1 Introduction
This chapter contains general information, such as an overview of the manual, how the manual is organized, and how to get technical assistance.
Overview
This manual contains the information necessary for system administration of Oracle Communications LSMS. Included are an overview of the LSMS design, routine operation procedures, preventive maintenance techniques, corrective maintenance procedures, and appendixes that describe LSMS commands and notifications.
Scope and Audience
This manual is written for system administrators of the LSMS. The manual provides routine operating procedures as well as preventive and corrective procedures that aid administrators maintaining the LSMS.
-
Preventive maintenance procedures are routines implemented on a scheduled basis to help prevent system faults. These tasks are industry standard recommendations and are adaptable to any company’s maintenance plan.
-
Corrective maintenance procedures are those used in response to a system alarm or output message. These procedures are LSMS-specific and aid in the detection, isolation, and repair of faults.
The manual assumes the system administrator is familiar with the Linux operating system.
Documentation Admonishments
Admonishments are icons and text throughout this manual that alert the reader to assure personal safety, to minimize possible service interruptions, and to warn of the potential for equipment damage.

Manual Organization
The manual contains the following chapters:
- Introduction contains general information about the organization of the manual, how to get technical assistance, and a description of the LSMS document suite.
-
LSMS Overview provides a high-level overview of the LSMS hardware and software design for high availability and an overview of software components.
-
Routine Procedures explains the routine procedures that system administrators regularly perform, such as establishing remote logins, setting the system clock, and managing user accounts.
-
Preventive Maintenance explains preventive maintenance topics, such as the LSMS preventive maintenance schedule, backup procedures, routine cleaning, and monitoring the hardware and network.
-
Restarting Software Processes explains how to verify whether software processes are running and how software processes can be automatically or manually restarted.
-
Managing Server States describes how automatic switchover occurs for certain failure conditions and how to manually manage the states of the primary and secondary servers.
-
Recovering from Site Failures describes and compares various backup strategies for disaster situations in which an entire LSMS site can no longer function. This chapter describes how to prepare for disaster recovery and, for each disaster recovery strategy, describes the recovery procedures and a list of assumptions.
-
Verifying Recovery describes the processes used to verify that recovery is acceptable after recovering from site failures.
- Field Replaceable Units describes the components of an E5-APP-B card that can be replaced in the field and includes procedures for replacing each type of field replaceable unit (FRU).
-
Commands describes the purpose and syntax for all LSMS commands and provides sample output for each.
-
Automatic Monitoring of Events describes how the LSMS automatically monitors itself for certain events, including error conditions, and reports those events with graphical user interface (GUI) notifications, Surveillance notifications, and/or traps sent to a remote monitoring device. This appendix lists all events in numerical order and provides explanations and suggested recovery for each event.
-
Downloading Files from an NPAC to the LSMS contains the prerequisite information and procedure needed for downloading files from Number Portability Administration Centers (NPACs). One example for using this procedure is when all the files for an entire regional database need to be downloaded as part of recovering after a site failure.
-
Worksheets contains blank worksheets that you can copy and use in the procedures described in other chapters.
-
Query Server Maintenance Procedures contains detailed, step-by-step procedures for maintaining the Oracle Communications LSMS Query Server (LSMS Query Server).
