自管理的副本集维护教程

The following tutorials provide information in maintaining existing replica sets.

更改自管理副本集节点的 Oplog 大小

Increase the size of the oplog which logs operations. In most cases, the default oplog size is sufficient.

Perform Maintenance on Self-Managed Replica Set Members

Perform maintenance on a member of a replica set while minimizing downtime.

强制自管理副本集节点成为主节点

Force a replica set member to become primary.

重新同步自管理副本集的成员

Sync the data on a member. Either perform initial sync on a new member or resync the data on an existing member that has fallen too far behind to catch up by way of normal replication.

配置副本集标签集

Assign tags to replica set members for use in targeting read and write operations to specific members.

重新配置具有不可用成员的自管理副本集

Reconfigure a replica set when a majority of replica set members are down or unreachable.

自管理链式复制

Disable or enable chained replication. Chained replication occurs when a secondary replicates from another secondary instead of the primary.

Change Hostnames in a Self-Managed Replica Set

Update the replica set configuration to reflect changes in members' hostnames.

配置自管理辅助节点的同步目标

Specify the member that a secondary member synchronizes from.

重命名自管理副本集

Rename an unsharded replica set.

Modify a Self-Managed PSA Replica Set Safely

Safely perform some reconfiguration changes on a primary-secondary-arbiter (PSA) replica set or on a replica set that is changing to a PSA architecture.

使用自我管理的 PSA 副本集缓解性能问题

Reduce cache pressure and increased write traffic for a deployment that has a three-member primary-secondary-arbiter (PSA) architecture.
