Does Windows Server AppFabric Cache compression cause data to be stored compressed or just transmitted compressed?
Is it intended to just save network bandwidth or both bandwidth and server memory ?
Note this is a Windows Server AppFabric question.
Yes, because data is compressed on the client.
A really simple way to check this is to CmdLet Get-CacheStatistics.
DataCacheServerEndpoint[] servers = new DataCacheServerEndpoint[1];
servers[0] = new DataCacheServerEndpoint("fr-vmrd-web1", 22233);
DataCacheFactoryConfiguration factoryConfig = new DataCacheFactoryConfiguration();
factoryConfig.Servers = servers;
factoryConfig.SecurityProperties = new DataCacheSecurity(DataCacheSecurityMode.None, DataCacheProtectionLevel.None);
factoryConfig.TransportProperties.MaxBufferSize = int.MaxValue;
factoryConfig.TransportProperties.MaxBufferPoolSize = int.MaxValue;
factoryConfig.IsCompressionEnabled = true;//or false
DataCacheFactory mycacheFactory = new DataCacheFactory(factoryConfig);
var data = File.ReadAllText(#"c:\test.log"); //40 MB
DataCache myDefaultCache = mycacheFactory.GetDefaultCache();
myDefaultCache.Put("test", data);
With Compression
...
Size : 2575360
ItemCount : 1
RegionCount : 1
...
Without Compression
...
Size : 41900032
ItemCount : 1
RegionCount : 1

Hope this will help you.

It seems to be relatively a simple question. I have two mount points on bacula-sd (storage) server- one for local drive and one for s3 bucket (off side backup) and what I need is start two concurrent job at the same time on both drives. So far I have something like that in bacula devices.conf
Device {
Name = "example.prod.com"
Device Type = File
Media Type = File
Archive Device = "/data/bacula/example.prod.com"
LabelMedia = yes
Random Access = yes
AutomaticMount = yes
RemovableMedia = no
AlwaysOpen = no
Maximum Network Buffer Size = 65536
}
Device {
Name = example.prod.com-s3
Device Type = File
Media Type = File
Archive Device = "/mnt/bacula-backup-storage/example.prod.com-s3"
LabelMedia = yes
Random Access = Yes
AutomaticMount = yes
RemovableMedia = no
AlwaysOpen = no
Maximum Network Buffer Size = 65536
}
but it's probably not enough because the job started only on the first device. Do I need disk autochanger or something?
You have to change Media Type = ... parameter to be different for both Devices, i.e.
Device {
Name = "example.prod.com"
Device Type = File
Media Type = File
...
}
Device {
Name = example.prod.com-s3
Device Type = File
Media Type = S3
...
}
It won't work otherwise.
I've been trying to set the TTL for Redis Key from within Drupal, but it does not seem be working. Our settings.php is as follows:
// Set Redis as the default backend for any cache bin not otherwise specified.
$settings['cache']['default'] = 'cache.backend.redis';
$settings['redis.connection']['interface'] = 'PhpRedis';
$settings['redis.connection']['host'] = '127.0.0.1';
$settings['redis.connection']['port'] = '6379';
$settings['redis.connection']['base'] = 8; // This is the DB ID.
#$conf['cache_lifetime_redis'] = 21600;
#$settings['redis.settings']['perm_ttl_cache_field'] = "3 months";
$conf['redis_perm_ttl'] = "3 months";
I've tried with $conf['cache_lifetime_redis'] = 21600;, with $settings['redis.settings']['perm_ttl_cache_field'] = "3 months"; and $conf['redis_perm_ttl'] = "3 months"; to no avail. When connecting to REDIS, the TTL is still set to 1 year. What else needs to be done to make this work ? settings this at the server level is a no-go, due to being a shared environment.
Default Limits: File size limit set to 26214400 bytes.
If i scan file size > 25mb, it will occur error.
The maximum stream size of 26214400 bytes has been exceeded.
I try change:
public ClamClient(string server, int port)
{
MaxChunkSize = 131072; //128k
MaxStreamSize = 209715200; //200mb ,- 26214400; //25mb
Server = server;
Port = port;
}
But it occur error when scan file:
Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host.
How change limit file size of Clamd service in Window?
Thanks all.
You need to change nclam config ("clamd.conf"):
StreamMaxLength 50M
You also have to change the ClamClient instance with a higher MaxStreamSize:
var client = new ClamClient("localhost", 3310)
{
MaxStreamSize = 52428800
};
I am attempting to replicate a SQL CE 3.5 SP1 database but upon syncrhonization, I am thrown the following error:
"Failure to connect to SQL Server with provided connection information. SQL Server does not exist, access is denied because the IIS user is not a valid user on the computer running SQL Server, or the password is incorrect."
I am using the Windows Mobile 6 Professional emulator and the machine I am attempting to connect to is a Windows Virtual Machine running Windows XP Professional SP3. I have configured the network adapter settings for the emulator (I can access web pages), verified user permissions, double checked IIS settings, and triple checked my connection string:
SqlCeReplication rpl = null;
try
{
// Creates the replication object.
rpl = new SqlCeReplication();
// Establishes the connection string.
rpl.SubscriberConnectionString = #"Data Source = \Program Files\ParkSurvey\ParkSurvey.sdf; Password = *; Temp File Max Size = 512;
Max Database Size = 512; Max Buffer Size = 512; Flush Interval = 20; Autoshrink Threshold = 10; Default Lock Escalation = 100";
// Sets the Publisher properties.
rpl.PublisherSecurityMode = SecurityType.NTAuthentication;
rpl.Publisher = "PUBLISHER";
rpl.PublisherLogin = "INDICOPUBLIC\\subuser";
rpl.PublisherPassword = "*";
rpl.PublisherDatabase = "PUBLISHER";
rpl.Publication = "ParkSurveyPublication";
// Sets the internet replication properties.
rpl.InternetUrl = "http://replication/sqlce/sqlcesa35.dll";
rpl.InternetLogin = "INDICOPUBLIC\\subuser";
rpl.InternetPassword = "*";
rpl.ConnectionManager = true;
// Sets the Distributor properties.
rpl.Distributor = "PUBLISHER";
rpl.DistributorLogin = "INDICOPUBLIC\\subuser";
rpl.DistributorPassword = "psrAdmin";
rpl.DistributorSecurityMode = SecurityType.NTAuthentication;
// Sets the timeout properties.
rpl.ConnectionRetryTimeout = 120;
rpl.ConnectTimeout = 6000;
rpl.ReceiveTimeout = 6000;
rpl.SendTimeout = 6000;
// Sets the Subscriber properties.
rpl.Subscriber = "ParkSurveySubscriber";
rpl.HostName = "Mobile1";
rpl.CompressionLevel = 6;
rpl.ExchangeType = ExchangeType.BiDirectional;
// Call the replication methods.
rpl.Synchronize();
}
catch (SqlCeException sqlEx)
{
MessageBox.Show(sqlEx.Message);
}
finally
{
// Disposing the replication object
if (rpl != null)
{
rpl.Dispose();
}
}
I have also attempted to open the host machine itself in File Explorer on the mobile emulator and am prompted that "The network path was not found.". This leads me to believe it is ActiveSync issue within the emulator itself. Does anyone have any advice?
Try with IP adresse instead of hostname, and test the agent URL from IE on the device. Make sure to use the latest build of 3.5 SP2 on all components if your DB server is SQL 2012
I have written an ActiveX control which supports drag-drop of email attachments and disk files and uploads files to a web server.
I used the samples available at this link for Uploading files
Upload files with HTTPWebrequest (multipart/form-data)
I am sending data in chunks by setting the following properties
wr = (HttpWebRequest)WebRequest.Create(UploadUrl);
wr.ContentType = "multipart/form-data; boundary=" + boundary;
wr.Method = "POST";
wr.ContentLength = contentLength;
wr.AllowWriteStreamBuffering = false;
wr.Timeout = 600000;
wr.KeepAlive = false;
wr.ReadWriteTimeout = 600000;
wr.ProtocolVersion = HttpVersion.Version10;
wr.Credentials = System.Net.CredentialCache.DefaultCredentials;
wr.SendChunked = true;
wr.UserAgent = "Mozilla/3.0 (compatible; My Browser/1.0)";
rs = wr.GetRequestStream();
With the above settings I am getting an error (411) Length Required.
After reading the following article I realized, I dont need to set Content-Length property when I set SendChunked = true;
http://en.wikipedia.org/wiki/Chunked_transfer_encoding
But the Microsoft example code here doesn't do so
http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.sendchunked.aspx
After further digging I came to know that Chunked encoding is supported in HTTP version 1.1 only. So I changed the property as follows
wr.ProtocolVersion = HttpVersion.Version11;
Now I don't see that 411 error any more.
Now, can someone with better knowledge verify my understanding here and please let me know if I am doing right.
Thanks
Ravi.
They are both just mechanisms to let the receiver know when it has reached the end of the transfer. If you want to use Content-Length, it is pretty simple. Just take your encoded byte array of POST data, and use the Length property.
ASCIIEncoding encoding = new ASCIIEncoding ();
byte[] postDataByteArray = encoding.GetBytes (postData);
wr.ContentLength = postDataByteArray.Length;
