Answers: Q1. Do all the windows boxes (primary Control-M/Server secondary Control-M/Server, shared folder) have to be in a windows domain ? A1.They can be on different domains however they must be able to communicate between then and both CA machines must have write/read permissions to the shared drive (both CA (primary and secondary) must have permissions to create/modify files and modify the file created by the other CA process (The CA process runs as a service which means that it runs under local system account which means that the machine needs to have the permissions ). Q2. Must the windows account that starts CA (configuration agent) process be a domain account and part of the Administrator group of the windows host? A2. As mentioned in Q1 the CA (configuration agent) runs as a service so it runs as local system account, in addition when installing the primary and the secondary the user that login must be part have administrator privileges. From the V9 Install guide page 71 "To install a secondary on Windows: 1. Log in to the computer using a user ID that has Administrator permissions." Q3. Does the HA_PG_ARCHIVE_PATH (the shared folder) have be in format \\<Machine_name\<path> ? A3.The user can map the drive however it must be mapped on the primary and secondary in the same way (have the same path can't have different paths ) so it's better having it in this format. Q4. Must the shared folder be granted read+write for the same domain account that start the CA process ? A4.It must granted read+write permissions to the primary and secondary machines as it runs as a service. Q5. How does Control-M/Server replicate the PG data from one primary PG database to secondary PG database ? A5. CTM Server PG/HA is using “Streaming replication" available from PG version 9.x Q6 How does the file CONFIG.dat is synchronized in the high availability? A6. In Control-M\Server High Availability you can change the config.dat just in the active node, and any change in file CONFIG.day will be replicated to the non-active node. Any change performed directly in the CONFIG.dat of the non-active node, will be overwritten and removed by the synchronization process. Q7. How to apply a maintenance patch/fixpack for a High Availability configurationA7. please refer to Knowledge Article 000142114 Additional Information: AQ for Control-M/Server HA 9.0.00 Fix Pack 1 (High Availability & whitepaper)additional videos on High Availabilityhttps://www.youtube.com/watch?v=o4TeGi2bC94 https://www.youtube.com/watch?v=Bsyo0zV0siQ https://www.youtube.com/watch?v=hDtb-PeiF4o |
