Transaction processing options
Transaction processing options control how transactions are processed between the IBM Spectrum Protect client and server.
Table 1 lists the transaction processing options that are available.
Option | Description |
---|---|
collocatebyfilespec | Specifies that you want the backup-archive client to use only one server session to send objects generated from one file specification. Setting the collocatebyfilespec option to yes eliminates interspersing of files from different file specifications, by limiting the client to one server session per file specification. Therefore, if you store the data to tape, files for each file specification are stored together on one tape (unless another tape is required for more capacity). |
commrestartduration | Specifies the maximum number of minutes you want the client to try to reconnect to the IBM Spectrum Protect server after a communication error occurs. |
commrestartinterval | Specifies the number of seconds you want the client to wait between attempts to reconnect to the IBM Spectrum Protect server after a communication error occurs. |
diskbuffsize | Specifies the maximum disk I/O buffer size (in kilobytes) that the client can use when reading files. |
largecommbuffers | This option has been replaced by the diskbuffsize
option. At this time, largecommbuffers is still accepted by the backup-archive
client in order to ease the transition to the new option. However, the value specified by
largecommbuffers is ignored in favor of the diskbuffsize setting.
Important: Discontinue the use of largecommbuffers because future
releases of the client might not accept this option.
|
nfstimeout | Specifies the number of seconds the server waits for a status system call on an NFS file system before it times out. |
resourceutilization | Use the resourceutilization option in your client options file dsm.opt to regulate the level of resources the IBM Spectrum Protect server and client can use during processing. |
resourceutilization | Use the resourceutilization option in your dsm.sys file to regulate the level of resources the IBM Spectrum Protect server and client can use during processing. |
txnbytelimit | Specifies the number of kilobytes the client program buffers before it sends a transaction to the server. |
usedirectory | Provides a convenient way to simplify client communication configuration by overriding commmethod parameters set in the client options file and instead querying the Active Directory for the communication method and server with which to connect. |
