Desktop Issues 48 Oracle Solaris 11.3 Release Notes • January 2016 SPARC Platform Type of USB Device Recommended Usage of USB Connectors Value of the ehci-port- forced-to-companion Variable in the /kernel/ drv/ehci.conf File T3-1, T4-1, T3-2, T4-2, T3-4, T4-4 Virtual keyboard or mouse None 2 To implement the workaround, perform the following steps: 1. Connect the USB devices. The recommended USB connectors for the devices on various platforms are listed in Table 4 . 2. Set the value of the ehci-port-forced-to-companion variable in the /kernel/drv/ ehci.conf file. For example, if the SPARC platform is T3–4 and you are using a physical keyboard, set ehci-port-forced-to-companion =3. For information about the value that you can set for this variable, see Table 4 . 3. Reboot the system. # init 6 Trusted Extensions Desktop Users Are Logged Out After 15 Minutes (18462288) When Trusted Extensions is enabled, users are logged out after 15 minutes of idle time. However, the default value of idletime in the user_attr (1M) database specifies to lock the screen after 30 minutes. Workaround: To restore the default behavior, add the following properties in the /etc/ security/policy.conf file: idletime=30 idlecmd=lock Note that the idlecmd setting is ignored unless idletime is also specified. These properties can also be customized for individual users by using the usermod command. For more information, see the usermod (1M) man page.
Performance Issues Chapter 4 • Runtime Issues 49 Plugin Container Crashes Frequently After an Upgrade to Firefox 31.1.1 ESR (20788558) After upgrading Firefox to version 31.1. x , the plugin container leaves core whenever plugins are made active. No error message is displayed, but the plugin-container binary crashes. Workaround: Disable all the plugins by performing the following steps: 1. Choose Add-ons from the Tools menu. 2. Click the Plugins tab. 3. Select the Never Activate option from the drop-down list for each plugin. Performance Issues This section describes the performance issues in the Oracle Solaris 11.3 release. Runnable Thread Occasionally Stays in Run Queue for a Longer Period (17697871) Sometime transient threads stay longer on the CPU. Currently, the kernel has no mechanism to detect long-running transient threads. When this condition occurs, a single runnable thread on a CPU's run queue can starve, leading to various issues such as a drop in performance and node eviction. Workaround: Disable transient threads by setting the following attributes in the /etc/system file: thread_transience_kernel=0 thread_transience_user=0 SPARC: Multiple Memory DR Operations Might Trigger Limited Calls to the defdump_init() Function (19651809) Because each memory dynamic reconfiguration (DR) operation might trigger multiple deferred dump reinitializations, DR operations might be slow.
