Part 1 Servers Hosts and Processes
First is the Table adm_Group which contains information about BizTalk Groups. They contain information like cache frequency, the large message ,threshold bytes and certificate thumb print. This is in a way the logical top table.
Second is the adm_Host table. This table contain information about the hosts like Inproc or isolated . The thread pool size, message delivery and certificate thumbprint if configured for signing messages . Maximum delay .
This table is connected to the adm_HostInstance table .This table has info about the
host instance ( BTS Service ) running within the hosts. You can also see under what accounts the host Processes are configured to run under here . Each host has several sub services specified in the adm_HostIntance_SubServices. These are services like Caching , EPM , XLANG engine
The host are configured on th server and this enlistment is captured in the the adm_Server2HostMapping . This essentially connects the adm_hostinstance and the adm_Server .The adm_Server contains the list of servers that are members of that Biztalk group
A brief note on adm_ServiceClass is needed here as this table controls the value of the high and
low watermarks for memory , file . This setting should not be manually edited , There is a a tool
for editing these value and should have a pretty strong reason to edit these .
The adm_MessageBox table contains the messagebox entries associated with this host . You can scale biztalk by increasing the message box first vertically and then horizontally even in those situations it is recommended to go from 1 to 3 and not to 2 to see increase in performance.
Part 2 : Adapters , Recieve Ports , Send handlers ,pipelines
The next main table is the adm_Adapter , This table contains all the adapters installed for Biztalk like FTP, HTTP, EDI, File,MQ Series, MSMQ,SOAP, SQL, POP3, SMTP and WSS.
The adm_RecieveHandler table contains key to the process identification guid in the registry/DB .The adm_SendHandler is the same for the Send Process.
When we create a Recive port and a Recieve Location . The adm_ReceiveLocation will contain the entry for the port location and will have tha adapterId value corresponding to the transport type in the adm_adapter table. This will also have an entry into the bts_recieveport table which has the containing port information . similary bts_sendport contains the send port information .
In general bts_ prefix stands for the corresponding biztalk artifacts ;bts_assembly contains the deployed assemblies the bts_orchestration contains the orchestrations other tables like bts_orchestration_port,bts_pipeline follow similar pattern
In general the prefix gives you some idea about the table
- ADM_ are administration tables
- BAM_ ,BAS_ BAM or BAS specific tables
- TDDS_ Tracking tables
- BTS_ Biztalk artifacts tables
- BT_ App specific tables
- BIZTALK General tables
Hope that was informative .
