Searching the Help
To search for information in the Help, type a word or phrase in the Search box. When you enter a group of words, OR is inferred. You can use Boolean operators to refine your search.
Results returned are case insensitive. However, results ranking takes case into account and assigns higher scores to case matches. Therefore, a search for "cats" followed by a search for "Cats" would return the same number of Help topics, but the order in which the topics are listed would be different.
Words and Phrases
| Search for | Example | Results |
|---|---|---|
| A single word | cat
|
Topics that contain the word "cat". You will also find its grammatical variations, such as "cats". |
|
A phrase. You can specify that the search results contain a specific phrase. |
"cat food" (quotation marks) |
Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase. |
Using Boolean Operators
| Search for | Operator | Example |
|---|---|---|
|
Two or more words in the same topic |
|
|
| Either word in a topic |
|
|
| Topics that do not contain a specific word or phrase |
|
|
| Topics that contain one string and do not contain another | ^ (caret) |
cat ^ mouse
|
| A combination of search types | ( ) parentheses |

Configure High Availability Mode
The typical configuration for a high availability environment has two or more UCMDB Browsers that connect to the same UCMDB server, or to the same load balancer that manages a cluster of UCMDB servers. The UCMDB Browsers are configured to work behind a load balancer, meaning that the load balancer serves as the entry point to the UCMDB Browsers. All the UCMDB Browsers are active at any given time and can handle requests from users. Requests are distributed to the UCMDB Browsers in the cluster by the load balancer, and are shared evenly among all the UCMDB Browsers.
Note
- The load balancer used for high availability must have the ability to insert cookies and must be able to perform health checks ("keepalive").
-
These instructions are certified for the F5 BIG-IP version 10.x and F5 BIG-IP version 11.x load balancers.
If you are using a different load balancer, the configuration should be performed by a network administrator who has broad knowledge about how to configure load balancers, and principles similar to those described here should be applied.
- This procedure assumes that you already have at least one UCMDB Browser installed and configured.
To set up a high availability environment:
-
Create a cluster of UCMDB Browsers.
Install one or more additional UCMDB Browsers to create a cluster. For information about installing the UCMDB Browser, see Installation.
Note
- The machines used for all of the UCMDB Browsers in the cluster should have similar hardware, including the same amount of memory, and should be running the same operating system.
- UCMDB Browsers in the cluster must use the same port number for HTTP, HTTPS, and so on. You cannot configure multiple UCMDB Browsers for high availability if they are using different ports.
-
Start the UCMDB Browsers.
-
If the first UCMDB Browser is not started, start the process and wait for the startup process to complete.
- Start the additional UCMDB Browsers.
-
-
Configure the load balancer.
The load balancer is used to balance the load that is sent to the UCMDB Browsers in the cluster. Configure the load balancer as follows:
- On the load balancer, configure a Cluster VIP address that sends requests to the entire UCMDB Browser cluster.
- Configure a pool of back-end servers that represents all UCMDB Browsers in the cluster. This pool is monitored by a health monitor, which sends requests that can be processed by any UCMDB Browser in the cluster.
-
Configure the health monitor by providing a keepalive address. The health monitor checks for the keepalive page of each of the UCMDB Browsers. For the Cluster VIP address, use the following URL for the keepalive address: /ucmdb-browser/public/ping.jsp.
Possible responses from this URL are:
Response HTTP Response Code Up 200 OK (desired response) Down 503 Service unavailable - Connect the health monitor to the UCMDB Browser pool configured in step b.
-
Configure session affinity on the load balancer:
- Configure the load balancer to insert cookies to the responses that are sent back to UCMDB Browser clients (internet browsers).
-
Using the Insert method, add a persistence profile cookie for the VIP address.
Note
- The cookie name and value are unimportant, as long as the load balancer knows how to maintain stickiness with the cookies that it sends out.
- F5 BIG-IP version 10.x adds a session cookie only to the first response per connection to the server. Other load balancers you might use add a session cookie to each response.
- If the VIP is configured to accept secure connections and the load balancer forwards the requests to the UCMDB Browsers over HTTP, you must configure redirect rewrites. In the load balancer software, enable the Redirect Rewrite select All option to configure the HTTP profile associated with the Cluster VIP.
