How to Avoid Disk Contention • • 2 minutes to read • Contributors • • • In this article BizTalk Server is designed as a persistent system. For high throughput scenarios, the MessageBox and BizTalk Tracking databases can experience severe contention. This contention can be aggravated by slow disks. If the disks are slow (greater than 15ms on average for Avg. Disk sec/Read or Avg. Disk sec/Write), it may cause SQL Server to hold onto locks longer (high Lock Wait Time and high Lock Timeouts). This, in turn, can cause the MessageBox tables (Spool and Application Queues) to grow, causing database bloat and throttling. This situation ultimately results in lower overall sustainable throughput. Note For information about identifying if a server has a disk bottleneck, see (). Windows Performance Monitor is a Microsoft Management Console (MMC) snap-in that provides tools for analyzing system performance. To avoid disk contention, do the following: Steps Reference Use Raid10/0+1 disk configurations. If possible, deploy the databases on a high-speed SAN. If multiple databases are sharing the same disks, we recommend configuring them on separate dedicated disks. Buonasera, ho due pc, un portatile ed uno fisso (Fisso => XP, Portatile => Heavy metal 2000 cartoon nowhere man full. Vista) con un router WI-FI D-Link G624T. Oggi mi sono accorto che entrambi i PC hanno lo stesso indirizzo IP cosa che prima non accadeva la prima cosa che ho pensato e che mio fratello, sotto guida degli esperti di eMule, abbia combinato qualche pasticcio nelle configurazioni del router cosi ho chiesto ma lui nega. In addition, we recommend separating the MDF and LDF files for the MessageBox database onto separate disks. Consider allocating multiple files for the TEMPDB database, as this will significantly reduce disk contention and spread the load across multiple data files. Consider separating the MessageBox database onto a dedicated server that is separate from the BizTalk Tracking databases. Assign the MSDTC log file directory to a separate dedicated drive. If there is contention on the local drive due to the PageFile or MSDTC log, try moving the PageFile and/or the MSDTC log to a separate drive. Optimize the Tracking database for write operations. Optimize the MessageBox database for read and write operations. If a BizTalk host instance is saturating the CPU, consider separating sending, receiving, processing, and tracking functionality into multiple hosts. This configures the system so that the orchestration functionality runs on a separate dedicated server to improve overall system throughput. If multiple orchestrations are deployed, consider enlisting them in different dedicated orchestration hosts. This isolates the different orchestrations and prevents contention for shared resources either in the same physical address space or on the same server. Consider using Windows Performance Monitor to diagnose disk contention issues.

Cade sempre la linea e esce un messaggio: “impossibile contattare il server”. Quando sulla connessione remota Tim Default scrivo l’indrizzo IP: 192.168.2.22 e l’indirizzo server Primario: 8.8.8.8 e secondario: 8.8.4.4 la navigazione va meglio, ma questi indirizzi tengono pochissimo e cadono. Quando loro cadono, cade subito la linea. Un’altra domanda: Sulla Connessione alla rete locale (LAN) (che sul mio computer Windows XP Home Edition sta sempre con “cavo di rete scollegato”) devo scrivere indrizzi IP e DNS, Subnet Mask e Gateway predefinito?
