C.1.4 Synchronization utility (TDPOSYNC) This external executable allows the DBA to resolve discrepancies between an RMAN catalog and the TSM server due to errors that can occur during RMAN file deletion. Identifying and removing backups from the TSM server that no longer exist in the Oracle catalog frees up space on the server. The tdposync utility uses the tdpo.opt file for its options. C.1.5 Multi-buffering of data transfers TDP for Oracle introduces the option to turn on multi-buffering during backups, which can significantly increase poor performance due to network constraints. If you use this option, data buffers sent from RMAN are saved in internal TDP for Oracle buffers instead of being sent directly to the TSM server across the network. TDP for Oracle then starts a new thread, which picks up these internal buffers and sends them to the server. In this way, RMAN does not need to wait for each actual data transfer to be completed via the network before reading more data. C.1.6 LAN-free data movement TDP for Oracle supports LAN-free backup operations, which shifts the movement of data from the communications network to a storage area network (SAN). Data moves over the SAN to a SAN-attached storage device via the TSM Storage Agent. Running TDP for Oracle in a LAN-free environment decreases the load on the TSM server, allowing the server to support a greater number of simultaneous connections, and avoids constraints of the network. To enable LAN-free support, you must install the following applications on the same system as TDP for Oracle: TSM Storage Agent TSM Managed System for SAN Storage Agent C.1.7 Migration and coexistence Existing backups created using older versions of TDP for Oracle are restorable using TDP for Oracle Version 2.2. TDP for Oracle relies heavily on the tdpo.opt file for accuracy in setup and maintenance. The contents of the tdpo.opt file are different to the environment variables for TDP for Oracle Version 2.1; Version 2.1 RMAN scripts for environment variables are ignored. TSM Version 3.7 and above servers are supported. 210 Backing Up Oracle using Tivoli Storage Management
C.2 Configuration and setup on UNIX This section contains client environment information and software requirements for installing TDP for Oracle on a AIX or Sun Solaris platform. C.2.1 Installing TDP for Oracle These are the main differences from the previous version of TDP: Oracle7 inclusive Enterprise Backup Utility (EBU) is no longer supported. TSM API version 3.2 is not supported, but TSM API version 4.1.2 is included on the CD. AIX 4.3.1 is not supported. SNA LU6.2 is not supported. A new utility is included as a separate package. A new installation path is provided for TDP 64-bit architecture. C.2.1.1 Operating system requirements AIX 4.3.2 AIX 4.3.3 Solaris 2.6 Solaris 7 Solaris 8 C.2.1.2 Software requirements TSM Server Version 3 (or higher) TSM API Version 4.1.2 Oracle8 Version 8.0.x or 8.1.x C.2.1.3 Communication methods TCP/IP Shared memory The installation itself is performed with smitty install_latest on AIX and with pkgadd on Solaris, respectively.
