Troubleshooting

Player cannot open a remote session

• Confirm Global Settings for CICS/MQ or IMS Connect are saved (host + channel + queue manager, or host + data store).
• Select an operation that has descriptors (Import maps, mainframe, AtomIQ, or example).
• For CICS, start the target transaction (for example AQ00) on the mainframe before Play.
• For IMS, set Play start (Entry MID / Trancode) on the operation or in My Maps.
• Only one remote session per process — Close session on HTTP 409 / busy, or wait 15 minutes for idle release.

Screens look wrong or fields misaligned

• Re-import maps and re-OPEN Player — descriptors are not hot-reloaded.
• For CICS, the symbolic copybook must match the BMS map (one map per BMS file).
• For IMS, each .mfs file must contain exactly one MID and one MOD.

Import from mainframe or AtomIQ fails

• Save Global Settings first, then Test connection. AtomIQ Test uses the stored password only.
• JZOS Test authenticates the user; catalog and member reads run as the USS process identity.
• Stay within 50 selected members (mainframe) or 50 MiB for an .atq upload.

AI features not working

• Configure an AI provider with a model name and a valid API key under Global Settings.
• For local models, select Ollama and set the custom URL (default http://localhost:11434).
