Avoiding Windows service accounts with static passwords using GMSAs

This may not be possible with windows http: Grizly 1, 13 Hey Grizly -- thanks for the response! I tried both commands you suggested, but I got: Either the interface index is wrong or the gateway does not lie on the same network as the interface.

Check the IP Address Table for the machine. Just ignore the "metric 1 if 2" part.. Best to test without -p as well. Ohh, my bad, seems the gateway is the ip of the interface.. Right, which is what I am already doing, and what I was hoping to avoid. I tried this on Windows 7 x I had a problem with this, as it captured all possible IPv4 addresses and routed these to the dial-up connection: XX 11 I did not want all my traffic to pass through the VPN, so in case anybody needs it, I wrote a small cmd file to remove these routes and then install the only one I need Another way is to use arp -a and make note of the hexadecimal number, eg: Pages The Fix my IT system blog.

Forefront Threat Management Gateway , Tutorial. This is something I always used to do with the route command. Check out Static Routing We will be configuring a machines with dual nics, one called Internal We want to add a static persistent route for all traffic to the Using the route command route add Just for reference here is the add route command details from technet.

When set to off , instructs Oracle Net to try one address. When set to on , this parameter instructs Oracle Net to progress through the list of protocol addresses in a random sequence, balancing the load on the various listeners.

When set to off , instructs Oracle Net to try the addresses sequentially until one succeeds. When set to on , this parameter instructs Oracle Net to use each address in the order presented until the destination is reached. This parameter is required for reaching the destination using a specific route, that is, by specific computers. This parameter is used to enable connections to Oracle Connection Manager.

When a connect descriptor in a tnsnames. Table describes the address list options. The following example shows a tnsnames.

The Address List Options dialog box appears. Select the appropriate option. Starting with Oracle Database 12 c Release 1 Setting these parameters in the sqlnet. The following example shows how to set compression:. In addition to the service name, you can optionally configure the connect data information with the parameters described in Table Table Advanced Connect Data Settings in the tnsnames. The database instance to access. The transfer rate of data packets being sent across the network.

You can specify the session data unit SDU size to change the performance characteristics having to do with the packets sent across the network. If you want an Oracle database server to access a third-party system through Heterogeneous Services , then set this option to on. The following procedure describes how to configure advanced connect descriptor parameters using Oracle Enterprise Manager Cloud Control:. For Directory Naming, search the network service name in the Simple Search section by selecting the network service or database service from the Results list, and then clicking Edit.

The following procedure describes how to configure advanced connect descriptor parameters using Oracle Net Manager:. In the navigator pane, select Service Naming from Directory or Local menus. If you are making these changes to the Local folder, then select Save Network Configuration from the File menu. Changes to the Directory folder are saved automatically. The connection load balancing feature improves connection performance by balancing the number of active connections among multiple dispatcher s.

In an Oracle Real Application Clusters Oracle RAC environment, connection load balancing can also balance the number of active connections among multiple instances. Because the Listener Registration LREG process can register with remote listeners, a listener can always be aware of all instances and dispatchers, regardless of their location. Depending on the load information, a listener decides which instance and, if shared server is configured, which dispatcher to send the incoming client request.

In a shared server configuration, a listener selects a dispatcher in the following order:. In a dedicated server configuration, a listener selects an instance in the following order:. If a database service has multiple instances on multiple nodes, then the listener selects the least loaded instance on the least loaded node. If shared server is configured, then the least loaded dispatcher of the selected instance is chosen. An Oracle RAC environment requires that the dispatchers on each instance be cross-registered with the other listeners on the other nodes.

Figure shows an Oracle RAC shared server database with two instances, sales1 and sales2 , of the same service, sales. The instances sales1 and sales2 reside on computers sales1-server and sales2-server , respectively. Instance sales1 has one dispatcher and instance sales2 has two dispatchers. Listeners named listener run on nodes 1 and 2.

In this example, sales2-server is the least loaded node, sales2 is the least loaded instance, and dispatcher2 is the least loaded dispatcher.

The following load information is registered. The one minute load average for each instance is for sales1 and for sales2. This can happen if more processing is required on sales1-server.

The number of connections to each instance is for sales1 and for sales2. The number of dispatcher connections to each instance is for dispatcher1 , for dispatcher2 , and for dispatcher3. The number of connections to sales1 is the same as that of its only dispatcher, dispatcher1. The number of connections on sales2 is the sum of the connections on its two dispatchers, dispatcher2 and dispatcher3 Based on the environment, the following actions occur.

The numbered actions correspond to the arrows shown in Figure LREG processes for instances sales1 and sales2 register with both listeners.

The listeners are updated dynamically on the load of the instances and dispatchers. The client sends a connect request. A connect descriptor is configured to try each protocol address randomly until one succeeds:. The listener on sales1-server was randomly chosen to receive the client connect request. The listener on sales1-server compares the load of the instances sales1 and sales2.

The comparison takes into account the load on nodes sales1-server and sales2-server , respectively. Because sales2-server is less loaded than sales1-server , the listener selects sales2-server over sales1-server.

The listener compares the load on dispatchers dispatcher2 and dispatcher3. Because dispatcher2 is less loaded than dispatcher3 , the listener redirects the client connect request to dispatcher2.

Figure shows an Oracle RAC dedicated server database with two instances, sales1 and sales2 , of the same service, sales. The listeners are dynamically updated on the load of the instances.

Based on the preceding information, sales2-server is the least loaded node and sales2 is the least loaded instance. The listener on sales1-server redirects the client connect request to the listener on sales2-server. The client connects to the listener on sale2-server. The listener starts a dedicated server process, and the dedicated server process inherits the connection request from the listener.

This enables the user to continue to work using the new connection as if the original connection had never failed. TAF is a client-side feature that allows clients to reconnect to surviving databases in the event of a failure of a database instance.

Notifications are used by the server to trigger TAF callbacks on the client-side. If both methods are used to configure TAF, then the server-side service attributes supersede the client-side settings. Server-side service attributes are the preferred way to set up TAF.

Session Failover re-creates lost connections and sessions. Select Failover replays queries that were in progress. When there is a failure, callback functions are initiated on the client-side using Oracle Call Interface OCI callbacks. This works with standard OCI connections as well as connection pool and session pool connections. TAF works with the following database configurations to effectively mask a database failure:.

Oracle Call Interface Programmer's Guide for more details on callbacks, and session pools. TAF automatically restores some or all of the following elements associated with active database connections. Other elements may need to be embedded in the application code to enable TAF to recover the connection.

TAF automatically reestablishes the connection using the same connect string or an alternate connect string that you specify when configuring failover.

TAF automatically logs a user in with the same user ID as was used before the failure. If multiple users were using the connection, then TAF automatically logs them in as they attempt to process database commands. Unfortunately, TAF cannot automatically restore other session properties. These properties can be restored by invoking a callback function. If a command was completed at the time of connection failure, and it changed the state of the database, then TAF does not resend the command. If TAF reconnects in response to a command that may have changed the database, then TAF issues an error message to the application.

Open cursors used for fetching: TAF allows applications that began fetching rows from a cursor before failover to continue fetching rows after failover.

This is called select failover. It is accomplished by re-running a SELECT statement using the same snapshot, discarding those rows already fetched and retrieving those rows that were not fetched initially. TAF verifies that the discarded rows are those that were returned initially, or it returns an error message. Any active transactions are rolled back at the time of failure because TAF cannot preserve active transactions after failover. They can be initialized by making a call from the failover callback.

A different network service name for backup connections. A backup should be specified when using preconnect to pre-establish connections. The amount of time in seconds to wait between connect attempts. Set to establish connections at failover time. This option requires almost no work on the backup server until failover time. Set to pre-established connections. This provides faster failover but requires that the backup instance be able to support all connections from every supported instance.

The number of times to attempt to connect after a failover. The ability for a transaction to complete after a recoverable database error. The type of failover.

Set to fail over the session.
