Error description
In Process Portal, user avatars, which are displayed in areas such as the task list, are not cached. This can result in a significant performance degradation in rendering a page, especially if several avatars are being displayed. With avatars typically not being updated frequently, caching of avatars in the browser can significantly enhance performance of page loading. Identifying the issue: With the following trace *=info:com.ibm.bpm.rest.*=all the following rest API call will be made multiple times per user rest/bpm/wle/v1/avatar/image/<username>?preventCache=14208089482 00 Using this trace *=info:org.springframework.jdbc.*=all:WAS.clientinfopluslogging= all you will see the following query called thousands of times. You can also get a report from the database describing the frequency of calls to the database and you will see this have a high frequency of calls. select USER_ID, USER_AVATAR_IMAGE from BPM_USR_AVATAR where USER_ID = ?
Local fix
None. Customer can still use the product, but there is a performance degradation.
Problem summary
**************************************************************** * USERS AFFECTED: Users of BPM Advanced, BPM Standard, and * * BPM Express. * **************************************************************** * PROBLEM DESCRIPTION: In Process Portal, user avatars are * * not cached, which can result in a * * significant performance degradation * * in rendering a page. * **************************************************************** * RECOMMENDATION: * **************************************************************** The "Cache-Control" attribute in the request header for an avatar was always set to "no-cache, no-store, max-age=0", effectively disabling browser caching for the avatar.
Problem conclusion
Setting the "Cache-Control" attribute to "public, max-age=604800, s-maxage=604800" in the request header for an avatar allows avatars to be cached. This implementation of avatar caching will rebuild the cache upon page refresh, but will not do so otherwise, regardless of the amount of time elapsed or the number of operations performed in a given Process Portal session. Interim fixes for Business Process Manager Version 8.0.1.1 and Version 8.0.1.2 have been published to Fix Central.
