Sizing for new product installations and existing BMC Server Automation installations

If you are currently using BMC Server Automation and installing BMC Decision Support for Server Automation for the first time, use the instructions in this topic to determine the size requirements for your reports data warehouse and archived data. 

A script gathers the data needed to determine your database size and archival data size requirements from the BMC Server Automation database for your primary site. After you run the script, the HTML output shows the size requirements.

Before you begin

Download the required files, as described in Sizing-tools.

To determine your reports data warehouse and archival data size requirements

  1. Log on to the BMC Server Automation database server as the BMC Server Automation database user.

  2. Run the the appropriate script for your database type:

    • Oracle:

      sqlplus <user>/<password>@<TNS_ENTRY> @bds_dbsizing_for_new_bds_oracle.sql bds_dbsizing_for_new_bds_oracle.html
      • <user> and <password> are the BMC Server Automation database user name and password.
      • <TNS_ENTRY> is the database TNS entry name.

    • Microsoft SQL Server:

      sqlcmd -S <server>\<instance> -d <BMCServerAutomationDatabaseName> -U <user> -P <password> -i bds_dbsizing_for_new_bds_sqlserver.sql -o bds_dbsizing_for_new_bds_sqlserver.html -h-1
      • <server> is the BMC Server Automation database server name.
      • <instance> is the name of the database instance.
      • <user> and <password> are the database user name and password. 

    The script generates a file named bds_dbsizing_for_new_bds_oracle.html (for Oracle) or bds_dbsizing_for_new_bds_sqlserver.html (for SQL Server) in the directory in which you executed the script.

The Oracle HTML output file provides the following information:

  • Number of BMC Server Automation sites considered for calculation
  • Number of managed servers in the existing environment
  • Number of days for which data was available for calculation
  • Number of days in the past for which server growth is considered for projecting the requirements in the next six months and one year
  • Recommended initial disk space (in GB) required by each tablespace in the reports data warehouse
  • Projected disk space (in GB) required by each tablespace in next six months and one year
  • Recommended initial disk space (in GB) required for the archived data considering a retention period of 3 months

The SQL Server HTML output file provides the following information:

  • Number of managed servers in the existing environment
  • Number of days for which data was available for calculation
  • Number of days in the past for which server growth is considered for projecting the requirements in the next six months and one year
  • Recommended initial disk space (in GB) required by the data file and log file in the reports data warehouse
  • Projected disk space (in GB) required by the data file and log file in next six months and one year
  • Recommended initial disk space (in GB) required for the archived data considering a retention period of 3 months

If you need to increase the database size, use the instructions provided by your database vendor.

Note

  • This sizing process calculates the size requirements based on one BMC Server Automation site. If you are using more sites, the size requirements increase proportionally.
  • Retention period indicates the period of time for which data is retained. Data that is older than the retention period is archived.
