4.3. Adjusting the search size and time limit


Some queries, such as requesting a list of IdM users, can return a very large number of entries. By tuning these search operations, you can improve the overall server performance when running the ipa *-find commands, such as ipa user-find, and when displaying corresponding lists in the Web UI.

Search size limit

Defines the maximum number of entries returned for a request sent to the server from a client’s CLI or from a browser accessing the IdM Web UI.

Default: 100 entries.

Search time limit

Defines the maximum time (in seconds) that the server waits for searches to run. Once the search reaches this limit, the server stops the search and returns the entries discovered in that time.

Default: 2 seconds.

If you set the values to -1, IdM will not apply any limits when searching.

重要

Setting search size or time limits too high can negatively affect server performance.

You can adjust the search size and time limits globally or for a specific entry to optimize search performance and responsiveness.

Procedure

  1. To display current search time and size limits in CLI, use the ipa config-show command:

    $ ipa config-show
    
    Search time limit: 2
    Search size limit: 100
  2. To adjust the limits globally for all queries, use the ipa config-mod command and add the --searchrecordslimit and --searchtimelimit options. For example:

    $ ipa config-mod --searchrecordslimit=500 --searchtimelimit=5
  3. To temporarily adjust the limits only for a specific query, add the --sizelimit or --timelimit options to the command. For example:

    $ ipa user-find --sizelimit=200 --timelimit=120

You can adjust global search size and time limits using the IdM Web UI to optimize search performance and responsiveness.

Procedure

  1. Log in to the IdM Web UI.
  2. Click IPA Server.
  3. On the IPA Server tab, click Configuration.
  4. Set the required values in the Search Options area.

    Default values are:

    • Search size limit: 100 entries
    • Search time limit: 2 seconds
