HP OpenView Storage Mirroring User Guide (360226-002, May 2004)

14 - 27
Te m p D i r Temporary directory used when replicating Windows 200x encrypted files.
GUI Setting: None
TGCloseDelay The length of time, in milliseconds, a file is held open on the target
Values: 0 - 2000
Default: 1000
GUI Setting
: None
If disk caching on the target is disabled either manually or by default (for example, by default on
disks that host Active Directory database files), the target system may be slow during a mirror. If
so, descreasing this setting to 100, 10, and 0 will result in incremental improvements, with 0
returning the system performance to normal.
TGDisableAttribute
Replication
Specifies whether or not the attributes compression, ACL, and file mask are written to the
target during mirroring and replication
Values: (0) Enable attribute replication
(
1) Disable attribute replication
Default: 0
GUI Setting: None
TGExecutionRetry
Limit
The number of times an unfinished operation will be retried on the target before it is discarded. If
this value is set to zero (
0), an operation will never be discarded and will be retried on the target
until it is applied.
Values: 0 - 65536
Default: 0
GUI Setting
: None
TGFileAlloc Indicates that Storage Mirroring allocates an entire file on the first write of a mirror operation
Values: (0) Disabled
(
1) Enabled
Default: 1
GUI Setting
: None
To help eliminate file fragmentation on the target server, Storage Mirroring should allocate the
entire file first. With extremely large files, the file allocation may take a long time. Therefore, you
may want to disable the file allocation. If you disable file allocation, you will have more
fragmentation on the target disk.
TGMirrorCapacity
High
Maximum percentage of system memory that can contain mirror data before the target signals
the source to pause the sending of mirror operations.
Values: 2-75
Default: 20
GUI Setting: Server Properties, Target tab, Files, Target Mirror Capacity High Percentage
TGMirrorCapacity
Low
Minimum percentage of system memory that can contain mirror data before the target signals the
source to resume the sending of mirror operations.
Values: 1-75
Default: 15
GUI Setting: Server Properties, Target tab, Files, Target Mirror Capacity Low Percentage
The maximum value forTGMirrorCapacityLow is either 75 or TGMirrorCapacityHigh, which ever
is lower.
TGRetryLocked Minimum number of seconds to wait before retrying a failed operation on a target
Values: 0-65536
Default: 3
GUI Setting
: Server Properties, Target tab, Queues, Retry Delay for Incomplete Operations
