PQ60472: PROVIDE SOME GUIDANCE ON LDAP CONNECTION/THREAD SETTINGS | |||||||||||||||||||||||||
![]() |
|||||||||||||||||||||||||
APAR status Closed as documentation error. Error description There are two settings in the slap.conf file, maxConnections and maxThreads. These are set to 10 by the customization dialogs. The value of 10 was too small for a certain customer which caused ldap connection failures. He increased it to get around the problem, but would like some guidance in the Installation and Customization Guide on what he should use.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0.1 for z/OS and OS/390 * **************************************************************** * PROBLEM DESCRIPTION: The WebSphere for z/OS: Installation * * and Customization publication should be * * updated to provide some guidance on * * LDAP maxConnections/maxThreads. * **************************************************************** * RECOMMENDATION: * **************************************************************** The WebSphere for z/OS: Installation and Customization publication doesn't have a guideline for maxConnections and maxThreads. The WebSphere for z/OS: Installation and Customization publication should be updated to include a guideline on maxConnections and maxThreads.Problem conclusion The following publications were revised as a result of APAR PQ60472: ________________________________________________________________ NOTE: Periodically, we refresh the documentation on our Web site, so the changes might have been made before you read this text. To access the latest on-line documentation, go to the product library page at: http://www.ibm.com/software/webservers/appserv/ ________________________________________________________________ ________________________________________________________________ Document Name: WebSphere Application Server V4.0.1 for z/OS and OS/390: Installation and Customization Document Number: GA22-7834-05 ________________________________________________________________ Information on page 51 has been changed to read: There are two settings in the slap.conf file: maxConnections and maxThreads. Both are set to a default of 10 by the customization dialogs. However, this value may be too small for your system--a situation that can cause LDAP connection failures. You can determine the correct value to use based on the release and/or APAR level you are running for the LDAP server on your system. Beginning with z/OS V1R2 (or after applying APAR OW50971 to OS/390 V2R10 or z/OS V1R1), you should use the configuration parameter "commThreads" and specify to run with approximately two times the number of CPUs dedicated to the LPAR in which the LDAP server is running. "maxConnections" can be set independently and represents the maximum number of concurrently connected clients that you want the server to allow. It now has a minimum of 30 and a maximum that depends on MAXFILEPROC from BPXPRMxx. See Security Server LDAP Server Administration and Use for more information on how to configure LDAP.Temporary fix Comments
