在使用配置了 DSA 的 Data Mover 时，请使用 dsa_configsys 工具配置源 Teradata 系统和目标 Teradata 系统。如果在该配置中提供了 -h 和 -u 选项，则 dsa_configsys 会在源系统和目标系统上重新启动 DSMAIN。如果未提供 -h 和 -u 选项，则必须在使用 DSA 之前，使用 cnsterm 手动重新启动 DSMAIN。
配置源系统和目标系统时必须考虑以下情况：
- DSC 主机必须解析为在源系统和目标系统上每个 TPA 节点都可以访问的 IP。
- 每个 TPA 节点必须解析同一系统上所有节点的 COP 条目。
- 使用 -u 选项指定的用户必须是“root”或拥有 sudo 访问权限的用户，才能运行 Teradata cnsterm 实用程序。
- 必须使用 -t 选项指定 TDPID。
build_dsainputs 和 dsa_configsys 脚本位于 /opt/teradata/datamover/support 目录下。
- 从 DSC 主机运行 hostname -i 以验证是否可以从 TPA 节点访问解析的 IP。
- 在以下服务器之一上运行 build_dsainputs，具体取决于使用的 DSA 配置：
DSA 配置 服务器 捆绑 DSA Data Mover 服务器 外部 DSA 外部 DSC 服务器 将 build_dsainputs 脚本复制到外部 DSC 服务器并从那里运行。该脚本可以复制到任何目录并从任何目录运行。
- 配置源系统和目标系统，然后使用 dsa_configsys 重新启动 DSMAIN。以下示例使用 dsa_configsys 来配置 TDPID sdt05126 并重新启动 DSMAIN：
# ./dsa_configsys -t sdt05126 -p dbc -h sdt05126 -u root {"validationlist":null,"status":"CONFIG_TERADATA_SYSTEM_SUCCESSFUL","systemName":"sdt05126","tdpId":"sdt05126","valid":true,"links":[]} sdt05126 successfully configured. --------------------------------------------------------------------------------- Preparing to stop/start DSMain. There may be a delay of 30 seconds or more after each operation. PLEASE ALLOW BOTH OPERATIONS TO COMPLETE.

Verifying that sdt05126 has registered with ActiveMQ .. please wait. sdt05126 has been successfully configured and has registered with ActiveMQ.要检查系统是否已配置 DSA，请使用 -t 以及 -p 选项和 --verify 选项。以下示例显示了在未提供任何参数时显示的 dsa_configsys 用法信息：--------------------------------------------------------------------------------- dsa_configsys Usage: dsa_configsys -t <TDPID> [-U <db_user>] -p <db_user password> [--verify] [ -h <host> -u <linux userid> [-i <identity_file>] ] | -? Description: This script will configure a TD system for DSA (similar to the 'dsc config_systems' command). After the TD system is configured DSMain must be re-started on the system. This script will restart DSMain if the -h option is specified. Run this script locally on the DSC server for which the TD systems are being configured. -t The TDPID of the system to configure. The TDPID must exactly match the definition from the Data Mover <source_tdpid> and <target_tdpid> job XML. For example: if the <source_tdpid> in the job XML is prodsys.labs.td.com then it must be specified as prodsys.labs.td.com for this option. -U (Optional) Use this option to specify a user other than 'dbc'. This user must have adequate permission for DB 'sysbar' to replace a macro (TD version < 16.00) or insert a row in table sysbar.dsaconnectionstbl (TD version >= 16.00). -p Password for user 'dbc' on the system specified above with the -t option. Optionally, the -U option can be added to specify a different user. Password must be enclosed by single quotes. --verify (Optional) Use this option along with -t and -p to check whether a system has been configured in DSA. If the system is configured then no additional configuration is needed with dsa_configsys. -h (Optional) If the user specifies the -h option followed by the TD system host (SMP) or one of the TD system hosts (MPP) then dsa_configsys will ssh into that host to restart DSMain (stop/start). -u Required when using the -h option, specify a user that has sudo permissions to run TD cnsterm commands on the host (e.g. root, ec2-user, azureuser). -i (Optional) Specify an identity file that includes the private key. Examples: ./dsa_configsys -t devsys -p dbc -h devsys -u root Configure SMP system 'devsys' and restart DSMain. ./dsa_configsys -t prodsys.labs.td.com -p dbc -h prodsys1 -i my_identityfile -u ec2-user Configure MPP system 'prodsys' and restart DSMain. Note that 'prodsys1' resolves to the first node of the MPP system. ./dsa_configsys -t prodsys -p dbc --verify Check if 'prodsys' has been configured in DSA. -? Displays usage help.
