Please let me know what could this option (-wrl) stand for in relation to this Oracle wallet creation. This would help me to have a mental map what wrl means.
Sample command: mkstore -wrl <wallet_location> -createCredential wallet-alias scott tiger
Based on the v$encryption_wallet view column names and descriptions, it's probably fair to assume it stands for "wallet resource locator".
The glossary seems to back that up:
Wallet Resource Locator
A wallet resource locator (WRL) provides all necessary information to locate a wallet. It is a path to an operating system directory that contains a wallet.
