication_delay.type=SHOW_SLAVE_STATUS
spring.shardingsphere.rules.database-discovery.discovery-types.replication_delay.props.delay-milliseconds-threshold=10000
```
Is this configuration correct?
