Remedy Deployment 20.02 ... Preparing Performing configuration checks Reviewing and resolving preupgrade and configuration issues

BMC Atrium Core checks

This topic provides information about the checks performed by the BMC Remedy Configuration Check utility for BMC Atrium Configuration Management Database (BMC Atrium CMDB). It also describes the expected results of the checks and corrective actions to be taken if a check fails. 

Best practice

We recommend that you run all the pre-upgrade checks before you upgrade to a higher version. If you encounter any error or warning, address the issue as it may prevent a successful upgrade.
This topic includes:

 

CMDB Config Params Check

Description

This check verifies whether the following parameters are specified as per the recommended values: 

  • CMDB-Inline-Normalization
  • CMDB RPC Normalization Queue
TypePre-upgrade check
Check performed and expected result
  • If CMDB-Inline-Normalization is set to 'F' or Private-RPC-Socket is set to any value other than  390699  2 4, the check fails.
  • If the parameter values are as per the recommended values, the check is successful.
Corrective action
  • Set CMDB-Inline-Normalization to 'T'.
  • To specify the value of the CMDB RPC Normalization Queue, look up Private-RPC-Socket setting in the Normalization Engine row in the table provided at Configuring private queue threads.

CMDB - Enum Attribute Customization Check 

Note: This check is applicable only if you are upgrading from version 9.0 or lower.

Description

This check verifies whether any custom ID values were added to the selection type attributes (OSType , SystemType, ProcessorFamily). If a custom value is added to the list, it is considered as a customization.

Note: Before this check was introduced, customizations were included in the regular enum list. Now, they are included within the custom ID range. For more information on enum types, see Enum Type Open link . BMC Atrium Core has reserved a range of enum IDs from 0 to 10,000 for these selection type attributes. All new custom values must be added with ID value starting from 10,001. 

Type

Pre-upgrade check 

Check performed and expected result

If the above mentioned customization is detected, the custom values are moved to the custom ID range (10,001 onwards) during the upgrade.

The details are logged in the CMDB Server Log.
Example:
<WARN> <TID: 0000000360> <User: sa> /* Sun Jul 19 2015 23:13:19.318 */   Moving item Windows 10 from index 77 to index 10001 as _Windows 10. Similar Item added at 78.  

Corrective action

No action required.

 CMDB - Max-Num-Caches Check

DescriptionThis check verifies whether the value of Max-Num-Caches is other than 1 and whether the Development cache mode is ON.

If the parameter Max-Num-Caches:1 is enabled in the ar.cfg (or ar.conf) file and the Development cache mode is OFF, the installation of BMC Atrium Core 9.0 can fail. However, if you set the Development cache mode to ON, Max-Num-Caches:1 has no effect.

Type

Configuration check 

Check performed and expected result

If the parameter Max-Num-Caches:1 is enabled in the ar.cfg (or ar.conf) file and the Development cache mode is OFF, the check fails and displays the following error message:

Max-Num-caches set to 1. This may cause Atrium upgrade failure. Disable this parameter in ar.cfg/ar.conf file -OR- turn ON Development cache mode.

Corrective actionDisable the parameter Max-Num-Caches:1 in the Centralize Configuration, or set the Development cache mode to ON.

Check performed and expected result

This check validates the following forms and their data threshold limits:

  • UDM:JobLog — 1000

  • RE:Job_Runs — 1000

  • RE:Job_Events — 10000

  • NE:JobRun — 1000

  • DSM:Log — 500

If the number of records in any of the forms exceeds the threshold limit, the check fails and displays the name of the form.

Corrective actionManually reduce the number of records in the forms so that the number in each form is lower than the threshold limit.

Go to top

CMDB Class Overlay Check

Description

This check verifies whether any overlays are created for BMC Atrium CMDB forms.

Note: BMC Atrium CMDB does not support overlay forms.

TypePre-upgrade check, configuration check
Check performed and expected result

If overlays are created for BMC Atrium CMDB forms, the check fails and displays the details of the overlays.

Corrective actionCheck the form name from the result file displaying the name of form containing overlay. Delete the overlay from the respective form before you proceed with the upgrade.

Type

Pre-upgrade check, configuration check 

Check performed and expected result
  • If the plug-in port specified in the ar.cfg (or ar.conf) file matches the port specified in the pluginsvr_config.xml file, the check is successful.
    If the ports do not match, the check fails and displays the following error:
    Plug in port is not configured correctly, values in ar.cfg and pluginsvr_config.xml do not match
  • For all the plug-ins configured in the pluginsvr_config.xml file, the check validates whether the files specified in the <filename> and <pathelement> parameters actually exist.
    If the files do not exist, the check fails and displays the following error:
    File <filename> configured for Plug-in: <plugin name> does not exists, check pluginsvr_config.xml.
  • For all plug-ins configured in the pluginsvr_config.xml file, the check validates whether a corresponding entry is present in the ar.cfg (or ar.conf) file:
    • If a corresponding entry exists, the check validates whether the port in the pluginsvr_config.xml file matches the port in the ar.cfg (or ar.conf) file.
    • If a corresponding entry does not exist in the pluginsvr_config.xml file and the ar.cfg (or ar.conf) file, but the port numbers do not match, the check fails and displays the following error message:
      Plug in port is not configured correctly, for Plug-in: <plugin name> in Server-Plugin-Alias entry ar.cfg.
