kernel for exchange server recovery

After the Exchange project has been planned, deployed, and tested into the operations dimension, the administrator needs to master day-to-day maintenance, monitoring, and queue tracking basic management. In simple terms, the purpose of maintenance is to ensure the normal operation of the mail system and the timely recovery of data failure; The purpose of monitoring is to cut down the normal functioning of s

log files in the Exchange Server database system? We look at the following aspects: 1. As an enterprise-class mail database system, data security and integrity must be foolproof. Must be able to face any possible crashes and outages at any time, what happens if we crash? To be able to reduce the loss of data to the latest level. 2. High-performance message throughput must be provided, and transaction opera

mount the RDBVIP in the EMC console.4. After mounting the recovery database, run restore-mailbox–identity user1–recoverydatabase rdpuserdb01 in the Exchange server's EMS. The purpose of this command is to merge the User1 mailbox content in the recovery database with the current User1 mailbox.If you are merging messages from all users, use the command:Get-mailbox

Tags: Exchange Server 201 lagged Database copy SafetyNet1) Why to use a lagged database copyTo avoid database logical corruption and storage logic corruption.Typically, a lagged database copy is generally not required because the organization has multiple non-lagged copies of the mailbox database, combined with the application of single recovery and retention pol

In this case, it is necessary to adjust the TCP kernel parameters under Linux, so that the system can release the TIME_WAIT connection faster.Open configuration file with vim: #vim/etc/sysctl.confIn this file, add the following lines of content:Net.ipv4.tcp_syncookies = 1Net.ipv4.tcp_tw_reuse = 1Net.ipv4.tcp_tw_recycle = 1Net.ipv4.tcp_fin_timeout = 30Enter the following command for the
