Readme file for:
IBM Spectrum Symphony
Product/Component Release: 7.2.1.1
Fix ID:
sym-7.2.1-build601362-ms
Publication date: December
9, 2022
Fix to update the IBM Spectrum Symphony host
factory symA requestor
plug-in to limit requests by the IBM Spectrum Symphony session manager's slot
demand, instead of by the number of active tasks. This allows symA to scale workload with
service to slot ratios that are not one to one. This fix also introduces the batch_return_mode
configuration in symA to improve
the performance for closing and removing hosts in host factory.

EGO,
Linux x86_64, sym-7.2.1-build601362-ms
Follow these instructions to
download and install this interim fix on the management hosts in your cluster.
System requirements
Linux
x86_64
Installation
a. Log on to the primary host as the
cluster administrator:
> egosh user logon -u Admin -x
Admin
b.
Source the host environment:
(bash) >
source $EGO_TOP/profile.platform
(csh) >
source $EGO_TOP/cshrc.platform
c. Stop all services:
> egosh service stop all
d. On each management host, stop EGO:
> egosh ego shutdown
e.
On each management host, create a directory (for example, /symfixes) and download the egocore-3.7.0_x86_64_build601362.tar.gz package to the directory.
f. Use the egoinstallfixes command to install the egocore-3.7.0_x86_64_build601362.tar.gz package:
> egoinstallfixes /symfixes/egocore-3.7.0_x86_64_build601362.tar.gz
--silent
Important:
Running the egoinstallfixes command automatically backs
up the current binary files to a fix backup directory. For recovery
purposes of the original file, do not delete this backup directory. For
more information on using this command, see the egoinstallfixes command
reference.
g.
Use
the pversions command to verify the installation:
> pversions
-b 601362
h.
On each
management host, start EGO, starting at the primary:
> egosh
ego start
Configuration
1.
Create a
backup copy of the symAreq_config.json file located in the $EGO_CONFDIR/../../eservice/hostfactory/conf/requestors/symA/conf directory.
2. To
enable the batch return feature, set "batch_return_mode" to true in symAreq_config.json. For
example:
"batch_return_mode":
true,
In this example, symA will use the egosh resource close
-b
command option to pass the list of hosts to VEMKD in one request. Without the -b option, egosh resource close will make
one request for each host. The default for this configuration is false for this
fix.
If required, follow these instructions to uninstall this interim fix on Linux management hosts in your cluster.
a. Log on to the primary host as the
cluster administrator:
> egosh user logon -u Admin -x Admin

Source the host environment:
(bash) >
. $EGO_TOP/profile.platform
(csh) >
source $EGO_TOP/cshrc.platform
c. Stop all services:
> egosh service stop all
d. On each management host, stop EGO:
> egosh ego shutdown
e. Log on to
each management host and roll back this interim fix:
> egoinstallfixes -r 601362
f.
Restore the backed up copy of the symAreq_config.json configuration file.
