Command Constructor
mMC command is made of the following parts:
Command name
Scanning options
Data source type
Data source configuration
Each step guides through one part of the command. Only the result command presented in the final step is sufficient for running mMC for scanning.
Step 1. Launch mMC
In the command line, set the mMC location as a working directory. From there, launch mMC by running mmc-cli:
Step 2. Set Scanning Options
Configure the scanning process and the output using scanning options.
First of all, to log into migVisor provide the username (-u/--username). Setting the username is required.
By default, mMC runs in online mode and uploads the scan results directly to mConsole. To save scan results to an encrypted ZIP file locally and run mMC in offline mode, use the -l/--local option.
The query definition files are downloaded together with mMC and stored in the mMC directory. By default, mMC uses these query definition files and updates them automatically. To use other query definition files, use the -q/--query-file option and specify path(s) to file(s).
The default maximum number of threads to use for parallel execution of queries is 4. To override it, use the -t/--threads option.
The default query timeout is 4 minutes. To override it, use the --qt/--query-timeout option.
For example, the command for saving scan results to an encrypted ZIP file locally, using the older query definition files saved locally, with a maximum of 10 parallel threads and the 30-minute query timeout, begins with:
Step 3. Define Source Type
Enter the source keyword and the source type (database or application):
If a single database is being scanned, enter its DB engine name:
db2luwhbasemongodbmysqloraclepostgresqlsqlserver
If a single application is being scanned, enter its primary language:
javacsharp
If data source configuration(s) is(are) set in configuration file(s), enter the
confkeyword.
For example, the command for scanning a single Oracle database begins with:
Or, for scanning multiple applications, the command begins with:
Step 4. Add Source(s)
To scan a single data source, specify the data source configuration using the arguments listed on migVisor Metadata Collector (mMC).
To scan data source(s) using configuration file(s), enter the configuration file location(s).
For example, for scanning a single Oracle database, execute:
Or, for scanning multiple applications, execute:
