This release note describes patch SG0001912 to IRIX 6.3.
Patch SG0001912 does not replace any other patches.
1.1 _S_u_p_p_o_r_t_e_d__H_a_r_d_w_a_r_e__P_l_a_t_f_o_r_m_s
This patch contains bug fixes for all platforms.
1.2 _S_u_p_p_o_r_t_e_d__S_o_f_t_w_a_r_e__P_l_a_t_f_o_r_m_s
This patch contains bug fixes for IRIX 6.3.
1.3 _B_u_g_s__F_i_x_e_d__b_y__P_a_t_c_h__S_G_0_0_0_1_9_1_2
This patch contains fixes for the following bugs in IRIX
6.3. Bug numbers from Silicon Graphics bug tracking system
are included for reference.
+o Bug #469955 - No significant improvements were made to
libirixpmda in IRIX 6.2 and IRIX 6.3 from IRIX 5.3.
During development of IRIX 6.4 and IRIX 6.4.1, and the
ongoing development of IRIX 6.5, new metrics were added
and bugs fixed that are relevant to IRIX 6.2 and IRIX
6.3. These changes have been back ported for this patch
(#459836), including support for:
+o R10000 event counters (#434096, #434532, #435412
and #447409);
+o high precision counters (#421591, #429062,
#430236, #434096, #434557, #434563 and #455866);
+o NFS3 metrics (#422007, #422319, #422420 and
#429815);
+o additional memory and swap metrics (#447955,
#448730 and #461637); and
+o reseting libirixpmda if the host configuration has
changed (#421591).
This patch also includes several fixes to improve the
stability of libirixpmda in respect to:
+o memory metrics (#365244);
+o help text (#422007);
- 2 -
+o disk spindles (#429061);
+o hinv metrics (#434995 and #435442);
+o CPU metrics (#435852 and #437661);
+o asynchronous I/O metrics (#436300);
+o warning and error log messages (#438608); and
+o kmem readers (#467542).
1.4 _S_u_b_s_y_s_t_e_m_s__I_n_c_l_u_d_e_d__i_n__P_a_t_c_h__S_G_0_0_0_1_9_1_2
This patch release includes these subsystems:
+o patchSG0001912.eoe_sw.perf (eoe.sw.perf)
1.5 _I_n_s_t_a_l_l_a_t_i_o_n__I_n_s_t_r_u_c_t_i_o_n_s
Because you want to install only the patches for problems
you have encountered, patch software is not installed by
default. After reading the descriptions of the bugs fixed
in this patch (see Section 1.3), determine the patches that
meet your specific needs.
If, after reading Sections 1.1 and 1.2 of these release
notes, you are unsure whether your hardware and software
meet the requirements for installing a particular patch, run
_i_n_s_t. The _i_n_s_t program does not allow you to install
patches that are incompatible with your hardware or
software.
Patch software is installed like any other Silicon Graphics
software product. Follow the instructions in your _S_o_f_t_w_a_r_e
_I_n_s_t_a_l_l_a_t_i_o_n _A_d_m_i_n_i_s_t_r_a_t_o_r'_s _G_u_i_d_e to bring up the miniroot
form of the software installation tools.
Follow these steps to select a patch for installation:
1. At the Inst> prompt, type
iiiinnnnssssttttaaaallllllll ppppaaaattttcccchhhhSSSSGGGG_x_x_x_x_x_x_x
where _x_x_x_x_x_x_x is the patch number.
2. Initiate the installation sequence. Type
IIIInnnnsssstttt>>>> ggggoooo
- 3 -
3. You may find that two patches have been marked as
incompatible. (The installation tools reject an
installation request if an incompatibility is
detected.) If this occurs, you must deselect one of
the patches.
IIIInnnnsssstttt>>>> kkkkeeeeeeeepppp ppppaaaattttcccchhhhSSSSGGGG_x_x_x_x_x_x_x
where _x_x_x_x_x_x_x is the patch number.
4. After completing the installation process, exit the
_i_n_s_t program by typing
IIIInnnnsssstttt>>>> qqqquuuuiiiitttt
1.6 _P_a_t_c_h__R_e_m_o_v_a_l__I_n_s_t_r_u_c_t_i_o_n_s
To remove a patch, use the _v_e_r_s_i_o_n_s _r_e_m_o_v_e command as you
would for any other software subsystem. The removal process
reinstates the original version of software unless you have
specifically removed the patch history from your system.
vvvveeeerrrrssssiiiioooonnnnssss rrrreeeemmmmoooovvvveeee ppppaaaattttcccchhhhSSSSGGGG_x_x_x_x_x_x_x
where _x_x_x_x_x_x_x is the patch number.
To keep a patch but increase your disk space, use the
_v_e_r_s_i_o_n_s _r_e_m_o_v_e_h_i_s_t command to remove the patch history.
vvvveeeerrrrssssiiiioooonnnnssss rrrreeeemmmmoooovvvveeeehhhhiiiisssstttt ppppaaaattttcccchhhhSSSSGGGG_x_x_x_x_x_x_x
where _x_x_x_x_x_x_x is the patch number.
1.7 _K_n_o_w_n__P_r_o_b_l_e_m_s
If the Performance Co-Pilot (PCP) is installed and the
collector daemon ppppmmmmccccdddd(1) is running, ppppmmmmccccdddd((((1111)))) should be
stopped before installing the patch with the command (as
root):
#### ////eeeettttcccc////iiiinnnniiiitttt....dddd////ppppccccpppp ssssttttoooopppp
After installing the patch:
+o the PCP namespace should be rebuilt to include the new
metric names (as root):
#### ccccdddd ////vvvvaaaarrrr////ppppccccpppp////ppppmmmmnnnnssss;;;; ....////RRRReeeebbbbuuuuiiiilllldddd
- 4 -
+o ppppmmmmccccdddd(1) should be restarted (as root):
#### ////eeeettttcccc////iiiinnnniiiitttt....dddd////ppppccccpppp ssssttttaaaarrrrtttt
Failure to stop ppppmmmmccccdddd(1) before installing this patch may
result in the unexpected termination of ppppmmmmccccdddd(1). Failure to
rebuild the PCP namespace and restart ppppmmmmccccdddd(1) after
installing this patch will prevent the fixes and
enhancements of the patch from taking effect.
